Watched it and I couldn't agree more! 25 years ago I needed to lose 25 lbs and joined a well known Weight loss company. I lost the 25 lbs. but even more valuable I learned about my relationship with food AND to eat 3 good meals a day. That has stayed with me and to this day I rarely snack. I have learned so much from your videos in the past couple of years about how food impacts the body. Eating healthy and how that impacts health. I am a senior and on no medications because of my dietary choices and walking close to 8000 steps a day. I am slowly getting down to my ideal weight in a healthy way understanding food and its relationship to food. Thank you for your videos.
I am so sad. Something's wrong with me. I stayed off sugars in totality both from refined carbs and fruits. I ate only leafy greens and mutton for 2 weeks straight. With intermittent fasting of 14/10. I had to eat as early as 8 or 9 am because I have ulcers. This Ulcer doesn't allow me to do water fast. So I have to eat just leafy greens with meats, not fatty meats even. Plus taking Orlistat everyday even when I don't eat all the time. No SUGAR at all. Yet I only lost 1kg. In two weeks. Somethings definitely wrong with me. I need help. Before I go crazy. I visit the gym at least 3 times a week and do moderate intensity cardios as I have no much strength for heavy workouts due to not eating carbs. I don't feel hungry, I feel ketones in my system. But I am not burning fat at all. I am frustrated. Seems like all my efforts are in vain. I need help. What is wrong with me??. I currently weigh 110kg, now 109kg after all these. I did a fasting lipid profile, my total Cholesterol was 4.0mmol/L. Triglycerides was 1.7mmol/L. Yet the weight just refused to come off. What else should I do??
@@cosmosokpighe4962 carnivore. Even with ulcers, carnivore is great for healing your body. Check out Dr Ken Berry. He's a real doctor, MD, Family physician. I believe he does only YT now and sees very few patients if any at all. He's helped a ton of people with his free advice.

Dr. Fung is my hero! I almost cried when I read the Obesity Code. I thought 'Finally, someone understands what it's like to be on the low calorie diet merry-go-found!' I lost 50 pounds through intermittent fasting with a 6 hour feeding window and a diet high in healthy fats, protein, and fiber and low in carbohydrates. I've been able to keep the weight off for three years and feel great!
Yes he is ions ahead of conservative nutritionist. Just like you don't get real news from Fox propaganda you don't take health advice from conservative nutritionist. Agreed!
I could agree with you more. I was telling my sister Weight Watchers is an “old-fashioned” style of dieting. She got so upset. You’d have thought she is a WW shareholder! So she will continue joining WW, losing some, gaining more, repeat.
Listening Literally saved my life. I was too late learning. I learned how to reverse my type 2 diabetes and lowered my A1C from 15 to 5.7! My blood sugar was 500 and is now 120 average after a meal and fasting at 90ish. It didn’t matter though because I started getting chest pains.... went in to the hospital and had a quadruple bypass. Its because I reversed my Insulin resistance that made the surgery more effective. 10 Doctors came into my room and many others asking “HOW DID YOU DO THAT?” I explained it like I was Dr. Fung! I think I broke knowledge on them!....... :) It’s been 5 months out and I feel fantastic, I intermittent fast 18:6 and eat zero sugar and eat carbs minimally. I fast for 3 days once a month. (Learn how to break your fast) and started the gym on the weekdays and do 30 min cardio and I hr weights. Off on the weekends...I’ve lost 60lbs and will continue my journey. If I was Rich there’s not enough money to give him. I thank him everyday under my breath.
Congratulations on your success. Can you elaborate on the 10 doctors coming into your room? Was this immediately following your surgery? What aspect(s) of your case did they find so amazing? Was it something about your heart or the dramatic reversal of your diabetes?
I lost 70kilos about 150pounds by fasting for 36 hours twice a week.. also a 10day water fast to boost autophagy.. clean up which is really good.. long fast is addictive.. i felt so good i didn't wanna break fast lol.. our cravings disappear, sugar doesn't call to me anymore... I'm sticking to water as i realized how sugar was effecting my body.. sugar is the enemy.. my mental state has improved a ton.. my fungus on toe disappeared.. my hair used to drop a lot n now it's getting thicker again.. fasting is beautiful..
Wow good job Adam, stories like yours motivate people like me to put in their best that loosing weight is achievable. If I may ask, how long did it take you to loose the 70kg?
@@Meskwe you need to find your own motivation. You can’t do something because someone else did it, you will eventually give up. Find something within and go for it. Remember, weight loss is a marathon not a sprint, it may take some time. Good luck!
I OMAD and Carnivore. Seeing great results. I find it simple. And I’m sorry but easy as well. Someone wrote it’s not easy. I’m off insulin 30 units a day lost 31# 82 years of age. Thanks Dr Fung.
It is easy when you keep those bad carbs out of your diet. Those who haven’t done that are fighting an uphill battle. I am carnivore, OMAD on most days, I keep a short eating window. I continue taking electrolytes for now. Down 36 lbs.💃
If you're eating carnivore, be really careful about polyunsaturated fats that don't come with Omega-3s -- mainly from grain-fed pork and chicken. Too much linoleic acid without stearic acid to counterbalance it can lower your TDEE by as much as 400-500 calories as your body fat becomes PUFA-dominant and puts your body into metabolic torpor. If you're eating mostly grass-fed beef, organ meats, dairy, fish, and crustaceans you don't have to worry about it too much. Or if you're lucky enough to get your chicken and pork raised without grains/seed oil.
@@gloriamaryhaywood2217 I'm not a nutrition scientist, I just find the topic fascinating. TDEE = total daily energy expenditure, in other words how many calories your body uses a day on everything. I haven't been able to measure my sedentary TDEE lately, but since cutting down on polyunsaturated fats about six weeks ago and supplementing with stearic acid -- while already on OMAD/rolling 72h+ fasts for 3+ months -- my body temperature has risen from around 97.5F to 98.0F and I can feel rested off of 6/6.5h of sleep instead of 8. Which indicates to me that my body is coming out of torpor and my TDEE is increasing.
After reading Dr. Fung's book "The Obesity Code" I started alternate day fasting. In not quite seven months I have lost *80 lbs*. And I have done this while weight training and actually gaining muscle. Just cutting calories never worked this way for me. Thank you, Dr. Fung!
This plan works for sure. I had a stroke in Feburary. My weight was 245 pounds. I changed my life style a week after getting out of the hospital. I started with 2 meal a day using a 12 pm to 8 pm window. After a week I realized I was not getting hungry for the first meal. Now i eat only one meal per day around 4 to 6 pm. I have lost 30 pounds. My wife has lost the same amount. We are sleeping and feeling much better. I will eat one meal a day forever. Thank you very much Jason for your teaching and helping me improve my quality of life. I also walk every other day for at least 30 minutes.
This makes perfect sense - it's why each pregnancy raises a woman's set weight slightly too - hormones! Every single medical doctor should be made to watch this.
@@TaylorPhase Not true - food aversions during pregnancy are more common than cravings, you can read studies on it if you google it. Cravings are just given more air time because they're ''cute''. I had food aversions with all 3 of my pregnancies.
I'm currently at 36 hours! It gets easier the more you do it. You can do it guys! Don't give up! I'm a food addict especially sugar and I still trip up. (Mostly when I decide to eat I keep eating) I'm getting better one day at a time and loving how my body feels. Yes, I'm losing weight and I am obese, but the way I feel is worth it alone.
@@Fiery154 awesome! My longest so far is 44 hours. I've been fasting for about 3 weeks now and it easier and better than any diet out there.

Dr Jason Fung once ask the audience, WHY ARE THERE FAT DOCTORS?... that really scare me & make me realise how most doctors lack of knowledge on Health.
@@ahheng6402 thats why I only trust slim, healthy looking doctors like Dr. Fung, Dr. Berg, Dr. Ken Berry. If a doctor looks fat or unhealthy, er shouldn't be taking any health advise from them. I listen to Dr. Fung the most, but the other two give good advice on things like what to eat on Keto, and other health issues, but if any of the other two were to contradict Dr. Fung, that's the day they lose credibility.
@@joemann7971 If you really believe this then nobody should take any advice from you because that’s a really stupid way to go about getting information. Don’t judge a book by it’s cover.
@@corimoon3360 I'm not saying the need to be super fit but need to be healthy weight. Would you take weight lifting advice from a person with no muscles? Use some common sense.

