@Ela B Have you seen the 5:2 diet? Many people like to be able to have a small meal a day than none at all. There are many channels about it. I've done it following Keto/Low carb. link to one ruclips.net/video/Tfw4hUSi5LQ/видео.html
This might be shocking to a lot of haters, but guess what when you fast Dr. Fung don't get rich, if anything the big pharmers and the food industry are get poorer when you buy less food. Big thank you to Dr. Fung for actually caring about people's health.
I'm always worried you'll think this kind of video might get repetitive, Dr. Fung. Just want to reassure you that's far from the case as a lot of people need constant encouragement and tips.
Dr. FUNG you continue to make me healthy live a longer life and have hope. I have always had a weight problem but intermittent fasting has saved me and changed my life completely. I have osteoporosis and have had seven bone breaks and was walking with a walker have artificial knees but since I have done intermittent fasting with you I have a normal life. Where I work in my garden I no longer need a cane or walker I feel better my mood is better. You have really made me who I am today and live a full life thank you thank you thank you. Your videos are always uplifting to me and help me. I am almost 76 and will be living longer thanks do you
I grew up in the 70s and 80s. We were alot more active as well. Spending our time playing outdoors not glued to TV screens, computers and cell phones. I loved my childhood!
Right?! I don’t think I knew any overweight kids until my teens; we were too busy playing outside, walking to school etc. And cakes and sweets were a special treat, not a daily snack.
I am currently on day 11 of a water fast and feel like a different person! I have lost 14 lbs, my skin looks 100 per cent better, less wrinkles, clear head, and more energy! I am addicted to sugar and processed food! I was swollen and tired, the fibromyalgia, IBS, and diverticulitis were all flaring up, as was the depression 😞 Today most symptoms are gone from doing this fast!
Dang girl 11 days!?? That's awesome! The longest I've gone is 5 days and I felt like a rockstar 😂 I do have 1 really bad knee, and I noticed the pain was gone after the 3rd day. Go girl! That takes tremendous willpower
Wow that’s amazing! May I suggest you go carnivore. That was the only way I was able to kill my sugar demon. I’ve been carnivore for 4 years now and have amazing healing and weight loss. I do IF now but didn’t in the beginning so my body could heal. I would like to lose that last 10 pounds but I have gone from a size 18 to a size 8/6 so I’m pretty happy. 45 pound weight loss. And I feel great!
@@goolash9991 Thank you! I fasted for 19 days and broke the fast with homemade beef broth, then made the beef broth into beef veggie soup. I am interested in hearing more about carnivore! Congratulations on your weight loss, I lost around 20 lbs and then the weight settled into a 12 lb loss! Not eating sugar and processed food is key for me. Since I quit on February 3rd 2022, I have maintained a much healthier gut convincing me the sugar and processed foods are what made me sick…so sick! I’m still experimenting with different foods but have based my eating around the low fodmap diet for IBS sufferers. Sigh…
@@Forgiven313 thanks! there were hard days and there were easy days, I love giving my body a reset, being on a long fast is fantastic because life gets more depth, other senses kick in, I am more open to seeing and learning. You should try a 10 or 11 day fast, that’s when the real healing begins! Cheers to all of us water fasters!!!
@@jenniferanthony5283 12 pounds for 19 day fast-that’s awesome! I make big batches of homemade beef & poultry broth myself. I’m currently reading Dr. Fung’s book Complete Guide to Fasting and in it he says there are no essential nutrients in carbohydrates (fruits & veggies are carbohydrates too) so you will never run into a carbohydrate deficiency; but you must have protein and fat! Something I knew from all my research. Meat is very nutrient dense and just feeds your body properly. I do not miss carbs or sugar; I LOVE what I eat and I can go longer without eating because of how satiating it is. I can do pull-ups for the first time in my life (I’m a 55 y/o woman) and I can outlast my 22 & 19 y/o stamina & strength wise. My arthritis, inflammation, skin rashes, boils & digestive issues have also disappeared. My BP is normal, too. I was pre-diabetic but no more. Can’t recommend carnivore enough! And it will kill your sugar cravings!
I fast every week for 48 hours from Sunday night to Tuesday Night. During this time, I consume only water. On all other days, I stick to a meal once in a day (dinner) with just coffee or tea (with milk and sugar) during the day time. So far, this routine has worked wonders in my life. I do not consider myself 'strong-willed'. Unlike other fasting and exercise where you have to do something to be healthy, here, you don't have to do anything to remain healthy. I am not advocating against exercise, but exercise just wasn't reducing my weight. Edit: It looks like people haven't read through my comment properly. I am not against exercise. However, the gains from doing it, if you are OBESE, is negligible considering the effort. First bring your weight down to overweight, and then consider taking up exercise. Edit 2: Right now my goal is to be healthy. I am less strict with my diet (two protein rich vegetarian meals a day, 36 hour fasting every week) and I cycle and run almost on a daily basis.
Of course, exercise can make you eat more. It's healthy in a way to keep your body moving and you should combine it with your fasting to optimize your health. Exercise is also critical for longevity. To build a home you need more things than just cement
Exercise is good for cardiovascular system, maintaining or building muscle, keeping blood flow to vital organs, flushing out toxins and such. Exercise is good for mild to moderate weight loss. Diet and nutrient timing is still 90% of weight management.
@@takamonia8204 Not being in Ketosis is not the end of the world. What you need is a habit with which you are comfortable for pretty much the rest of your life. On fasting days I will have nothing but water. But on omad days, I take it easy.
The power of 16-8 Intermittent fasting is measurable, my labs says it all. I used to have high cholesterol despite taking Statins. Now all my labs, blood sugar, cholesterol, trigly and other parameters are within normal. No statins😊🤗 i love the lighter feeling too!
Dr Fung you are a wonderful lifesaver. I’ve battled with obesity all my life. I’m 70 yrs. I must have joined WW 100 times. I even had a gastric bypass, still not much loss. I developed osteoporosis from the GP. Intermittent fasting is my saving grace. I’ve lost 40 lbs so far. I need to lose another 60 lbs. I need to get a hip replacement and my dr wouldn’t give me the operation until I lost 25 lbs. The dr now said ok for the operation. The pain causes me to keep to IF. But I’ll keep going after the operation. Good luck and keep a clean fast. I’m doing one meal a day.
Before I know Dr.Fung I weigh about 79 kgs.(stocky for an asian built)diagnosed as pre-diabetic during my employment medical as Maritime professional.I was alarmed and immediately follow what Dr.Fung told about intermitent fasting.For a month without hesitation,I give up sugar in coffee,high carb foods,processed foods and etc...Tsadaaaa...I lose 10 kgs.In latest medical result 5.4 fbs,normal tryglecirides,normal creatinine level,normal BP 110/80...wow amazing!Truly Gods messenger to mankind.
Thanks Dr Fung, building a basic routine is super easy, I started with a 12 hour window, 3 meals. Now I do 18-20 hours and one meal. Took me a few years but I built the habit 😃🤓
Grateful! RICH counsel, Dr. Fung. I am preparing my mind for maintenance. Have lost 150 pounds. Want to lose 10-20 more. Need a bit more renewed strength to tighten up my routine a bit to keep the loss going. But GRATEFUL for the applications of my “routines” that have brought me this far and to so much healing in my mindset and body. THANK YOU AND YOUR TEAM FOR THE IMPACT you are making in our world. My heartfelt prayer is for my family and friends to open their hearts and minds to these sustainable changes to bring them health.
I designate one day per week as "feast day" and have anything I want for dinner, no holds barred. I generally do two 40-hour fasts per week-- one of them right after feast day. I almost never eat after 8pm and never before noon -- I want my main meal, the evening meal, finished 3 hours or more before going to bed. So at LEAST a 16-hour fast every day. Sometimes I do OMAD. It all depends on how I feel. This routine has been working well for me for several years -- during the first year of which I dropped 40+ lbs. I train on average of 1-2 hours 6 days a week and find no lack of energy on fasting days. That's my scene. If it helps anybody, cool.
Thank you!! You're describing what I wanted to start doing; I have been doing 16:8 for 2 years now and want to add two 40hr fast per week (one on Wednesday and the other on Sunday, after my feast on Saturday), and still maintain the 16:8. Good to know that exercise is still possible. Do you drink water only on your fasts?
@@SolRC It really did, I managed to stop the late night binges/takeouts and it forced me to meal prep; combined with a whole foods plant based diet and exercise, I managed to lose 15kg, and have kept it off. I have reached a plateau now, and am 8kg away from my target weight, a friend suggested I try the 5:2 lifestyle so I'm doing research on it. I've been experimenting here and there with a 40hour fast (mostly on Sundays, on my rest day) but I want to make it a long term thing twice a week, but I was anxious about how it would fit in with the exercise routine (6 days a week) I have established.
