Dr. Fung changed my life. I was diagnosed with Type-2 Diabetes a few years ago and was put on medication. Years later, I discovered Dr. Fung and this idea of IF. After 8 months of IF, weight training and a low carb diet, I’ve lost over 40lbs and lowered my A1C from over 11 to 5.7. At this point in time, I no longer need medication. I still need to lose another 15 or so pounds to be at my ideal weight but I am on the right path. Thank You!

@AJDOLDCHANNELARCHIVE 2 года назад

So cool to hear the car engine longevity analogy from someone other than me haha... I came up with that when I was about 15 years old (15 years ago) as I realised I had a very low metabolic rate/caloric requirement (and can build muscle very easily with little training and little protein, IE; 50-70g a day max and sub 2,000 calories). Since I was that age I was always saying I was going to live to 200, I completely quit sugar or any synthetic compounds around then, and have since done dozens of long terms fasts, including 7 day dry fasts. Now I just do a 7 day water fast at the end of every month, only eat 1 meal a day when not fasting, try to do low carb apart from my somewhat excessive beer intake haha... Haven't been ill once since then, so half of my life. Back to the engine analogy, I always likened it to the difference between a low revving V8 engine that could last 100,000 miles without a rebuild compared to a 10,000+ RPM race car that can complete but a single race before being completely deteriorated. Cheers from the UK and thank you for all of your work here!

@SebHu711 2 года назад

Why aren't you dry fasting anymore? From my experience it's much more cleansing than a water fast.

@AJDOLDCHANNELARCHIVE 2 года назад

@@SebHu711 I definitely agree that dry fasting is superior to water fasting for its health benefits, however I find it to necessitate resting a lot of the time as I would get quite lightheaded when getting up from sitting down etc... with water fasting I can continue with my days as usual, for instance I do bicycle courier work a few days a week and wouldn't be able to do that whilst dry fasting. Also being able to drink tea/coffee (without milk or sugar) really helps make things more enjoyable. I'll certainly do more dry fasts in the future, but for now I'm happy with a 7 day water fast at the end of every month.

For about half a year my weight has been creeping up. Now I am about 7 kg above what is allowed. It is interesting how my body wants to keep my weight at a certain level.

Dr Fung, awesome video as always. The more I have learned about calorie intake/ restriction/ eating enough.. more confused I get. See to lose weight, restrict by eating less or fasting. However the understanding is restrict to much, lower your bmr, sometimes permanently. I exercise almost everyday and am not sure if I am eating enough. If I am not fasting, I eat when I’m hungry. Which works out to 2 or 3 meals per day. The calorie counting is heavily debated. Your thoughts? Perhaps a video? Thanks!!!

What are the implications here for the (very high protein) carnivore diet? Doing OMAD (daily feed window at 2 hours and daily IF at 22 HOURS, and periodic longer fasts) along with the carnivore diet meets this proper balancing Dr. Fung?

@angiesrecipes 2 года назад

I want to know that too. OMAD and animal based diet here..

@GBOAC Год назад

More protein will just drive insulin which works against IGF-1. So it’s better to just consume enough protein, and with carnivore that means either more fatty cuts or add in more fats like tallow or butter.

Dear dr Fung my question is a bit out of this subject but I am interested in your opinion on GLP-1(e.g. Dulaglutide) medication for diabetes or weight loss. From one of your lectures I remembered you had said that any diabetes medication that promotes insulin secretion might not be so good for us. How is it about those GLP-1 shots?

Hi Dr. Fung. I'd like to ask you about AMPK. I try to incorporate IF as a part of my weight loss journey. I'm not diabetic but I do take Ozempic to help manage the hunger and my binge eating disorder. Could you please make a video on AMPK metabolic activator? And whether it can be considered to be taken as a supplement instead of, or together with Ozempic as an extra "booster" for hunger management and weight loss (daily or in periouds when you hit a plateau). Thank you.

Much of the information coming out of longevity research would appear to vilify protein and implicate it in a whole host of maladies, including cancer and decreased longevity, precisely because IGF-1 is elevated as a result of increased protein consumption. However, as professor Don Layman and Dr. Gabrielle Lyon have emphasized, low protein diets, even IF they attenuate the IGF-1 levels, have a dark side in that such protein restriction induces sarcopenia and produces decreased bone density. The latter two effects cause a great diminishment in the overall quality of life, not to mention also contribute to increased mortality. Who would want to live a long life, after all, if say the latter third of it consists of greater dependency, frailty, increased injury, and lower vitality? So a balanced approach would be to continue with a high level of protein consumption to retain muscle mass, followed by period caloric restriction or fasting to counterbalance the IGF-1 stimulation.

I’m very sorry you’re going through this. It’s a lot. Have you tried just beef, tallow and water for 3 months or longer? Some people react to eggs, diary, chicken, and even a little sugar, so a strict elimination diet might help. Pair it with fasting. I hope you recover soon. Hugs.

00:03 IGF-1 is an important growth hormone that peaks during puberty and continuously drops until old age. 01:35 Administration of human growth hormone showed potential benefits in lean mass, body fat loss, bone density, and skin thickness. 03:11 Insulin and insulin-like growth factors (IGFs) play a crucial role in overall growth and signaling cell growth. 04:46 Both high levels and very low levels of igf-1 are associated with poor outcomes 06:21 Protein and carbohydrates increase igf-1 levels the most, especially animal proteins like milk, cheese, and yogurt. 07:50 There is a trade-off between growth and longevity due to protein levels 09:19 Caloric restriction of less than 50% leads to a decrease in igf-1 10:49 Fasting with low calories can decrease IGF-1 levels and achieve a balance between highs and lows.

Dear Doctor, you have told in one of your replies that glucose increases during fasting from stored glucose in your body. If glucose increases during fasting does insulin also increase simultaneously to counteract it? Also, I tested my blood glucose after I had coffee without sugar, approx. 10 mg/hdl increased. I had learned that it was OK to have coffee during fasting.

I've gotten very good results with intermittent fasting eating all food in a 6 hour window and fasting for 18 hours. In a recent interview Dr. Valter Longo (a leading researcher on fasting) claims that fasting for more than 12 hours a days is not health and actually lowers life expectancy. Do you have any thoughts on this. (as usual, every expert opinion on diet and health seems to get completely contradicted within a few years/decades).

You should probably cut it out, but chemo destroys the body so only do it if truly necessary. A typical fasting schedule for cancer is something like 3 days water only and 3 days eating low carb high fat. With some longer fasts if you can manage. It will help but you can't count on it to take out full blown cancer.
