Doc I was diabetic since I was 13 years old .. doctors put me on insulin.. after that I started gaining more weight and I was told I’ll be insulin dependent.. after watching your videos I have my sugars in control and on medication now doctors have stopped insulin.. now I’m 28 years old .. half of my life I was worried about this is insulin injections

[@alexanderu4208]

@@samruddhikale9916Dr Ben bikman explains in his book , that when sugar is high , insulin production increases to be able to bring down the sugar levels. After a long period like that , the body starts to become insulin resistance which means it won’t allow the insulin to “burn” the sugar, so the insulin production goes even higher and crazier until you become high in glucose (sugar) and high in insulin and that’s when you become diabetic. Now , dr Ben is wondering what’s the reason doctors will give you more insulin if the only thing you actually need to do is bring your glucose levels down and stop insulin resistance and become insulin sensitive again and the diabetes will go bye bye..

Thank you, Dr. Fung. You’ve truly changed my life. While I’ve never had weight issues, I struggled with depression and neglected my eating habits. Over time, I developed joint pain, arthritis, and was diagnosed with fibromyalgia over a year ago. At 44, I considered myself healthy-until I wasn’t. That’s when I discovered water fasting, and I can’t even begin to describe how much it’s helped me. I’ve done 5-day and 10-day fasts, and more regularly, 3- or 4-day fasts. My doctor was amazed by how much I lowered my cholesterol, but he was skeptical when I told him about fasting. Despite his reservations, I refused medication because I feel so much better now. Thank you for everything!

[@basnet6342]

When you fast the body burns fat but doest it store everything you eat after the fast? it anticipates a calorie deprivation and stores everything that goes in.

We started "The Obesity Code" diet about 4 months ago. I'm closing in on 40 pounds lost and my wife is killing it too in fat burn mode! We feel so much better and are eating real food. That hardest part for me was getting used to intermittent fasting... but now it's an easy habit.

[@michelep.7249]

I tried the keto diet and I craved carbs all the time. I couldn't stay on the keto diet. I found the Mayo Clinic Diet book by Donald Hensrud. This book taught how to measure calories in foods so that you will lose weight. This book also taught to have a serving of fruit (my favorite is a cup of cantaloupe) and a nonstarchy vegetable with every meal. This book also taught to eat unrefined carbs, like steel cut oats instead of instant oats. I lost weight following this diet and have kept most of the weight off since 2021. I weigh myself every day to ensure I am not gaining weight back. I now do intermittent fasting having two meals a day and sometimes one meal a day especially if I am going to a restaurant and eating a lot of calories for one meal. I don't follow the diet as religiously as I did when I first used it to lose weight and have more fat in the diet and more refined carbs than recommended, but I still measure calories to ensure I am not overeating calories way too much. I also only eat one meal a day sometimes when I have overeaten calories on another day. Weighing myself daily helps ensure I am not gaining too much weight. I also do one meal a day when I want to lose the extra weight I see on the scale.

[@SimplyHuman186]

No. Insulin normalization is much more important to release fat, then counting calories.

[@michelep.7249]

​@@SimplyHuman186Read Proteinaholic by Garth Davis, a gastric bypass surgeon. All of his patients have tried the keto diet, but none of them were able to stay on the keto diet longterm. Also read Mastering Diabetes book by Cyrus Khambatta, a person with a master's degree in nutrition sciences and a type 1 diabetic. In this book, Khambatta teaches the dangers of being on a keto diet and teaches how a diet very low in fat causes him to require less insulin per gram of carbohydrate he eats.

I was told if it didn't grow naturally in the ground or look like it once ran around a field don't eat it. Iv been doing this for 3 months along with fasting & my skin has cleared up so much, i started noticing a difference after 3 weeks. My specialist advised your metabolic health is a massive part of the cure as your skin is the biggest organ & recommend the diet & Jason's methods.

[@msromike123]

Such an important concept that is misunderstood by so many. Unfortunately this includes some physicians and many dieticians. All I know, is I lost 70 lbs from a high of 228 lbs by following these fairly easy to implement guidelines. One of the PAs was worried about me being too "skinny" even when my weight is smack dab in the middle of the normal BMI bracket. She was very concerned I was skipping meals. The sad thing is when obesity is so normalized that a healthcare provider feels that normal BMI is "too skinny."

