Miller PE, Alexander DD, Perez V
Published in Journal of the American College of Nutrition
Methodology
Meta-analysis of 14 randomised controlled trials of whey protein supplementation with or without resistance exercise.
Key Findings
Whey protein combined with resistance exercise reduced body weight and fat mass and increased lean body mass; whey alone had minimal effect on body composition.
Conclusions
Whey protein influences body composition mainly when combined with resistance training rather than as a standalone supplement.
Limitations
Small trials, short follow-up, industry involvement in several studies.
Supplements Studied
Whey protein combined with resistance exercise reduced body weight and fat mass and increased lean body mass; whey alone had minimal effect.
Outcomes Measured
