One thing that is commonly promoted by low-carb gurus is the notion that
“YOU NEED TO EAT FAT IN ORDER TO BURN FAT”
In other words, in contrast to eating carbs, eating dietary fat “stimulates your body to burn off body fat.”
So where did this idea come from? And is there any truth to it?
To put this really simply:
THEY MADE IT UP.
There is absolutely no truth to this whatsoever. It is complete and utter BS that someone just made up one day and has been endlessly promoted by low-carbers since then as if it were a fact, while none of these people promoting it have bothered to look at the research.
First let me acknowledge the part of all this nonsense that’s actually true: Becoming fat-adapted so that you’re burning predominately fat rather than carbohydrate for fuel is actually a real thing.
So that part is actually true. It is indeed possible to train your body to rely primarily on fat rather than carbs for fuel.
And, it’s actually very simple to do it: All you have to do is eat a low carb, high fat diet–remove carbohydrate calories from your diet and replace them with fat calories.
Then … BOOM! After a few weeks, you are now fat adapted, and your body will primarily rely on fats rather than carbs for fuel.
Now that you’ve switched out a large portion of carbohydrate calories for fat calories and made yourself into a “fat burner,” you can expect lots of fat loss, right?
As long as TOTAL CALORIES haven’t changed, high-carb, low-fat diets and low-carb, high-fat diets cause—get ready for it—absolutely no difference in fat loss. None.
In other words, you’re only burning more fat because you’re EATING more fat–and less carbs. You’re burning the fat you’re EATING, not body fat.
This has been proven over and over again by countless studies.
There is absolutely ZERO science to indicate that eating a higher fat diet makes you lose body fat faster. This whole notion is just utter BS.
P.S. By the way, if you decide to ADD in fat to your normal diet thinking that it will stimulate your body to burn off body fat, you’re in for a little surprise, because the only thing that will happen is you’ll get FATTER.
