The Claim
During resistance training, protein intake produces a greater increase in muscle hypertrophy compared to carbohydrate or fat intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When doing strength training, consuming more protein leads to greater muscle growth than consuming the same amount of calories from carbohydrates or fats.
See the scientific wording
Protein intake has a greater effect on muscle hypertrophy than carbohydrate or fat intake during resistance training.
When you eat protein, your body breaks it down into amino acids, which are used as building blocks to make new muscle proteins. During strength training, your muscles are stressed and need to repair and grow. More amino acids from protein intake help your muscles make more new protein than they break down, leading to bigger muscles over time.
What the research says
1 studyThis study found that eating more protein at breakfast helped middle-aged women build more muscle when they did strength training. It suggests protein is more important than other foods for growing muscle during workouts.