If you do, you're not very smart and nobody should take advice from you.
Dear Dr. Jason Fung, You saved my life. I First heard about You and intermittent fasting on May 13th , 2022, when we were coming back to houston from my son’s college graduation. My brother popped a audio of your book with you and Eve Mayer and Megan Ramos on the car radio “ Life in the FASTING LANE “ (Folks ya have to get this audio or Book). In 3 or 4 hours I was in awe At what I heard. My brother gave me a copy of the book and in 2-3 Days I devoured it. Like MOST I have struggled for years to lose weight. Been diabetic about 15 years. In August 2013 when to the emergency room not feeling right My Blood sugar was 917 and A1C 17+. Since then have been on insulin. Novolin R and Levemir. And have gained weight and my former PCP, 7 yrs. Never discussed any solution, just Keep taking it. For the past few years BS is always up/down , In the last 31 days I’ve cut OUT ALL sweets, for me it was Stevia in my coffee, no more. Eating low carbs, fish or chicken, some beef.
I was previously addicted to carbs and sugars without the slightest idea that I was an addict. I went keto with the help of Jason Fung's videos ( and Dr Ken Berry's too ) and have really turned myself around. Lost heaps of weight via keto and IF (OMAD is best for me I find) and look and feel years younger. My own doctor is a fan of these channels since I introduced him to them and I rarely go a day without looking at one or both of them and reminding myself of what I am doing and why it works. The channels are my new addiction and happy to say it !
After years of frustration and failure, I’m down 50lbs in 6 months thanks to this breakthrough information. The culprit is Insulin, I plan on being at my normal weight in another 6 to 8 months without that much effort. So grateful to have found Dr.Fung.
Great progress! However, don’t look at insulin as a ‘culprit’. Without it you’d be dead. It plays an important role in the body. It’s the processed food your body doesn’t know how to handle that causes the issue. I used to think like you but your body wouldn’t release this hormone it if was bad for you.
The culprit is eating too many calories compared to the amount you used, insulin wasn't an issue before that happened and wont change the fact you need to eat less than you use to drop the weight. If you burn 3000 calories per day and eat only 1500, no insulin will change the fact that you will lose weight fast.
@@cyberfunk3793 you should listen to Dr Fung's 15 march 2016 lecture about viewing the science of food not calories in equalling calories out and metabolic resistance.
Thank you Dr. Fung. I have been following your advice by eating 1 or 2 meals a day. I have lost 25 lbs in 2 months. My starting weight was 230 lbs. Now I'm at 203 lbs. I feel so alert and having so much energy. I'm planning to reach 190 by the end of July 2021.
I’m a certified nutritionist and personal trainer and they do NOT teach this in our certification classes. This information is life changing and so needed! Thank you!!!
Thank you, Dr. Fung! I have been 20-25 pounds overweight for at least three years and cutting calories alone just wasn’t working. I was down to under 400 cal a day and my weight loss still plateaued. Then I found your RUclips channel. I have lost another 10 pounds in the last six weeks with intermittent fasting. I feel great and I’m still able to enjoy food with family and friends. Now I’ve got my husband on board. We are both so excited about our successes in getting back to a healthy weight. I just want to thank you so much. I’m so grateful for your efforts to make this information available.
@@rababwasi3871 I know you asked a different poster, but I have lost 80 lbs in just under 7 months doing mostly alternate day fasting. On fasting days I have black coffee, green or herbal teas, apple cider vinegar and fresh squeezed lemon juice in mineral water. I also have a cup of vegetable or mushroom broth--this last is technically "dirty fasting", but it only has about 20 calories. Usually nothing special with refeeding if I am just fasting every other day--but I do eat very healthy on eating days. No added sweeteners or heavily processed food. Mostly vegetables, whole fruit, legumes, nuts, and seeds, and protein (mostly tofu, tempeh, edamame, legumes, nuts and seeds, as I am vegan). Right now I am on a rare longer fast, and will break my fast with a clear veggie soup--nothing too heavy. Hope this helps!
This video just sort of blew my mind. I didn’t realize that hormones like insulin is what we need to be controlling in order to lower our body set weight.
As a type one diabetic for the last dozen years or so, I can say that I’ve witnessed this firsthand. When I was 36 and first diagnosed I weighed around 205 pounds and over the ensuing dozen years or so I reached 235 pounds. The other thing that increased over those years was the insulin I was injecting. Finally a couple years ago I decided to do some thing “radical” and go on a low-carb diet. Two big things happen with that, one my blood sugar was much more regulated and two I lost a significant amount of weight. Now for the last several months I’ve also incorporated intermittent fasting and reduced my insulin intake to 1/3 of what I was taking before and I have gotten down to 195 pounds. Over all it has been a great experience.
Congratulations! I really think someone who doesn't know what foods to eat and avoid should talk to someone (like you!) with well controlled T1D. You absolutely know what foods cause glucose spikes, which don't, etc.
I’ve always complained that my body likes to be at the weight I am, no matter what I eat or don’t eat. It’s annoying. But this is very encouraging and informative, delivered in a logical way. Sharing ❤
Dr. Jason deserves at least 20 million subscribers if not more. I’m so happy he started to post weekly. I press the like button before the video starts. I bought he’s book on kindle, the obesity code. Definitely worth the investment.
my thermostat was set to fat growing up in a house with lots of processed foods and sugar. its taken me months of intermittent fasting and occasional extended fasts to finally change the setting to normal. thank you dr fung (and sten ekberg).
I follow 16:8 window and eat very low carb diet and I have significantly lost weight. Can't thankyou enough Dr Fung and everyone here who write their transformation stories.
Because of THIS GUY I went Omad 22/2 fasting on November of 2019. Weight was 210, A1C 7.2. I Omad every day 22/2. Today 6/28/21 I’m 180 lbs, A1C 5.9 and my doc cut my atenolol from 10 mg to 5. We eat too often and too much.
@@rajeshroshan2877 I eat carbs a few times a week. Pasta, maybe bread in a sandwich and a beer or two after golf. Once a month pizza. I find that if I “treat” myself it’s like a reward on those days I get hungry but push thru until my eating window.
so thankful for your videos Dr Fung! I've lost 13 pounds in 2 months on low carb combined with IF. I still have 60lbs to go, but for the first time in my life I feel like I understand what's going on in my body. I have the same feeling you get after you figure out a puzzle. It's thrilling!
I have noticed this with myself. I have been on constant yo-yo dieting since my teenage years, and found keto / lowcarb lifestyle the past 3 years. Keto works wonders for me but one time I thought I could accelerate my weight loss just by cutting down my calorie. But instead of losing, my body just stopped at a set weight and it stayed like that for 2 months even with exercise. Frustrating. I found out now 1,500 Calories combined with fasting 20:4 works best for me 😊 Losing 1-2lbs/week slowly but consistent. But this video gave me a clarity. Thank you dr!
Dr Fung’s book The Obesity Code is what really started my education path on nutritional science. I’m eternally grateful to him for sharing his knowledge and being one of the doctors who really care and see the reality of what works and what doesn’t. He also inspired me to start my own channel in the hope to spreading the good news. It definitively needs more videos but I’m slowly working towards that.
Just want to say, i've lost 39kg in the last year, at the start was only a low carb diet, since the start of my fasting journey i lost 29kg of this 39kg, starting with a normal 16:8, and omad now with some 48h black coffee/water/green tea fast. Tnx to Dr. Fung and his video and book i weight like around 20 years ago. So i am really thankfull to him
@@thetree7694 started Jan 2020 with 16:8 , eating healthy but still having carbs. On weekends I have my wine and chips , French fries etc. Monday -Friday I’m flexible with IF. It took me about 8 months. Piece of cake.
Insulin’s affect on the body’s ability to maintain weight is just a thermostat. Thank you so much for sharing your knowledge & wisdom with us who have been struggling 30 plus years.
