Thank you Jason. Two years ago when I was diagnosed with t2 diabetes my A1C number was 6.8. Following your fasting advise and eating much healthier I've dropped a little over 40lbs and my recent A1C number is 5.5. Thank you🙏
How do you safely get through the next day on little or no sleep? Do you work? Or drive? Do you live alone? If I tried house cleaning, I'd wake everyone up
I do the same! Only differences from you, I’m listening audiobooks and set up listening for 15 or 30 min and after that I’m sleeping like a baby all night!
@@cassieoz1702 I get up at 4 AM and work for eight hours and yes, I drive 40 minutes each way I take supplements I only drink water I try to get tired I work on my feet all day I walk in average of 7 miles a day. I find that if I’m tired at the end of the day I will sleep.
I remember the acid reflux thing from a Japanese study, showing that the reason of the acid goes back up, is because the sphincter from the esophagus into the stomach doesn't close. It doesn't close because the pH of the stomach is too high, so the liver just keeps dumping bile. The reason lemon juice and vinegar work so well, is because it quickly drops the pH of your stomach, and that sphincter closes. Problem solved.
My brother has had the worst case of acid reflux I have seen. Doctors were worried that he may develop cancer later in life due to the constant destruction of the cells in his esophagus. I also have had acid reflux for years and years. Well, we both watched Dr Ekberg's video on acid and what can help. Like you said, simple, just drink some apple cider vinegar (much higher acid level than regular vinegar) with water daily. Yup, neither of us has any problem with acid anymore. Guess all those Tums we took was the exact opposite of what we needed.
@@Mhantrax, the specialist is worried about me for the same reason. May ask at what time do you drink it? Waking up or before meals? Thanks in advance.
This man's advice on various fasting regimes and how to deal with the variety of issues that different people encounter when fasting I would say is probably the best I've seen or read. Jason will give you the information without the hype. I, for one, abhor all kinds of hype where things are accentuated or overly emphasised for effect. It was in fact Jason that introduced me to fasting. You see, we grow up thinking food is essential, which it is, but you would hear very few say that the body can function just as well, if not better, if you leave it to burn the fat you've stored. We tend to think that without food the body would be deprived of vitamins, minerals and all the essentials. That is true if you haven't any stored fat i.e. you're not obese or overweight. But if you are obese or overweight, it means you have plenty and you can therefore fast for many days without the worry that you're going to die. The body is a wonderful machine, it is a miraculous piece of engineering that can feed itself and heal itself. Even though we often throw so much abuse at it (mostly through eating too much of sugar based stuff), it gives us plenty of opportunity to repent and reverse the damage. Fasting is a wonderful way to do that. Unless you're on some sort of serious medical regimen where food is essential (can't think of one right now), fasting is by far THE BEST and FASTEST way to lose weight and achieve a healthy body.
I feel the same. However, the other guy I absolutely love and trust is Dr. Sten Ekberg. He is a fabulous teacher and his, "lessons," are almost like a college course from a professor who cares about teaching instead of only research. I highly recommend him!
Yes, I agree. Dr. Fung's explanations are quite good and he covers issues that others skip -- for example, the idea of ingesting something acidic to remedy reflux. I like his presentation style -- he can be quite technical and detailed, but explains things in a way that makes sense to non-medical ppl like me. He really helps me understand the nuances that less-informed YT'ers skip over.
I sleep really well when I fast!! It's the best thing about fasting. I have severe insulin resistance and type 2 diabetes and every morning around 7 a.m. my blood sugar shoots to almost 300 whether I have been fasting for 10 hours or 36 hours. I like Dr. Fung's explanation of why this happens. I've got a ways to go still but I'm down 30+ pounds and using 70% LESS insulin injections now. I love doctors like Jason and Ben Bikman. I wish they were around 15-20 years ago!
@SandraCarterAtHomeNC It's been a yr, how your sugar now? I've been doing this since January and still not much on the glucose front. Just wondering how long did it take for you?
Yeah, after 41 hours I finally got my glucose down to 149 and it wouldn't budge. I cleaned up my diet, eating very little carbs and my sugar is still very high. I've been doing this since 1/28/24. All my other labs have been much improved and have lost 14 pounds.
I’m fasting almost every month, it’s the headache make me worst. I have done extreme fasting for a week and with coffee I stretched to a month without any food. Now I’m back again after a year without fasting. Never felt great, your obesity code give me life🙏🏻
I've been fasting for over 2 years now, and noticed constipation/diarrhea (for me) is usually an indicator that my fiber intake was too low. Ever since I paid more attention to adding plenty of fiber to my meals, my digestion issues are completely resolved.
That's great! I stopped all fiber and my issues resolved. I never burp or have gas. No painful stools. I mean absolutely zero fiber. It's great! Funny how all people are so different
Same here, I actually moved to Europe and started eating fruit every single day, I can't go without it and I absolutely reversed my years by a decade. Combination of fibre and fasting boosted my energy levels and fasting alone completely fixed my sleeping schedule and alertness.