[@ChadSharkeyNursePractitioner]

@msromike123 Great work on your weight loss!!! The other part of that is that education is still focused on 3 meals per day PLUS snacks. So, most of the providers and dieticians are still preaching that information they were taught. The education needs to change.

[@msromike123]

@@Blackandwhitecat-u9v Yes, there are always outliers. But if you look at the American population as a whole, you do not find that feeding continuously works for most people. Genetics are involved, and most people are genetically pre-disposed to processing and storing fat efficiently. Providing a continuous source of glucose with continuously high insulin production will inevitably lead to weight gain for most people. I am assuming the people you refer to that eat all the time and are thin and healthy probably aren't subscribed to a KZbin channel run by one of the most renowned physicians in the weight loss domain.

Through not overeating anymore? What a revelation!

[@SerenityFitWellness]

@@dan-qe1tb I actually eat more now than when I was constantly counting calories, in a deficit and low energy. By understanding that insulin is the key to fat loss, and timing my eating accordingly, thats how I lost all the weight. So yes, going against the conventional wisdom of just eat less, move more ; eating bigger more nutrient dense meals less frequently; and paying attention to how insulin works is how I lost 40 lbs. So yes it was a revelation indeed 🙂

[@dan-qe1tb]

​​@@SerenityFitWellnessInsulin is not the key to fat loss. Jason had presented an oversimplification. Insulin just happens to be the hormone that stores fat. That doesn't mean that reducing the level of that hormone alone, will help you lose weight. Have you had HOMA-IR done before and after your weight loss? I too have started eating fewer and bigger meals, and it's to try and get a bigger insulin secretion and thus lower my A1C. I wasn't gaining weight when I was eating six times a day.

Thanks for enlightening us with the right information Dr. Fung! 😊

[@TorBoy9]

Please note that your body does not differentiate between "natural" or processed foods. High carb foods such as potatoes, rice, pasta, oatmeal are "all natural" but will still spike your glucose and therefore insulin. High sugar fruits such as bananas, mango are "all natural" but will also spike your glucose and therefore insulin. Look at all foods equally, whether highly processed or not, through the lens of high carbs/sugar.

[@AdrianBota1]

To lower insulin I use: acedic acid from ACV 15 ml per day, berberine, cinnamon, omega3 2gr per day and 1h walking and 1 liter of green tea. It works, I lost 0.2 kg fat mass per day

Thankyou for clarifying the pivotal role Insulin has on fat burning. The nuanced effect insulin has is always overlooked and leads to so much misunderstanding on how to unlock our body's stores of fat. Our metabolism is inherently 'lazy' and will quickly adapt to reduced caloric intake to conserve energy expenditure; something no diet-fad book from the last 50 years has ever acknowledged.

A nice explanation of biochemical events controlling lipolysis. Insulin does indeed inhibit hormone-sensitive lipase in adipose tissue by promoting its dephosphorylation, resulting in inhibition of lipolysis. On the other hand, epinephrine can counter the effect of insulin and stimulate lipolysis of stored triglycerides by activating hormone-sensitive lipase. Perhaps exercise that promotes an increase in epinephrine release could contribute to unlocking the insulin effect on lpolysis!

IF is amazing but when you get older it doesn't work as well, sure you can say fatloss is hormones not calories to make it sound more unique but that changes as you get older aswell, before fasting was a super big deal mike chang had a guest who was interviewing schwarzenneger for a book, he even stated as you age towards 30 your HGH the miracle fat loss hormone (fountain of youth hormone) slows down eventually, at 30 it stops, after 30 it drops. I skip breakfast (due to IBS) and its lost its effectiveness, we need to remember its no different from calorie cutting (even thomas delaur says dont' fast too much like calorie cutting it STILL can plataeu). Finally people who love IF should also show us their bellies, are you losing weight enough to be ripped? if you're then you're not the best people to help, because anyone can lose weight, efficiently is the hard part, looking lean and muscular is even better. I'm at a point skipping 3 days of eating (water fasting) was the ONLY thing that helped but the 2nd time i did it even the body wanted to adapt, less results and i was more hungry then round one. IF works but only to some extent