Good old common sense and easy to follow ideas. Some channels go into a science lesson or PhD routine. I love that you make it sensible. Thanks so much!! Please keep them coming.
I can't thank you enough Dr. Fung. I started IF in late December after Christmas. I'm down 22 lbs as of this morning. I also finished your book "The Obesity Code" and it has helped me tremendously. Thank you for being a wonderful mentor for me to regain my health back!
Hey Jason Fung. I’ve read three of your books. Started doing fasting about 6 months ago. LCHF diet, 20:4 daily with a 42-48 hour fast once a week (only taking water and green tea). Lost 40 pounds and have more energy than ever. I am 39 years old and now weigh what I weighed in high school. I am enjoying a mental clarity and a focus that I’ve never had before. Thanks for your books and these videos.
Dear Doc, Fung, we owe you a deep gratitude for educating us on natural way of humans!! Feast & fast!!, explaining it medically!! You are one of the Docs who conveyed the message to us, liberated us from food slavery controlled by filthy, greedy FOOD INDUSTRY!!! As a Buddhist, now I understand why Buddha recommended Buddhist monks not to partake any solid food after Noon!! (Monks' physical activity is mainly walking, . .....also matters. .....)
Struggling with weight loss often feels like an uphill battle, where every attempt to make progress comes with its own set of challenges. When I heard the words, "You don't have a food problem; you have a WILL problem," 🔥🔥🔥 it hit me hard. It made me realize that discipline and consistency are the real hurdles, not just the food itself. I’ve decided to commit to a year of Alternate Day Fasting (ADF) to take control of my weight loss journey. My plan is clear: stop eating by 8 p.m. or earlier, then fast for 40 hours straight, breaking the fast at noon two days later. It’s not just about losing weight; it’s about proving to myself that I can stick to a challenging routine and develop the mental strength to succeed. ADF provides structure, reduces decision fatigue, and forces me to confront my habits head-on. By focusing on this rhythm, I aim to reset my relationship with food, foster discipline, and achieve the health and energy I’ve been striving for. This isn’t just about the scale-it’s about transforming my mindset, embracing resilience, and finally taking control of my health.
Doing intermittent fasting about 15 months now usually 20 to 24 hrs. I eat whatever I want as much as I want and am just a 3or4 lbs. more than high school graduation weight and 65 now. I was never huge, and work out 3/5 days a week. but it works for me.
Love these tips and love Dr. Fung. I've been doing intermittent fasting the correct way since mid Nov 2021 , along with a full fasting day and I've lost close to 20 lbs. The key really has been to not snack. I'd been intermittent fasting for over a year prior to discovering Dr. Fung and hadn't lost any weight. In fact, I picked up the COVID "19 lbs". Now I eat more calories, do 2 balanced meals a day (this just works with my schedule) and cut out all snacking. Sometimes I'll save my "snacks" to eat just before or after my meal. I don't feel food deprived and I'm considering this a lifestyle change. Most importantly, it's one that I can sustain without worrying about counting calories or avoiding favorite foods. Another big plus that I'm seeing on my smart scale is improvement in body fat (decreased) and increase in muscle mass and my BMI has hit a healthy range. I'm monitoring bone density as well. Yes, weightless was my #1 priority, but I've shifted that to overall optimal body composition for my age and body frame....a much healthier mindset.
Fasting is so freeing! It’s all about planning and learning about your body. I IF everyday except Fridays,then I fast 38-40hrs every Sunday because I know that’s my busy day. I eat clean and go between Keto,carnivore and allow myself one treat day a month. When the holidays come around I plan longer fast’s and January go carnivore to rid myself of all sugar and carbs. To be able to celebrate with family,friends and food and relax about it is amazing! Thank Dr for everything you do.
"... as long as you are able to fix it with the rest of your week's routine.. " This is key!!! What we do daily is important, but our fasting and eating should be looked at as a whole, the balance of weekly protocol not a "daily caloric intake" etc.
This is a PERFECT adaptation from Brian Tracy's Eat That Frog!!! Every day, every week, every month and every year. For me, every day is a pre-defined fasting window, every week is a monk fast (Saturday PM until Monday AM), every month is an extended fast and every year is to recalibrate my fitness goals. Thanks for being the guy who says my eating patterns are normal!
As a revert muslim i found out by my teacher the Prophet Muhammad fasted 2 days in a week Monday and Thursday, ate 1 to 2 meals a day, sometimes did not see meat for 6 week because of the hardships he and his companions went through, he emphasized the use of having black seed oil, olive oil, figs and apple cider vinegar along with eating fruit or vegetables that are in season. I have lost 7stones over 20 months period Alhamdulilah..❤😁
And also he fasted 3 days a month called the (white days) and prophet Muhammad said the best fasting is the fasting of prophet dawud (david) he fasted alternate days....alhamdulilah We also know once for 3 monthe he never lit fire in his house (meaning no cooking) and he ate dates and drank water only...
I like Fung like I don't normally see myself as someone who likes to get into the science of things but that's where I find myself in most things it just makes it easier to do things when it makes sense in your head like knowing that controlling how the hormones in your body affect your body takes the guesswork away.
Thank you for these great tips Dr. Fung! Been on OMAD for a year! Helped me with my weight loss journey big time. I admit it, not as easy as everyone thinks. Really takes a lot of effort, strong will power, determination and mind set. Experienced different kinds of side effects and hitted a plateau too. But never stop! Learning how your body works really takes time. But once you get the hang of it, you'll feel like a butterfly who just got their wings and now been able to breakthrough your shell and fly high!
Im doing omad since 3 months, on weekends and let my self go crazy with food. No matter what i do minimum 30 min workout. Started 3-4 months ago, -15kg and Never felt better
@@InformWill I try to take bigger meals 3 times a week but still having my fast. And I play with my fasting window. Sometimes I go for 17 or 18 hours if I hit a plateau.
Hi, I have 4 hour eating period, approx 4 PM to 8 PM Tuesday to Sunday and a 48 hour fast through Monday. It is very flexible. I change days and eating window as needed. I still eat one day's worth of food in my window. Eating is so enjoyable again after 20 years of failed calorie restriction!! And I stick to my healthy 160 lb weight. Life is great!!
The 1970s also had vastly less fructose in our diet. I remember, because I was there. Raw hamburger from the local butcher shop or grocery store didn’t have a warning label, because it wasn’t dangerous to handle or eat. Fasting works fine, but let us not forget WHY it is necessary. The food we eat, and what is in it. Routines are definitely one of the most powerful tools. Like every other weekend, Friday morning weigh in. Don’t make my target weight? Fast until Monday lunch. 4 or 5 weekends a year let’s me be good, without requiring perfection Every. Single. Day.
My childhood in the 70s included an afternoon snack of a processed devil food cake and a much sugar add we wanted on our cereal for breakfast... but I wasn't a thin child and struggled with my weight ever since 🙄
@@lisahannah3175 Fructose, and sugar in general, has always been available. The big difference is that the typical American diet now gets as much as 20-25% of calories from fructose.
@@lisahannah3175 Pretty much everything in the center aisles of your grocery store is loaded up. Read the labels, and understand that unless it says "cane sugar only" or something, the listed sugars are mostly fructose. Even cane sugar (table sugar) is "only" 50% fructose.
Hi Dr. Jason Fung! Thank you for all your knowledge, advice, and hard work. Because of you, I was able to lose 20lbs in 2 months! I haven’t been able to lose weight for 9-10 years now. I’m filled with happy tears, because I can actually see progress. I’m incorporating exercise into my schedule now, and am hopeful to continue losing weight. Again, many thanks to you!!! 💗
A year ago today I came across your vlog and started IF. I lost 30 lbs after 8 mos and I plateaued during the holidays. I intend to lose 20 more lbs which I know I can successfully achieve. I feel so much better. I wish I had seen you r vlog earlier. Thank you Dr. Fung!
This was extremely helpful Dr Fung. Habits are key. The idea of adding regular short term “extras” to help with health and weight management is very good, rather than trying to be more restrictive all the time. 16:8, 2 meals a day is easy to maintain. The “extras” done monthly, seasonally or yearly would be the extra boost.
Hey Doc, God bless you.went from 6.2 A1c to 5.9. Glucose from 120 to 107. OMad and 20hr. Fast 6 days a week. 215 lbs. What I weighed when I was 18yrs. old the best shape of my aging life.Iam now 69. Go said I big boned
I read the obesity code December of 2020. I started fasting 12h then, and working out. As of today, Ive lost nearly 50lbs. I fast 12-18h a day. But the thing is - its been sooooooo easy to keep it off. Thats what i appreciate the most about learning this.