My road to insulin resistance recovery has been long and winding with many twists and turns. A big breakthrough has been castor oil packs over the liver. The skin problems that I experienced for decades that included inflamed skin and weeping eczema were explained by toxic fatty liver. When I was younger I worked with toxic chemicals for ten years. At the same time I was a sugarholic. It seems probable that fasting caused too rapid a release of toxins. I now wear castor oil packs most of the time and have limited fasting for the interim. Literally within days sores on my scalp and face that I have had for decades completely cleared up.
I'm going into 3 months of IF. Wow I'm addicted!!!!. Results are amazing. Hydration is key, lots of water. This week I'm going no meat, little fish, loads of veggies for my feeding window. I'm not use to feeling my bones on my knees, shoulders, hips, which means I'm on the right page, fasting is working wonders. Can't wait to do over my labs...thank you Dr. Fung
Some may want/need to watch more of his videos before you fast. It all depends on how strict you want to be on a fast. I still have my one cup of morning coffee when fasting. I don’t get all crazy about it. That’s just me though and yes, I’ve lost weight
Same here - not having my tea and coffees in the morning, with milk, is a deal breaker for me! I think I've lost a little weight - I don't dare weigh myself as that would REALLY get me depressed - but I do feel better when I do 16/8 so it's worth persevering! I hope I lose weight as you have - that would be WONDERFUL!!
@@andersonomo597 , 100% same. Coffe, tea, even bullet proof coffe is a go, as long as it helps to keep going through the hours. And I have the same relationship with scale - after all the work I put in working out, building muscle, eating healthy, and now fasting, when the scale doesn’t budge at all it’s very depressing and all I want to do is to throw tge towel. But then i realize how loose my pants feel and good I feel and i just tell myself that it’s worth it! The scale and my body just are playing this joke on me like saying: you won’t see your weight drop no matter how stubborn you are - we win! The only time i get my weight is when i go for my physical- and i hate stepping on the scale then cause I already know :))
@@ilonaghine9690 I've just listened to 2 REALLY interesting interviews on "The Diary of a CEO " featuring Dr Tim Spector and Dr Giles Yeo. There's so much info there about calories and blood sugar spikes and how different foods affect people differently. Highly recommend listening to both - there's nothing 'visual' in either interview so you can easily listen while doing other things. Both interviews have made me re-think how I'm eating - I'll focus more on high fiber foods, more vegetable varieties and not no-carbs but fewer carbs. Cost = ZERO, benefits = can't hurt, worth trying!! And yes, the joy of looser pants, for me that's important, not the number which will send me into a deep funk!! Best wishes for success in your efforts!!
The salt definitely helps the headaches. And for me it works instantly- the headache goes away in 5 min after I add a Hymalayan salt to my water. Thank you, Dr.Fung!
Salt helps us retain a healthy amount of water. If we don't have enough, we can get severely dehydrated and our brain literally shrinks, causing negative pressure. PS: In this way, it is similar to caffeine, in which going cold turkey may cause a change in brain pressure that results in headaches.
@@CarbageMan , thank you for explaining the effect. I wasn’t sure why it helped but when i got the headaches I was like let’s give it a try and amazingly it worked. Also, i tend to drink lots of coffee and I just saw it from someone’s post that coffee during fast can cause headaches more severely than if you just drink water.
Try Apple cider vinegar, a couple of Tablespoons in some water twice a day. It seems counter intuitive, but I have full blown GERD Gastric Reflux disease. And doing it for a few months actually cured my disease. So give it a try, you can thank me later!
Sir I have been doing 18:06 hours of fasting every day that 6 hours of food window and 18 hours of water fasting and I have been doing it’s from past 12 months and I have doing good gym workout at gym “ hope I m Doing well intermittent fasting “ as I m feeling very good 👍🏻
The best adjustment that I made was instead of adding salt and potassium to my water, I just take a 3/4 teaspoon of pink salt in the morning and/or evening. I found that the chalky taste of water after three days would make any further fasting a big challenge. By taking the salt directly, I can continue drinking fresh water all day without the hesitation to stay hydrated. I can do five day fasts without batting an eye. I dropped 30lbs in five weeks at the end of last year. I've just initiated a four week regiment. I should drop another 20 or so before the end of March. I plan to be under 200lbs by June, and well on my way.
@@momohbanya2296 Yes, I ate at noon on Monday, Tuesday, and Wednesday. It would be three large meals in a 48 hour period, then my next meal was the following Monday. I spend my winters volunteering in Brazil, so I didn't have the fast paced work of a construction site, or the bitter cold of the Canadian winter, which requires burning extra calories. The conditions were supreme, and I just stayed busy during the day to keep my mind focused.
@@momohbanya2296 Yes, I just didn't allow for any second-guessing to enter my mind. So every Monday I would break the fast at noon, and every Wednesday I had my last meal at noon. I made sure to take a half teaspoon of salt every morning, just licked it off my palm, haha, and chugged some water. I had no problems with food cravings, no problems with energy levels, and as long as I kept busy, even with simple tasks, I was able to maintain a pretty joyful experience.
