The Claim
It is believed by some that BCAAs can help in weight loss by reducing appetite and increasing fat oxidation.
Origin
This myth often originates from extrapolations of studies on amino acid metabolism and anecdotal claims in fitness communities.
What Science Says
Research indicates that BCAAs alone have limited impact on weight loss. While some small studies suggest a potential role in appetite regulation, larger RCTs and meta-analyses have not supported significant effects on fat loss when compared to dietary interventions or other supplements.
Verdict
Partially True