IF is amazing, on my way for two months now. I sticked to two-meals a day, just skipping dinner. I shredded off more than a kilo bodyweight already. Coupled with 3 times a week moderate exercise!
Hi Dr Fung , I tried your method last year and i lost around 10 pounds, get my healthy body and confident back. Now that covid hit us, i lose the straight and that 10 lbs come back to me. Last week, i decided to put in some effort and now that i fast 24H , 3lbs is down . I’m so happy that i got to subscribe to your channel, get to understand the fasting and stay healthy with confident. Thank so much ❤️
Wow. Thanks so much for your video. This is so helpful. Also for those reading i bought myself a mini trampoline winter time its hard to be outside here in Canada. This helps when you are fasting and don't want to do or cant do extraneous exercises. Its also good for lymphatic system. God Bless you all.
Dear Dr. Fung My case, I am a 48 year old male, athlete, I do intermittent fasting 18:6 every day of the week (with some exceptions) and my diet is low carb, eating mostly nuts, fish (salmon), avocados, salads, chicken, eggs and dairy (cheese). My BMI is 23.5, my body fat is 13% and my visceral fat is excellent according to impedecia meters. In my last blood test (the previous one was 2 years ago and I was not fasting), my total cholesterol was 290 mg/dL (they did not differentiate between HDL, LDL and VLDL) and triglycerides at 180 mg/dL. I feel better than ever, energetically. I play beach volleyball and I have a lot of energy. In the analysis I observed that the Acetone in urine was 10mg/dL so I was in ketosis since I had been fasting for 20 hours when I did the analysis. Also the Urea was slightly high at 54 mg/dL. I believe that my triglycerides are elevated because my body is in ketogenic mode and uses them as its main source of energy and that is why they are elevated. The liver will be exporting VLDL and my adipocytes will be releasing triglycerides to the liver. I would like to know your opinion about this situation (High Total Cholesterol, TG, and Urea), but the truth is that my condition is better than ever. Thank you very muc
I watch your videos over and over. I started the 16/8 fasting program then modified it to 18/6. It works! My weight loss is steady and I feel great. Some days are harder than others, but I try to keep myself busy - and the time does fly. You do a great job. Thank you!
I've been doing OMAD for about 6 months and lost 65lbs. I've also incorporated weights and walking 10k steps every day. I will eventually go to a 16:8 diet when I hit my goal and will do an extended fast monthly.
Thank you so much for this! After reading The Obesity Code a few years ago, I started intermittent fasting, and lost 80 lbs. But once I hit my target weight, I wasn't quite sure if I was supposed to keep fasting to maintain it. This answers all the questions I've had!
Yes, continue to fast in your week. Your body benefits so much from fasts. It kicks into autophagy after longer fasts, which destroys old cells or cell parts. Also, growth hormones goes up after longer fasts, so that your great body will grow new needed cells using some old bits it took during autophagy. Dr Fung still fasts for the great health benefits.
One or two 36 hour fasts a week should be enough to keep most people on track for maintenance. Some of the many benefits of fasting and low carb diet on the immune system, blood pressure, blood sugar and anti-aging, all backed up by clinical data: Thymus stem cells are regenerated, which suppresses aging and renews the immune system. Fasting stimulates phagocytosis, the ingestion of bacteria and viruses by the immune system. Blood pressure is quickly and dramatically lowered, which is very important for a good outcome with the current pandemic. Fasting increases nitric oxide, which has manifold postive effects like reducing arterial plaque. Weght loss from fasting only loses10% lean tissue and 90% fat compared to the typical 25% lean tissue and 75% fat lost when calorically restricting for long periods. Blood clotting is reduced and blood clots and arterial plaque are reabsorbed into the body. Vitamin D plasma levels are increased, and vitamin D in turn increases autophagy! Blood sugar and insulin are lowered, allowing white blood cells to move more freely throughout the body and do their job. Ideal blood sugar is around 80. Some viruses activate glycolosis (the release of sugar in the body) and clinically it has been shown that decreasing glucose metabolism in the body weakens the influenza virus. The hormone Leptin is an immunomodulator that keeps the body from attacking itself and obesity causes leptin resistance. Fasting very quickly reduces leptin resistance and leptin levels and one day of fasting can cut your leptin levels in half and gets your immune system working properly again! When you move out of MTOR your body shuts down the building blocks of the cell which are used to produce organelles and proteins. This means the mechanisms needed by viruses to replicate are by and large unavailable when you are in a deeply fasted state. It stimulates the AMPK complex and activates autophagy. Autophagy (literally self eating) will cause cells to recycle foreign matter such as viruses and kill cancerous and senescent cells. AMPK does many helpful things in the body including activating the body's antioxidant defenses. Deep ketosis virtually eliminates chronic inflammation in the body. This can offset the life threatening symptoms of viral pneumonia which effectively kills you through inflammation. This also creates BHB ketones in your body, which also help your immune system and anti-oxidative system, especially in the brain. Ketones also provide an additional energy source during infection, which is critical when trying to fight off a bug. In fact you can have as much as three times the total energy available in your blood when you are in deep ketosis, or even more. It increases mitochondrial function and repairs mitichondrial DNA, leading to improved ATP production and oxygen efficiency and thereby making cells better able to fight off infection. Increased mitochondrial function also has the added benefit of increasing your metabolism and cancer prevention! Your body releases interferon which is also triggered by the body during viral attacks to shut down the replication ability of the surrounding cells and stop infections. After 72 hours or more fasted, your body actually recycles large numbers of immune bodies and creates new ones, rejuvenating your entire system. When you fast, this stimulates apoptosis in senescent or genetically damaged cells. This kills these cells off completely. Senescent cells are responsible for the effects of aging and are the root cause of the development of cancer. If it were possible to destroy them all it would completely stop aging and cancer. That is not possible but fasting can help limit these effects by killing off many of the affected cells and limiting the future effects of aging. Fasting also releases BDNF and NGF in the blood which stimulates new nerve and brain cell growth, helping a great deal with diseases like MS, peripheral neuropathy and Alzheimers. In fact, the biochemical precursor to BDNF is beta-hydroxybutyrate, which is the same ketone the body produces to nourish the brain while fasting. Autophagy induced by fasting even helps hair regrow. Dieters losing weight through intermittent fasting show greater reduction in waist size and increase in insulin sensitivity for the same weight lost and alternate day fasters were shown to lose fat while gaining muscle at the same time over a six month period. Fasting has been shown to increase bone marrow volume by 10% and levels of carnosine in the body in as little as a few weeks. Fasting also increases telomere length, negating some of the effects of aging at a cellular level. Eating one meal a day can bring most of these benefits to a lesser degree, and adding a few entire days off from eating per week will have even more effect especially when starting to feel poorly. Exogenous ketones can aid with fasting, making it easier in healthy people and allowing some people with specific issues to fast in spite of them without worrying as much about hypoglycemia. Children, pregnant or nursing women should not fast for periods longer than 16 hours. People with pancreatic tumors or hypoglycemia generally cannot fast at all. Type 1 diabetics can also fast but it is more complicated and should be approached with caution. Those with Addison's disease may also be unable to fast without liberal use of exogenous ketones, depending on severity. If you experience extreme symptoms of some kind, especially dizziness then simply break the fast and seek advice.

Thank you, Dr Fung. You have been appreciated over the months. I've been stuck, by perhaps going too deep into it with the information given on various Drs' channels on here, and not losing (post-menopausal, 5'2", age 53, about a stone-and-a-half to lose still); but this video has helped me step back out and look at the long-term overview, the bigger general picture. This really helps with motivation.
Thanks Dr. Fung! Information is so timely. I started IF24hr...in Dec 2021, now down 30lbs. After holidays, I realized slight weight gain because I wasn't on a routine. Thanks for clarity! I'm back in the game.
Watching this makes me realise I have ZERO routine in my life. Lol. I think about every thing I do consciously, even brushing my teeth, and I still do that everyday btw without fail. But it does take away a tiny bit of my mental power. Why am I so afraid to commit to a routine, I wonder?
Check your intake of protein, perhaps add more daily in the form of grass feed meats, fish, and homemade bone broth (good collagen too). Check your carb intake and reduce if necessary, particularly highly processed carbs like sugar, flour, white rice. Give yourself some time. Make the 12 hours stick and gradually extend it on each end, or whichever end is easier for you. Be kind to yourself.
