BCAAs لـ Muscle Preservation During Weight Loss

B الأدلة تدعم ذلك تجربة عشوائية واحدة على الأقل، مع نتائج متسقة في معظمها.

Systematic review of 36 studies found BCAA supplementation during caloric restriction preserved lean body mass better than restriction alone. Observational study (n=4,429) found inverse association between BCAA intake and obesity (OR 0.66). Benefits are most pronounced when total protein intake is inadequate.
