True or False? Protein has the highest thermic effect compared to other energy-yielding nutrients.

Protein does indeed have the highest thermic effect when compared to other macronutrients, such as carbohydrates and fats. The thermic effect of food (TEF) refers to the energy expenditure above the basal metabolic rate due to the cost of processing food for use and storage.

When the body metabolizes protein, it requires significantly more energy to break down and utilize compared to carbs and fats. This increased energy expenditure associated with protein digestion, absorption, and transportation results in a higher thermic effect, which can account for approximately 20-30% of the calories consumed from protein.

In contrast, carbohydrates and fats have lower thermic effects, contributing about 5-10% and 0-3%, respectively. This efficiency of protein in inducing thermogenesis plays a role in weight management and can enhance the overall metabolic rate, making it an important nutrient in weight loss and maintenance strategies.

Therefore, stating that protein has the highest thermic effect compared to other energy-yielding nutrients is accurate.
