Why protein makes you burn more calories — but only if you're not overweight
Effects of Varying Protein Amounts and Types on Diet-Induced Thermogenesis: A Systematic Review and Meta-Analysis
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
Eating more protein makes your body burn more energy after meals, but this only works if you have a normal weight. Over time, your body gets used to it and stops burning extra calories from protein — but still burns more overall.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

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.
Chronic elevation of protein intake beyond the threshold required for maximal muscle protein synthesis does not sustainably increase diet-induced thermogenesis or total daily energy expenditure.
Eating more protein every day for weeks or months makes your body burn more calories even when you’re resting — even if you don’t lose weight.
Whether you get your protein from chicken, tofu, milk, or fish, it doesn’t make your body burn more calories — the amount of protein matters more than the source.
