Your body burns the most calories after eating protein, fewer after carbs, and the least after fat — which is why high-protein diets are often used for weight loss.

Similar Assertions

Eating a fatty meal doesn’t make your body burn many extra calories, and your brown fat doesn’t seem to play any role in that process.

84%

Eating a high-protein meal makes your body burn more calories afterward than eating carbs or fat — but this doesn’t depend on how active your brown fat is.

82%

Eating a high-protein meal makes your body burn more calories afterward than eating carbs or fat, but this boost isn't linked to your brown fat — something else is responsible.

Diet-induced thermogenesis is significantly higher for dietary protein compared to carbohydrates and fats due to the greater metabolic cost of protein absorption, transport, and amino acid metabolism.

Diet-induced thermogenesis is significantly higher for dietary protein compared to carbohydrates and fats due to the energetic cost of protein absorption, metabolism, and amino acid synthesis.