I one time water fasting for 10 days I don't pop for 10 days. Hahaha because I reached my goal weight I was so happy thank you Dr. Fung that was 2 years ago I now happy and healthy size 4.
Just ordered my lovely new coffee mug of yours. A constant reminder each morning not to give in! Plus after 3 wks my weight finally went down 1.5lb! I've found I'm getting less hungry now. I start to feel sick when I need a poop. (Sorry!). I found having an avacado n banana smoothie helps me be more regular. Nuts can cause constipation. Thank fully I'm on no medication, age 59. Been veggie/vegan majority of last 35 yrs. If I crave meat, I'll have some.
🎯 Key Takeaways for quick navigation: 00:14 🤕 *Headaches and dizziness can occur when starting fasting due to potential dehydration from decreased insulin levels. Salt intake or products like pickle juice may help alleviate these symptoms.* 01:53 💩 *Constipation is common in fasting due to reduced food intake. It's normal for bowel movements to decrease; bulking agents like psyllium husk or reducing magnesium intake can aid.* 04:22 🩸 *Blood glucose levels might drop if fasting, especially for those on medications like insulin. Conversely, glucose levels may rise when the body releases stored glucose during fasting, which is normal.* 06:23 😴 *Insomnia can occur due to increased energy from counter-regulatory hormones during fasting. Prioritizing good sleep hygiene and relaxation techniques might help alleviate this issue.* 07:31 🔥 *Acid reflux or heartburn might worsen during fasting, especially in overweight individuals. Strategies like using mild acids, antacids, adjusting sleeping positions, or shorter fasting periods could help manage this.*
I have been doing intermittent fasting for over a year, the least is 16 hours, but I will do 17, 18 and 19 hours, no issues as mentioned. I did my annual checkup with the lab taking blood today, and the nurse asked if I fasted, I said yes, she said how long, I replied 19 hours, she then said why so long, dont you get headaches. I told her it is healthy to fast, she thinks it is crazy fasting.
I just started doing the intermittent fasting 12 to 14 hours this year 😢2/24 coz I was frustrated with my test results of my blood work non fasting, my cholesterol is high n my sugar is high n my doctor diagnosed me with type 2 diabetes, let’s see after 6 months, though I exercise intensely 3 days a week coz am still working but I cut sweat/snacks in between meals, trying to listen your tube blogs all the time to understand what it is going on with my body 😢I believe it will make me better, thanks Dr Jason Fung🙏🏾
Thank you so much young man for this vid. This is day 3 for me of IF and I haven't been to the toilet yet but I shall persevere. Everthing was so we'll explained, and most importantly you offered natural remedies. I've just watched 4 other videos prior to yours and all they want to offer as solutions are man-made digestive enzymes and the like. So thank you for suggesting these simple homemade remedies. It's much appreciated. 👍
Thank you Dr. Fung, fasting has helped improve my health tremendously not to mention losing weight. I’ve tried all of your suggestions here and they work well!✨
Thank you so much, Dr. Fong. I hope you know how amazing and amazing that you are and all that you do to help everyone including me. You've helped me so much thank you I hope you see these messages.
IF, thanks to Fungster has been my normal life for five years. Added with working out my body is better than when in my twenties and thirties. You the man FUNGSTER👍👌💯
@@Intuitivelygifted Yes, its better to start IF slowly, start of with 12 hour and then work you way up. Once you passed the hunger stage (ghrelin) you don't feel hunger anymore. 😊 And oh btw listen to your body and act accordingly
Your body senses a threat and conserves energy. I turn up the heat if I feel cold (and I usually keep the house and office in "conservation" mode, but not on a fast.)
Thanks for your help to understand all processes of prolonged fasting. I just resolved my headache very fast with littlebit of salt, vinegar and water.
My main concerns are headaches insomnia and constipation as I’m posting this at 4 am and woke up at 1:45 am I really hate I can’t sleep and get exhausted during work when I know I’m not allowed to sleep
I've been having a fasting lifestyle for around 3 yrs now. And last night i took magnesium on an empty stomach thinking that might be helpful. But unfortunately that made me have diarrhoea today 😅. So don't try it with magnesium 😂😂😂 otherwise it's the best healing tool ever! Thanks Dr Fung for saving us! 😊😊
The stages of fasting are so interesting!! From headaches to irritability in the first 18-24hrs, then at the 36hr mark the energy!! I never cleaned my house so well, woke up early and scrubbed the oven, fridge, etc. Then nausea kicks in after 48, and that's it for me, but the energy remains. I wake up at 6:30-7am fully rested and completely alert.
Hi Jason, I'm a big fan of your work. Is it true that whey protein in bad for fatty liver? There is so much noise in the internet regarding this. I need an answer from someone like you
Thanks a lot Sir for making this video. I am facing 4 problems which you have discussed. Now I came to know that these problems are normal and will go over a period of time. 🙏
One of the wonderful changes with fasting for me has been feeling a little cooler. I am always hot which indicates my sugar is high. When I fast for over 12 hours, I can feel that my sugar is much better.
