Dr. Jason Fung explains how and why all calories aren't the same. The term 'A Calorie is a Calorie' assumes that only the amount of calories is important and not the type of calories. Yet different calories have different hormonal effects on our bodies which impacts their fattening effect. Check out my blog at / drjasonfung

Well... Yes but also no - both would lose the same amount of weight if calories were equated but the cola isn't sustainable because it doesn't provide a good nutrient profile. So over time that loss would be muscle and you'd have nutrient deficiencies.

Thanks, Jason for all your videos. I started to watch your videos about 2 years ago and they are very informative. I just want to share something with the audience here: I'm 71 yo. My BMI is 23, the same as when I was 18 yo. In my 20's I dropped consuming soft drinks, industrialized refined carb-based "fake food". I dropped white bread, refined sugar, white wheat flour. No more sweets, refined wheat stuff. Being a vegetarian since 27 yo. with a bit of Lacto (yogurty and cheese) for the taste, I didn't bother in looking everywhere for protein as a substitute for all the beef, chicken I used to eat. Rather I relied on beans, lentils, peas (and other Leguminosae) as the main protein sources and some protein from my brown bread, brown rice, etc... Nowadays I almost do not consume even whole wheat bread anymore and increased the intake of veggies, as I have my own organic garden (over the last 4 years). I increased the consumption of "good fats", like avocado, olive oil, and coconuts. I have been eating 90% organic food for more than 10 years. ] As I am physically very active, I have almost a "negative" belly and a swimmer's kind of body. Calisthenics is part of daily routine, I have never gone to the gym, why pay when I can do calisthenics anywhere, anytime for free? I do it even while walking or just standing in a shopping line. Some of the best things I did concerning health and nutrition: No foods in cans, packages, no fast food, no soft drinks. No white sugar, refined wheat flour things, no white rice, etc. No omega 6 vegetable cooking oils, just COCONUT oil and olive oil on salads. Organic food. And finally... over the last 2 years, Intermittent fasting around 5 days a week with no calorie window from 14 to 16 hours. I haven't been sick for decades, not even flu. Needless to say, my relatives consider me "weird", but they are all fat or obese, with diseases, always taking some pharma drugs.

Your videos have helped me find the missing puzzle piece about why I couldn't white-knuckle my weight down past a certain point just by tracking calories, no matter how much I decreased my intake and over-exercised to the point of injuring myself. My hair was falling out, I felt tired and miserable all the time, and I didn't lose more than a pound or two in two months.. go figure. Maybe some people can get lean that way, but it absolutely did not work for me. I started alternate day fasting and eating to my heart's content (even carbs!) on non-fasting days, and now the weight is just falling off, a pound or two a week. The best part is that I feel amazing again, my hair stopped falling, and I have more energy than I've had in years! I just got my parents and my partner started on IF as well :) Thank you Dr. Fung!

It's obviously a lot more nuanced than that yes - but fundamentally the only way to lose weight is to induce a caloric deficit. Trying to argue otherwise and that fasting has some magical properties is just nonsensical - it's a tool to induce caloric deficit

@hfjchan 3 жыл бұрын

@@harrywilliams6054 Caloric deficit is over simplified for weight loss. That's the problem. If you have 2 person, both of them has the "same caloric deficit" of say 500. Person A spread the intake into 3-5 meals eating all day, then his insulin will be in a certain level all day that preventing his body to use body fat. So, in this case Person A is not losing body fat. However, Person B eat the same amount of food but in a smaller time frame say 8 hours having 2 meals, then he would have 16 hours of fasting. During this 16 hours fasting period, his insulin will gradually fall into a level that his body will be able to burn fat. The important thing is not "how much" caloric deficit you induced, is "how" you induced it. And this is only talking about insulin when talking about fasting. The body react differently to different kind of food even when they have same amount of calories.

@TheSuperHarrygeorge 3 жыл бұрын

A calorie is a measurement of energy. It is not a tangible thing any more than an inch, a pint, a pound. It is just a measurement. Dr Fung is a ray of sunshine for people like me who have struggled most of their lives trying to keep their weight down on a very low calorie intake. At last after over fifty years of not understanding the concept of weight and insulin impact , I now eat many more calories but very very low carb. My weight has stayed constant.

Look, I get the argument that you extract different things from different foods for a same hypothetical amount of energy, to simplify. But it's time to LET THE "A CALORIE IS NOT A CALORIE" PHRASE DIE. Yeah, caps for visibility, not aggravation. Why? Because a calorie is a physical measure of energy. It's as silly as saying "a mile is not a mile" because if you walk or run you won't feel the same or cover the distance in the same time. But the mile does not change as a physical measure of length. A calorie cannot be anything else. It's a damn unit of energy!

