Access the full show notes, including referenced articles, books, and additional resources:
Dr Fung discusses the key hormone of insulin, how elevated levels of insulin in the body lead to chronic inflammation, and the physiology of how this happens. Dr Fung explains how certain foods we eat elevate insulin and cause us to store fat in the fat cells. And while what we eat matters, when we eat is also important to release adipose tissue (body fat).
Dr Fung discusses the role of intermittent fasting, extended fasting, and autophagy to reduce inflammation and why the consumption of too much protein can inhibit autophagy and mitophagy. Dr. Fung also discusses the role of common weight loss medications like Ozempic and their effect on weight loss and insulin resistance.
This episode is important for anyone who is overweight, those who have tried every diet or count calories and failed, and who seek to know the science behind how to lose weight and keep it off. You will learn the science of lipolysis (how the body burns fat) and effective dietary and lifestyle protocols to improve metabolic health and fix obesity.

The god! of fasting.
If you eat a 1,000 calorie meal, surely those calories have to be stored somewhere, irrespective of whether they are fat, sugar or protein – you cannot burn that amount of calories off in an hour, even with vigorous excercise.
I am a bit confused: isn't insulin supposed to extract energy from glucose and transport that energy to your cells? From what dr. Fung said, all insulin does is take the glucose and store it as fat, i don't understand how
Absolutely love this Dr, discovered him yesterday and been watching so many of his videos.
I love that he wants to share the knowledge and understanding

At one point I weighed 246. I was so uncomfortable in my body. The first thing I did was cut out all processed foods and cane sugar and I started eating whole foods, an avocado a piece of steak, an apple, blueberries, Greek yogurt, etc. I started exercising, basically, just doing the activities that I enjoyed like hiking. Taking the stairs instead of the elevator, basically increasing my movement.
And while I didn't incorporate fasting right away, I dropped a good 40 lbs just by cutting out processed foods and sugar and got myself moving. After I added fasting into what I was doing and added different exercises into my routine, I lost another 46 lbs within 4 months. I still have 30 to go . What I've started doing is increasing my fasting window. I'll be starting a 36-hour fast shortly & cycling protein & carb days. I've also added in strength training and hiit training. I think a lot of people get overwhelmed with all the information they get and they try to do everything all at once. It gets to be too much and they just quit. Just by taking small steps to begin with can have a huge impact on your weight and how you feel. I mean, when I first started, I just cut out processed foods and cane sugar, got moving and I dropped a lot of weight.Then I moved to the next step, which was adding in fasting. So that I think one of the tricks is don't get overwhelmed, take steps, it'll be easier to get to where you wanna be. I'm definitely going to buy his book. I love the way he analyzes things to find out what's actually the cause.
Muslims where fasting every ramadan and Thursday & Mondays for over 1400 years
So interesting
I love his no nonesense approach. Dr. Fung is a great example of a dr who actually cares about people and their overall health rather than just perscribing meds.
Question to ask. So we all understand (hopefully now after this episode) the power of insulin and it's fat storing power, and when we talk about hormone imbalance (insulin in this case) and keeping weight on, what other hormones have an effect – directly or indirectly on fat storage?
Rubbish talk, eat less calories and loose weight
Great information! I can do anything right and stick with it when I know why I'm doing it. This was very clarifying to why I would lose weight sometimes and not others.
Why does intermittent fasting not work for men with a large amount of muscle?
He’s not the “founder” of intermittent fasting 😂😂😂
❤ this doc❤
People dont overeat brocolli because it would take 6.5 pounds of broccoli to equal 1000 calories. I doubt someone could eat that amount of broccoli if given the whole day. 14 double stuff oreos equals 1000 calories which someone could eat in under 10 mins.
Calorie counting doesnt work for most people because they cant stick with it, not because it doesnt work. Why do you think ozempic has been so successful? Oh idk… cause it makes people less hungry, which equals less calories.
Is this guy really that dense or is he just trying to sell books?
Can u do keto diet when you only have one kidney?
It’s not just the insulin. It’s all the extra bs that is out in our food like sodium, preservatives, etc.
Simple it's not the same as easy LOL
I’m starting tomorrow I changed my life doing Omad Smoothie Detox but he’s right about what happens when you don’t stick to it. I put it back in of course I did when I went back to eating out everyday and ordering food. When the weight actually was rolling off when I fasted. You just really have to have that discipline.
This guy is a thief and stole 98% of his ideas from that IDF guy and the LeanGains guy. SMH
The pastured fat is where it's at. Animal Fat is the most satiating food as is fiberous food. Only real sourdough in moderation with loads of butter. And fasting every other day.
Bothers me how my surgeon who took out my gallbladder told me, I can go back to my normal routine. Eat what I like. Said as if he was God. 😮
Heeheehee I’m 60 year old female who has just discovered that fasting is easy and that I who never sticks to anything can actually do it. It is not disruptive to one’s life is not a deficit but a bonus to one’s life that the effects of feeling better is almost instantaneous and I’ve lost 10 kg in 5 weeks because I’m combining fasting with glucose goddess eating plan that reduces glucose spiking by food combinations in my meals so easy so delicious and has opened my curiosity to my body as this amazing machine and how to maintain it. 🎉🎉🎉
I wonder what DR. Colin Campbell thinks about eating so much meat?
Easiest way for me to fast. First meal at 8am last meal at 3pm. This paired with a carnivore diet are the tools I've used for weight loss. Nothing else has worked.
14 days and 1 h 14 minutes to listen to all this
I am a 64-year-old vegan who follows Jason Fung and I feel better than I did when I was 30 and have been able to get off metformin.
I’m OMAD, low carb and once a week 48 hour fast. Drop 10 pounds a month
Finally! I felt crazy made for a while. There were times I was at a pretty low caloric intake but wasn't shedding a pound, because I wasn't at a low insulin level!
Love Dr Fung. Changed my whole way of thinking about weight, food, and my body. Robert Lustig has also been a great resource.
Are legumes like beans and lentils ok to eat for diabetics
Diet coke gives me migraines
I have fasted 16 hrs a day for months. No weight loss😢
Jason Fung is changing lives and making the world a better place ❤
I have lost a STAGGERING EIGHTY POUNDS (YES ! 80 lbs) in just 4 months. In mid January I weighed 260, and by the beginning of May, I was down to 180 pounds ! The staff of doctors took me off ALL MEDICATIONS, including for BLOOD PRESSURE and CHOLESTEROL. As a mature adult, I NOW FEEL LIKE I HAVE THE BODY OF A 14 YEAR OLD teenager !
My body is evil. When my bs is high, I’d ravenously hungry! When it’s low, I have no appetite. 🤷🏻♀️
Arnt you supposed to learn how to fast for health and does clean meat and butter help get into fasting??
I have been teaching similar Stuffs online as being a doctor, I can't practice that in my Hospital after certain degree. But people are still brainwashed and fear to take a different Route than rest,even though it's totally logical.
👏👏
Calorie people" lol!😅 Dr Fung is kind of sexy! Very, intelligent. Thank you Dr. Fung❤
1:27 Doc's simples are sooooo cute❤
🙏✝️🤴😄👍👏👏👏👏👏👏👏
She looks AI generated
I lost 5 pounds in 28 days, this program to say the least is helping me to cut off my often munching snack habit.
Take away
Good more non processed foods and fast and a good guide line diet if the paleo diet.. ❤
