@@pnair78 I have this question as well. I am on a 38 hour fast, looking to make it to 42 hour, and I am a frequent faster as well. I have been doing it for a few years now. Yesterday I was getting soooo out of breath, and it worried me. I am still having heart palpitations.
@@sharminrahman8038 i went to emergency and a muslim doctor who are well versed in fasting told me to drink enough water and increase the fasting hours periodically and not suddenly. All is good now. Thank God.
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🙏
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?
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!!
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.
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 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
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.
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.
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.
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’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🙏🏻
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!
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.
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.
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!✨
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🙏🏾
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.
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
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 👍🏻
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!
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.
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.
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.
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.
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 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. 🙏
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! 😊😊
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 experienced all these symptoms randomly, especially after a few days on fasting for 20 hours. I always get muscles cramps when fasting 20 hours more than 2 days. I thought that's something to do with my old age. Am 70
Yeah it’s so weird, every single “diet” I tried, made me miserable. Constant cravings, intense hunger, dizziness, mood swings, irritability, feeling cold all the time, are just one of many negative experiences I’ve had. And it’s almost impossible to stick to, and when I did find the discipline to stick to it, the weight loss is temporary and will always go back up after. None of the diets were doable for life. I attempted fasting a couple of times, but this is like the 7th time in the past 4 years of me doing intermittent fasting, and my body finally adapted. Now I know it’s not willpower or lack of discipline, because I can eat once or twice a day, never ever feel hungry, almost never have a craving, and the weight comes down automatically. I also feel like I’m beginning to increase physical activity because I feel like moving around more. My dog is happy with that, but so am I. I now have the energy to get out of bed, do some household chores, and feel good by going to bed around 11pm. Waking up isn’t a pain in the ass like it used to and I feel more comfortable being social instead of locking myself inside for 6 days a week. I confirm everything that Jason Fung has said so far, it’s all true, and it all works! I eat less and less, so my stomach is shrinking, my body craves veggies now, and I eat less carbs and more fat than before, I’m happy and I’m anxiously anticipating the results in 6 months from now 🙏🏼
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
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
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.
Three months into IF, 16-22 hours, heavy workout 4 times a week. Haven't lost a pound, I've gained a half. 61 post menopausal woman, NEVER anything about that age, gender. Other than that I love Jason.
Exercise is important for other reasons, but it actually increases my appetite. I'm close in age to you, post menopausal and lost 85 lbs. I maintained 80 of it for a year or so and am now allowing the weight to go down again. However, in addition to TRE (time restricted eating.. or also known as daily intermittent fasting), I also do regular extended fasts. I'm certain that the extended fasts not only helped me lose body fat but also reduce loose skin. (Of course other positives such as pain management etc.) Be kind to yourself. If interested in extended fasts increase your time gradually, eat well when you do eat, and be kind to yourself.
I always say The Lord's Prayer, then I would fall asleep 😊 or fold some clothes from the clothesline before I knew it I'm sleeping already. Thanks doc for all these medical health guidelines, it helps medically 🙂
Hi Nancy. I fast regularly both TRE and extended fasts. When I don't welcome weight loss, I eat more often (still not more than 3 times a day), eat more fats and protein (whole foods of course) and also exercise. Exercise builds my appetite helping me to eat more than I might otherwise.
Headache, dizziness, dehydration. Constipation, insomnia, acid reflux, are very basic symptoms. And most people can deal with them . But other symptoms such as pounding and racing heart, high BP and blurry vision are very scary symptoms. I believe probably for women. It scared the hell out of me. End up in ER 2 times. It started with fasting. Taking Salt etc didn’t help at all. Can you please elaborate on these major symptoms .I gave up my fasting because of those symptoms. Thank you
You and me! I'm mostly carnivore keto and always feel like 💩. It's been 7 months. Exhausted, headaches more like brain not working. My BP is low. I get blurry vision. No one addresses these side effects. I'm glad I'm not the only one! I even add 2000g of sodium with potassium and drink water. Soooo. 😢 what's wrong with us that makes us outliers?
@@jenjabba6210finally I’m able to control some of these symptoms with celtic salt each time I pee I drink water with some Celtic salt crystals. It took few months. Also taking potassium and magnesium. Now only problem I have my sugar is going high with fasting and not losing weight. But I can fast now up to 30 hrs . I think probably also our cortisol goes up during fasting that cause these symptoms. Still trying to balance my cortisol. Breathing walking is not helping. Looking for supplements. Also dr Mindys book and her channel helped me with some symptoms and understanding it.
@@elizabethkoenig5185 Hi. I figured it out. The culprit was the avocado. I cut that out and now have no trouble doing 16/8 fasting. Too bad; I rather like avocado.