This video Dr Fung talks about how I went about losing fat and weight. Truth is I never concentrated on losing weight at all, I hardly ever weighed myself. What I did do was concentrate on things to bring my insulin down, I was insulin resistant and prediabetic with belly fat and overweight. So my main concern was to bring down my insulin. The first thing I did was change what I ate, I pretty much was on a carnivore diet (high fat, low to no carbs). Secondly I stopped eating all the time, I did this by eating once a day. My insulin levels started to drop substantially, so did my A1C. Working at bringing my insulin down also brought my blood sugar down reversing my prediabetic state. Now the side effect of that was weight loss and the loss of my body fat, I have a 0.8 waist to hip ratio now and loss over 40 pounds. I concentrated on bringing my insulin down and reversing my insulin resistance, the other things fell in line as a result of me fixing my insulin resistance problem. I went from pushing 200 pounds at 5'7" to now weighing a stable 140 pounds. I still eat a carnivore diet for the most part and I still eat only once a day. Oh, I almost forgot, I also incorporated walking, I walk 6 miles a day 6 days a week. I use one day as a rest day. That's how I did it, Dr Fung is absolutely right on this, I have no doubt that's for sure. I'm healthier now than I ever was, it just took a lifestyle change.
I lost a lot of weight by bringing my insulin down. I still hit a wall. I've had to skip days of eating and eat more protein to put a dent in it since then.
@@CarbageMan I hear ya, I do a prolonged fast for about 3 or 4 days every three months or so. I try for 4 times a year. Fasting has become a way of life for me, I eat once a day and I feel great, it also maintains a dead steady 140 lbs. If I eat what they call a cheat meal now loaded with carbs, I literally feel like crap after I eat. instead of feeling full like I'm use too, i feel all bloated. I can live without eating or drinking sugar no problem.
@@CarbageMan I have four people to thank for my success. Dr. Jason Fung, Dr. Ken Berry, Dr. Robert Cywes And my Family doctor who documented and monitored my journey to wellness. Edit: The best part is I was never charged a dime. Even from my family doctor, I live in Canada Our healthcare is covered so I went and saw my family doctor regularly as he monitored my progress.
@@kosys5338 Yeah, I have mixed feelings about the term "cheat meals." On one hand, it doesn't say much, but the really damaging ones when you go off-plan really hurt, and fit the old saying "when you're cheating, you're ultimately only cheating YOURSELF." I have a bowl of pho about once a quarter, and if I do that, I'm out for a _long_ walk immediately afterward and a few times the next day, just to burn all those carbs out of my system ASAP. Mostly, I've trained myself not to eat sugar and grains or seed oils at all. The tougher struggle has been "keto" treats, nuts and cheese. Basically, I'm at a place where I have to dial back the fat.
@@kosys5338 My first big help was Dr Berg. I read Dr Fung's books, and that gave me the perseverance to stay low-carb and fasted most of the time. Dr Eric Ekberg has really nice detailed videos, too. Some provide a good angle, like Dr Cywes, Shawn Baker, Violet Reveira (keto psychologist) and Thomas Delauer. The recipe-style channels got old fast, and I don't pay too much attention to those because now I eat simple (besides, recipes tend to have more carbs, fat and less whole food.) I find many of the others hit and miss, and there are a few who just come across as either "monetizers" or "everything is borrowed from someone else." Some of these are high profile, like one who calls himself Dr Z. PS: As for the doctor, I found mine mostly unhelpful. He actually MENTIONED low carb, which is why I looked into it, having already heard of it, but I ended up firing him over "standards of care." I'm now seeing a GP that's a low carb diet specialist.
type 2 diabetic here. down 33 lbs in less than 2 months: raw vegan, 1000 calories a day, 1 meal a day with a 48 hour fast once a month, walks and yoga. labs perfect now. working on my BMI. I have 18 lbs to lose before Christmas. I'll make it. Thank you Dr. Fung.
Love Dr. Fung! Granted I didn't have a lot of weight to lose, but I lost 16 lbs during Covid when everyone else was gaining weight! I read his book. I hadn't been able to loose those post menopausal lbs until IF. I can't imagine not being on IF. Love, love learning more & more about it!
That cat made me laugh out loud!!! 33 pounds down so far, headed for 50. Feeling fantastic. I was a chronic and hopeless case... not any more! I am finding it easy to do which is a good thing since low carb plus "low intensity" IF is proving to be the cure for my issues, and I will obviously need to do this forever. No problem! Wishing good success to everyone.
I agree with you -- I am finding it easy and low stress, compared with when I was wondering how I would manage my weight when I am exercising more than enough to be strong, but some other biomarkers were not where I want them.
I lost 55# Within a few mos I stopped being able to maintain and started packing wgt back on. I hadn’t even lost the addl 35# needed. I couldn’t even maintain. My set point is engraved in stone 🤷🏼♀️
@@YeshuaKingMessiah I lost 60#’s following his advice, as soon as I stopped, in one year I had put 40#s back on. Granted I was eating cake and ice cream every day and had stopped walking every day. Now I’m back doing it, down 10#’s in a month.
So glad I found you Dr. Fung! This is my second week of 16/8 fasting. I’ve lost 2 .lbs and I feel better. I was t perfect with what I ate, but I was significantly better! Thank you! I’m going to keep going!
I think the words you need to say constantly to drill into everyone is 1) what you eat and 2) how often you eat, which is not to be confused with "how much you eat."
Amount matters as well--it is just one factor, but still generally an important one. Overeating any food--but especially those that are high calorie or unhealthy to begin with--is harmful and can lead to weight gain.
Your lectures are a big key to my weight loss. From 76kg to 65kg. I'm now doing 18 to 19 hours fasting daily. (Basically 2MAD. From 11am to 12nn, then 3 to 4pm - usually 230 to 330). During the last eating window I eat vegetables and meat so that I am not even hungry by 11am) I love sweets and before IF, I eat any time of the day. Now my sweet intake is minimized. Thank you so so much 💗
Hi. Diagnosed withe T2D last November (female, 73, 185#, good health but overweight or so I thought.) Lost 40 pounds working on another 15. It was easy to lose and great. All I did was brainwash myself morning, noon and night with Dr. Jason Fung's videos. Watched, learned, tried different things. Bottom line intermittent fasting works. Stop eating at 5 pm breakfast after 9 eat better, eat less. Thank you Dr. Fung!!! I feel very good. (A1c started at 12 now at 5.4. Intermittent fasting is just my norm now.
AMAZING DOCTOR. THANK YOU SO MUCH. I started eating once a day and whenever I eat I make sure my meal is 100% natural, wholefoods, homemade. Nothing processed. I already see the results within a few days. I don't feel hungry. Absolutely incredible.
Thank you Doctor Jason! You are my inspiration! I be been doing 16:8 since April. It was easy actually. Today I will finish 72 hours fasting and I m doing just fine! Thank you doctor for your kindness sharing these info to us all! Lots of love and respect from Thailand 🇹🇭 🙏🙏🙏
I’ve been doing it for about a month at 16:8. Sometimes I go longer because I’m not hungry. I have lost 10 lbs. I have about 5 more to go. I never had a problem until menopause when I gained close to 20 pounds.
I LOVE how you never get unlikes, Doctor! Thank you indubitably for your concepts! I have lost a whopping 5 kgs in 40 days!!!!!! And quite healthily so ...
Started IF 16:8 or 18:6 about 4 months ago. Still cheat on weekends. Last 3 weeks did a 24hr fast for 2 weeks and my first 40hr fast this week. Down 35 lbs and feeling great. This info is invaluable!
How about Dr Fung either starts a medical school or his videos be required for MD license so we can actually get real doctors who can do more than writing prescriptions?
The way you explain things is a blessing. Your analogies are second to none. I especially loved the Coal power plant one in the Obesity code. Ive read the obesity code three times and im starting the Cancer code for the second time. THANK YOU Dr Fung.

@@catiemyers3429 His claims about thermodynamics are extremely anti scientific. He claims that if you cut out 500 calories from your diet, you body will now burn 500 less calories. This is an absurd statement
@@loosecannon6142 Try watching the video again and see if you are able to understand the concept of the metabolic rate going down, if I reduce the amount of calories that I consume. (It goes into starvation mode). Whereas if I fast for a while, I will use up my Glucose and glycogen store and then start using the stored fat for energy. There is no problem with the laws of thermodynamics, when I am fasting, by definition, I have created a caloric deficit....
Jason Fung is a fabulous educator and extremely helpful person. I struggle with a fatty liver caused by a lifetime of excess fructose. His teaching and books are an excellent helper for me.
Thank you, Dr. Fung. You are one of the best doctors. I have learned so much just watching a few of your videos. Your understanding of the issues and solutions is impressive. The old way of treating glucose and diet have never worked. But your work is revolutionary. Blessings to you.
