The Claim

In healthy young men, diet-induced thermogenesis following a protein-rich meal is higher than following a carbohydrate-rich or fat-rich meal, with measured values of 6.44%, 3.49%, and 2.32% of ingested energy, respectively, and diet-induced thermogenesis shows no significant association with brown adipose tissue activity.

In plain English

In healthy young men, eating a high-protein meal causes a higher increase in energy expenditure after eating compared to eating high-carbohydrate or high-fat meals, with specific percentages of 6.44%, 3.49%, and 2.32% of the meal's energy, respectively; this increase in energy expenditure is not linked to the activity of brown fat.

See the scientific wording

In healthy young men, diet-induced thermogenesis after a protein-rich meal is higher than after a carbohydrate- or fat-rich meal (6.44% vs. 3.49% vs. 2.32% of ingested energy), but shows no significant association with brown adipose tissue activity.

Why this might work

When you eat a protein-rich meal, your liver breaks down the amino acids from the protein, and the process of removing nitrogen from them and turning it into urea uses a lot of energy, which generates heat and raises your body's calorie burn.

  1. Study: Brown fat-associated postprandial thermogenesis in humans: Different effects of isocaloric meals rich in carbohydrate, fat, and protein

    Eating a high-protein meal makes your body burn more calories afterward than eating carbs or fat, and this effect doesn’t depend on how active your brown fat is — and the study proves it. Brown fat only helps burn extra calories after eating carbs, not after protein or fat.
