The Claim
HMB supplementation has no significant effect on fat mass in athletes, with a mean difference of −0.33 ± 0.23 kg (95% CI: −0.96 to 0.31 kg; p = 0.22) across five studies involving 128 participants.
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.
Taking HMB supplements does not lead to a meaningful change in fat mass among athletes, based on data from multiple studies combining 128 participants.

What the research says
1 studyStudy: Does HMB Enhance Body Composition in Athletes? A Systematic Review and Meta-analysis
This study looked at whether HMB supplements help athletes lose fat and found no real change — the tiny amount of fat lost wasn’t enough to be meaningful. So, HMB doesn’t seem to help with fat loss in athletes.
