Gigantic error in our present thinking, about how we gain and lose weight (caloric theory). And it has to do with physics and the 1st law of thermodynamics. Which simply states . . . .
The total energy inside a closed system remains constant. . .
which basically interpreted means, if you eat 1000 kcal and burn 1000 kcal, you will not gain weight. This interpretation of the law is incorrect.
The law is correct . . . .but the application is incorrect . . .because . .
The 1st law of thermodynamics deals in physics and not in. . . physiology!
Allow us to simply explain . . . calories are a measurement of energy when a material is burned. For example, you burn a piece of wood and 1000 kcal of energy comes off it. And then you burn a steak and 1000 kcal of energy comes out of it. Inside your body one of the 2 is going to give you energy. The other is going to give you no energy at all . . . but it will give you a “splintering” case of hemorrhoids! Can you guess which is which? Of course you can . . .
Moral of the story is . . . calories do not matter - what a human body does with calories matters. And that my friends depends on your physiology (insulin). Because physiology dictates energy in humans, not physics . . .
We are human beings . . not pieces of wood!
