"The next fuel that gets burned is fat. All human beings have a certain percentage of body weight that is fat. From an evolutionary stand point this is advantageous. During times of drought or famine there were not enough crops to provide adequate carbohydrates, and thus humans survived by “burning” their fat stores. In biochemical terms, fat is nothing more than long chains of carbon atoms linked together. Suffice it to say that it is the carbon in the fat that gets utilized to form energy that your muscles and other body tissues use. "
"The third and final fuel is protein. The body rarely burns protein as its sole fuel source, and when it does it is usually under conditions of starvation. Interestingly, when no carbohydrate is present in the diet, the body will use the amino acid backbones of protein to form glucose (a carbohydrate) in order to supply the brain with adequate energy.

不錯你很認真 但你這篇寫得很清楚了It was once thought that protein provided the energy that athletes used during exercise. This was the basis behind the “steak-and-eggs” breakfast prior to an athletic event.
而你說的那個順序是一般人基礎代謝的順序 如果你要跳鄭多燕 那ok 這也沒錯
如果你要練猛男(運運員) 體指率已經夠低了 吃的也很少油酯(不要吃雞腿) 血液中游離脂肪酸很少 那就是protein provided the energy that athletes used during exercise
