The Claim

Does eating more protein every day boost your resting metabolism over time?

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Eating more protein every day for weeks or months makes your body burn more calories even when you’re resting, which might help prevent slow weight gain over time.

See the scientific wording

Chronic consumption of higher-protein diets (≥15% greater energy from protein) increases total daily energy expenditure by 29% (SMD: 0.29; 95% CI: 0.10, 0.48) and resting energy expenditure by 18% (SMD: 0.18; 95% CI: 0.01, 0.35) in healthy adults, independent of weight loss, indicating a sustained metabolic adaptation to prolonged protein intake.

What the research says

2 studies

  1. Study: Effects of Varying Protein Amounts and Types on Diet-Induced Thermogenesis: A Systematic Review and Meta-Analysis

    This study found that eating more protein over time makes your body burn more calories every day—even if you don’t lose weight—exactly what the claim says.

  2. Study: Effects of Varying Protein Amounts and Types on Diet-Induced Thermogenesis: A Systematic Review and Meta-Analysis

    This study found that eating more protein over a long time makes your body burn more calories at rest and throughout the day — just like the claim says. The numbers match exactly, so it supports the idea that high-protein diets boost metabolism.