Learning the science of fasting is very helpful. I'm just starting to really use intermittent fasting. Yesterday I fasted for 17 hours, working my way to 24 hours (and possibly longer). Thank you Dr. Fung the information in your videos is tremendously helpful and encouraging. Just a reminder, that cat is not a wild animal, and this one clearly has no problem getting food. Cat owners need to be as responsible as dog owners, by not letting their pets annoy neighbors or kill the indigenous fauna. Sorry just a pet peeve of mine.
Thank you Dr. Fung. Your communication skills are above and beyond…. You have the ability to get your message to me in such explicit and simple way and make the hardest concepts so understandable. I can listen and follow you for hours. I tend to be very skeptical of all the “experts” when there’s a sale pitch involved. You, appear genuine and it gives me confidence to trust that what you say is all so true. You’ve got my respect to the point I want to learn to eat and fast as you recommend… it’s going to be a difficult path but one I want to travel. Wish me determination and luck!
I was just binge watching Dr. Fung before going to bed last night, since I'm now seriously getting back into IF after being too wishy-washy in the past year and gained my lost weight back. At night I was thinking that I should search for a video talking about the body set weight, since I have gone back to the exact same size as before I discovered IF - and when waking up this morning, he has uploaded this video!! Thanks Dr. Fung!
This video made so much sense and is true. I know from personal experience. I worked out 6 days a week while eating lower calories and the scale wouldn't move cuz my body adapted to my lifestyle. It drives me crazy when I hear others say its all about calories in and calories out to gain and lose weight!
My personal habit is now simple. 3 hour eating window per day. Move that window around if I can to stop the body into becoming complacent(afternoon, evening or even skip to the next day at noon). It needs to be startled sometimes. I eat low carb but am not as strict about it as before. My one major problem was the cream I put in my coffee. I didn't realize at the time but it raised my insulin leve high enough to counter the fat burning process. I noticed that after reaching a goal, if I fast for about 4 days, it locks in the new set weight. I hope this helps.
That’s interesting about the cream. Was it heavy cream and did it have any added inflammatory ingredients like carrageenan? I go out of my way to buy heavy cream that has nothing but organic cream.
@@boondoggle4820 I like the 35% in my coffee. I thought I was ok by adding less but after a while I was drinking about 5 large decafs during the day. I was also hungrier. Maybe fasting between meals is much more important than I thought. Going to be more vigilant now.
@@mimi1girl2dempsey3During my fasting time for OMAD, 2 days or 3 days, I only have water, green tea & my supplements. If 5 days fasting, add bone broth on 4th & 5th day. I can have a black coffee but not necessarily
I find eating outside the 11am-7pm window to be problematic. Nuts and cheese, too, and definitely "keto" snacks. Even olives can be problematic, it seems. Meat, eggs and non-starchy veg in the above window seems to be when I do best.
@@ahheng6402 I try to live as normal a life as I can. I'll only do 4 day fast after I have lost enough to want to stay there. I still want to lose another 20 lbs but am experimenting to do it as easily as possible. I'm now careful during my daily fast to not ingest anything but black coffee, tea and water. I have been going up a few pounds now and then for the past year but soon get back to my set weight in no time after a small effort. This weight maintenance happened after my last 4 day fast. So now I'm working on losing 10 more pounds and then will fast another 4 or 5 days to lock it in.
Being consistent with your healthy approach(Low carb/less meal frequency) is the key. It really does not matter with healthy approach you choose(keto/low carb/IF) as long as your consistent with the approach , you will see the result eventually. It took 3 years for me to eventually reach to my optimal goal and get rid of that stubborn belly fat.
My wife and I have been doing a 4 day fast 3 day eating cycle the last 3 weeks. (we eased into this cycle) We still need to tweak our Fri-Sun eating some more but it has been really eye opening. We really like your video's, lots of good information. Thank You Jason Fung.
In the end our best eating cycle is one meal a day on day #1 and then only tea on day #2, repeat. Glad to hear you are having an easy time with the eating/fasting. We both have found it easy as well. Cheers.
I don’t simply "like” dr. Jason’s videos....I share them in my personal facebook page and tag myself and my ever getting fatter and fatter friends and family
I fell off the wagon 😩 I gain weight so quickly. I can look at carby foods and gain 15 lbs. no problem. My metabolism is low making weight loss slower than a snail which makes me feel like nothing is happen. No inches or weight gone. But listening to this has given me motivation again to keep trying. Work on keeping insulin low and do more fasting. Thanks Dr Fung!
Trying to explain why an insulin spike comes with anything we eat and that we want fewer of them but you do it much better than I - any video in particular I should point this person to? Love how you use analogies to simplify all of this for us. Pretty soon this we will be seeing millions more starinvg in the US as well as other countries. Thx Dr Fung!
You’re incredible, Dr. Fung! Thank you for clearly explaining everything so succinctly and providing a straight answer by the end of the video. Also love that most videos are about 10 minutes!
Check out my video on how to lose weight automatically - ruclips.net/video/A33eMFcud04/видео.html
Watched it and I couldn't agree more! 25 years ago I needed to lose 25 lbs and joined a well known Weight loss company. I lost the 25 lbs. but even more valuable I learned about my relationship with food AND to eat 3 good meals a day. That has stayed with me and to this day I rarely snack. I have learned so much from your videos in the past couple of years about how food impacts the body. Eating healthy and how that impacts health. I am a senior and on no medications because of my dietary choices and walking close to 8000 steps a day. I am slowly getting down to my ideal weight in a healthy way understanding food and its relationship to food. Thank you for your videos.
I am so sad. Something's wrong with me.
I stayed off sugars in totality both from refined carbs and fruits.
I ate only leafy greens and mutton for 2 weeks straight. With intermittent fasting of 14/10. I had to eat as early as 8 or 9 am because I have ulcers. This Ulcer doesn't allow me to do water fast. So I have to eat just leafy greens with meats, not fatty meats even. Plus taking Orlistat everyday even when I don't eat all the time. No SUGAR at all. Yet I only lost 1kg. In two weeks. Somethings definitely wrong with me. I need help. Before I go crazy. I visit the gym at least 3 times a week and do moderate intensity cardios as I have no much strength for heavy workouts due to not eating carbs. I don't feel hungry, I feel ketones in my system. But I am not burning fat at all. I am frustrated. Seems like all my efforts are in vain. I need help. What is wrong with me??.
I currently weigh 110kg, now 109kg after all these. I did a fasting lipid profile, my total Cholesterol was 4.0mmol/L. Triglycerides was 1.7mmol/L. Yet the weight just refused to come off. What else should I do??
@@cosmosokpighe4962 carnivore. Even with ulcers, carnivore is great for healing your body. Check out Dr Ken Berry. He's a real doctor, MD, Family physician. I believe he does only YT now and sees very few patients if any at all. He's helped a ton of people with his free advice.
@@cosmosokpighe4962 2 lbs in two weeks is not actually bad. Have you kept this up?

Dr. Fung is my hero! I almost cried when I read the Obesity Code. I thought 'Finally, someone understands what it's like to be on the low calorie diet merry-go-found!' I lost 50 pounds through intermittent fasting with a 6 hour feeding window and a diet high in healthy fats, protein, and fiber and low in carbohydrates. I've been able to keep the weight off for three years and feel great!
That is great…
How long did it take to lose the 50 pounds?
Dr Fung is light years ahead of mainstream nutritionists.
its an agenda their pushing.. its not that they dont know
Yes he is ions ahead of conservative nutritionist. Just like you don't get real news from Fox propaganda you don't take health advice from conservative nutritionist. Agreed!
I agree with you.
You are exactly right. He has the clearest understanding of human physiology.
I could agree with you more. I was telling my sister Weight Watchers is an “old-fashioned” style of dieting. She got so upset. You’d have thought she is a WW shareholder! So she will continue joining WW, losing some, gaining more, repeat.
There should be a LOVE button here. Like is an understatement.
Listening Literally saved my life. I was too late learning. I learned how to reverse my type 2 diabetes and lowered my A1C from 15 to 5.7! My blood sugar was 500 and is now 120 average after a meal and fasting at 90ish.
