The Claim
In young women with overweight, a high-protein intake of 1.6 g/kg/day during calorie restriction and resistance training preserves or increases fat-free mass, while a regular protein intake of 0.8 g/kg/day does not, demonstrating that protein dose is a critical factor in muscle retention during weight loss.
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.
Young women with overweight who consume 1.6 grams of protein per kilogram of body weight per day while dieting and lifting weights maintain or gain muscle mass, while those who consume 0.8 grams per kilogram do not.
See the scientific wording
In young women with overweight, high-protein intake (1.6 g/kg/day) during calorie restriction and resistance training likely preserves or increases fat-free mass, whereas regular protein intake (0.8 g/kg/day) does not, indicating protein dose is a critical factor in muscle retention during weight loss.
When a person eats more protein while lifting weights and eating fewer calories, the extra amino acids from the protein turn on a cellular switch that tells muscles to build more protein, preventing muscle loss and even increasing muscle mass.
What the research says
1 studyWhen overweight women diet and lift weights, eating more protein (1.6g per kg of body weight) helps them gain or keep muscle, while eating less protein doesn’t. The study proved this by showing muscle went up only in the high-protein groups.
