The Claim
A higher protein intake of approximately 1.3 grams per kilogram of body weight combined with dairy consumption during a calorie deficit results in increased lean body mass.
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.
People who consume about 1.3 grams of protein per kilogram of body weight and include dairy in their diet while eating fewer calories than they burn gain more lean body mass than those who do not.
See the scientific wording
A higher protein intake (~1.3 g/kg) combined with dairy consumption during a calorie deficit promotes gains in lean body mass.
When a person eats more dairy protein and gets enough calcium while cutting calories, the amino acid leucine from the protein turns on a muscle-building switch in muscle cells, causing more muscle protein to be made. At the same time, calcium from dairy enters fat cells and stops them from storing fat while helping break down existing fat. This allows muscle to grow even when the body is in a calorie deficit.
What the research says
1 studyWhen overweight women ate more protein and more dairy while dieting and exercising, they gained muscle instead of losing it—even though they lost the same total weight as others. This shows that eating more protein and dairy helps you keep or build muscle while losing fat.