I do intermittent fasting once or twice a week (18/6) for autophagy mainly. But, strangely for weight control I think I do better with a daily 14/10, 2 meals a day. I tend to over do it on the one big extended eating window of 18/6 and will be bloated in the AM. Also, I am finding what you eat is very important. I eat salad, olive oil, organic produce, peco-romano cheese, bread and potatoes. I am not convinced that I do any better with an extreme low carb diet. Sounds like the majority of people do well with the normal recomendations, but I am discovering that a natural Mediterainan diet works well for me, weight control, consistent energy, and well being. I think you have to experiment to find what works best for you.

[@paulawhittaker3538]

Best comment especially the last sentence. We all have to find what suits our own body. If there was one universal diet that worked why arent we all on it? Life isnt black & white, theres alot of nuance.

[@Clinueee]

Problem with "low carb" diet is that it doesn't tell me how much and what proteins you are eating. Often I see that low carb diet is actually implemented with very high proteins and protein in a low carb diet still demands a lot of insulin. There is no real "fat only" foods so at end of the day restricting food amounts is necessary to low insulin levels no matter what you eat.

[@ipman8646]

@@Clinueee The odd thing is that cultures like Okinawans eat like a 10:1 carbs to protein, and have low diabetes and one of the highest longevity. But, they eat a lot of sweet potatoes and vegetables, not refined carbs. My focus is to eat lots of salads, cooked veggies, and potatoes, with some breads and cheese + lots of olive oil, while reducing meat consumption. I will say it is hard for westerners like me who grew up on cheeseburgers and fries, sometimes I want rich food and cake! And, I do cheat a bit. Don't make food slavery, but take some of the good advice from the health peeps on youtube and do your best. Also, limiting total amount of calories is important, but you have to be satiated at the same time, another balancing act.

[@rawrss]

Thank you Dr. Fung. Building on intermittent fasting, does any scientific research guide us on *when* the optimal time to workout (while fasting)? Before? After? During? Thanks.

[@donnajacques3781]

Love the analogy.

[@spartacusjonesmusic]

This makes perfect sense to me. One question: we rarely eat foods in isolation, but rather in combination. Potatoes alone has a huge insulin effect. But what about potatoes combined with steak or eggs? Does the protein and fat mitigate the impact of the carbs? Thanks!

[@michelep.7249]

If you read the Mastering Diabetes book by Cyrus Khambatta, you'll learn that fat also causes insulin resistance. When you eat fat it automatically is used by cells, then when glucose tries to get in your cells, the cells are less likely to open to insulin to allow glucose into the cell. Khambatta explains this is in detail as he received a degree in nutrition sciences. I like the book The Mayo Clinic Diet by Donald Hensrud. The book teaches how to measure calories to ensure weight loss. It also teaches to have a serving of fruit (favorite is a cup of cantaloupe as it keeps me full) and a nonstarchy vegetable with every meal. I can't follow keto diet longterm and crave meat too much to be vegan. I can however follow intermittent fasting and eat only one to two meals a day.

[@ArmadilloGodzilla]

Fat doesn't cause insulin resistance... The mechanism you describe is the Randle cycle and is perfectly normal.

[@michelep.7249]

@@ArmadilloGodzilla Read the book Mastering Diabetes by Cyrus Khambatta. Khambatta is a type 1 diabetic with a nutrition degree. He explains the science behind why fat increases insulin resistance.

Whats does exercise do? Does it lower insulin? I practice IF but i also exercise regularly.

Dr. Fung: I found out from a recent podcast that the French eat a sweet breakfast. A typical Frenchman does not eat sausage eggs and bacon for breakfast. You have discussed the French paradox. Why don't the French have a bigger problem with obesity? Pardon the pun. The French cuisine does have plenty of pastries. If you have an explanation, I'd love to hear it.

