Burn fat fast by controlling insulin. Dr. Jason Fung explains why calories in vs. calories out isn’t nearly as important as controlling insulin when it comes to burning fat.
Insulin spikes turn off fat burning. And insulin spikes cause leptin resistance so the “I’m full” signals don’t easily reach your brain.
The simple solution to get your body to burn fat fat is to reduce your intake of refined carbohydrates. During the refining process fiber and nutrients are removed. This allows for rapid digestion and assimilation of sugars into the blood stream. High levels of blood sugar mean insulin levels spike upward to try to control blood sugar.
Numerous studies have shown that diets high in refined carbs may be associated with excess belly fat.
You need to greatly reduce your intake of refined carbohydrates if you to to burn fat fast to see your abs.
Most people want to burn fat fast. But, what happens when you eat is that insulin goes up. And insulin basically is the hormone that tells your body to store fat, not burn fat fast.
Insulin stops your body from burning fat. When you eat, you start to store some of the sugar and store some of the fat. Carbohydrates get turned into glycogen in the liver. Basically, glycogen is a chain of glucose molecules used for storage. And when you have too much glycogen , then your liver produces lipids [fats] and your body stores fat.
How to Burn Fat Fast
So when you don’t eat, your insulin levels fall. And that’s a signal to start pulling some of that stored energy out. So you’re gonna start by pulling some of the stored glycogen energy out from the cells and liver. And then you’re gonna access some energy from the stored fat. This is the best way to burn fat fast.
Refrigerator and Freezer for Energy Storage
So you can think of the glycogen like a refrigerator. You can put food energy in easily and you can take food energy out easily. Right. It’s just food energy.
And the [stored] fat is more like your freezer. You can store more of it, but it’s in your basement. It’s hard to get to. It’s the same idea.
You have two storage forms of energy. The refrigerator, though, has a limited capacity. So, if you consume too much food you have no choice but to put it [as fat] in your freezer.
The body doesn’t have some giant vat of calories, right. You can store sugar; you can store fat. There are two places in the body where you can store food. Your calories go into your fridge and calories go out from the fridge.
Insulin Does Not Allow You to Burn Fat Fast
But there’s a third thing that you have to consider. And that is how much food goes back and forth between the freezer and the fridge. And the question is, “What’s controlling this?” And it turns out that the main player is insulin.
Insulin inhibits lipolysis [the breakdown of fats]. What that means is it stops you from getting the fat out. So if you have a lot of insulin, then you can’t get the food [fat] back out this way. So, normally, if you eat a huge meal your insulin is high. It’s going to tell the body to move all the storage in this way [into the freezer]. and that’s the problem.
Insulin Resistance Keeps Insulin Levels High
So, if you have a lot of insulin resistance, which keeps your insulin levels very high, it’s like that freezer is kind of locked away in the basement behind the locked steel bar. You can’t get at it.
Lets Try a Diet to Lose Weight
So what happens now when you start reducing your calories? If you start reducing your calories in, what your body is simply going to do is reduce the calories out [by reducing your metabolism]. That’s what it does because it’s not gonna keep losing weight until you die. That’s just ridiculous.
If you’re not affecting the insulin, you can’t get at that fat to burn fat fast. You’re just gonna reduce your calories out.
