Cutting Calories Doesn’t Work – It’s simple Algebra ❌🥗 || Jason Fung
Cutting Calories Doesn't Work – It's simple Algebra ❌🥗 || Jason Fung || Dr. Jason Fung Explains the Truth About Weight Loss & Insulin!
Are you tired of hearing that the secret to weight loss is simply cutting calories? 🧐 Well, in this video, Dr. Jason Fung breaks down why calorie counting has NEVER worked and why it NEVER will! 🚫
Let’s talk about the real reason why we gain weight and how calorie cutting can actually backfire. It’s not just about “calories in vs. calories out” – it’s WAY more complex than that. In fact, hormones, especially insulin, play a HUGE role in how your body stores fat! 🔄🍔
Key Points Covered:
1. Body’s Adaptation: When you cut calories, your body actually fights back by reducing energy expenditure, leading to a weight loss plateau. 😱 This is why calorie restriction alone doesn’t work long-term.
2.Role of Insulin: Discover how insulin plays a critical role in weight gain by telling your body to store fat. 🧬💡 It’s not just about calories, it’s about the hormonal balance that shifts the relationship between calories in and calories out.
3. Circular Logic of Dieting: You’ve heard it all before: "You’re gaining weight because you’re eating too much," but Dr. Fung explains why this is a classic case of circular logic that doesn’t solve the real issue. 🔄🤔
4. The REAL Solution: Instead of focusing on calorie counting, the focus should be on what causes the imbalance – hormones like insulin. Dr. Fung gives insights on how to tackle the ROOT cause of weight gain. 🌿🔑
Forget the traditional methods of counting calories and learn how to fix the real problem behind weight gain. 💥 Understanding your body’s hormonal response is the key to lasting weight loss and better health.

Jason, what’s happened to your channel? Since yesterday it’s not the same as usual!
HES BACK!!!!!!!! screw you elon! 😁
Huh? Please explain
@@greensmoothie3456 Somebody hacked the channel and was running a “livestream” that was a video of Elon talking politics. At one point over 110k people were watching it live according to YouTube. Then the channel went away. Now it’s back.
@@RictorIAG thank you!
I’m done with Fung
@@RictorIAGlet’s hear it from Fung. He hasn’t said anything about this
Pro tip : no matter what you eat, eat a little salad before your meal, and you will stay way longer full + energy gets released slower.
What about oxalates
@@jamesdean7756
Plenty of dark, leafy greens that don’t contain oxalates.
Love the fact that your are the ONLY person that says this on record.
Dr Fung is indeed a people doctor, straight and plain talking about and for people health benefits, no monetary strings attached. ❤️🙏
no he’s not.
Hi, may I suggest that you tilt the camera down a bit more. Your framing right now makes you look like you’re about to sink from the frame. 😀 I subscribed twp years ago.
Water has zero cals yet it is weight. Wood, coal, gasoline are all also calories. We do not “burn” calories like a bomb calorimeter does
I feel like you have all of this backwards. You see hormones – particularly insulin – as the cause of weight gain/loss. But it isn’t the mechanism, it’s the signal. I think we would all be better served by looking at the mechanism and how it interfaces with the signal. That might provide additional insight.
The mechanism, which I’m sure you are aware, is called the Randle Cycle. This describes how cells use fuel in the body. And the very first thing we come to realize is that the body doesn’t burn calories. Ever. At all. Instead, it oxidizes substrate. And past that, how much substrate is oxidized depends on how well the body is setup to oxidize that particular type of fuel. The fuels being glucose or fatty acids. Research has shown that fat adapted eaters oxidize over 3x as much substrate per minute during exercise as high carb eaters. We’re talking about grams of substrate, not calories. So calories is a nonsensical way to look at this from in the first place.
We need to look at substrate. That is, the fuel being used by the cell to create ATP. As already stated, there are two options: glucose or fatty acids.
But the Randle Cycle tells us something interesting: when the cell is oxidizing one type of substrate, it inhibits the other. Meaning, when the cell is burning fat, it retracts the glut 4 transmitter turning that cell locally insulin resistant.
This is information that seems valuable to know but can’t be known just by looking at insulin alone. The reason the individual cell can’t take in glucose is because the transmitter has been withdrawn from the outside of the cell. The signal literally can’t reach the transmitter.
The real problem then is mixed fuel meals. Eating a high quantity of carbs and fats at the same time jams up the system. The body has to deal with both glucose and fatty acids impacting the body at the same time. Now, each cell can determine what it is burning but moving from one to the other is a bit like turning an aircraft carrier. It’s not instantaneous. But one thing is sure, at least some of this glucose will be shut out of the cells because those cells are currently locally insulin resistant.
It’s important to note that the cells are doing what they are supposed to do: protecting themselves. This is not a pathological response.
The effect is glucose pooling in the blood which the body then takes through lipogenesis to create body fat to get blood sugar levels back to normal. Also, this pooling of glucose in the blood can be measured by looking at one’s A1C measurement, which is a measurement of the damage that excess sugar in the blood did to red blood cells.
