The Study
Effects of Protein Intake Beyond Habitual Intakes Associated With Resistance Training on Metabolic Syndrome-Related Parameters, Isokinetic Strength, and Body Composition in Older Women.
This study shows that older women who took extra protein while doing strength training tended to gain more muscle and lose more belly fat than those who didn’t. But we can’t be sure the protein caused the difference because we don’t know for sure how the study picked who got protein — it might not have been completely fair or random.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Older women who drank a protein shake every day while doing strength training got stronger and healthier faster than those who didn’t.