Hi Dr. Fung! First of all I would like to thank you for sharing and explaining the concept of fasting and the myth of calories! I've been doing IF for almost 1 year and I've lost almost 20 kg and be able to maintain the weight I want. However I do have two questions in terms of fat loss (body fat burning) and metabolism reduction. Say if I do 22 hours fasting everyday, and during my eating window I eat just enough food which equals to my daily body energy consumption (or more), in this case will my body still burn body fat during fasting? (cause my body can get all the energy it needs from the food?). The other question is that it is hard for me to eat a lot during my eating window when doing one meal a day pattern, but from the study you shared, does that mean even I reduce my daily energy intake, by doing fasting my body will not reduce the metabolism rate?

So how does fasting increase BMR, like another video stated? Before hearing about that I had always understood that once your body adjusts and gets lighter / smaller the BMR decreases, hence the dreaded weight loss plateau ( because it thinks you are starving and tries to preserve fat) You then have to trick your body into thinking you are ok and not going to starve ( by eating a little more) so that it will adjust again. Confused.

Because they don't eat enaugh in one meal to satisfy their body's needs (to feel somewhat-full and healthy) and then don't let the body switch to ketosis whilst the fast to burn the undereated calories from their own fat to keep the metabolic rate on the right level.

Hello Dr fung a calorie is a calorie but the food group might be different.For example a 100g snickers bar has about 180 calories (approximately) But is extremely low in volume which is not satiating at all.Whereas 4 lbs of baby spinach has the same amount of calories but it is extremely high in volume along with various micronutrients.It is really challenging for someone to eat 4 lbs in one sitting.Calorie is same but food volume is different.

@@geneticsPK Under the assumption the calorie is stored. People with type-1 diabetes do not produce insulin and if they do not take artificial insulin they are nothing but skin and bones regardless of how much they eat. They will just urinate out all the sugar (carbs). A dry piece of wood has about 4-5 Kcal/gram in it but you would absorb 0 calories if you ate it because we can't break it down. The way the human body uses/stores nutrients is far more complicated than calories in/out. Even people who don't believe in low-carb, keto, fasting, insulin control probably won't argue that protein and fat is used in the body for things besides energy where the only purpose of carbs is for energy and, incidentally, hormone control. If you could someone get enough vitamins and minerals without carb foods (fruits/vegetables) you could never eat another carb again and be completely fine. If you don't get fats/proteins you will die.

@LTPottenger 3 жыл бұрын

They can't calculate it, it's pure bs. Your body will increase the metabolism to get rid of whatever carbs you are eating but it is a slow process so you will gain a lot of weight before you reach equilibrium if you do a large increase. And it does the opposite when you are in a deficit. That is why you should fast. When you skip a day of food your body does not adjust the bmr down because it takes days of deficit before that starts to happen. When you got on a diet for a week your bmr is already going down and in a couple months it's dead.

Ben Bikman phd agrees with fung, he is a biochemist. Like all bodybuilders coach greg lies about everything. He takes steroids to keep from losing muscle when dieting, and synthroid so he can up his metabolism to diet a long time. Otherwise your metabolism is in the toilet from dieting in just a few weeks.

First of all most people who diet do not care about muscle. They are not bodybuilders and they just want to be healthy. You lose more muscle as a natural athlete while dieting, but you can minimize that up to a certain point. Comparing professional bodybuilders with regular people is just stupid . Regular people are not looking to be 5% bodyfat with maximum amount of muscle ,they want to avoid the incoming heart attack you feel me?

When you do CICO diet, you compute first your BMR. Based on my superficial knowledge, BMR depends on age, weight and activity level. Thus, even if your comatose, your body still has uniform BMR and following the formula would still result to fat loss. It confuses me how foods can modify hormones and affect your metabolism/BMR. Someone please correct me/ explain further. Thank you 🙏🏽

@akilaj553 3 жыл бұрын

I think it has to do with wether you use glucose or fat for energy and what types of food you eat dictates which way your body behaves. Furthermore, if you don't have obesity issues you would likely do fine with a calorie in/calorie out & BMR situation. As you age, you may experience weight issues and at that time the hormornal effects of what you eat will become key! Everyone can lose weight on any diet but, at various ages success rates can dwindle. I am someone who has struggled with weight since my teens and have tried various diets. I found that nutrisystem worked best but after going back 3X, the last occassion wasn't as successful and the weight crawled off. With IF and LowCarb , I have consistently lost 2Lbs weekly with NO EXERCISE!!! No plan that I've been on has not required exercise! Weightwatchers, nutrisystem, Jenny craig, Beachbody &seattlesutton have all emphasized exercise for continued success and it is imperative. With IF/LC you have loss and no exercise. You may have more energy and that may encourage you to move around a bit but there is no set 30min a day routine to get your body burning. All of that speaks to foods affect on the hormones and how your body responds to the directives given.