Dr Fung, I hope you are well. I hope you could do some videos on the following topics, since I cannot seem to find much information on this. 1. Can CKD Patients fast? 2a. How much water should CKD patients drink and how does fasting affect water consumption? 2b. Why are Damaged Kidney Patients told to drink a lot of water, which I believe makes the Kidneys work harder to filter that water and makes them go to the bathroom constantly? Should CKD Patients actually drink less water throughout the day to give the kidneys a rest? 3a. Can CKD patients dry fast and is it dangerous to dry fast with damaged kidneys? I've seen videos that say dry fasting helps the kidneys filter like crazy, and I would think helps the kidneys out. 3b. Adding to the above with water consumption myths, would Dry Fasting actually help with Kidney repair, since when the Kidney isn't filtering all that water all day every day, it has a chance to heal? Similar to how when the body isn't wasting tons of energy digesting 5x a day, the body can use that energy for other things? 4. IS protein actually bad for Kidneys(I've seen videos saying protein is a myth, and when one of my Father's Dr's told him he was leaking protein, the protein he was leaking was a protein I looked up saying it was naturally created by the liver, so the Dr's were saying eating protein would affect it, but his protein leaking went up when he dropped animal proteins, but apparently veggie proteins were higher up, but the dr said the veggie proteins don't affect the protein leak, which non of this made any sense, at the time and still doesn't). My father has been battling with CKD for a few years now, he's tried all sorts of alternative stuff with mixed results (going up points right away, and then gradually dropping a point or so every month), but wont fast and doesn't want to do things other than what traditional medicine tells him too (low protein, low salt, lots of water, lots of veggies). He has started with adding some sea-salt into the diet, but still keeps things low. Thank you!
1. yes 2a lots 2b concentrated toxins destroy the kidney 3a some people do but it is risky 3b dry fasting gives stronger autophagy and other benefits, it's like double fasting. But you can just fast longer on water to get same results and it's safer. 4. no Most of these answers are in his videos if you want to go back and watch, but they do not have dedicated videos.
Thanks Dr. Fung! I've been waiting for this video! I've been working out my fasting, weight maintenance routine since reaching my weight loss goal of 150lbs last year 😁. I love the time freed up by doing OMAD so I still do that but I also love my longer fasts so I'm trying out how often to do those as I'm still losing a bit. I will figure it out I'm sure. I still feel so great and I'm loving my new life. Thanks again for all you do! 🙏😊
Dr. Fung love your videos! I really want to fast on a regular basis but I struggle with not eating during my work day cause my job is a fast passed labor work. I've done work days with fasting and when I get home by the time I get home I over eat and feel fatigued.
Im the same Helen and struggling to drop kilos too. Been Keto for 2.5 years and only the past 6 months I've felt the weight starting to creep back on 😟
Same here - I did a two week food journal for everything I was eating and I fixed it by eating cleaner (and adding walking daily). Hey - you can do it, start now 🖖🖖
IF and no snacking & lower carbs is the best. IF with once a while snacking still works for me but no snacking while on IF is the best as I can see fats reduced tremendously on my whole body. I always feel better when my body fat is reduced (I'm not even obese) because I feel lighter & when I lower my carbs intake (not keto) I feel more energetic. I love IF!
My routine is ground flaxseed meal a slight runny soup consistency I eat this everyday my appetite is under control while fasting then I reset my diet and develop a healthier diet. I'm not eating because I'm hungry but eating for nutrient sake you don't need a strong will but psychologically purposeful on the outcome
Dr Fung this is one of the best videos I have ever watched your content makes things much simpler I was just thinking about extending my fasting over the weekends before I came across this video now I have something to work with
Hi Dr. Fung! Thanks for the new video. I love your useful advice! I’ve been following intermittent fasting for a month and have had many health improvements! I’m really excited by the drastic drop in cravings and the feeling of actually being nourished after my break the fast meal. I’ve have had about ten successful OMAD days. Im still learning IF techniques. I’m really pleased with my progress. Adding saturated fat to my balanced meal also helped; I found that I was not hungry for 5-7 hours after eating my meal, which has never happened to me in the past. I have separated hunger pangs from wanting to eat, also a new experience. I drink Himalayan pink salt (1/4 teaspoon in a cup of water) to help reduce hunger pangs, which works well. Thanks, again, for your help in improving our health!!!! 🤠👍🏼😎
Thanks for all the fasting tips. I am one of your followers and I really appreciate all what you offering us trough your easy and simple videos. I wish to bring to your attention that in many of your videos about fasting you keep mentioning religious fasting including Ramadan as type of fasting that gives the impression to viewers that is a valid and good type of fasting practice. I wish to mention that fasting Ramadan is not fasting on food intake but includes liquid intake too for over 14 and more hours in some countries where days are longer. I believe this type of fasting results in dehydration and could lead to kidney diseases and organs damage. Also during Ramadan all Muslims consume big quantity of unhealthy food with lots of sugary sweets that generally they can't consume during the rest of the year. I hope these information will help you to verify more about Ramadan fasting and if that type of fasting should be mentioned and if that type of fasting could support your studies and can be in line with your researches. Many thanks
he gives examples of different fasting just to show that in every religion it is a practice that is very old and very acceptable. Yes, u r correct about Ramadan, it is a very very unhealthy way to spend a month:):)
Great idea! I think one of my problems is my schedule changes constantly so I can't even eat a meal at the same time everyday. However I do get a weekly 36+ fast in, usually on my busiest day and I do a 5 day fast quarterly.
That's okay to eat your meal at different times. It breaks plateaus and keeps your body guessing. Afterall, we evolved eating whenever food was available...no matter what time of the day it was. Be well 😊🙏
Check out my video 'Fasting: Don't make this critical mistake" - ruclips.net/video/r6vkEIeBj_E/видео.html
@Ela B Have you seen the 5:2 diet? Many people like to be able to have a small meal a day than none at all. There are many channels about it. I've done it following Keto/Low carb. link to one ruclips.net/video/Tfw4hUSi5LQ/видео.html
@Ela B join intermittentfasting on Reddit to have conversations
This might be shocking to a lot of haters, but guess what when you fast Dr. Fung don't get rich, if anything the big pharmers and the food industry are get poorer when you buy less food. Big thank you to Dr. Fung for actually caring about people's health.
And that's it exactly. Calories in Calories out normalizes junk food and that is where the health crisis comes from.
@@LTPottenger doctors don't ever say that
@@Hippy2021 They do all the time.
Don’t assume malevolence where you can assume ignorance.
@@LTPottenger agreed. I watch my caloric intake but definitely notice it when many of those calories come from junk food
I'm always worried you'll think this kind of video might get repetitive, Dr. Fung. Just want to reassure you that's far from the case as a lot of people need constant encouragement and tips.
ABSOLUTELY these weekly videos are very helpful!!!
Also it's helpful for new people like me
Agreed! I look forward to them. They keep me motivated 🙂
Dr. FUNG you continue to make me healthy live a longer life and have hope. I have always had a weight problem but intermittent fasting has saved me and changed my life completely. I have osteoporosis and have had seven bone breaks and was walking with a walker have artificial knees but since I have done intermittent fasting with you I have a normal life. Where I work in my garden I no longer need a cane or walker I feel better my mood is better. You have really made me who I am today and live a full life thank you thank you thank you. Your videos are always uplifting to me and help me. I am almost 76 and will be living longer thanks do you
@@conniebabcock2839 You are an inspiration! Thank you for sharing your story!❤️🙏
I grew up in the 70s and 80s. We were alot more active as well. Spending our time playing outdoors not glued to TV screens, computers and cell phones. I loved my childhood!
Right?! I don’t think I knew any overweight kids until my teens; we were too busy playing outside, walking to school etc. And cakes and sweets were a special treat, not a daily snack.
@@noodlep2547 totally agree!
We need more doctors like Dr. Fung.
I am currently on day 11 of a water fast and feel like a different person! I have lost 14 lbs, my skin looks 100 per cent better, less wrinkles, clear head, and more energy!
I am addicted to sugar and processed food! I was swollen and tired, the fibromyalgia, IBS, and diverticulitis were all flaring up, as was the depression 😞
Today most symptoms are gone from doing this fast!
Dang girl 11 days!?? That's awesome! The longest I've gone is 5 days and I felt like a rockstar 😂 I do have 1 really bad knee, and I noticed the pain was gone after the 3rd day. Go girl! That takes tremendous willpower
Wow that’s amazing! May I suggest you go carnivore. That was the only way I was able to kill my sugar demon. I’ve been carnivore for 4 years now and have amazing healing and weight loss. I do IF now but didn’t in the beginning so my body could heal. I would like to lose that last 10 pounds but I have gone from a size 18 to a size 8/6 so I’m pretty happy. 45 pound weight loss. And I feel great!
