How can nutrition affect only one body part?
I have been searching the form trying to find ideas as to why my chest is not growing. One piece of advice I keep seeing is people saying to “eat more”. They give this advice even if the poster asking for advice claims that the rest of their body parts are growing or gain strength just fine. Assuming that the poster is telling the truth about the rest of their body parts, why would improper nutrition only cause one part of the body to lag behind the others?