It didn’t matter though because I started getting chest pains.... went in to the hospital and had a quadruple bypass. Its because I reversed my Insulin resistance that made the surgery more effective. 10 Doctors came into my room and many others asking “HOW DID YOU DO THAT?” I explained it like I was Dr. Fung! I think I broke knowledge on them!....... :) It’s been 5 months out and I feel fantastic, I intermittent fast 18:6 and eat zero sugar and eat carbs minimally. I fast for 3 days once a month. (Learn how to break your fast) and started the gym on the weekdays and do 30 min cardio and I hr weights. Off on the weekends...I’ve lost 60lbs and will continue my journey. If I was Rich there’s not enough money to give him. I thank him everyday under my breath.
He gave the knowledge but you did the work! Great job.
Congratulations on your success. Can you elaborate on the 10 doctors coming into your room? Was this immediately following your surgery?
What aspect(s) of your case did they find so amazing? Was it something about your heart or the dramatic reversal of your diabetes?
YAY!!!! ....Now That's what we all looove to hear!!😉😎
Good luck and stay strong on your journey to health and an life full of energy.
Wow! Congratulations! That’s amazing!
I lost 70kilos about 150pounds by fasting for 36 hours twice a week.. also a 10day water fast to boost autophagy.. clean up which is really good.. long fast is addictive.. i felt so good i didn't wanna break fast lol.. our cravings disappear, sugar doesn't call to me anymore... I'm sticking to water as i realized how sugar was effecting my body.. sugar is the enemy.. my mental state has improved a ton.. my fungus on toe disappeared.. my hair used to drop a lot n now it's getting thicker again.. fasting is beautiful..
YESSS!!! D'accord !
Hi, could you tell me how did you eat for the rest of the week? Thanks
Wow good job Adam, stories like yours motivate people like me to put in their best that loosing weight is achievable. If I may ask, how long did it take you to loose the 70kg?
@@Meskwe you need to find your own motivation. You can’t do something because someone else did it, you will eventually give up. Find something within and go for it. Remember, weight loss is a marathon not a sprint, it may take some time. Good luck!
how long did it take you?
He is explaining complicated issues in a no nonsensical simple way which is a gift . Count your blessings Dr. Jason Fung.
I OMAD and Carnivore. Seeing great results. I find it simple. And I’m sorry but easy as well. Someone wrote it’s not easy. I’m off insulin 30 units a day lost 31# 82 years of age. Thanks Dr Fung.
I agree... it IS easy thank goodness!
It is easy when you keep those bad carbs out of your diet. Those who haven’t done that are fighting an uphill battle. I am carnivore, OMAD on most days, I keep a short eating window. I continue taking electrolytes for now. Down 36 lbs.💃
If you're eating carnivore, be really careful about polyunsaturated fats that don't come with Omega-3s -- mainly from grain-fed pork and chicken. Too much linoleic acid without stearic acid to counterbalance it can lower your TDEE by as much as 400-500 calories as your body fat becomes PUFA-dominant and puts your body into metabolic torpor. If you're eating mostly grass-fed beef, organ meats, dairy, fish, and crustaceans you don't have to worry about it too much. Or if you're lucky enough to get your chicken and pork raised without grains/seed oil.
@@maltheopia Heck, you sound like a nutrition scientist!😉 What is TDEE, please?
@@gloriamaryhaywood2217 I'm not a nutrition scientist, I just find the topic fascinating. TDEE = total daily energy expenditure, in other words how many calories your body uses a day on everything.
I haven't been able to measure my sedentary TDEE lately, but since cutting down on polyunsaturated fats about six weeks ago and supplementing with stearic acid -- while already on OMAD/rolling 72h+ fasts for 3+ months -- my body temperature has risen from around 97.5F to 98.0F and I can feel rested off of 6/6.5h of sleep instead of 8. Which indicates to me that my body is coming out of torpor and my TDEE is increasing.
After reading Dr. Fung's book "The Obesity Code" I started alternate day fasting. In not quite seven months I have lost *80 lbs*. And I have done this while weight training and actually gaining muscle. Just cutting calories never worked this way for me. Thank you, Dr. Fung!
Listening to Dr Jason Fung should be require in health classes starting with dietitian/nutritionist all the way to health classes in public schools.
This plan works for sure. I had a stroke in Feburary. My weight was 245 pounds. I changed my life style a week after getting out of the hospital. I started with 2 meal a day using a 12 pm to 8 pm window. After a week I realized I was not getting hungry for the first meal. Now i eat only one meal per day around 4 to 6 pm. I have lost 30 pounds. My wife has lost the same amount. We are sleeping and feeling much better. I will eat one meal a day forever. Thank you very much Jason for your teaching and helping me improve my quality of life. I also walk every other day for at least 30 minutes.
This makes perfect sense - it's why each pregnancy raises a woman's set weight slightly too - hormones! Every single medical doctor should be made to watch this.
Wow. I had never thought of that, but it does make perfect sense! 👍
doubt it. pregnant women just crave junk food a lot more
@@TaylorPhase Not true - food aversions during pregnancy are more common than cravings, you can read studies on it if you google it. Cravings are just given more air time because they're ''cute''. I had food aversions with all 3 of my pregnancies.
@@TaylorPhase I craved steak and spinach.
@@TaylorPhase speaking from experience?
I craved radishes...
I'm currently at 36 hours! It gets easier the more you do it. You can do it guys! Don't give up! I'm a food addict especially sugar and I still trip up. (Mostly when I decide to eat I keep eating) I'm getting better one day at a time and loving how my body feels. Yes, I'm losing weight and I am obese, but the way I feel is worth it alone.
Keep going! I’ve gone up to 48 hours. You are very correct, it does get easier with practice.
@@Fiery154 awesome! My longest so far is 44 hours. I've been fasting for about 3 weeks now and it easier and better than any diet out there.

Thank you you .
2 take home for me
1. Identify foods that spike up insulin and cut down on them
2. Reduce the frequency of eating in a day.
I love how Jason also looks very healthy and well himself. So many doctors look ill but try and give us health advice. ❤️
Dr Jason Fung once ask the audience, WHY ARE THERE FAT DOCTORS?... that really scare me & make me realise how most doctors lack of knowledge on Health.
@@ahheng6402 thats why I only trust slim, healthy looking doctors like Dr. Fung, Dr. Berg, Dr. Ken Berry. If a doctor looks fat or unhealthy, er shouldn't be taking any health advise from them. I listen to Dr. Fung the most, but the other two give good advice on things like what to eat on Keto, and other health issues, but if any of the other two were to contradict Dr. Fung, that's the day they lose credibility.
@@ahheng6402 you can know something and not do it yourself lmao. What scares me is how y’all don’t know that.
@@joemann7971 If you really believe this then nobody should take any advice from you because that’s a really stupid way to go about getting information. Don’t judge a book by it’s cover.
@@corimoon3360 I'm not saying the need to be super fit but need to be healthy weight. Would you take weight lifting advice from a person with no muscles?
Use some common sense. If their advice works, they should lead by example, dummy.
Anyone giving others health advice need to be practicing what they preach. Why would I listen to fat, unhealthy individuals? If you do, you're not very smart and nobody should take advice from you.
Not gonna lie, Im going to be watching this video a few times. And I acknowledge it is absolutely a privilege to do it.
Dear Dr. Jason Fung,
You saved my life. I First heard about You and intermittent fasting on May 13th , 2022, when we were coming back to houston from my son’s college graduation. My brother popped a audio of your book with you and Eve Mayer and Megan Ramos on the car radio
“ Life in the FASTING LANE “
(Folks ya have to get this audio or Book). In 3 or 4 hours I was in awe
At what I heard. My brother gave me a copy of the book and in 2-3
Days I devoured it. Like MOST I have struggled for years to lose weight. Been diabetic about 15 years. In August 2013 when to the emergency room not feeling right
My Blood sugar was 917 and A1C
17+. Since then have been on insulin. Novolin R and Levemir. And have gained weight and my former PCP, 7 yrs. Never discussed any solution, just Keep taking it.
For the past few years BS is always up/down ,
In the last 31 days I’ve cut OUT ALL sweets, for me it was Stevia in my coffee, no more. Eating low carbs, fish or chicken, some beef.
I was previously addicted to carbs and sugars without the slightest idea that I was an addict.
I went keto with the help of Jason Fung's videos ( and Dr Ken Berry's too ) and have really turned myself around. Lost heaps of weight via keto and IF (OMAD is best for me I find) and look and feel years younger.
