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.
What the Evidence Shows
We analyzed two assertions about diet-induced thermogenesis and protein, and what we’ve found so far leans toward the idea that protein raises energy expenditure more than carbs or fats because of the metabolic effort needed to process it [1]. Both assertions point to the same mechanism — the...