1. Your BMR goes down in less than a week of dieting and will be down the drain for good after a couple months, making those formulas worthless. 2. Your body doesn't burn all the food you eat. It can only store fat if insulin is high enough, otherwise anything not burned as free fatty acids goes down the toilet. It's also impossible to store protein as fat, your body just won't do it unless starving and there's nothing else avalable and then you will then get rabbit starvation and die.

Carbs intake makes insulin high - energy is stored in cells. Fat makes low insulin ride - fat From meal is burned. Not eating at all for extended time - insulin gradually lowers and lipase is able to burn body fat. You literally burn your fat storages . Released growth hormone protects your muscles From burning .

If you see his other videos, it's about how much insulin inducing quality the food has. Insulin is the fat storage hormone. So eat foods with a lower glycemic load and there isn't as much need to count calories. Also some amount of fasting is helpful as opposed to lots of meals even if low calorie. The body needs time not digesting or having sugar in the blood in order to lose weight. Easiest first step is just three meals (low in carbs, moderate in protein, moderate-high fat) no snacks. Like the way we ate before 1970. Close up the kitchen three hours before bed.

I chose to simply ignore the hunger sensation, and it will go away. Funny, in the fasting evening I almost always go to sleep earlier than feeding days. Drink a lot of water and some salt if feeling dizzy. You have to prioritize your goal and health benefits over the hunger.

The 2 things I got from this video is 1) Your body adapts and lowers your metabolism when you do a CICO diet. 2) He's trying to explain that not all calories are created equal, for example, 500 calories of doughnuts are not the same as 500 calories of broccoli. I think the overall point Dr Fung is trying to get across is don't look at food as just a number (calories) but look at it in a nutritional way. Going back to the doughnut/broccoli analogy, in the CICO world, 500 calories is 500 calories, but a doughnut is high in sugar and empty carbs that don't really provide essential nutrients whereas the 500 calories of broccoli does not have any refined carbs and has plenty of vitamins and minerals that our body needs. Also, our body reacts differently to consuming these foods which play a big part in trying to lose weight.

@TC-V8 3 жыл бұрын

Simply; calories are a pointless metric when it come gaining/loosing body fat. Hormones control where and how much body fat you store. The difficulty is EVERYONE has a different hormonal response to the same foods but generally carbs elicit a higher hormonal response for storing body fat if you are not expending that energy.

I definitely agree with the hormones aspect. But there are some flaws here I'll address. It's WEIGHT=calories in vs. Calories out. NOT just fat as suggested. Also, he is assuming that as you put in less calories, the output is always matched in the decrease 1:1. It's not. Just look atbthe starvation study he cited. The participants CLEARLY did not stay the same weight with their 1500 calories. They were absolutely skin and bone. When measured, their out put in calories burned only decreased by 25%. Not 1:1 , 100%. I'm not sure why he uses that study because it disproves this theory. At least in the data. Yes, if you out less calories in, less will be burned. But it's not that drastic, and you will still lose body weight.

If CICO is the only thing that matters then you only have to vary your intake or burn by 9.6 calories per day to change your weight by one pound per year. Since I know my own BW has varied by as much as 4 pounds a day, this seems like a very small window. Obviously how your body reacts to the form the calorie is in is more important than how many calories.

Eat correctly and eat less frequently. Energy expenditure tends to go down with the combination of calorie restriction + frequent hormonal(insulin) spikes(frequent eating). Resting energy expenditure tends to remain stable when the hormonal(insulin) spikes are kept low for longer periods.

CICO is bound by the laws of thermodynamics and that can't be changed by hormones. If you eat more calories than you put out than you will gain weight and vice-versa, there is no such thing as a calorie type, it comes down to personal biology the volume of the food consumed.

@@OtherwisePanic It's not that the law of thermodynamics is defied but how much energy you can output in response to input (as well as, to some extent, absorb) has to do with the type/quality of food/drink you put into your body. As a blatant example well-known, consider TEF (thermic effect of food). If you consume 1000kcal in soda (i.e., in sugar), there is almost no thermic effect whatsoever so you burn practically no calories digesting it. However, if you consume a high-protein meal, you will tend to burn around 17% of the calories you ingest just through TEF. If you consume an extremely high-protein meal, that can burn as much as 25% of the calories you consumed through TEF. That is a blatant and well-known example supporting Dr. Fung's claim that output is not independent of the type of input. As another example appealing to common sense, let's say you drink 500kcal of whiskey for breakfast in the morning (and assuming you aren't like a hardcore Irish drinker who isn't affected).