My own doctor is a fan of these channels since I introduced him to them and I rarely go a day without looking at one or both of them and reminding myself of what I am doing and why it works.
The channels are my new addiction and happy to say it !
After years of frustration and failure, I’m down 50lbs in 6 months thanks to this breakthrough information. The culprit is Insulin, I plan on being at my normal weight in another 6 to 8 months without that much effort. So grateful to have found Dr.Fung.
Great progress! However, don’t look at insulin as a ‘culprit’. Without it you’d be dead. It plays an important role in the body. It’s the processed food your body doesn’t know how to handle that causes the issue. I used to think like you but your body wouldn’t release this hormone it if was bad for you.
The culprit is eating too many calories compared to the amount you used, insulin wasn't an issue before that happened and wont change the fact you need to eat less than you use to drop the weight. If you burn 3000 calories per day and eat only 1500, no insulin will change the fact that you will lose weight fast.
@@NothingButAPeanutToo much makes you fat and you'll eventually become inulin resistant.
@@cyberfunk3793 you should listen to Dr Fung's 15 march 2016 lecture about viewing the science of food not calories in equalling calories out and metabolic resistance.
@@Mina-gm3pg Why? I guarantee if you count your calories and consume say 500 less than you eat, you will lose weight.
Thank you Dr. Fung. I have been following your advice by eating 1 or 2 meals a day. I have lost 25 lbs in 2 months. My starting weight was 230 lbs. Now I'm at 203 lbs. I feel so alert and having so much energy. I'm planning to reach 190 by the end of July 2021.
I’m a certified nutritionist and personal trainer and they do NOT teach this in our certification classes. This information is life changing and so needed!
Thank you!!!
Thank you Dr.Fung for serving Humanity.a true doctor of people.
Thank you, Dr. Fung! I have been 20-25 pounds overweight for at least three years and cutting calories alone just wasn’t working. I was down to under 400 cal a day and my weight loss still plateaued. Then I found your RUclips channel. I have lost another 10 pounds in the last six weeks with intermittent fasting. I feel great and I’m still able to enjoy food with family and friends. Now I’ve got my husband on board. We are both so excited about our successes in getting back to a healthy weight. I just want to thank you so much.
I’m so grateful for your efforts to make this information available.
Wow! Reminds me of my journey except I’m just getting started ❤️
Apple cider vinegar helps with IF by suppressing appetite.

I recommend those 2 doctors to everyone!!!
Hey! Can i know whats your water fastin regimen like? And the refeed?
@@rababwasi3871 I know you asked a different poster, but I have lost 80 lbs in just under 7 months doing mostly alternate day fasting. On fasting days I have black coffee, green or herbal teas, apple cider vinegar and fresh squeezed lemon juice in mineral water. I also have a cup of vegetable or mushroom broth--this last is technically "dirty fasting", but it only has about 20 calories.
Usually nothing special with refeeding if I am just fasting every other day--but I do eat very healthy on eating days. No added sweeteners or heavily processed food. Mostly vegetables, whole fruit, legumes, nuts, and seeds, and protein (mostly tofu, tempeh, edamame, legumes, nuts and seeds, as I am vegan).
Right now I am on a rare longer fast, and will break my fast with a clear veggie soup--nothing too heavy. Hope this helps!
This video just sort of blew my mind. I didn’t realize that hormones like insulin is what we need to be controlling in order to lower our body set weight.
As a type one diabetic for the last dozen years or so, I can say that I’ve witnessed this firsthand. When I was 36 and first diagnosed I weighed around 205 pounds and over the ensuing dozen years or so I reached 235 pounds. The other thing that increased over those years was the insulin I was injecting. Finally a couple years ago I decided to do some thing “radical” and go on a low-carb diet. Two big things happen with that, one my blood sugar was much more regulated and two I lost a significant amount of weight. Now for the last several months I’ve also incorporated intermittent fasting and reduced my insulin intake to 1/3 of what I was taking before and I have gotten down to 195 pounds. Over all it has been a great experience.
Great job!!!
Well done
Congratulations and good for you!! I hope you are proud of yourself for all of your diligence and hard work!!! :-)
Job well done from a Mom of two T1 teens!! From experience, I know your daily challenges and am so happy for you!
Congratulations! I really think someone who doesn't know what foods to eat and avoid should talk to someone (like you!) with well controlled T1D. You absolutely know what foods cause glucose spikes, which don't, etc.
I’ve always complained that my body likes to be at the weight I am, no matter what I eat or don’t eat. It’s annoying. But this is very encouraging and informative, delivered in a logical way. Sharing ❤
Dr. Jason deserves at least 20 million subscribers if not more. I’m so happy he started to post weekly. I press the like button before the video starts. I bought he’s book on kindle, the obesity code. Definitely worth the investment.
my thermostat was set to fat growing up in a house with lots of processed foods and sugar. its taken me months of intermittent fasting and occasional extended fasts to finally change the setting to normal. thank you dr fung (and sten ekberg).
I follow 16:8 window and eat very low carb diet and I have significantly lost weight. Can't thankyou enough Dr Fung and everyone here who write their transformation stories.
Love you Dr Fung! You really are a doctor who is trying to help!
Because of THIS GUY I went Omad 22/2 fasting on November of 2019. Weight was 210, A1C 7.2. I Omad every day 22/2. Today 6/28/21 I’m 180 lbs, A1C 5.9 and my doc cut my atenolol from 10 mg to 5. We eat too often and too much.
You did excellent! Do you keep your carbs low or do you eat a normal amount?
@@rajeshroshan2877 I eat carbs a few times a week. Pasta, maybe bread in a sandwich and a beer or two after golf. Once a month pizza. I find that if I “treat” myself it’s like a reward on those days I get hungry but push thru until my eating window.
Dr Fung is true to his oath.
And he's one of the coolest guys on youtube. :-)
I am afraid nowadays, most of the health professionals' advice is largely governed by pharmaceutical and big food companies.
Felix7 Rjp......so true
Whatever happened to ‘first do no harm’?
so thankful for your videos Dr Fung! I've lost 13 pounds in 2 months on low carb combined with IF. I still have 60lbs to go, but for the first time in my life I feel like I understand what's going on in my body. I have the same feeling you get after you figure out a puzzle. It's thrilling!
I have noticed this with myself. I have been on constant yo-yo dieting since my teenage years, and found keto / lowcarb lifestyle the past 3 years. Keto works wonders for me but one time I thought I could accelerate my weight loss just by cutting down my calorie. But instead of losing, my body just stopped at a set weight and it stayed like that for 2 months even with exercise. Frustrating. I found out now 1,500 Calories combined with fasting 20:4 works best for me 😊 Losing 1-2lbs/week slowly but consistent. But this video gave me a clarity. Thank you dr!
It is so hard to get out of the low calorie mindset.
Dr Fung’s book The Obesity Code is what really started my education path on nutritional science. I’m eternally grateful to him for sharing his knowledge and being one of the doctors who really care and see the reality of what works and what doesn’t. He also inspired me to start my own channel in the hope to spreading the good news. It definitively needs more videos but I’m slowly working towards that.
Just want to say, i've lost 39kg in the last year, at the start was only a low carb diet, since the start of my fasting journey i lost 29kg of this 39kg, starting with a normal 16:8, and omad now with some 48h black coffee/water/green tea fast. Tnx to Dr. Fung and his video and book i weight like around 20 years ago. So i am really thankfull to him

Insulin’s affect on the body’s ability to maintain weight is just a thermostat. Thank you so much for sharing your knowledge & wisdom with us who have been struggling 30 plus years.
This video Dr Fung talks about how I went about losing fat and weight. Truth is I never concentrated on losing weight at all, I hardly ever weighed myself. What I did do was concentrate on things to bring my insulin down, I was insulin resistant and prediabetic with belly fat and overweight. So my main concern was to bring down my insulin. The first thing I did was change what I ate, I pretty much was on a carnivore diet (high fat, low to no carbs). Secondly I stopped eating all the time, I did this by eating once a day. My insulin levels started to drop substantially, so did my A1C. Working at bringing my insulin down also brought my blood sugar down reversing my prediabetic state. Now the side effect of that was weight loss and the loss of my body fat, I have a 0.8 waist to hip ratio now and loss over 40 pounds. I concentrated on bringing my insulin down and reversing my insulin resistance, the other things fell in line as a result of me fixing my insulin resistance problem. I went from pushing 200 pounds at 5'7" to now weighing a stable 140 pounds. I still eat a carnivore diet for the most part and I still eat only once a day. Oh, I almost forgot, I also incorporated walking, I walk 6 miles a day 6 days a week. I use one day as a rest day. That's how I did it, Dr Fung is absolutely right on this, I have no doubt that's for sure. I'm healthier now than I ever was, it just took a lifestyle change.
