What does this rating mean?
Limited, mixed or hard-to-translate evidence. Useful as direction, not as a rule.
Findings
The effect of beef protein as a supplement on body composition and performance.
Who this applies to
People following an exercise training programme; age, sex and training level are not given in the abstract.
Size of the research
Seven randomised trials with 270 participants in total.
What to keep in mind
Only a few trials were included. The lean mass difference versus no supplement was small and only just statistically significant. Arm strength and fat mass showed no clear change.
Practical conclusion for REZA
Supports the line that protein source matters less than total amount.