Hi Doctor, I am following your videos for more than a year. Now I am doing 16 hours fasting everyday and 8 hours eating. I lose 12 lbs. and my BMI is 24, I am 63 years old. No metabolic syndrome. I have Valvular disease ( Mitral and Arotic valve insufficiency - Moderate to mild). Can you make video on the valvular disease ? Is this valvular heart disease is reversible?
❤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! ♥️
Have done a video on how fasting is different if you do not have a gallbladder? If not can you? I experience a sour gut off and on during fasting and horrible diarrhea when I start eating again.
Fasting has triggered hyperthyroidism, even though I do not have a thyroid gland due to receiving radio-iodine some years ago. Since I no longer have a family physician, I am finding it pretty difficult to manage and have to rely on walk-in clinics for help, which isn't actually helpful...other than that, I feel great, without symptoms named in the video.
Hi Dr Fung, today is day 1 attempting OMAD. I had 2 cups of cuppacino for breakfast and skipped lunch. By around 730pm, i measured my ketones and blood glucose using keto-mojo device. The measurements are 0.6 mmol/L and 67 mg/dL respectively. The word hypo (representing hypoglycemia) flashes on the display. I felt a little hungry, other than that i felt fine. What do i make out of it? I'm petite at 5' 1" and weigh 57kg, I'm plump (jiggly fat around torso, thigh and underarm), i am not diabetic. Just a regular person looking to lose some weight to be healthier and have more energy. I'm constantly tired and lethargic.
I would wonder about that cappuccino. It has cream, right? That means it's not a "clean" fast. After a year of IF (-45lbs, reversed T2D), I have learned that fasting for me means water and black tea only.
You don't need to sleep when you fast, you are not doing anabolic healing but catabolic healing. But red light therapy on the head will make almost anyone sleep
I too also have difficulty in sleeping when fasting with just water since I switch to fasting for 24 and eat whatever I like I started having my sleep back mind you those time I wasn't sleeping my scale was just same numbers for days and I watched dr j video when a lady said if your scale is not giving what you want you either take a video or picture of yourself, that has been working for me I can't afford to be discourage by my scale
It's my understanding that the stomach isn't producing acid all of the time, only when eating. I believe this is the reason we're told to eat something small before taking a medication that upsets the stomach... that when you eat, the stomach secretes mucus to protect itself from the acid that will follow, hence, the acid isn't always there. Why is the stomach secreting acid when it's empty? Reflux is wrecking me during my fasts (3.5 days a week) and nothing is helping, including everything you mentioned... and Betaine supplements too.
Acid goes down when you fast, but if you have reflux then it may need help to control it at first while fasting, such as taking potassium bicarbonate (use a straw, bad for teeth).

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.

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!
Best comment.
This show us human the Greatness of Allah the creator of everything.
There is no God except Allah.
Even healthy bodyweight people have enough fat on them to last for over a month without food.
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!
His explanation about insulin resistance helped me a lot. I rejoice that my body is releasing stored fat!
@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?
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."
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.
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.
Ever since I started Fasting I Can Sleep 7 hours . 🤗 And I'm loosing weight I feel health for once in my life .
thats great
Yep! I remember having some of those problems. It's so true that your body adjusts! Thanks Dr. Fung for all you do 😊👍
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
Do you use a cgm or finger jab to track blood glucose levels after eating lots of vegetables?
I agree
Could try only meat? It is great! Keeps you full wayy longer
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.
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.
When I can’t sleep because of fasting I read the Bible or any book and clean my house that works for me always
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.
Amen
I also read my Bible. Be blessed.
we shall not live on bread alone!! you are awesome!
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’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🙏🏻
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!
Very helpful. I didn’t attribute my insomnia and feeling wide awake and energized to fasting. Good to know.
Just started a 5 day water fast!
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.
I have read your book. You changed my life.
It now makes more sense about diarrhea, thanks Dr Fung.
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
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!✨
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🙏🏾
Some video's on UA-cam are quite good. Others are good enough to be public service announcement. Thank you much.
Fasting today and tomorrow....
I enjoyed and learned such with your fasting book!!!
Excellent book!
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.
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 always wait for your new videos very desperately. Thank you, Dr. jason fung.
Desperately ? lol
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
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 👍🏻
Thank you Dr Jason, I understand more today. Blessings to everyone! Thank you indeed.
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.
Jason jumped on your bus and rang your bell and shared you on my community tab
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!
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.
Today I just completed my 36 hours of fasting on the occasion of “valentines day” ❤❤
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. 🌻
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? 🙏
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.
