Proteins are the most important source of food energy.

Question

BlackTom AI · Accepted Answer

Consider the statement carefully: 'Proteins are the most important source of food energy.'
Option 1 (True): This is misleading because, while proteins can be used for energy if carbohydrate supplies are low, they are not the body's primary or most efficient energy source. Proteins mainly serve structural and functional roles (growth, tissue repair, enzymes, hormones), not as the main fuel. Using protein for energy also risks loss of lean body tissue and impairment of essential protein functions.
Option 2 (False): This is correct. Carbohydrates and fats provide the majority of usable energy in the diet. Carbohydrates are quickly mobilized and fats offer a high energy yield per gram, making them the dominant energy sources under most normal conditions. Proteins contribute a smaller portion of daily energy—typically only when carbs and fats are insufficient—and their primary role remains protein synthesis and metabolic functions, not energy provision. Therefore the statement is not accurate.