I spend every other week out of town with work and do 48 hour fasts during that time. I've had great results with weight loss! However, I've noticed over the last couple months that within an hour of breaking my fast, I have to rush to the bathroom and have at least a large BM, often very watery. My theory is that the mass of the recent meal is somehow pressuring the colon to empty. With that fasting pattern, I usually go 2 days without a BM until the next meal. In about a year, I've lost 80 lbs!
I found my self craving pickle juice at the beginning of my hard core omad fasting. I always wondered what was happening to me, but I just went with what my body asked for and drank the pickle juice 😂 this video just connected some dots. Thanks Dr. 🌻
I can't find any information on your channel or others about nausea around the 48hr mark and afterwards (no heartburn at all, just insane nausea leading to vomiting regardless how much water I drink or don't drink), and mouth pain when breaking the fast with any food. There are hundreds of people on Reddit complaining about these issues due to prolonged fasts. Why does it happen and how to avoid it? I broke my fast with fruit (which I threw up within minutes due to nausea), then I ate a salad with a bit of soft bread but this caused intense pain on the roof of the mouth. I kept drinking a lot of water and started the next day with a very juicy mango, requires no chewing but my tongue muscles near the throat feel like they're cramping up and it becomes nearly impossible to swallow. I've only felt something similar when I had covid. But I know this isn't covid, this issue was happening before and after covid whenever I break a prolonged fast.
It's a controversial topic. My personal experience was that I had a coronary artery calcium score of "2" (obviously not a five-alarm emergency, but not zero) and now my score is zero. I took the tests three years apart, the first about a year after I started fasting and eating keto. Some people may claim that shedding calcium could even be dangerous, but according to Dr Agatston, the authority on the topic, what's desired is to keep the score from going up. He believes that's a win, and that it reduces your risk of (that type of) heart disease.
Hi Dr. Fung, thanks for promoting IF. I have been on it from the past 3 months and doing my regular exercises. Feel good about that, my blood sugar has reduced and i am getting off medication one by one. Lost more than 5 kgs, dont feel hungry etc., but 15 days back, while walking, felt crippling pain in my leg, thought had sprained my leg or fractured. But, no, nothing of the kind. Apparently my uric acid has gone up and causing the pain as it is crytalizing in the bones othetwise gout. Have increased my water intake and now it is slowly decreasing, but may take time. I wanted to go off IF, but then thought better of it and continued. Can you please throw some light on this issue? There are several videos on RUclips about fasting and uric acid, but wanted your opinion on the same. Thanks.
I've had the follow issues and this is what I think is the root cause and a solution. 1. Headaches, especially in the first two days. I think this is lack of fasting practice and being hooked on sugar. I think my metabolism is not use to fasting and so doesn't properly get stored glucose into my body. Solution: Obviously, get added sugar out of your diet first. This takes about eight weeks. Next: work your way up to fasting more than 24 hours. With practice these issues go away or are greatly reduced. I almost never have fasting headaches any more or even hunger that lasts more than 30 minutes. 2. Low blood pressure when on BP meds. After 2-3 days of fasting my BP meds can drop my BP lower, quicker than usual because I am taking them on an empty stomach and my body is not use to having low (i.e. closer to normal!) BP. My heart rate also goes up, which makes me anxious. Solution: just take it easy the first couple of hours after you take your BP meds. At some point, you have to stop taking them I suppose. YEH! 3. Start to get weak and dizzy after 4-5 days of fasting. I think this is due to Insulin Resistance. My BG is lower than my "normal" 12 hour fasting level, but still plenty high enough for a healthy body. But because of Insulin Resistance my body isn't taking the glucose up any more. Solution: I haven't found one yet. I am concerned about pushing past this weakness without a doctor monitoring me. I am hoping that repeating 4 day fasts I will slowly get rid of my insulin resistance and then I can try fasting more than 5 days. It is a bit of a goal for me, not for any health reasons, but having a fasting BG below 70 and being able to fast more than 5 days is a sign that my metabolism and insulin resistance is back to a healthy range. If I'm full of BS, please correct me Dr. Fung. Following your advise is literally saving my life.
An observation about fasting: You still have to be careful about what you eat. Even though I fasted throughout this past holiday season I gained back 10 lbs of the 14 lbs I'd lost and am still having a hard time getting it back off. It's quite discouraging.
❤Hi Dr Fung. I love you, your videos & all the knowledge you share! I need a little more help with exactly what to eat/drink for full nutrition on OMAD & how to safely do a 3-5-14 day or more fast to heal from disease? How do I get an appointment with you??? Thank you so very much! ♥️

Some may want/need to watch more of his videos before you fast. It all depends on how strict you want to be on a fast. I still have my one cup of morning coffee when fasting. I don’t get all crazy about it. That’s just me though and yes, I’ve lost weight
Same here - not having my tea and coffees in the morning, with milk, is a deal breaker for me! I think I've lost a little weight - I don't dare weigh myself as that would REALLY get me depressed - but I do feel better when I do 16/8 so it's worth persevering! I hope I lose weight as you have - that would be WONDERFUL!!
