Macro partitioning

BCAA supplementation combined with resistance training significantly reduces BMI in young women, whereas meat protein supplementation results in significantly higher final BMI compared to BCAAs.

If you are a young woman doing resistance training, BCAA supplementation might help lower your BMI more effectively than meat protein supplements, though muscle mass gains were not significantly different across groups. Ensure you are consuming enough total protein (approx 1.4g/kg) and training consistently.

The results showed that the supplementation with BCAAs presented a significant decrease (p < 0.05) on the BMI in this group... The BMI of the group supplemented with meat proteins was statistically higher (22.06 kg/m2) than that the group supplemented with BCAAs (19.4 kg/m2) (p < 0.05).