@@goolash9991 Thank you! I fasted for 19 days and broke the fast with homemade beef broth, then made the beef broth into beef veggie soup. I am interested in hearing more about carnivore! Congratulations on your weight loss, I lost around 20 lbs and then the weight settled into a 12 lb loss! Not eating sugar and processed food is key for me. Since I quit on February 3rd 2022, I have maintained a much healthier gut convincing me the sugar and processed foods are what made me sick…so sick! I’m still experimenting with different foods but have based my eating around the low fodmap diet for IBS sufferers. Sigh…
@@Forgiven313 thanks! there were hard days and there were easy days, I love giving my body a reset, being on a long fast is fantastic because life gets more depth, other senses kick in, I am more open to seeing and learning. You should try a 10 or 11 day fast, that’s when the real healing begins! Cheers to all of us water fasters!!!
@@jenniferanthony5283 12 pounds for 19 day fast-that’s awesome! I make big batches of homemade beef & poultry broth myself.
I’m currently reading Dr. Fung’s book Complete Guide to Fasting and in it he says there are no essential nutrients in carbohydrates (fruits & veggies are carbohydrates too) so you will never run into a carbohydrate deficiency; but you must have protein and fat! Something I knew from all my research.
Meat is very nutrient dense and just feeds your body properly. I do not miss carbs or sugar; I LOVE what I eat and I can go longer without eating because of how satiating it is. I can do pull-ups for the first time in my life (I’m a 55 y/o woman) and I can outlast my 22 & 19 y/o stamina & strength wise. My arthritis, inflammation, skin rashes, boils & digestive issues have also disappeared. My BP is normal, too. I was pre-diabetic but no more. Can’t recommend carnivore enough! And it will kill your sugar cravings!
I fast every week for 48 hours from Sunday night to Tuesday Night. During this time, I consume only water. On all other days, I stick to a meal once in a day (dinner) with just coffee or tea (with milk and sugar) during the day time.
So far, this routine has worked wonders in my life. I do not consider myself 'strong-willed'. Unlike other fasting and exercise where you have to do something to be healthy, here, you don't have to do anything to remain healthy. I am not advocating against exercise, but exercise just wasn't reducing my weight.
Edit: It looks like people haven't read through my comment properly. I am not against exercise. However, the gains from doing it, if you are OBESE, is negligible considering the effort. First bring your weight down to overweight, and then consider taking up exercise.
Edit 2: Right now my goal is to be healthy. I am less strict with my diet (two protein rich vegetarian meals a day, 36 hour fasting every week) and I cycle and run almost on a daily basis.
Of course, exercise can make you eat more. It's healthy in a way to keep your body moving and you should combine it with your fasting to optimize your health. Exercise is also critical for longevity. To build a home you need more things than just cement
coffe with sugar and milk breaks your ketosis, so in that time you don't fast... you starve (just without feeling hunger)
Exercise is good for cardiovascular system, maintaining or building muscle, keeping blood flow to vital organs, flushing out toxins and such.
Exercise is good for mild to moderate weight loss. Diet and nutrient
timing is still 90% of weight management.
@@takamonia8204 Not being in Ketosis is not the end of the world. What you need is a habit with which you are comfortable for pretty much the rest of your life.
On fasting days I will have nothing but water. But on omad days, I take it easy.
@@takamonia8204 The caffeine would offset the tiny amount of milk and sugar.
The power of 16-8 Intermittent fasting is measurable, my labs says it all. I used to have high cholesterol despite taking Statins. Now all my labs, blood sugar, cholesterol, trigly and other parameters are within normal. No statins😊🤗 i love the lighter feeling too!
Your doctor agreed to cutting the statins? Thought it gonna be forever and ever
Dr Fung you are a wonderful lifesaver. I’ve battled with obesity all my life. I’m 70 yrs. I must have joined WW 100 times.
I even had a gastric bypass, still not much loss. I developed osteoporosis from the GP.
Intermittent fasting is my saving grace. I’ve lost 40 lbs so far. I need to lose another 60 lbs.
I need to get a hip replacement and my dr wouldn’t give me the operation until I lost 25 lbs. The dr now said ok for the operation. The pain causes me to keep to IF. But I’ll keep going after the operation. Good luck and keep a clean fast.
I’m doing one meal a day.
Praying for your success!🙏
Welldone...
Keep going,cheering for you
well done! but if u drop the carbs, u will be even better
Before I know Dr.Fung I weigh about 79 kgs.(stocky for an asian built)diagnosed as pre-diabetic during my employment medical as Maritime professional.I was alarmed and immediately follow what Dr.Fung told about intermitent fasting.For a month without hesitation,I give up sugar in coffee,high carb foods,processed foods and etc...Tsadaaaa...I lose 10
kgs.In latest medical result 5.4 fbs,normal tryglecirides,normal creatinine level,normal BP 110/80...wow amazing!Truly Gods messenger to mankind.
Day 13 on my OMAD going great.... dont even get hungry anymore
Thanks Dr Fung, building a basic routine is super easy, I started with a 12 hour window, 3 meals. Now I do 18-20 hours and one meal. Took me a few years but I built the habit 😃🤓
Isn't it good to change things up especially if you are still menstruating?
Grateful! RICH counsel, Dr. Fung. I am preparing my mind for maintenance. Have lost 150 pounds. Want to lose 10-20 more. Need a bit more renewed strength to tighten up my routine a bit to keep the loss going. But GRATEFUL for the applications of my “routines” that have brought me this far and to so much healing in my mindset and body.
THANK YOU AND YOUR TEAM FOR THE IMPACT you are making in our world. My heartfelt prayer is for my family and friends to open their hearts and minds to these sustainable changes to bring them health.
I designate one day per week as "feast day" and have anything I want for dinner, no holds barred. I generally do two 40-hour fasts per week-- one of them right after feast day. I almost never eat after 8pm and never before noon -- I want my main meal, the evening meal, finished 3 hours or more before going to bed. So at LEAST a 16-hour fast every day. Sometimes I do OMAD. It all depends on how I feel. This routine has been working well for me for several years -- during the first year of which I dropped 40+ lbs. I train on average of 1-2 hours 6 days a week and find no lack of energy on fasting days. That's my scene. If it helps anybody, cool.
Thank you!! You're describing what I wanted to start doing; I have been doing 16:8 for 2 years now and want to add two 40hr fast per week (one on Wednesday and the other on Sunday, after my feast on Saturday), and still maintain the 16:8.
Good to know that exercise is still possible. Do you drink water only on your fasts?
@@nothemba1982 has the 16/8 done well for you in the two years? Why do you want to do longer fast ?
@@nothemba1982 I fasted 7 days in January and ran 40 miles during that week, 8 hours of running. It can be done
I like your feast day, I call it my cheats day, but feast day is more positive.
@@SolRC It really did, I managed to stop the late night binges/takeouts and it forced me to meal prep; combined with a whole foods plant based diet and exercise, I managed to lose 15kg, and have kept it off. I have reached a plateau now, and am 8kg away from my target weight, a friend suggested I try the 5:2 lifestyle so I'm doing research on it. I've been experimenting here and there with a 40hour fast (mostly on Sundays, on my rest day) but I want to make it a long term thing twice a week, but I was anxious about how it would fit in with the exercise routine (6 days a week) I have established.
Fasting has an amazing effect on clarity of the mind!
Good old common sense and easy to follow ideas. Some channels go into a science lesson or PhD routine. I love that you make it sensible. Thanks so much!! Please keep them coming.
Lol true well said 😆 this guys great easy to understand
OMAD for Lent! Spring cleaning for body and soul 💕
Try fasting the whole day on the Fridays as well.
I can't thank you enough Dr. Fung. I started IF in late December after Christmas. I'm down 22 lbs as of this morning. I also finished your book "The Obesity Code" and it has helped me tremendously. Thank you for being a wonderful mentor for me to regain my health back!
That book.... changed my life! ❤️
Hey, I actually started in late December too! I’m also down 20lbs as of now. Congrats on your journey man
Have you listened to The Obesity Code podcasts?
Super motivational!!!’
That's the power of knowledge..it's easy for me to do IF (18-20hrs) everyday, thanks to God, Doc...
Hey Jason Fung. I’ve read three of your books. Started doing fasting about 6 months ago. LCHF diet, 20:4 daily with a 42-48 hour fast once a week (only taking water and green tea). Lost 40 pounds and have more energy than ever. I am 39 years old and now weigh what I weighed in high school. I am enjoying a mental clarity and a focus that I’ve never had before. Thanks for your books and these videos.
Hey Andrew, congratulations! Very cool! I'm looking into this lifestyle as well, can you tell me how long it took you to lose the 40lbs? Cheers.
Congratulations! I am so happy for you.
Hello & Happy Sunday , Dr. Fung. Stay happy, healthy, wealthy, and wise to everyone watching . 😊🤍🌸🎀Have a great day .
Dear Doc, Fung, we owe you a deep gratitude for educating us on natural way of humans!!