@@andersonomo597 , 100% same. Coffe, tea, even bullet proof coffe is a go, as long as it helps to keep going through the hours. And I have the same relationship with scale - after all the work I put in working out, building muscle, eating healthy, and now fasting, when the scale doesn’t budge at all it’s very depressing and all I want to do is to throw tge towel. But then i realize how loose my pants feel and good I feel and i just tell myself that it’s worth it! The scale and my body just are playing this joke on me like saying: you won’t see your weight drop no matter how stubborn you are - we win! The only time i get my weight is when i go for my physical- and i hate stepping on the scale then cause I already know :))
@@ilonaghine9690 I've just listened to 2 REALLY interesting interviews on "The Diary of a CEO " featuring Dr Tim Spector and Dr Giles Yeo. There's so much info there about calories and blood sugar spikes and how different foods affect people differently. Highly recommend listening to both - there's nothing 'visual' in either interview so you can easily listen while doing other things. Both interviews have made me re-think how I'm eating - I'll focus more on high fiber foods, more vegetable varieties and not no-carbs but fewer carbs. Cost = ZERO, benefits = can't hurt, worth trying!! And yes, the joy of looser pants, for me that's important, not the number which will send me into a deep funk!! Best wishes for success in your efforts!!
@@andersonomo597 , thank you! Will definitely check out the interviews! Always eager to learn and improve my health. Take care,
It's a good point about coffee. If you're a coffee drinker and go cold turkey, _that_ can give you a "caffeine headache."
Yep! I remember having some of those problems. It's so true that your body adjusts! Thanks Dr. Fung for all you do 😊👍
Jason jumped on your bus and rang your bell and shared you on my community tab
Very helpful. I didn’t attribute my insomnia and feeling wide awake and energized to fasting. Good to know.
The salt definitely helps the headaches. And for me it works instantly- the headache goes away in 5 min after I add a Hymalayan salt to my water. Thank you, Dr.Fung!
I have been experiencing headaches too when doing intermittent fasting. Will definitely try salt.
Salt helps us retain a healthy amount of water. If we don't have enough, we can get severely dehydrated and our brain literally shrinks, causing negative pressure.
PS: In this way, it is similar to caffeine, in which going cold turkey may cause a change in brain pressure that results in headaches.
@@CarbageMan , thank you for explaining the effect. I wasn’t sure why it helped but when i got the headaches I was like let’s give it a try and amazingly it worked. Also, i tend to drink lots of coffee and I just saw it from someone’s post that coffee during fast can cause headaches more severely than if you just drink water.
@@ilonaghine9690 You bet! I found myself more comfortable drinking the same amount of caffeine as I'm used to.
Yes, acid stomach has been my main complaint during IF. It's good to know I'm not crazy.
Try Apple cider vinegar, a couple of Tablespoons in some water twice a day. It seems counter intuitive, but I have full blown GERD Gastric Reflux disease. And doing it for a few months actually cured my disease. So give it a try, you can thank me later!
It was the reason I had to stop my fast. I couldn't get rid of it without eating something. So painful.
@@JoB888 My doctor had me start on OTC Famotidine (Pepcid AC). It's helped immensely.
SAME HERE!
Sir I have been doing 18:06 hours of fasting every day that 6 hours of food window and 18 hours of water fasting and I have been doing it’s from past 12 months and I have doing good gym workout at gym “ hope I m
Doing well intermittent fasting “ as I m feeling very good 👍🏻
Wonderful thanks...I am having trouble with dizziness when I've gone up to a 48 hour fast so I'll try drinking more water and take a bit of salt.
we shall not live on bread alone!! you are awesome!
*But, You Must Learn now, to Live upon the words of My Lord GOD, DonaLd Trump, ALONE!!!!*
I have read your book. You changed my life.
Thank you so much for this Dr. Fung.
Just started a 5 day water fast!
*My GOD, DonaLd Trump, was Sent by GOD to SAVE the Earth!!! Dec.24, 2024*
Some video's on RUclips are quite good. Others are good enough to be public service announcement. Thank you much.
The best adjustment that I made was instead of adding salt and potassium to my water, I just take a 3/4 teaspoon of pink salt in the morning and/or evening. I found that the chalky taste of water after three days would make any further fasting a big challenge. By taking the salt directly, I can continue drinking fresh water all day without the hesitation to stay hydrated. I can do five day fasts without batting an eye. I dropped 30lbs in five weeks at the end of last year. I've just initiated a four week regiment. I should drop another 20 or so before the end of March. I plan to be under 200lbs by June, and well on my way.
Thats awesome. You did 5 day fast every week for 5 weeks? Did you eat the other two days each week?
