So does protein really burn more calories during digestion than carbs and fats? If so, what's the difference per 100 calories?
It is interesting to note that meats subtract roughly 25% calories due to energy required to break them down, yet it's carbs that ramp up the metablolism....I've always found this odd
It is because protein is not fully oxidized like it is in a bomb calorimeter. If it were, we would excrete nitrate instead of compounds like urea.
Yes. You really only get 3.2 calories per gram from ingestion, not 4 like is usually claimed.
Incorrect. That is assuming 100% of the protein you use goes to gluconeogenesis. Which it is not.
The weighted average is still 4.
