Answer 2

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer࿐}}}}}}$

Protein contains 4 calories per gram, but a large part of these protein calories is lost as heat when it's metabolized by the body. The thermic effect of food is a measure of how much different foods increase energy expenditure, due to the energy required to digest, absorb and metabolize the nutrients.
