As far as I can tell all fitness blogs say you have to eat lots of protein to build muscle (with exercise). But why protein specifically? If excess calories from any macro can be converted to fat by the body, why do we need protein to build muscle? Couldn’t the body just use excess from any macro combined with weight lifting exercises to build muscle ?
In: Biology
Your body does not use the same resources for using muscles and building muscles. The former can be obtained from fat storage. The latter needs specialized resources (proteins).
