As we age, muscle becomes less responsive to smaller doses of dietary protein. Leucine can help strengthen that anabolic signal, but BCAAs are not a replacement for complete protein, and the popular “30 minutes before a meal” strategy is more plausible than proven.
Long stretches of sitting can work against muscle and metabolic health. Short activity snacks, from chair squats to quick walks, may help break up sedentary time and support better training results.
More protein is not always better, and too little will not cut it either. A moderate, balanced intake can support muscle without turning nutrition into a numbers obsession.
