1 gram of carbs equals 4 calories.
1 gram of protein equals 4 calories.
When metabolized, however,
carbohydrates yield 5x the ATP proteins do. 1 gram of carbs is 5x as "rich in energy" as 1 gram of proteins. In spite of them being billed as equal.
A tablespoon of sugar yields about as much energy as a pound of chicken breast.
Then we go into fat. People think fat makes them fat. The truth is, ingested fat can not be turned into bodyfat directly. It is way easier for the body to turn carbs into fat than it is to turn fat into fat.
"Diet" products that extract fat from milk products, like yoghurt, and replace them with sugar, which makes the product less calorically dense, nominally, literally makes people more fat - AND is billed as a diet alternative.
Everything. the. media. says. is. wrong.
Everything.
And this isn't arcane knowledge acquired from some hermit. Its literally on wikipedia. One click away. Google ATP, or adenosinetriphosphate, and read the whole page. you will know more about diet than most dieticians.
When I talked to my physician about these things, initially, they didnt know those basic facts either. All the knowledge we've got about how to lose weight is buried and ignored by bullshit.
Simple facts that, if applied, make people lose weight. Caloric restriction is bs. Carb restriction is key. You can literally eat until your stomach hurts all day long and lose weight. Its what Ive done.