Feast & fast!!, explaining it medically!!
You are one of the Docs who conveyed the message to us, liberated us from food slavery controlled by filthy, greedy FOOD INDUSTRY!!!
As a Buddhist, now I understand why Buddha recommended Buddhist monks not to partake any solid food after Noon!! (Monks' physical activity is mainly walking, . .....also matters. .....)
He knows the best ways to get into good health. I felt like he knew my fasting and eating routine!
Struggling with weight loss often feels like an uphill battle, where every attempt to make progress comes with its own set of challenges. When I heard the words, "You don't have a food problem; you have a WILL problem," 🔥🔥🔥 it hit me hard. It made me realize that discipline and consistency are the real hurdles, not just the food itself.
I’ve decided to commit to a year of Alternate Day Fasting (ADF) to take control of my weight loss journey. My plan is clear: stop eating by 8 p.m. or earlier, then fast for 40 hours straight, breaking the fast at noon two days later. It’s not just about losing weight; it’s about proving to myself that I can stick to a challenging routine and develop the mental strength to succeed.
ADF provides structure, reduces decision fatigue, and forces me to confront my habits head-on. By focusing on this rhythm, I aim to reset my relationship with food, foster discipline, and achieve the health and energy I’ve been striving for. This isn’t just about the scale-it’s about transforming my mindset, embracing resilience, and finally taking control of my health.
Doing intermittent fasting about 15 months now usually 20 to 24 hrs. I eat whatever I want as much as I want and am just a 3or4 lbs. more than high school graduation weight and 65 now.
I was never huge, and work out 3/5 days a week. but it works for me.
Love these tips and love Dr. Fung. I've been doing intermittent fasting the correct way since mid Nov 2021 , along with a full fasting day and I've lost close to 20 lbs. The key really has been to not snack. I'd been intermittent fasting for over a year prior to discovering Dr. Fung and hadn't lost any weight. In fact, I picked up the COVID "19 lbs". Now I eat more calories, do 2 balanced meals a day (this just works with my schedule) and cut out all snacking. Sometimes I'll save my "snacks" to eat just before or after my meal. I don't feel food deprived and I'm considering this a lifestyle change. Most importantly, it's one that I can sustain without worrying about counting calories or avoiding favorite foods. Another big plus that I'm seeing on my smart scale is improvement in body fat (decreased) and increase in muscle mass and my BMI has hit a healthy range. I'm monitoring bone density as well. Yes, weightless was my #1 priority, but I've shifted that to overall optimal body composition for my age and body frame....a much healthier mindset.
great job!
Can't wait to get to the point where I can even think about maintenance. 😊
keep going and you will get there. lengthen fast time for faster result.
You can!👍
Me too. You’re not alone!!!! We just have to keep going!
Yes. I am so excited
Fasting is so freeing! It’s all about planning and learning about your body. I IF everyday except Fridays,then I fast 38-40hrs every Sunday because I know that’s my busy day. I eat clean and go between Keto,carnivore and allow myself one treat day a month. When the holidays come around I plan longer fast’s and January go carnivore to rid myself of all sugar and carbs. To be able to celebrate with family,friends and food and relax about it is amazing! Thank Dr for everything you do.
"... as long as you are able to fix it with the rest of your week's routine.. " This is key!!! What we do daily is important, but our fasting and eating should be looked at as a whole, the balance of weekly protocol not a "daily caloric intake" etc.
Well, all I can say is...
Thank you Dr Fung! I lost 20lbs in 2.5 months with a regular 16:8 IF. 😊
This is a PERFECT adaptation from Brian Tracy's Eat That Frog!!! Every day, every week, every month and every year. For me, every day is a pre-defined fasting window, every week is a monk fast (Saturday PM until Monday AM), every month is an extended fast and every year is to recalibrate my fitness goals. Thanks for being the guy who says my eating patterns are normal!
For everything in life, planning is important to success
Very well said
As a revert muslim i found out by my teacher the Prophet Muhammad fasted 2 days in a week Monday and Thursday, ate 1 to 2 meals a day, sometimes did not see meat for 6 week because of the hardships he and his companions went through, he emphasized the use of having black seed oil, olive oil, figs and apple cider vinegar along with eating fruit or vegetables that are in season. I have lost 7stones over 20 months period Alhamdulilah..❤😁
And also he fasted 3 days a month called the (white days) and prophet Muhammad said the best fasting is the fasting of prophet dawud (david) he fasted alternate days....alhamdulilah
We also know once for 3 monthe he never lit fire in his house (meaning no cooking) and he ate dates and drank water only...
Indeed!!
Alhamdulillah...❤
Mashallah brother u are right prophet Muhammad may peace be upon him is perfect example for humankind
I like Fung like I don't normally see myself as someone who likes to get into the science of things but that's where I find myself in most things it just makes it easier to do things when it makes sense in your head like knowing that controlling how the hormones in your body affect your body takes the guesswork away.
Thank you for these great tips Dr. Fung! Been on OMAD for a year! Helped me with my weight loss journey big time. I admit it, not as easy as everyone thinks. Really takes a lot of effort, strong will power, determination and mind set. Experienced different kinds of side effects and hitted a plateau too. But never stop! Learning how your body works really takes time. But once you get the hang of it, you'll feel like a butterfly who just got their wings and now been able to breakthrough your shell and fly high!
Been OMAD since 2018. It’s the only way I can keep the weight off.
Im doing omad since 3 months, on weekends and let my self go crazy with food. No matter what i do minimum 30 min workout. Started 3-4 months ago, -15kg and Never felt better
How did you break through your plateau? Well done for making such great progress!

Hi, I have 4 hour eating period, approx 4 PM to 8 PM Tuesday to Sunday and a 48 hour fast through Monday. It is very flexible. I change days and eating window as needed. I still eat one day's worth of food in my window. Eating is so enjoyable again after 20 years of failed calorie restriction!! And I stick to my healthy 160 lb weight. Life is great!!
The 1970s also had vastly less fructose in our diet. I remember, because I was there. Raw hamburger from the local butcher shop or grocery store didn’t have a warning label, because it wasn’t dangerous to handle or eat. Fasting works fine, but let us not forget WHY it is necessary. The food we eat, and what is in it.
Routines are definitely one of the most powerful tools. Like every other weekend, Friday morning weigh in. Don’t make my target weight? Fast until Monday lunch. 4 or 5 weekends a year let’s me be good, without requiring perfection Every. Single. Day.
Yes!!! Trying to be more restrictive all the time makes it less sustainable.
My childhood in the 70s included an afternoon snack of a processed devil food cake and a much sugar add we wanted on our cereal for breakfast... but I wasn't a thin child and struggled with my weight ever since 🙄
@@lisahannah3175 Fructose, and sugar in general, has always been available. The big difference is that the typical American diet now gets as much as 20-25% of calories from fructose.

@@lisahannah3175 Pretty much everything in the center aisles of your grocery store is loaded up. Read the labels, and understand that unless it says "cane sugar only" or something, the listed sugars are mostly fructose. Even cane sugar (table sugar) is "only" 50% fructose.
Hi Dr. Jason Fung! Thank you for all your knowledge, advice, and hard work. Because of you, I was able to lose 20lbs in 2 months! I haven’t been able to lose weight for 9-10 years now. I’m filled with happy tears, because I can actually see progress. I’m incorporating exercise into my schedule now, and am hopeful to continue losing weight. Again, many thanks to you!!! 💗
A year ago today I came across your vlog and started IF. I lost 30 lbs after 8 mos and I plateaued during the holidays. I intend to lose 20 more lbs which I know I can successfully achieve. I feel so much better. I wish I had seen you r vlog earlier. Thank you Dr. Fung!
This was extremely helpful Dr Fung. Habits are key. The idea of adding regular short term “extras” to help with health and weight management is very good, rather than trying to be more restrictive all the time. 16:8, 2 meals a day is easy to maintain. The “extras” done monthly, seasonally or yearly would be the extra boost.
Trust the Process, Your Time is Coming💯 Make it a Great Day, Remember the Choice is Yours. Stay blessed everyone!💯🌴🤙
Hey Doc, God bless you.went from 6.2 A1c to 5.9. Glucose from 120 to 107. OMad and 20hr. Fast 6 days a week. 215 lbs. What I weighed when I was 18yrs. old the best shape of my aging life.Iam now 69. Go said I big boned
I read the obesity code December of 2020. I started fasting 12h then, and working out. As of today, Ive lost nearly 50lbs. I fast 12-18h a day.
But the thing is - its been sooooooo easy to keep it off. Thats what i appreciate the most about learning this.
That’s what I do I do OMAD Monday through Friday and weekends I do 16:8 and it’s perfect for me.