So you see, insulin didn’t do anything but signal to cells. The mechanisms in the cells is what is most informative. You’ve been beating the insulin drum for quite a while now. It would be nice if you could approach things from the other side, as I’ve just articulated. The Randle Cycle is vastly under discussed and I think you could add value to this discussion.
Hallelujah…,at last someone who understands metabolism ( not that Dr Fung doesn’t btw). I totally agree that not enough people acknowledge the worthlessness of the term “calorie” and how the body actually converts substances in to useable energy.
The problem with obesity is ultimately just insulin resistance; a metabolic dysfunction of the body, even if insulin (the communicator) is not the true root cause, it still tells us what is wrong. Fasting will address these issues 99/100 times. I think your story is accurate and you have solid points, but I think we should focus on offering easy surface-level translations: teach people how to fast, and the results will show.
Tell me you haven’t read The Diabetes Code without telling me you haven’t read The Diabetes Code. He says exactly what you are talking about.
Not true at all. I did Keto for 11 months then Carnivore for the past 5 months and gained 5 pounds. I ate no grains, no sugars, no seed oils, no dairy on an 8 hour eating window ending at 6pm. I then started counting calories and now the weight loss is in progress. Just cutting out carbs didn’t do much at all. I was on less than 20 grams of carbs a day, usually much less and near zero on carnivore for 5 months and still gained weight until I cut my calories under base calories needed to maintain weight.
Did you do a dexa scan, or other tool that looks at percent fat, muscle etc to see if the weight gain was muscle. Number on the scale is not always the most important. Until number on the scale is no longer looked at as most important, a person will never think their metabolic health is improved. Hope you haven’t limited your calories s much you are now losing muscle.
Let’s play a game: Take a shot every time Dr.Fung says the word alcohol or alcoholism. Cheers!
I do OMAD with a 20 hour fast. I have a four hour window to eat. I don’t count calories as I feel full and don’t feel the need to overeat.
I have been doing intermittent fasting for many years. Lately, more and more people are saying that eating fewer calories is just as effective for weight loss. And that fasting in many cases results in a protein deficiency. It is also said that autophagy does not occur because you have to fast for many days. This drives me crazy. All different opinions.
Does it work for you? Then fine, go ahead, otherwise change. I am perfectly happy with IF, low carb, high protein diet.
@@markotrieste Yes it does.
Glad you got your channel back
I would have like to see a “now that we’ve debunked xyz, here is the way forward”
Instead of leaving us with “calorie counting and restriction don’t work, roll credits, good luck out there.”
Watch the rest of his videos. Better yet buy his book if you really want to understand it in much less time than watching all of the videos. Two words. It works.
If I eat to much even keto/ carnivore I gain wait. You can eat to much.
You can and that is covered in his book. I will say however that if you are doing IF there is much less chance of gaining weight overeating on a keto based diet.
You know why they don’t have “Biggest Loser” reunions? Almost all of them gained the weight back—even more. Why did this happen? As he says in the video, their bodies adjusted.
How can you say this still? When I got fat for the first time I was eating normally but supplementing with Nestle Quik chocolate milk drinks at around 4 per day. Back then these were full fat and higher calories and so much better tasting than what we have today that it addicted me fully! In 6 months I put on 20 pounds from a skinny 16yr old. From there I ballooned up to a whopping 315 at my heaviest and can tell you the amount of food I was eating at that point was ridiculous! My food intake kept increasing as my weight did and then health issues popped up. I went Atkins and dropped 165 pounds within a year effortlessly.
Now as I lost all this weight I was frequenting low carb forums and believe what they said about ketosis being magical and wasting away calories. Then I found a video by the BBC where they were testing this theory after Atkins death and by the end of the video they found very little wasting calories, maybe like 20cal a day, but instead concluded that low carb works simply because it made you eat less.
And your insulin is low enough that the body can access the fat storage. Remember you can’t burn fat if your insulin is high. That is why fasting works.
If you were to read his work, you will find that IF in combination with reduced carb intake is the cornerstone of his research.
So, what I learned is that counting calories will be useless if you don’t let your insulin drop, coz the body will adapt and will decrease your metabolism instead. Hence, you will certainly reach plateau.
And once your insulin is low(normal) then your body will switch over to fat burning mode and still consume the exact amount of energy it needs. This is they key to weight loss.
counting calories will be ALWAYS useless, regardless what you do with your insulin
You learned well.
My personal experience is the opposite of what you are saying. The only time I’ve lost weight and kept it off is when I counted and reduced calories. I’ve done intermittent fasting and it works for a little while, then the weight loss stops and I regain the weight. I’m still trying to find the right balance, but I am reading your books to see if there is something more that will help.
If IF quits working, it is simply a matter of temporarily changing to a more aggressive fasting schedule. To each their own and if that works for you great. I will tell you IF compared to calorie counting is easier to understand, less difficult to implement, and has better long-term results as far as not regaining the weight. I would also say it is far easier to sustain in a maintenance role. You like calorie counting? No problem, combine it with IF. Why not both?
Yep.
Feast and Fast is the key 😊 -400lbs weightloss “the fasting methode” ( Fung) and doing Carnivore