@@momohbanya2296 Yes, I ate at noon on Monday, Tuesday, and Wednesday. It would be three large meals in a 48 hour period, then my next meal was the following Monday. I spend my winters volunteering in Brazil, so I didn't have the fast paced work of a construction site, or the bitter cold of the Canadian winter, which requires burning extra calories. The conditions were supreme, and I just stayed busy during the day to keep my mind focused.
@@momohbanya2296 Yes, I just didn't allow for any second-guessing to enter my mind. So every Monday I would break the fast at noon, and every Wednesday I had my last meal at noon. I made sure to take a half teaspoon of salt every morning, just licked it off my palm, haha, and chugged some water. I had no problems with food cravings, no problems with energy levels, and as long as I kept busy, even with simple tasks, I was able to maintain a pretty joyful experience.
Congratulations
I always wait for your new videos very desperately. Thank you, Dr. jason fung.
Desperately ? lol
Thank you Dr Jason, I understand more today. Blessings to everyone! Thank you indeed.
Thanks!
I one time water fasting for 10 days I don't pop for 10 days. Hahaha because I reached my goal weight I was so happy thank you Dr. Fung that was 2 years ago I now happy and healthy size 4.
Just ordered my lovely new coffee mug of yours. A constant reminder each morning not to give in! Plus after 3 wks my weight finally went down 1.5lb! I've found I'm getting less hungry now. I start to feel sick when I need a poop. (Sorry!). I found having an avacado n banana smoothie helps me be more regular. Nuts can cause constipation. Thank fully I'm on no medication, age 59. Been veggie/vegan majority of last 35 yrs. If I crave meat, I'll have some.
It now makes more sense about diarrhea, thanks Dr Fung.
🎯 Key Takeaways for quick navigation:
00:14 🤕 *Headaches and dizziness can occur when starting fasting due to potential dehydration from decreased insulin levels. Salt intake or products like pickle juice may help alleviate these symptoms.*
01:53 💩 *Constipation is common in fasting due to reduced food intake. It's normal for bowel movements to decrease; bulking agents like psyllium husk or reducing magnesium intake can aid.*
04:22 🩸 *Blood glucose levels might drop if fasting, especially for those on medications like insulin. Conversely, glucose levels may rise when the body releases stored glucose during fasting, which is normal.*
06:23 😴 *Insomnia can occur due to increased energy from counter-regulatory hormones during fasting. Prioritizing good sleep hygiene and relaxation techniques might help alleviate this issue.*
07:31 🔥 *Acid reflux or heartburn might worsen during fasting, especially in overweight individuals. Strategies like using mild acids, antacids, adjusting sleeping positions, or shorter fasting periods could help manage this.*
Thank you, Doctor!
Thanks Doc, J. Fung for helping us. 💖
Wow. Very enlightening. Thank you
I have been doing intermittent fasting for over a year, the least is 16 hours, but I will do 17, 18 and 19 hours, no issues as mentioned. I did my annual checkup with the lab taking blood today, and the nurse asked if I fasted, I said yes, she said how long, I replied 19 hours, she then said why so long, dont you get headaches. I told her it is healthy to fast, she thinks it is crazy fasting.
I just started doing the intermittent fasting 12 to 14 hours this year 😢2/24 coz I was frustrated with my test results of my blood work non fasting, my cholesterol is high n my sugar is high n my doctor diagnosed me with type 2 diabetes, let’s see after 6 months, though I exercise intensely 3 days a week coz am still working but I cut sweat/snacks in between meals, trying to listen your tube blogs all the time to understand what it is going on with my body 😢I believe it will make me better, thanks Dr Jason Fung🙏🏾
16 to 18 hours fasting will give you good results
I've been having an elevated blood sugar in the morning. It's been are 130 for quite some time. Today it was 113 so making progresd.
Fasting today and tomorrow....
I enjoyed and learned such with your fasting book!!!
Excellent book!
Thank you so much young man for this vid. This is day 3 for me of IF and I haven't been to the toilet yet but I shall persevere. Everthing was so we'll explained, and most importantly you offered natural remedies. I've just watched 4 other videos prior to yours and all they want to offer as solutions are man-made digestive enzymes and the like. So thank you for suggesting these simple homemade remedies. It's much appreciated. 👍
Thank you Dr. Fung, fasting has helped improve my health tremendously not to mention losing weight. I’ve tried all of your suggestions here and they work well!✨
Thank you so much, Dr. Fong. I hope you know how amazing and amazing that you are and all that you do to help everyone including me. You've helped me so much thank you I hope you see these messages.
Thanks, Dr. Fung.
Thank you for the good info
Thanks so much Dr Fung. Can you please make a video explaining how long and often people in different age groups should do fasting to lose fat? 🙏
Mr Jason , you are so helpful , thank you for your videos
the problem using magnesium supplement only occurs if you use a cheep one with magnesium oxide and not citrate based magnesium
Love your videos Dr Fung! Thank you.
