To optimize physical results and muscle repair, especially with age, it is crucial to go beyond simple calorie counting and reach a specific threshold of essential amino acids through high-quality protein intake or targeted supplements.

The claim that protein is essential for tissue repair and cannot be stored like fats or carbohydrates is scientifically accurate (meta-analysis, Journal of the International Society of Sports Nutrition). It is also proven that anabolic sensitivity decreases with age, sometimes requiring higher protein quality or distribution (systematic review, Nutrients). The idea that carbohydrates and lipids are interchangeable as energy sources is a physiological simplification, though relevant in a general metabolic context. The argument regarding the necessity of amino acid supplements is more nuanced: while these products can help achieve a complete amino acid profile without caloric excess, research shows that a diverse diet generally provides these elements for healthy individuals. The superior efficacy of a specific supplement compared to a complete protein source (such as whey or eggs) is not consistently demonstrated in independent scientific literature. In summary, the need for protein is real, but the use of supplements remains a matter of convenience rather than an absolute biological necessity.
