Summary

This study looked at whether getting protein from whole food (lean red meat) is better than from a supplement (whey protein) for building muscle during resistance training. 81 healthy adults did a 12-week exercise program and had either lean red meat, whey protein, or a placebo drink after each session. Researchers measured changes in muscle strength and body composition to see if protein source matters.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: lean red meat, whey protein, or maltodextrin placebo
What this could lead to: If it works, this could show that whole food protein like lean red meat is just as good as supplements for building muscle with exercise.
What could go wrong: This is a small, completed study in healthy young adults, so results may not apply to older people or those with health conditions. It also does not test any disease treatment.
