Even though eating more protein makes you burn more calories right after a meal, your body gets used to it over time — so after weeks, that extra calorie burn disappears.

Even though eating more protein every day makes you burn more calories at rest, it doesn’t make you burn more calories after meals over the long term—your body gets used to it.

Eating a meal with more protein makes your body burn more calories right after eating — but only if you’re not overweight; if you are, this calorie-burning boost doesn’t happen.

Chronic elevation of protein intake above optimal levels for muscle synthesis does not sustainably increase diet-induced thermogenesis, despite acute thermogenic effects.

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.

Eating more protein makes your body burn a bit more calories just to digest it, compared to eating less protein.
