If you want to get big like a bodybuilder, that will require unhealthy
eating such as
eating too much food and too much protein, but it does work to build more
muscle mass. Too much protein is very hard on the kidneys and other parts of the body, and too much food is hard on the digestive system and the internal organs. No natural living human needs muscle mass for strength -- hunter gatherers are very strong, farmers are very strong, but they don't necessarily have big muscles.