IF, thanks to Fungster has been my normal life for five years.
Added with working out my body is better than when in my twenties and thirties.
You the man FUNGSTER👍👌💯
Hey there that’s great! Do you still get hungry or did the hunger go away?
@@Intuitivelygifted
Yes, its better to start IF slowly, start of with 12 hour and then work you way up.
Once you passed the hunger stage (ghrelin) you don't feel hunger anymore. 😊
And oh btw listen to your body and act accordingly
Thank you Doc!
Thanks a lot, i was worried about not going to the toilet. I don't get constipated nor feel uncomfortable just go after 2nd day.
My only symptom is episodes of extreme cold. No amount of warm liquids or blankets help. Why please?
stress causes vasoconstriction and that pulls blood away from extremities
Your body senses a threat and conserves energy. I turn up the heat if I feel cold (and I usually keep the house and office in "conservation" mode, but not on a fast.)
🙏🏽🙏🏽🙏🏽Dr Fung
Thankyou this helps greatly .
Thanks Dr. Fung. You have helped me so much.
Thanks for your help to understand all processes of prolonged fasting. I just resolved my headache very fast with littlebit of salt, vinegar and water.
My main concerns are headaches insomnia and constipation as I’m posting this at 4 am and woke up at 1:45 am I really hate I can’t sleep and get exhausted during work when I know I’m not allowed to sleep
I put my salt on a teaspoon and dab on my tongue, letting it dissolve a little at a time. Then I drink water. Much easier than drinking salt water.
What kind of salt?
@@mjxx6723 I use Celtic Sea Salt.
I prefer this, too. I use Smoked Redmond Real Salt. It's tasty and has no additional nutrients.
@@mjxx6723 Some use Himalayan salt.
Nice video.Thanks.
Thank you for the video Mr fung your amazing I been doing vegan intermittent fasting for fee years now love intermittent fasting
Please do a video on this new peptide PEPITEM. I value your opinion Dr Jason.
hi
I've been having a fasting lifestyle for around 3 yrs now. And last night i took magnesium on an empty stomach thinking that might be helpful. But unfortunately that made me have diarrhoea today 😅. So don't try it with magnesium 😂😂😂 otherwise it's the best healing tool ever! Thanks Dr Fung for saving us! 😊😊
At 36hrs + is hard to sleep! 😂😅 I LOVE IT! Full on energy! ❤
The stages of fasting are so interesting!! From headaches to irritability in the first 18-24hrs, then at the 36hr mark the energy!! I never cleaned my house so well, woke up early and scrubbed the oven, fridge, etc. Then nausea kicks in after 48, and that's it for me, but the energy remains. I wake up at 6:30-7am fully rested and completely alert.
Love his videos. Thanks doc!
Very helpful, as always. Thank you.
Hi Jason, I'm a big fan of your work. Is it true that whey protein in bad for fatty liver? There is so much noise in the internet regarding this. I need an answer from someone like you
he is for protein unless in serious levels of kidney failure.
Thanks a lot Sir for making this video. I am facing 4 problems which you have discussed. Now I came to know that these problems are normal and will go over a period of time. 🙏
You are awesome! Thank you Dr Fung!
One of the wonderful changes with fasting for me has been feeling a little cooler. I am always hot which indicates my sugar is high. When I fast for over 12 hours, I can feel that my sugar is much better.
I spend every other week out of town with work and do 48 hour fasts during that time. I've had great results with weight loss! However, I've noticed over the last couple months that within an hour of breaking my fast, I have to rush to the bathroom and have at least a large BM, often very watery. My theory is that the mass of the recent meal is somehow pressuring the colon to empty. With that fasting pattern, I usually go 2 days without a BM until the next meal. In about a year, I've lost 80 lbs!
I found my self craving pickle juice at the beginning of my hard core omad fasting. I always wondered what was happening to me, but I just went with what my body asked for and drank the pickle juice 😂 this video just connected some dots. Thanks Dr. 🌻
Aren’t the “spikes” that are dangerous? Then why high glucose reading in the morning doesn't matter?
Excellent video, especially explaining the glucose in your system. Thank you!
Yes,the best ! I'm using freestyle sensor to check the fluctuations of insulin, is unbelievable how our body using the resources
Thank you!
I can't find any information on your channel or others about nausea around the 48hr mark and afterwards (no heartburn at all, just insane nausea leading to vomiting regardless how much water I drink or don't drink), and mouth pain when breaking the fast with any food. There are hundreds of people on Reddit complaining about these issues due to prolonged fasts. Why does it happen and how to avoid it?
I broke my fast with fruit (which I threw up within minutes due to nausea), then I ate a salad with a bit of soft bread but this caused intense pain on the roof of the mouth. I kept drinking a lot of water and started the next day with a very juicy mango, requires no chewing but my tongue muscles near the throat feel like they're cramping up and it becomes nearly impossible to swallow. I've only felt something similar when I had covid. But I know this isn't covid, this issue was happening before and after covid whenever I break a prolonged fast.