Thanks Doc, J. Fung for helping us. 💖
Thank you so much for this Dr. Fung.
Thank you for the video Mr fung your amazing I been doing vegan intermittent fasting for fee years now love intermittent fasting
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.
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.
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.
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.
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. 🙏
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.
Thank you, Doctor!
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! 😊😊
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.)
the problem using magnesium supplement only occurs if you use a cheep one with magnesium oxide and not citrate based magnesium
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 experienced all these symptoms randomly, especially after a few days on fasting for 20 hours. I always get muscles cramps when fasting 20 hours more than 2 days. I thought that's something to do with my old age. Am 70
I used to get cramps--not fasting, just in in general. Taking magnesium, calcium, and potassium solved this issue.
Yeah it’s so weird, every single “diet” I tried, made me miserable. Constant cravings, intense hunger, dizziness, mood swings, irritability, feeling cold all the time, are just one of many negative experiences I’ve had. And it’s almost impossible to stick to, and when I did find the discipline to stick to it, the weight loss is temporary and will always go back up after. None of the diets were doable for life. I attempted fasting a couple of times, but this is like the 7th time in the past 4 years of me doing intermittent fasting, and my body finally adapted. Now I know it’s not willpower or lack of discipline, because I can eat once or twice a day, never ever feel hungry, almost never have a craving, and the weight comes down automatically. I also feel like I’m beginning to increase physical activity because I feel like moving around more. My dog is happy with that, but so am I. I now have the energy to get out of bed, do some household chores, and feel good by going to bed around 11pm. Waking up isn’t a pain in the ass like it used to and I feel more comfortable being social instead of locking myself inside for 6 days a week. I confirm everything that Jason Fung has said so far, it’s all true, and it all works! I eat less and less, so my stomach is shrinking, my body craves veggies now, and I eat less carbs and more fat than before, I’m happy and I’m anxiously anticipating the results in 6 months from now 🙏🏼
Without fail for me, diarrhea will happen if I am occasionally stressed or excited about something in my life. It's psychological here.
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 Dr. Fung. You have helped me so much.
Doctor Fung, please aknowledge that I know your works since 1 week only and that you are already one if idols
Listening to Alan Watts can help with sleep. Not because he is boring, but because his voice is sooooo, soothing.
Aren’t the “spikes” that are dangerous? Then why high glucose reading in the morning doesn't matter?
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.

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
Please do a video on this new peptide PEPITEM. I value your opinion Dr Jason.
What about metabolism? Does fasting too often/too long decrease metabolism?
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
Three months into IF, 16-22 hours, heavy workout 4 times a week. Haven't lost a pound, I've gained a half. 61 post menopausal woman, NEVER anything about that age, gender. Other than that I love Jason.
It works even better for older women and that is most of his patients. daily IF won't lose weight any better than dieting you need 36-96
Exercise is important for other reasons, but it actually increases my appetite. I'm close in age to you, post menopausal and lost 85 lbs. I maintained 80 of it for a year or so and am now allowing the weight to go down again. However, in addition to TRE (time restricted eating.. or also known as daily intermittent fasting), I also do regular extended fasts. I'm certain that the extended fasts not only helped me lose body fat but also reduce loose skin. (Of course other positives such as pain management etc.)
Be kind to yourself. If interested in extended fasts increase your time gradually, eat well when you do eat, and be kind to yourself.
@@AzaleaBee Thank you! Yeah, being kind to myself is important!
Like me, you may need to up your fasting, I never lost any weight before going to ADF.

Wow. Very enlightening. Thank you
What if your bmi is good and you want to fast for health benefits. Please make a video on people that don’t want to lose weight.
You usually gain lean tissue from short fasts
Hi Nancy. I fast regularly both TRE and extended fasts. When I don't welcome weight loss, I eat more often (still not more than 3 times a day), eat more fats and protein (whole foods of course) and also exercise. Exercise builds my appetite helping me to eat more than I might otherwise.
Mr Jason , you are so helpful , thank you for your videos
Glad to finally understand why I am urinating more.
Love your videos Dr Fung! 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
Headache, dizziness, dehydration. Constipation, insomnia, acid reflux, are very basic symptoms. And most people can deal with them . But other symptoms such as pounding and racing heart, high BP and blurry vision are very scary symptoms. I believe probably for women. It scared the hell out of me. End up in ER 2 times. It started with fasting. Taking Salt etc didn’t help at all. Can you please elaborate on these major symptoms .I gave up my fasting because of those symptoms. Thank you
You and me! I'm mostly carnivore keto and always feel like 💩. It's been 7 months. Exhausted, headaches more like brain not working. My BP is low. I get blurry vision. No one addresses these side effects. I'm glad I'm not the only one! I even add 2000g of sodium with potassium and drink water. Soooo. 😢 what's wrong with us that makes us outliers?
