How to Lose Weight With Intermittent Fasting In 2024 (Backed By Science) | Dr. Jason Fung

[@westfield90]

Dr Fung is such a hero of this field.

[@joannawieczorekmd]

Deep admiration for doctors like Dr Fung who tirelessly pursue the root causes of chronic conditions, utilising simple yet profound methods like fasting. Big respect to you Dr Fung.

[@MargotWOMBACHER]

Intermittent fasting is extremely beneficial and cutting out sugar and refined carbohydrates add more benefits. I am 86 years old and was in the prediabetic range. Now after 9months I have lost 25 pounds of weight and my bloodwork shows I am no longer prediabetic, triglycerides are way down HDL is up LDLs are 62 and 63 . I feel absolutely great. I will continue to try to get my A1c down more it is 5.9 and I want to get it down to 5.5 or below. Unfortunately Drs do not order fasting Insulin levels which would be beneficial, but I can do without. Thanks Dr. Fung, a year ago I listened to one of your podcasts and then right away bought your book about fast ing, what an eye opener!!!

[@AnonEeMouse]

I had a patient a month or two ago who was failing on Trulicity with a HgA1c of 9.8. I told her she needed to use Intermittent Fasting. I saw her yesterday and she is off the Trulicity and all meds and now has a HgA1c of 5.1. IF works.

Absolutely - 100%! People are running around trying to avoid their feelings, whether it be with food or TV or gambling or work or drugs and alcohol or video games, etc. You have to FEEL the feelings to ultimately come to the conclusion that they mean nothing and won’t hurt you. In fact, feeling them is the only way they won’t hurt you. People take their thoughts and feelings seriously, and act accordingly. We’ve got so many people reacting on auto-pilot, because they don’t take the time to let thoughts and feelings come up and out.

Some of us can’t even eat veg carbs. I went carnivore, lost 64 lbs and reversed my pre-diabetes. Hormone doc told me to stop eating so much meat and add back in some veg. Gained 20lbs, A1C back up to 5.9 from 5.4, and fasting glucose is high now. My body also hurts, and I’m having night sweats again. I am going back to carnivore.

[@lauratyler8869]

Hi. Would you give me some guidance for the carnivore diet? Where to look? There is so much info. Not always accurate! Thanks

Very interesting. I struggle with carnivore because I don’t love meat. So I do have some vegetables. How did you get to the point to where you were all meat AND do you hit your protein recommendations on days you eat?

[@martinugalde2324]

Yes for me was easier to go carnivore me being mexican I just cut out the tortillas and the rice 😢 but it worth it no longer on diabetic medications I fast and feast like a king 😂

[@samum5856]

I started intermittent fasting 16:8 - I started eating at 10:00, finished at 4:00. At the beginning it was difficult. Now, 10 months later, I am so not hungry anymore that I often finish eating at 2 or earlier. Sometimes I could eat just once a day out of hunger, but I eat twice because I like to eat! Lol!

[@KCallaAK]

I've listened to this twice. You are both such kind and caring professionals. I laughed at Dr. Fung's rendition of the Kempner rice and sugar diet. My thoughts exactly! I'm maintaining a 65 lb loss since 2010. Now, at 68, I'm moving to IF and am feeling such freedom in not having to think about food all day long! Completely new mindset. Thank you to both of you.

[@CatholicHousewife2017]

Maybe white rice with lots of butter & a little maple syrup - but after 3 days, I'd be so over it. Meanwhile, I'm only eating meat, bacon, poultry, sausage, butter, eggs, fish, & a little cheese in my diet & my body feels so great on it!! Meat-only or Carnivore, I don't care what it's called - so many ailments resolved or resolving & in noticeably stronger at 50yrs old ❤

[@KowanRobbins]

Dr Fung. I can tell you are getting a little aggravated by trying to tell people the answer to why we gain weight or get diabetes, but they are just not listening. 😂it's not a drug you have to take or the thought that some people can't lose weight because they have no control or don't really want to. It's understanding the true why. You have saved my life by teaching me to understand my body and taking control back. I now have an amazing relationship with my body. You da man!

[@martarico186]

How do you explain a low insulin with pre diabetes on a 2 year carnivore diet? 13- 16 hrs intermittent fasting. No weight issues.

[@LauraB.335]

@@martarico186Judy Cho on Nutrition with Judy addresses this. If I’m remembering correctly, it has to do with cells living longer when you’re on carnivore.

[@FoodiesFoodLife]

I'm 65, I'm recently diabetic... I'm using Berberine. And I've been losing weight and my morning blood glucose is going down. Recently I added intermittent fasting... it's not as hard as I thought it would be. But sometimes I don't. I think it is something you need to do intermittently. I think IF is much better than trying to follow a diet (my favorite 4 letter word). But I'm not in a hurry to lose weight. I just want to be able to keep it off.

[@SCharlesS]

Wow. This is what it feels like when an interviewer doesn't interrupt a guest. Well intentioned or not. Refreshing. Subscribing....

