OK let's ignore protein for a second. You're saying that if you eat the same number of calories, but as fat instead of carbs, your body will store less of it. i.e. that the human body is much more efficient at extracting energy from carbohydrates than it is from dietary fat, i.e. more of the energy from dietary fat is wasted. Macronutrient choice cannot affect the amount of work that your body does, only what percentage of the calories are wasted (inefficiency).
On the face of it this makes no sense because fat is such a good energy source that it's what our bodies use to store energy, so why would our bodies have problems extracting energy from dietary fat?
- DiThi 9y agoI didn't say that our bodies extract less energy from fat. It stores less energy as fat. Fat storage mode is stimulated by insulin, which is stimulated by glucose or by lack of sodium. Insulin brings other health problems in addition to weight gain.
- toasterlovin 9y agoSee my other response, but the theory is that high fat diets make more energy evailablw for use, rather than storing it in adipose (fat) tissue. This makes someone more energetic, which is how a high fat diet can result in weight loss at the same calorie intake, but still have the energy balance equation work out.