@@jenjabba6210finally I’m able to control some of these symptoms with celtic salt each time I pee I drink water with some Celtic salt crystals. It took few months. Also taking potassium and magnesium. Now only problem I have my sugar is going high with fasting and not losing weight. But I can fast now up to 30 hrs . I think probably also our cortisol goes up during fasting that cause these symptoms. Still trying to balance my cortisol. Breathing walking is not helping. Looking for supplements. Also dr Mindys book and her channel helped me with some symptoms and understanding it.
Definitely having issues with rather hurried dashes to the bathroom, about two hours after breaking my fast. It's a bit inconvenient to say the least.
Do you eat enough fiber?
@@elizabethkoenig5185 Hi. I figured it out. The culprit was the avocado. I cut that out and now have no trouble doing 16/8 fasting. Too bad; I rather like avocado.

I am following your videos for more than a year. Now I am doing 16 hours fasting everyday and 8 hours eating. I lose 12 lbs. and my BMI is 24, I am 63 years old. No metabolic syndrome. I have Valvular disease ( Mitral and Arotic valve insufficiency - Moderate to mild). Can you make video on the valvular disease ? Is this valvular heart disease is reversible?
❤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! ♥️
Thank you for the good info
Have done a video on how fasting is different if you do not have a gallbladder? If not can you? I experience a sour gut off and on during fasting and horrible diarrhea when I start eating again.
Question -: Can fasting bring on depression/low mood especially at morning . Any data on this even for an experienced faster ? Thanks
I definitely experienced that, too. There could be a connection, i`m in my first week maybe it goes away after a while
Fasting has triggered hyperthyroidism, even though I do not have a thyroid gland due to receiving radio-iodine some years ago. Since I no longer have a family physician, I am finding it pretty difficult to manage and have to rely on walk-in clinics for help, which isn't actually helpful...other than that, I feel great, without symptoms named in the video.
You don't have hyperthyroidism with no gland. You might have higher adrenaline
Hi Dr Fung, today is day 1 attempting OMAD. I had 2 cups of cuppacino for breakfast and skipped lunch. By around 730pm, i measured my ketones and blood glucose using keto-mojo device. The measurements are 0.6 mmol/L and 67 mg/dL respectively. The word hypo (representing hypoglycemia) flashes on the display. I felt a little hungry, other than that i felt fine. What do i make out of it? I'm petite at 5' 1" and weigh 57kg, I'm plump (jiggly fat around torso, thigh and underarm), i am not diabetic. Just a regular person looking to lose some weight to be healthier and have more energy. I'm constantly tired and lethargic.
After you ate carbs earlier. All hypoglycemia is reactive except for some very rare forms of tumors. Do some longer fasts and reduce your carbs.
I would wonder about that cappuccino. It has cream, right? That means it's not a "clean" fast. After a year of IF (-45lbs, reversed T2D), I have learned that fasting for me means water and black tea only.
Solution to Insomnia: Quote: “There’s nothing to do about that”. Good. At least you’re honest. That’s why fasting doesn’t work for me. I CAN’T SLEEP✅
You don't need to sleep when you fast, you are not doing anabolic healing but catabolic healing. But red light therapy on the head will make almost anyone sleep
I’ve slept fantastic since fasting and lost 13 kgs. Pity you can’t sleep, especially if you want to lose weight.
I do much better if I use a castor oil pack over liver, may be worth trying.
I too also have difficulty in sleeping when fasting with just water since I switch to fasting for 24 and eat whatever I like I started having my sleep back mind you those time I wasn't sleeping my scale was just same numbers for days and I watched dr j video when a lady said if your scale is not giving what you want you either take a video or picture of yourself, that has been working for me I can't afford to be discourage by my scale
@@kkakuszi5423 why? We’re you hungry?
Love his videos. Thanks doc!
It's my understanding that the stomach isn't producing acid all of the time, only when eating. I believe this is the reason we're told to eat something small before taking a medication that upsets the stomach... that when you eat, the stomach secretes mucus to protect itself from the acid that will follow, hence, the acid isn't always there.
Why is the stomach secreting acid when it's empty? Reflux is wrecking me during my fasts (3.5 days a week) and nothing is helping, including everything you mentioned... and Betaine supplements too.
Acid goes down when you fast, but if you have reflux then it may need help to control it at first while fasting, such as taking potassium bicarbonate (use a straw, bad for teeth).