[@homomorphic]

One reason there is so much idiocy surrounding this, is that the generl public simply refuses to acknowledge the well established fact, that fructose is addictive. If we talk about fructose consumption in that context (as an addictive substance) then everything Dr. Fung is talking about is just patently obvious. Fasting is a proven mechanism for helping fructose addicts break that addiction. It is as simple as that.

I was amazed to find eating carbs and lowering fat actually cause me to loose weight. I used to fast and lost some weight. And hair. Now using macros and finally getting the success I've been craving since I read The Obesity Code. Oh, and I thought I was addicted to sugar too but turns out I just needed to actually be accountable for what I am eating and eat enough protein and carbs to provide adequate nutrition. Calorie deficits come in many forms.

Try to greatly eliminate ALL grains, wheat, sugars, carbs, etc. If you can accomplish this, you’re on your way to a major transformation.

to make it easy for me to fast, I got into keto first. I eat bacon, eggs and butter for breakfast 6am and eat the same thing 6:00 pm. 12 hours is so easy to do . I learned alot watching Butter Bob Briggs

[@pamisntcraiganymore]

I finished my first 72 hour fast yesterday (at least the first in several years). I could barely have a full meal and in no way get a full day’s worth of protein and fat. So I am trying again today to get a full day of nutrients. It is daunting. Vegetables barely have any protein, I can’t stand beans, don’t eat wheat or rice or potatoes AND looking at eggs and beef is making me feel ill. Prior to this I was doing about 1 meal a day I am wondering if it is ok for me to continue this way. I am losing a lot of weight in water and fat but worry about my set point in the future when my appetite is normal again.

[@CarisaRae]

Yes, I definitely notice if I don't get enough protein I remain hungry

[@glorianewsom6200]

I appreciate that you discuss scientific beliefs and fad diets by dates, because I believe the average person dorsn't know about these changes. I had no idea that doctors are trained a bit differently each decade (based on new science results)., or that far wasn't as big as issues at initially thought, or that eating a "balanced" meal plus a cookie is better than eating just the cookie (fewer calories total). My knowledge (burn in the 60s, elementary school on the 70s, and high school in early 80s) stopped there. I was not aware of much after the early 80s. 😮

[@ellieantar809]

Love tthe Docs directness refreshing

[@homomorphic]

I know Dr. Fung knows this, but higher insulin levels do not make you hungrier, the problem is that fructose is a leptin antagonist. Leptin is the prinary neurological satiety hormon. So when your insulin levels rise in concert with fructose consumption, your brain is essentially unaware that you've eaten. The issue is that any one on the SAD has high insulin in concert with high fructose (fructose does not increase blood sugar of course but fructose is consumed in excessive quantities at the same time as glucose when on the SAD).

[@susans.magallanes3861]

He answered, fasting is a tool, choose the variation that helps you. You will lose fat, muscles and hair. But to prevent muscle loss you have use it. Good luck.

[@markotrieste]

​​ @susans.magallanes3861 It's four years that I use variations of fasting. I don't measure lean mass directly, however I have improved both runinng and lifting performance. Fasting gives me clarity and focus, which in turn helps me with motivation for working out more and more consistently. As for hair loss, no sign of it. Regarding the video, the answer about sarcopenia comes about seventeen minutes later, at 57:34.

[@susans.magallanes3861]

@markotrieste ah, congratulations, you found the answer! Variations, that’s the beauty of human body, isnt ? Yes, I didn’t measure too anything, but my first attempt was to serious fasting results in terrible hairfall. After starting to my food journal, I realized that it is due to insufficient intake of protein. Adjusted and it didn’t happen anymore

Anyone who has taken Berberine with positive results, can you share which brand and dosage and when? There are so many brands like 😮 Berberine and SuperBerberine 🤔

[@elenaceciliacojghiceanu3078]

Berberine 500mg/ Zenyth twice a day before meals. It did lower my blood glucose But if I overeat I still gain weight ☺️( I eat a lot my first meal as I get so hungry). For me it is ok if I eat less and IT, if not, I gain more weight.

[@elenaceciliacojghiceanu3078]

But I also do exercise almost every day, I do my elliptical bicycle 30-90 minutes and lifting weights 1-3 times per week.

[@zeldalazino463]

I’ve heard that Dihydroberberine is even more effective than regular Berberine. The brand I use is regular Berberine from Enzymedica. 500 mg with each of 2 meals/day. When I get close to finishing this bottle I’ll start to take the Dihydroberberine.

GLP1 do not take All enjoyment of eating out of your life.

I may not enjoy big meals, rich food and eating to Thanksgiving choices satiety; I am also able to control my unconscious snacking and cravings for unhealthy and too much food.

