I wonder if this could partly explain why some people gain muscle easily without eating more when lifting regularly. Common wisdom says you have to eat more to make up for the extra energy expenditure, or otherwise your muscle growth will be limited. But I'm just not that hungry. Yet not purposefully supplementing with more food during training regimens never seemed to hinder my muscle growth. Then again, I don't know that. Maybe I would've gained even _more_ muscle if I'd been eating more. Anecdotally, it just seemed like muscle has come on pretty easily regardless of how much I eat. Could the body simply be redirecting more of my calories to growing muscle during these periods while keeping the total expenditure the same?