Love your channel and your practical tips.
IF is amazing, on my way for two months now. I sticked to two-meals a day, just skipping dinner. I shredded off more than a kilo bodyweight already. Coupled with 3 times a week moderate exercise!
Hi Dr Fung , I tried your method last year and i lost around 10 pounds, get my healthy body and confident back. Now that covid hit us, i lose the straight and that 10 lbs come back to me.
Last week, i decided to put in some effort and now that i fast 24H , 3lbs is down . I’m so happy that i got to subscribe to your channel, get to understand the fasting and stay healthy with confident.
Thank so much ❤️
Thank you, Doctor Fung. I really need to listen to this after pigging out during Chinese New Year.
Wow. Thanks so much for your video. This is so helpful. Also for those reading i bought myself a mini trampoline winter time its hard to be outside here in Canada. This helps when you are fasting and don't want to do or cant do extraneous exercises. Its also good for lymphatic system. God Bless you all.
Dr Fung = Brilliant!!!
Thank you Doc. Godbless you
Dear Dr. Fung
My case, I am a 48 year old male, athlete, I do intermittent fasting 18:6 every day of the week (with some exceptions) and my diet is low carb, eating mostly nuts, fish (salmon), avocados, salads, chicken, eggs and dairy (cheese). My BMI is 23.5, my body fat is 13% and my visceral fat is excellent according to impedecia meters.
In my last blood test (the previous one was 2 years ago and I was not fasting), my total cholesterol was 290 mg/dL (they did not differentiate between HDL, LDL and VLDL) and triglycerides at 180 mg/dL. I feel better than ever, energetically. I play beach volleyball and I have a lot of energy.
In the analysis I observed that the Acetone in urine was 10mg/dL so I was in ketosis since I had been fasting for 20 hours when I did the analysis. Also the Urea was slightly high at 54 mg/dL.
I believe that my triglycerides are elevated because my body is in ketogenic mode and uses them as its main source of energy and that is why they are elevated. The liver will be exporting VLDL and my adipocytes will be releasing triglycerides to the liver.
I would like to know your opinion about this situation (High Total Cholesterol, TG, and Urea), but the truth is that my condition is better than ever.
Thank you very muc
I watch your videos over and over. I started the 16/8 fasting program then modified it to 18/6. It works! My weight loss is steady and I feel great. Some days are harder than others, but I try to keep myself busy - and the time does fly. You do a great job. Thank you!
Dr Fung is blessed because he gives information that helps people.❤️
I've been doing OMAD for about 6 months and lost 65lbs. I've also incorporated weights and walking 10k steps every day. I will eventually go to a 16:8 diet when I hit my goal and will do an extended fast monthly.
Thank you, Dr. Fung . I have lost 55lbs since August.😎
Update: i have lost 70lbs
Thanks Dr. Fung! You helped me lose the ~15 lbs. that I would not be able to do on my own. I saw your videos on other channels, btw.
Thank You Dr Fung for all you do.
Just finished my 3rd 48 hour in 3 weeks. Gaining muscle and losing weight. Feeling alert and in control.
great job!
@@LTPottenger thank you. I appreciate it.
Thank you so much for this! After reading The Obesity Code a few years ago, I started intermittent fasting, and lost 80 lbs. But once I hit my target weight, I wasn't quite sure if I was supposed to keep fasting to maintain it. This answers all the questions I've had!
Yes, continue to fast in your week. Your body benefits so much from fasts. It kicks into autophagy after longer fasts, which destroys old cells or cell parts. Also, growth hormones goes up after longer fasts, so that your great body will grow new needed cells using some old bits it took during autophagy. Dr Fung still fasts for the great health benefits.
One or two 36 hour fasts a week should be enough to keep most people on track for maintenance.
Some of the many benefits of fasting and low carb diet on the immune system, blood pressure, blood sugar and anti-aging, all backed up by clinical data:
Thymus stem cells are regenerated, which suppresses aging and renews the immune system.
Fasting stimulates phagocytosis, the ingestion of bacteria and viruses by the immune system.
Blood pressure is quickly and dramatically lowered, which is very important for a good outcome with the current pandemic.
Fasting increases nitric oxide, which has manifold postive effects like reducing arterial plaque.
Weght loss from fasting only loses10% lean tissue and 90% fat compared to the typical 25% lean tissue and 75% fat lost when calorically restricting for long periods.
Blood clotting is reduced and blood clots and arterial plaque are reabsorbed into the body.
Vitamin D plasma levels are increased, and vitamin D in turn increases autophagy!
Blood sugar and insulin are lowered, allowing white blood cells to move more freely throughout the body and do their job. Ideal blood sugar is around 80. Some viruses activate glycolosis (the release of sugar in the body) and clinically it has been shown that decreasing glucose metabolism in the body weakens the influenza virus.
The hormone Leptin is an immunomodulator that keeps the body from attacking itself and obesity causes leptin resistance. Fasting very quickly reduces leptin resistance and leptin levels and one day of fasting can cut your leptin levels in half and gets your immune system working properly again!
When you move out of MTOR your body shuts down the building blocks of the cell which are used to produce organelles and proteins. This means the mechanisms needed by viruses to replicate are by and large unavailable when you are in a deeply fasted state.
It stimulates the AMPK complex and activates autophagy. Autophagy (literally self eating) will cause cells to recycle foreign matter such as viruses and kill cancerous and senescent cells. AMPK does many helpful things in the body including activating the body's antioxidant defenses.
Deep ketosis virtually eliminates chronic inflammation in the body. This can offset the life threatening symptoms of viral pneumonia which effectively kills you through inflammation. This also creates BHB ketones in your body, which also help your immune system and anti-oxidative system, especially in the brain. Ketones also provide an additional energy source during infection, which is critical when trying to fight off a bug. In fact you can have as much as three times the total energy available in your blood when you are in deep ketosis, or even more.
It increases mitochondrial function and repairs mitichondrial DNA, leading to improved ATP production and oxygen efficiency and thereby making cells better able to fight off infection. Increased mitochondrial function also has the added benefit of increasing your metabolism and cancer prevention!
Your body releases interferon which is also triggered by the body during viral attacks to shut down the replication ability of the surrounding cells and stop infections.
After 72 hours or more fasted, your body actually recycles large numbers of immune bodies and creates new ones, rejuvenating your entire system.
When you fast, this stimulates apoptosis in senescent or genetically damaged cells. This kills these cells off completely. Senescent cells are responsible for the effects of aging and are the root cause of the development of cancer. If it were possible to destroy them all it would completely stop aging and cancer. That is not possible but fasting can help limit these effects by killing off many of the affected cells and limiting the future effects of aging.
Fasting also releases BDNF and NGF in the blood which stimulates new nerve and brain cell growth, helping a great deal with diseases like MS, peripheral neuropathy and Alzheimers.
In fact, the biochemical precursor to BDNF is beta-hydroxybutyrate, which is the same ketone the body produces to nourish the brain while fasting.
Autophagy induced by fasting even helps hair regrow.
Dieters losing weight through intermittent fasting show greater reduction in waist size and increase in insulin sensitivity for the same weight lost and alternate day fasters were shown to lose fat while gaining muscle at the same time over a six month period.
Fasting has been shown to increase bone marrow volume by 10% and levels of carnosine in the body in as little as a few weeks.
Fasting also increases telomere length, negating some of the effects of aging at a cellular level.
Eating one meal a day can bring most of these benefits to a lesser degree, and adding a few entire days off from eating per week will have even more effect especially when starting to feel poorly.
Exogenous ketones can aid with fasting, making it easier in healthy people and allowing some people with specific issues to fast in spite of them without worrying as much about hypoglycemia.
Children, pregnant or nursing women should not fast for periods longer than 16 hours. People with pancreatic tumors or hypoglycemia generally cannot fast at all. Type 1 diabetics can also fast but it is more complicated and should be approached with caution. Those with Addison's disease may also be unable to fast without liberal use of exogenous ketones, depending on severity. If you experience extreme symptoms of some kind, especially dizziness then simply break the fast and seek advice.

Lol bro why the phuck you writing long winded comments on RUclips. Get a grip
@@LowTide941 no u
@@LTPottenger Thank you for this! Excellent.
@@NewGoalsNewDreams We can do it!
Star!
The book "Cancer Code" is a great book. The curtain is pulled back by Dr Fung.
The Cancer Code was a difficult read for me. I look forward to rereading it again, more carefully.
@@AzaleaBee Yes, I bought it as an audio book and am listening over and over so it can sink in.
Thank you, Dr Fung. You have been appreciated over the months. I've been stuck, by perhaps going too deep into it with the information given on various Drs' channels on here, and not losing (post-menopausal, 5'2", age 53, about a stone-and-a-half to lose still); but this video has helped me step back out and look at the long-term overview, the bigger general picture. This really helps with motivation.
