Question

Quizplus · Accepted Answer

The statement is false. On a mass basis, carbohydrates provide 4 kcal/g, while fats provide 9 kcal/g, making fats more efficient sources of energy. However, protein metabolism is not as efficient as carbohydrate or fat metabolism, as protein has additional functions in the body such as building and repairing tissues. In fact, metabolizing protein for energy can have negative effects on muscle mass and overall health.