[@EmpoweringCoach]

I just like to set the record straight about the rice diet it was not just rice and sugar. It was fruit, rice, fruit juice and sugar only for the patients that were dying and most were underweight and had kidney problems, so it had to be low in protein and that is why, rice was consumed. This was not a weight loss program at all. I'm not sure where you got your info but it's incorrect and misleading. A weight loss center and diet was created afterwards. They ate fruit, grains, starches, vegetables, legumes and possibly once a week meat. There are also are weight loss books that have all food groups in them for the rice diet. I have actually been on it and never was hungry because I eat too I'm satisfied. Please correct your error. So again this is not a rice and sugar diet and this program is very satisfying. And I've never stopped being a program because people have been using it consistently on their own. There are Facebook groups and your diet books. Dr McDougall talked about it often. He based his starch solution off of the rice diet.

[@Maia-d7m]

Omad rise my GI too much. 3 meals a day high in fat or even only veggies (starch) + fruit keeps it low. I wish it worked for me but it doesn’t. Also, impossible getting all magnesium and potassium in omad, and I develop deficiencies no matter what I supplement. I’m lean and very active (workouts + physical job), just looking to maintain in a comfortable way with a routine and minimum cooking.

[@sharonalicea7998]

So, what happens when someone is just not hungry? I’m not hungry or snacking at all. I’m carnivore. I don’t eat carbs. But the weight just won’t budge. I’m lifting weights 5 days a week and walking to reach 10k steps + every day. I need help. A dr offered Ozempic, but like I said, I don’t need to control hunger. I’m hyperinsulinemic (diagnosed by dr with blood tests). I’m overweight and need to drop 30 pounds (fat).

[@GenRN]

Try water fasting with electrolytes until you get hungry. You aren’t hungry because your insulin is so high. It may take you doing a long fast to become hungry. You need to get into ketosis and burn up your liver fat.

[@GenRN]

Also, stop the vigorous exercise. It makes your body produce more cortisol because the exercise is a stressor. Gentle walking only.

[@hockeymomavalon2499]

Try dry fasting. Look up August Dunning, and Dry Fasting Club. It works and it works fast !!

[@SCharlesS]

The other replies assumed you are not fasting. I find it hard to believe you are watching dr. Fung and Thurlow and haven't tried extended fasting of at least 3 days. You did fast for a long period and cannot lose weight before thinking about ozempic or writing this comment?

[@LauraB.335]

If you have high insulin, you need to lower it. I know you know this, but it’s hard to know why it’s not lowering without more info. You say you’re not hungry, but how often are you eating? Are you eating enough fat? How long have you been doing this? Perhaps, there are other things that need to heal before you lose the weight. Is your body composition changing, despite the scale not changing? Are you feeling better overall?

[@mettacognatus5849]

What do you think about the scientist's work (Dr. Stacy T. Sims) and the fact that she is discouraging the practice of exercising on an empty stomach, especially during menopause?

From the (Peanut Gallery) personally, I'm menopausal and my body is always adjusting hormonal wise fasted exercise (Cardio) has been beneficial re: any excess glucose around which allows fat loss however, when resistance training to maintain muscle yes having nutrition is KING overall it's valuable to be our own N1 experiment in my opinion given my experience full disclosure is without HRT at this time I will begin replacement eventually.

Dr. Fung: there are natural ways to increase testosterone levels in males: weight loss, exercise, healthy eating, supplements,fasting. All of these help. The graveyard of testosterone is fat cells. Please review my response because we know!!

[@CarisaRae]

Those of us that fatten easily need to fast more

[@vickiesorenson2383]

I have a question here. Excess proteins if the body does not use all of them, they will be turned into carbs and fats. So eating mainly protein and also fat is no guarantee that you will lose weight. The fat can accumulate and also clog the arteries and cause other problems like heart attack or stroke. Where is the balance here?

[@darkglass3011]

​@@y.g.1313 "I do this for long term longevity benefits of which Dr. Fung has zero idea" It is you who doesn't have any idea what you're talking about. Dr. Fung actually talks about the same long term benefits of fasting on his KZbin channel that you're talking about. If you weren't so ignorant and easily triggered, you'd know that Fung knows about and actually supports the things you're talking about, but instead, you've shown everyone how ignorant you are. Fung in this video is talking about people who has unrealistic expectations of fasting without understanding what it's supposed to do and how it applies to their own body. Yes there's autophagy, but for people who only care about losing weight, they'll say that "fasting doesn't work" because it doesn't achieve the results they're looking for. The mechanism of fasting depletes fats because that's how it works, so if you're lean and muscular, of course you're going to get different results than someone who is obese because the person who is lean barely has any body fat at all. It's actually very embarrassing for you to talk the way you did about someone who knows about and supports the things you're talking about. Very shameful and humiliating.

When you encourage keto/low carb & fasting to people you are also responsible for making them cautious about losing water from body enormously which could cause losing important electrolytes/body minerals which could end up with increased heart-rate or palpitations other possible kidney complications etc..!

He's talked about salt and electrolytes. Gotta watch more and pay attention. Loud and wrong is not cute. Those who have studied this subject with Drm Fung and Dr. Berg know all about getting your electrolytes including salt and potassium. Healthy keto is making sure you get your 7-10cups of green leafy veggies daily. And some ppl have to build up their veg intake because they don't have enough gut bacteria to break it down properly. We know what to do though. You tried it.
