The Claim

A high-protein diet, when combined with resistance training, is associated with greater muscle hypertrophy and strength gains than resistance training alone, likely due to the provision of amino acids that support elevated muscle protein synthesis.

In plain English

If you lift weights and eat more protein, you’ll likely build bigger muscles and get stronger than if you just lift weights without eating extra protein.

What the research says

1 study
  1. Study: Strength Through Science: A Comprehensive Look at Resistance Training and Protein Intake in Muscle Development

    This study found that when people lift weights and eat more protein, they build more muscle and get stronger than when they just lift weights alone — because protein gives their muscles the building blocks they need to grow.