What about metabolism? Does fasting too often/too long decrease metabolism?
Hi Dr. Fung,
What effects does fasting have on atherosclerosis and heart disease? Can it possibly reverse it?
That’s a great question… I’ve wondered the same 🧐
Yes it can reverse, clearing plaque is a catabolic process and eating just makes it worse
It's a controversial topic.
My personal experience was that I had a coronary artery calcium score of "2" (obviously not a five-alarm emergency, but not zero) and now my score is zero. I took the tests three years apart, the first about a year after I started fasting and eating keto.
Some people may claim that shedding calcium could even be dangerous, but according to Dr Agatston, the authority on the topic, what's desired is to keep the score from going up. He believes that's a win, and that it reduces your risk of (that type of) heart disease.
@@LTPottenger whoa
thanks man!
Hi Dr. Fung, thanks for promoting IF. I have been on it from the past 3 months and doing my regular exercises. Feel good about that, my blood sugar has reduced and i am getting off medication one by one. Lost more than 5 kgs, dont feel hungry etc., but 15 days back, while walking, felt crippling pain in my leg, thought had sprained my leg or fractured. But, no, nothing of the kind. Apparently my uric acid has gone up and causing the pain as it is crytalizing in the bones othetwise gout. Have increased my water intake and now it is slowly decreasing, but may take time. I wanted to go off IF, but then thought better of it and continued. Can you please throw some light on this issue? There are several videos on RUclips about fasting and uric acid, but wanted your opinion on the same. Thanks.
Informative
I've had the follow issues and this is what I think is the root cause and a solution.
1. Headaches, especially in the first two days. I think this is lack of fasting practice and being hooked on sugar. I think my metabolism is not use to fasting and so doesn't properly get stored glucose into my body. Solution: Obviously, get added sugar out of your diet first. This takes about eight weeks. Next: work your way up to fasting more than 24 hours. With practice these issues go away or are greatly reduced. I almost never have fasting headaches any more or even hunger that lasts more than 30 minutes.
2. Low blood pressure when on BP meds. After 2-3 days of fasting my BP meds can drop my BP lower, quicker than usual because I am taking them on an empty stomach and my body is not use to having low (i.e. closer to normal!) BP. My heart rate also goes up, which makes me anxious. Solution: just take it easy the first couple of hours after you take your BP meds. At some point, you have to stop taking them I suppose. YEH!
3. Start to get weak and dizzy after 4-5 days of fasting. I think this is due to Insulin Resistance. My BG is lower than my "normal" 12 hour fasting level, but still plenty high enough for a healthy body. But because of Insulin Resistance my body isn't taking the glucose up any more. Solution: I haven't found one yet. I am concerned about pushing past this weakness without a doctor monitoring me. I am hoping that repeating 4 day fasts I will slowly get rid of my insulin resistance and then I can try fasting more than 5 days. It is a bit of a goal for me, not for any health reasons, but having a fasting BG below 70 and being able to fast more than 5 days is a sign that my metabolism and insulin resistance is back to a healthy range.
If I'm full of BS, please correct me Dr. Fung. Following your advise is literally saving my life.
Wonderful
Today I just completed my 36 hours of fasting on the occasion of “valentines day” ❤❤
I'm on day 7 of a water fast and i am extremely quick to fatigue and am very nauseous. I am doing salt in my water.
Thank you 🙏
Started IF 2 weeks ago and I began to experience headaches. But as soon as I drink some salt water, it goes away
Can you eat only two days a week and fast 5 days ?
Thanks
I always take electrolytes when I fast. I last a lot longer then.
An observation about fasting: You still have to be careful about what you eat.
Even though I fasted throughout this past holiday season I gained back 10 lbs of the 14 lbs I'd lost and am still having a hard time getting it back off. It's quite discouraging.
eat real food and lower carbs and you won't have to count calories to stay fit. If you have to work to stay skinny your diet is garbage, end of story.
Great info! Thank you
Doctor Fung, please aknowledge that I know your works since 1 week only and that you are already one if idols
❤Hi Dr Fung. I love you, your videos & all the knowledge you share!
I need a little more help with exactly what to eat/drink for full nutrition on OMAD
& how to safely do a 3-5-14 day or more fast to heal from disease?
How do I get an appointment with you???
Thank you so very much! ♥️
im 14 days in the 20/4 and this last week has been terrible as my blood pressure has been running sky high even on my medication. if it doesnt stablise by next week im gonna have to go to the doctor
If you feel unwell, you should discontinue your fast. Consider a less aggressive fast (like 18/6) next time.
@@CarbageMan had my blood pressure meds adjusted bp back to nomral....the 20/4 continues
@@captrodgers4273 Great!
Glad to finally understand why I am urinating more.
The background is nicer
I've tried IF, but It doesn't work to me at all. I noticed no change of my blood level and I ate even more as before. I still avoid the carbs.
try 36 h fast
36-96 h fasts are foolproof
Practice, practice, practice.