[@jackiedelvalle]

I've lived in France. There are tonnes of bakeries but traditionally they have a small breakfast, a lunch and a dinner and they don't snack in between. Same as the US in the 50s: no one fat even though everyone had bread and potatoes and oats and allsorts. BUT they weren't eating 6 carb-heavy meals a day so they were effectively fasting between meals and therefore not as much insulin storage as in the SAD - constantly eating and snacking ALL DAY

[@debiwillis9045]

Their sweets are not at all like ours. They are BARELY even sweet, my husband who has a terrible sweet tooth, won't eat them because they aren't sweet enough for him.

[@Jimfrenchde]

@@jackiedelvalle Do the French eat more protein foods than we do? Do they add butter to vegetables? My hypothesis is that obesity is caused by malnutrition. I don't think we are eating enough protein and fat and subsequently we overeat on the remaining nutrient, carbs.

[@Jimfrenchde]

@@debiwillis9045 I think our palette is different than the French palette.

[@DG1965]

The aim of this and other similar videos is to explain how insulin affects fat storage and loss and also how to regulate it by the proper way of eating in order to make it work in your favor. The doctor has once more explained it in a most comprehensive manner. There is no point in saying that the french, italians, germans or whoever eat this and that and are not obese. Sounds a bit like searching for an excuse in order to eat more sugars. Reminds of the uncle everybody has who was a heavy smoker and still lived until it's 90s. 😅 Let's just stick to the take away of this lesson: Insulin level low -->releasing fat for burning-->fat loss. Insulin level high-->fat can't be burned and gets stored.

[@mariwarren9897]

I ❤ Dr Jason Fung Thank you for sharing your wisdom with us!

[@vadimkravets9209]

I have been thinking of this food - energy/calorie pathway from a different angle, and came to a realization that one important intermediary gets often unwittingly omitted. The Mitochondria. We tend to perceive food as a direct energy source for ourselves. However, in reality, it’s an energy source for the mitochondria. Only after feeding the latter we get actual calories in a form of ATP. Since fat produced 9 ATP molecules vs 3 from sugars, it must the preferred source of fuel for the mitochondria. If it weren’t we wouldn’t have evolved to store fat. So fat for optimal long term functioning and sugars for short term storage and crisis preparedness.

[@susanolson3611]

[@spooktastic0410]

Semaglutide increases insulin production, how then does it induce weightloss? 🤔

[@Sheenasalesthriftytreasures]

Thank you Dr fung

[@MK-kg5wp]

I think the best way to interpret what he means is STOP COUNTING CALORIES! Instead COUNT the CARBS. If your carbs come in a bottle or package or jar or squeeze bottle (soda- chips - crackers - bread - pasta spreads, dressings, etc) and you eat it... you're raising insulin and your body is storing those foods in your fat stores. Then you fasting and you're not losing the fat you already had on your body .... but losing only the fat (carbs) you stored from your last few meals. You finally fasting long enough to bring insulin down... just to eat some more packaged foods to put that burned fat back on the hips. 😮 ugh... so simple - yet so very difficult!

[@kathyhines8939]

Great explanation, thank you.

[@serenitygoodwyn]

Couple of question: Which law of thermodynamics says anything about mass, let alone weight? Explain how the human body is a closed system as defined by physics (engineering defines a closed system differently, but we're talking physics)? How does the human body turn heat into mass, let alone a force (weight)? What is the biochemical pathway that allows heat to be used to undertake work (using the physics definition of work) in the human body? Why don't you weigh more standing at the top of a mountain despite having greater stored (potential) energy? And before you fail to answer the questions I suggest you ensure that you have a knowledge of thermodynamics at least equivalent to the a first year undergraduate degree in the UK (2yrs undergrad in US) or you're probably going to get the answers wrong! If you do have an equivalent knowledge and this is the first time you're thinking about this, prepare to be even more distressed by the state of 'nutrition science'. Conservation of mass, not conservation of energy is what matters with regards to body mass, gain or loss. conservation of energy and conservation of mass are considered to be independent in chemical reactions. It sounds like it's splitting hairs but it's not, it's a very important distinction with regards to what we eat and it's effect on our body mass and by extension our weight.
