This is something I’ve always wondered. It seems like guys at higher bodyweights can just get away with eating less cleanly, yet still preferentially add muscle rather than fat. I suppose if your maintenance is 4000kcal, a large pizza really won’t set you back that far, versus someone with say a 2000kcal maintenance level.
So I guess my question is: does some critical threshold of muscle mass to height exist where the body is simply able to send the calories “where they need to go?” As in, is there some physiological change that happens at some point where the body can just handle excess calories in a better manner? It seems like there’s sticking point of around 10 - 12% body fat for guys who are merely “normal” sized, where the huge guys seem to be able to lean out more easily while still retaining significant muscle mass. Yet when they bulk, they seem to get less sloppy. Hanging around this site, it seems like bigger really is better - the more lean muscle mass you have to work with, the better of you’ll be in the long run.