I lost a lot of weight by bringing my insulin down. I still hit a wall. I've had to skip days of eating and eat more protein to put a dent in it since then.
@@CarbageMan
I hear ya, I do a prolonged fast for about 3 or 4 days every three months or so. I try for 4 times a year. Fasting has become a way of life for me, I eat once a day and I feel great, it also maintains a dead steady 140 lbs. If I eat what they call a cheat meal now loaded with carbs, I literally feel like crap after I eat. instead of feeling full like I'm use too, i feel all bloated. I can live without eating or drinking sugar no problem.
@@CarbageMan
I have four people to thank for my success. Dr. Jason Fung, Dr. Ken Berry, Dr. Robert Cywes And my Family doctor who documented and monitored my journey to wellness.
Edit: The best part is I was never charged a dime. Even from my family doctor, I live in Canada Our healthcare is covered so I went and saw my family doctor regularly as he monitored my progress.
@@kosys5338 Yeah, I have mixed feelings about the term "cheat meals." On one hand, it doesn't say much, but the really damaging ones when you go off-plan really hurt, and fit the old saying "when you're cheating, you're ultimately only cheating YOURSELF." I have a bowl of pho about once a quarter, and if I do that, I'm out for a _long_ walk immediately afterward and a few times the next day, just to burn all those carbs out of my system ASAP.
Mostly, I've trained myself not to eat sugar and grains or seed oils at all. The tougher struggle has been "keto" treats, nuts and cheese. Basically, I'm at a place where I have to dial back the fat.
@@kosys5338 My first big help was Dr Berg. I read Dr Fung's books, and that gave me the perseverance to stay low-carb and fasted most of the time. Dr Eric Ekberg has really nice detailed videos, too.
Some provide a good angle, like Dr Cywes, Shawn Baker, Violet Reveira (keto psychologist) and Thomas Delauer. The recipe-style channels got old fast, and I don't pay too much attention to those because now I eat simple (besides, recipes tend to have more carbs, fat and less whole food.)
I find many of the others hit and miss, and there are a few who just come across as either "monetizers" or "everything is borrowed from someone else." Some of these are high profile, like one who calls himself Dr Z.
PS: As for the doctor, I found mine mostly unhelpful. He actually MENTIONED low carb, which is why I looked into it, having already heard of it, but I ended up firing him over "standards of care." I'm now seeing a GP that's a low carb diet specialist.
type 2 diabetic here. down 33 lbs in less than 2 months: raw vegan, 1000 calories a day, 1 meal a day with a 48 hour fast once a month, walks and yoga. labs perfect now. working on my BMI. I have 18 lbs to lose before Christmas. I'll make it. Thank you Dr. Fung.
Did you reach your goal?
Extremely clear explanation of an issue that we've all experienced. The concept of a Body Set Weight makes a lot of sense.
Love Dr. Fung! Granted I didn't have a lot of weight to lose, but I lost 16 lbs during Covid when everyone else was gaining weight! I read his book. I hadn't been able to loose those post menopausal lbs until IF. I can't imagine not being on IF. Love, love learning more & more about it!
That cat made me laugh out loud!!! 33 pounds down so far, headed for 50. Feeling fantastic. I was a chronic and hopeless case... not any more! I am finding it easy to do which is a good thing since low carb plus "low intensity" IF is proving to be the cure for my issues, and I will obviously need to do this forever. No problem! Wishing good success to everyone.
Congratulations! I want to go from 125 to 105 😊❤️
I agree with you -- I am finding it easy and low stress, compared with when I was wondering how I would manage my weight when I am exercising more than enough to be strong, but some other biomarkers were not where I want them.
I lost 55#
Within a few mos I stopped being able to maintain and started packing wgt back on. I hadn’t even lost the addl 35# needed. I couldn’t even maintain. My set point is engraved in stone 🤷🏼♀️
@@YeshuaKingMessiah I lost 60#’s following his advice, as soon as I stopped, in one year I had put 40#s back on. Granted I was eating cake and ice cream every day and had stopped walking every day. Now I’m back doing it, down 10#’s in a month.
@@YeshuaKingMessiah Did you try going back to intermittent fasting?
Thank you Dr. Fung for your work. Please keep the videos accessible to the public, you saving lives.
Such a clear explanation of the way insulin affects weight. Thanks so much!
So glad I found you Dr. Fung! This is my second week of 16/8 fasting. I’ve lost 2 .lbs and I feel better. I was t perfect with what I ate, but I was significantly better! Thank you! I’m going to keep going!
I think the words you need to say constantly to drill into everyone is 1) what you eat and 2) how often you eat, which is not to be confused with "how much you eat."
Exactly
Bravo! I am completely behind this
That’s exactly true! Couldn’t have said it any better! 👏👌💯‼️
Amount matters as well--it is just one factor, but still generally an important one. Overeating any food--but especially those that are high calorie or unhealthy to begin with--is harmful and can lead to weight gain.
Gosh I love you! I wish I’d found you 30 years ago. You, my friend, are changing lives. Thank you!
Your lectures are a big key to my weight loss. From 76kg to 65kg. I'm now doing 18 to 19 hours fasting daily. (Basically 2MAD. From 11am to 12nn, then 3 to 4pm - usually 230 to 330). During the last eating window I eat vegetables and meat so that I am not even hungry by 11am)
I love sweets and before IF, I eat any time of the day. Now my sweet intake is minimized.
Thank you so so much 💗
Congrats! how long did it tak you to loose the 11 kg?

Hi. Diagnosed withe T2D last November (female, 73, 185#, good health but overweight or so I thought.) Lost 40 pounds working on another 15. It was easy to lose and great. All I did was brainwash myself morning, noon and night with Dr. Jason Fung's videos. Watched, learned, tried different things. Bottom line intermittent fasting works. Stop eating at 5 pm breakfast after 9 eat better, eat less. Thank you Dr. Fung!!! I feel very good. (A1c started at 12 now at 5.4. Intermittent fasting is just my norm now.
Dr. FUNG IS THE MEDICINE THAT I NEVER KNEW I NEEDED!!!
AMAZING DOCTOR. THANK YOU SO MUCH. I started eating once a day and whenever I eat I make sure my meal is 100% natural, wholefoods, homemade. Nothing processed. I already see the results within a few days. I don't feel hungry. Absolutely incredible.
Thank you Doctor Jason! You are my inspiration! I be been doing 16:8 since April. It was easy actually. Today I will finish 72 hours fasting and I m doing just fine! Thank you doctor for your kindness sharing these info to us all! Lots of love and respect from Thailand 🇹🇭 🙏🙏🙏
I’ve been doing it for about a month at 16:8. Sometimes I go longer because I’m not hungry. I have lost 10 lbs. I have about 5 more to go. I never had a problem until menopause when I gained close to 20 pounds.
Dr. Fung thank you i am no longer considered pre diabetic after 3 years of A1C below 6...fasting and keto worked for me...
The leader 👏🏻👏🏻👏🏻 All these other nutritionists are realizing that he is RIGHT❤️ Thank you Dr. Fung.
I LOVE how you never get unlikes, Doctor! Thank you indubitably for your concepts! I have lost a whopping 5 kgs in 40 days!!!!!! And quite healthily so ...
Thank you Dr. Fung, I now have only listened to you book, the complete guide to fasting about 30 times, you're a genius & a gentleman.
Love this Dr. Fung. You r one of my favorite channel when it comes to intermittent fasting. You explain very well🤍🌸
Started IF 16:8 or 18:6 about 4 months ago. Still cheat on weekends. Last 3 weeks did a 24hr fast for 2 weeks and my first 40hr fast this week. Down 35 lbs and feeling great. This info is invaluable!
I love your plain-spoken, yet scientific explanations, Dr. Fung! Thanks for helping us understand the real reason for weight gain.
Authentic doctor
How about Dr Fung either starts a medical school or his videos be required for MD license so we can actually get real doctors who can do more than writing prescriptions?