Thanks Dr. Fung! Information is so timely. I started IF24hr...in Dec 2021, now down 30lbs. After holidays, I realized slight weight gain because I wasn't on a routine. Thanks for clarity! I'm back in the game.
Thank You Doctor Fung 🙏
Thank you forever Dr. Fung.
Thanks Dr. Fung, excellent advice . I just purchased your 3 books , wow, I have learned so much .
I can't thank you enough this is exactly what I need to hear about how to do maintenance 😊😊😊😊🎉
Watching this makes me realise I have ZERO routine in my life. Lol. I think about every thing I do consciously, even brushing my teeth, and I still do that everyday btw without fail. But it does take away a tiny bit of my mental power. Why am I so afraid to commit to a routine, I wonder?
Thank you. I keep bouncing routines and never stick with it. This has definitely help to get a routine
Thank you for all you do!
Thank you. This was a big help in my fasting. Can't get past 12 hours. Am still striving too.
keep cutting carbs and slowly extending the time and you'll get there.
Check your intake of protein, perhaps add more daily in the form of grass feed meats, fish, and homemade bone broth (good collagen too). Check your carb intake and reduce if necessary, particularly highly processed carbs like sugar, flour, white rice. Give yourself some time. Make the 12 hours stick and gradually extend it on each end, or whichever end is easier for you. Be kind to yourself.
Dr Fung, I hope you are well.
I hope you could do some videos on the following topics, since I cannot seem to find much information on this.
1. Can CKD Patients fast?
2a. How much water should CKD patients drink and how does fasting affect water consumption?
2b. Why are Damaged Kidney Patients told to drink a lot of water, which I believe makes the Kidneys work harder to filter that water and makes them go to the bathroom constantly? Should CKD Patients actually drink less water throughout the day to give the kidneys a rest?
3a. Can CKD patients dry fast and is it dangerous to dry fast with damaged kidneys? I've seen videos that say dry fasting helps the kidneys filter like crazy, and I would think helps the kidneys out.
3b. Adding to the above with water consumption myths, would Dry Fasting actually help with Kidney repair, since when the Kidney isn't filtering all that water all day every day, it has a chance to heal? Similar to how when the body isn't wasting tons of energy digesting 5x a day, the body can use that energy for other things?
4. IS protein actually bad for Kidneys(I've seen videos saying protein is a myth, and when one of my Father's Dr's told him he was leaking protein, the protein he was leaking was a protein I looked up saying it was naturally created by the liver, so the Dr's were saying eating protein would affect it, but his protein leaking went up when he dropped animal proteins, but apparently veggie proteins were higher up, but the dr said the veggie proteins don't affect the protein leak, which non of this made any sense, at the time and still doesn't).
My father has been battling with CKD for a few years now, he's tried all sorts of alternative stuff with mixed results (going up points right away, and then gradually dropping a point or so every month), but wont fast and doesn't want to do things other than what traditional medicine tells him too (low protein, low salt, lots of water, lots of veggies). He has started with adding some sea-salt into the diet, but still keeps things low.
Thank you!
1. yes 2a lots 2b concentrated toxins destroy the kidney 3a some people do but it is risky 3b dry fasting gives stronger autophagy and other benefits, it's like double fasting. But you can just fast longer on water to get same results and it's safer.
4. no
Most of these answers are in his videos if you want to go back and watch, but they do not have dedicated videos.
Great pointers. Thank you
Thanks Dr. Fung! I've been waiting for this video! I've been working out my fasting, weight maintenance routine since reaching my weight loss goal of 150lbs last year 😁.
I love the time freed up by doing OMAD so I still do that but I also love my longer fasts so I'm trying out how often to do those as I'm still losing a bit. I will figure it out I'm sure. I still feel so great and I'm loving my new life. Thanks again for all you do! 🙏😊
great job!
@@LTPottenger Thanks! And thanks for your information too😊
Dr. Fung love your videos! I really want to fast on a regular basis but I struggle with not eating during my work day cause my job is a fast passed labor work. I've done work days with fasting and when I get home by the time I get home I over eat and feel fatigued.
A New Dr. Fung video🎉 always helpful & a gift
This was great! Very helpful!
Thank you Jason! This topic has been on my mind for the past week. You really gave me some insight.
Thank you Jason , wonderfully explained.
Really needed this.
Great advice! I am slowly putting weight on even tho keto and 16:8, so I'm desperate to stop the rot! Will try these tips immediately, thks Dr Fung.
Im the same Helen and struggling to drop kilos too. Been Keto for 2.5 years and only the past 6 months I've felt the weight starting to creep back on 😟
Same here - I did a two week food journal for everything I was eating and I fixed it by eating cleaner (and adding walking daily).
Hey - you can do it, start now 🖖🖖
@@GS-uy4xo I walk every day, cook all my own food and have been using carb manager on and off for 2.5 years 😔
Thank you Dr. Fung! I'm doing 20:4 for 2 weeks and i have lost 2.5 kg. Still long way to go. My eating period is from 1:30-6pm.
IF and no snacking & lower carbs is the best. IF with once a while snacking still works for me but no snacking while on IF is the best as I can see fats reduced tremendously on my whole body. I always feel better when my body fat is reduced (I'm not even obese) because I feel lighter & when I lower my carbs intake (not keto) I feel more energetic. I love IF!
Thank you again for a very helpful and practical video. I appreciate you more than you can know.
My routine is ground flaxseed meal a slight runny soup consistency I eat this everyday my appetite is under control while fasting then I reset my diet and develop a healthier diet. I'm not eating because I'm hungry but eating for nutrient sake you don't need a strong will but psychologically purposeful on the outcome
Consider watching Dr Ken Berrys' videos on lowering tester one and how flax seed meal is shown to reduce T levels in men.
Always awesome. Thank you Dr Fung
Dr Fung this is one of the best videos I have ever watched your content makes things much simpler
I was just thinking about extending my fasting over the weekends before I came across this video now I have something to work with
Hi Dr. Fung! Thanks for the new video. I love your useful advice! I’ve been following intermittent fasting for a month and have had many health improvements! I’m really excited by the drastic drop in cravings and the feeling of actually being nourished after my break the fast meal. I’ve have had about ten successful OMAD days. Im still learning IF techniques. I’m really pleased with my progress. Adding saturated fat to my balanced meal also helped; I found that I was not hungry for 5-7 hours after eating my meal, which has never happened to me in the past. I have separated hunger pangs from wanting to eat, also a new experience. I drink Himalayan pink salt (1/4 teaspoon in a cup of water) to help reduce hunger pangs, which works well. Thanks, again, for your help in improving our health!!!! 🤠👍🏼😎
I lost 1.7 Kg in less than a week, now the hard part starts - carry on loosing weight !
Great and much needed topic.. thanks so much
Thank you so much for these videos 🙏 😭
I like the yearly routine. That helps me immeasurably. Thanks Dr Jason Fung. You are the best
Very True and inspiring video...
A very Thanks from my heart to Dr. Fung..God Bless You and Your Family..👍🙏🙏
You are God sent to Humans...
Very useful content. Thanks Dr. Fung.
Thanks for all the fasting tips. I am one of your followers and I really appreciate all what you offering us trough your easy and simple videos. I wish to bring to your attention that in many of your videos about fasting you keep mentioning religious fasting including Ramadan as type of fasting that gives the impression to viewers that is a valid and good type of fasting practice. I wish to mention that fasting Ramadan is not fasting on food intake but includes liquid intake too for over 14 and more hours in some countries where days are longer. I believe this type of fasting results in dehydration and could lead to kidney diseases and organs damage. Also during Ramadan all Muslims consume big quantity of unhealthy food with lots of sugary sweets that generally they can't consume during the rest of the year.
I hope these information will help you to verify more about Ramadan fasting and if that type of fasting should be mentioned and if that type of fasting could support your studies and can be in line with your researches. Many thanks
he gives examples of different fasting just to show that in every religion it is a practice that is very old and very acceptable. Yes, u r correct about Ramadan, it is a very very unhealthy way to spend a month:):)
Excellent
Great idea! I think one of my problems is my schedule changes constantly so I can't even eat a meal at the same time everyday. However I do get a weekly 36+ fast in, usually on my busiest day and I do a 5 day fast quarterly.
That's okay to eat your meal at different times. It breaks plateaus and keeps your body guessing. Afterall, we evolved eating whenever food was available...no matter what time of the day it was. Be well 😊🙏
It's actually good to vary the eating time as long as you do not binge
Great vid Dr. Fung! Please keep up the great work
Great advice it has been working well for me. Thanks!!!