The way you explain things is a blessing. Your analogies are second to none. I especially loved the Coal power plant one in the Obesity code. Ive read the obesity code three times and im starting the Cancer code for the second time. THANK YOU Dr Fung.
You're the only content creator who I drop what I'm doing to watch. I love your books, and have listened to so many of your talks and podcasts for at least 3 years. Thank you for all you do.
Your gonna thank a guy for spreading anti scientific claims?
@@loosecannon6142 please explain how what he teaches is anti science and we'll go from there.
@@catiemyers3429 His claims about thermodynamics are extremely anti scientific.
He claims that if you cut out 500 calories from your diet, you body will now burn 500 less calories. This is an absurd statement
@@loosecannon6142 Try watching the video again and see if you are able to understand the concept of the metabolic rate going down, if I reduce the amount of calories that I consume. (It goes into starvation mode).
Whereas if I fast for a while, I will use up my Glucose and glycogen store and then start using the stored fat for energy.
There is no problem with the laws of thermodynamics, when I am fasting, by definition, I have created a caloric deficit....
@@grahamedwards6824 Starvation mode does not exist
Jason Fung is a fabulous educator and extremely helpful person. I struggle with a fatty liver caused by a lifetime of excess fructose. His teaching and books are an excellent helper for me.
You have changed my life for the better! I finally can loose weight and have the tools to keep it off. Thank you Dr. Fung! 🙏🏽💕
Same for me!
Yes--same here!
This makes so much sense. I am extremely grateful. Knowledge is POWER, BABY 🔥 I already lost 10 pounds in a month the HEALTHY way 😌🤙
Thank you, Dr. Fung. You are one of the best doctors. I have learned so much just watching a few of your videos. Your understanding of the issues and solutions is impressive. The old way of treating glucose and diet have never worked. But your work is revolutionary. Blessings to you.
Learning the science of fasting is very helpful. I'm just starting to really use intermittent fasting. Yesterday I fasted for 17 hours, working my way to 24 hours (and possibly longer). Thank you Dr. Fung the information in your videos is tremendously helpful and encouraging.
Just a reminder, that cat is not a wild animal, and this one clearly has no problem getting food. Cat owners need to be as responsible as dog owners, by not letting their pets annoy neighbors or kill the indigenous fauna. Sorry just a pet peeve of mine.
Thank you Dr. Fung. Your communication skills are above and beyond…. You have the ability to get your message to me in such explicit and simple way and make the hardest concepts so understandable. I can listen and follow you for hours. I tend to be very skeptical of all the “experts” when there’s a sale pitch involved. You, appear genuine and it gives me confidence to trust that what you say is all so true. You’ve got my respect to the point I want to learn to eat and fast as you recommend… it’s going to be a difficult path but one I want to travel. Wish me determination and luck!
I was just binge watching Dr. Fung before going to bed last night, since I'm now seriously getting back into IF after being too wishy-washy in the past year and gained my lost weight back. At night I was thinking that I should search for a video talking about the body set weight, since I have gone back to the exact same size as before I discovered IF - and when waking up this morning, he has uploaded this video!! Thanks Dr. Fung!
God bless this man!
This information is invaluable. If all doctors were like you, the world would not be as obese and unhealthy as we are. Thank you!
Incredible how Dr Fung make complicated subject easy and very simple to understand
All obesity about thermostat and it is
Thank you Dr Fung
The sense he makes in his talks, translates to an effective weight control life. If your desires for health match your willpower it is simple.
This video made so much sense and is true. I know from personal experience. I worked out 6 days a week while eating lower calories and the scale wouldn't move cuz my body adapted to my lifestyle. It drives me crazy when I hear others say its all about calories in and calories out to gain and lose weight!
Same here.
Thank you Dr. Fung. You are helping so many people. 💜
My personal habit is now simple. 3 hour eating window per day. Move that window around if I can to stop the body into becoming complacent(afternoon, evening or even skip to the next day at noon). It needs to be startled sometimes. I eat low carb but am not as strict about it as before. My one major problem was the cream I put in my coffee. I didn't realize at the time but it raised my insulin leve high enough to counter the fat burning process. I noticed that after reaching a goal, if I fast for about 4 days, it locks in the new set weight. I hope this helps.
That’s interesting about the cream. Was it heavy cream and did it have any added inflammatory ingredients like carrageenan? I go out of my way to buy heavy cream that has nothing but organic cream.
@@boondoggle4820 I like the 35% in my coffee. I thought I was ok by adding less but after a while I was drinking about 5 large decafs during the day. I was also hungrier. Maybe fasting between meals is much more important than I thought. Going to be more vigilant now.
@@mimi1girl2dempsey3During my fasting time for OMAD, 2 days or 3 days, I only have water, green tea & my supplements. If 5 days fasting, add bone broth on 4th & 5th day. I can have a black coffee but not necessarily
I find eating outside the 11am-7pm window to be problematic. Nuts and cheese, too, and definitely "keto" snacks. Even olives can be problematic, it seems. Meat, eggs and non-starchy veg in the above window seems to be when I do best.
@@ahheng6402 I try to live as normal a life as I can. I'll only do 4 day fast after I have lost enough to want to stay there. I still want to lose another 20 lbs but am experimenting to do it as easily as possible. I'm now careful during my daily fast to not ingest anything but black coffee, tea and water. I have been going up a few pounds now and then for the past year but soon get back to my set weight in no time after a small effort. This weight maintenance happened after my last 4 day fast. So now I'm working on losing 10 more pounds and then will fast another 4 or 5 days to lock it in.
You explain it so well! I have dieted all my life and this video finally drove it home--diets do not work. It's the freaking body set weight!!!
Loved this information! I definitely snack through the day and still eat 3 meals. I see what needs to change … now to do it!
Being consistent with your healthy approach(Low carb/less meal frequency) is the key. It really does not matter with healthy approach you choose(keto/low carb/IF) as long as your consistent with the approach , you will see the result eventually. It took 3 years for me to eventually reach to my optimal goal and get rid of that stubborn belly fat.
The more tools the better, exercise and avoiding processed food can also work miracles.
My wife and I have been doing a 4 day fast 3 day eating cycle the last 3 weeks. (we eased into this cycle) We still need to tweak our Fri-Sun eating some more but it has been really eye opening. We really like your video's, lots of good information. Thank You Jason Fung.
In the end our best eating cycle is one meal a day on day #1 and then only tea on day #2, repeat. Glad to hear you are having an easy time with the eating/fasting. We both have found it easy as well. Cheers.
Thank you for ALL of your excellent sessions Dr Fung. You are an amazing communicator with brief on point sessions.
Thank you very much Sir.....your advices changed my life... Humanity needs doctors like you...Stay blessed...
Am loving this channel. I have struggled with my weight my entire adult life and am finding these videos very helpful - especially this one.
I don’t simply "like” dr. Jason’s videos....I share them in my personal facebook page and tag myself and my ever getting fatter and fatter friends and family
Passive 😂....
Dr. Fung is an absolute legend in this field! I'd recommend everyone to read his books. It changed my life! Thank you!!
I fell off the wagon 😩 I gain weight so quickly. I can look at carby foods and gain 15 lbs. no problem. My metabolism is low making weight loss slower than a snail which makes me feel like nothing is happen. No inches or weight gone. But listening to this has given me motivation again to keep trying. Work on keeping insulin low and do more fasting. Thanks Dr Fung!
Same problem here , if we focus on fasting
Hopefully this will help 👍
How are you doing now?
Dr Fung, thank you so much for your simple, effective and well-explained health strategies. You truly are a credit to your profession.
I love these short informative videos…simple strategy to weight loss
I love Dr. Jason he helped me to get my sugar to normal 💟
Trying to explain why an insulin spike comes with anything we eat and that we want fewer of them but you do it much better than I - any video in particular I should point this person to? Love how you use analogies to simplify all of this for us. Pretty soon this we will be seeing millions more starinvg in the US as well as other countries. Thx Dr Fung!
I'm reversing patients w DM2 with this... excellent
This Gentleman seems to have very eccentric and out of the Box explanations and models that are very well suited to describe human physiology
Need a LOVE button for this simple yet thorough explanation. Thank you Dr Jason Fung.
You’re incredible, Dr. Fung! Thank you for clearly explaining everything so succinctly and providing a straight answer by the end of the video. Also love that most videos are about 10 minutes!
