Does Muscle Size Increase Fat Loss?

    I know that the more muscle you have, the more fat gets burned but does the size of your muscle have anything to the fat burn rate? I've seen super lean guys who are muscular but not bulky and they don't have much fat on them. I've also seen guys who are bulky/stocky and have fairly little fat on them as well. Thanks for any feedback!

    It does to some extent. Muscle preferentially burns fat, and like any other part of your body, it burns calories even at rest. It's probably somewhere between 4-10 calories per pound of extra muscle per day without additional activity.

    Muscle isn't very metabolically active at rest, so, the differences are going to be most noticeable when you start getting active. If you have an extra 30lbs of muscle and you're doing cardio, a much higher % of calories burned will likely come from fat with the same amount of cardio simply due to the extra demand.

    So it's definitely easier for large guys to lean out. I put on 25lbs of muscle, and now if I get lazy and stop eating enough, I feel like the fat just melts. It's a pretty big difference.

    If you're referring to the size of the muscle itself, I'm not really sure. Muscle can get stronger without getting much bigger, or it can get bigger without getting too much stronger depending on how you train. (Most people see both to some degree) I think it'd be pointless to debate which burns more calories per unit of muscle volume since either way, you're going to burn more fat.

    Short answer: Yes.

    You weigh more in lean tissue, so when you mix that with your fat tissue, that leads to a higher metabolism.

    Meaning that at 265 lbs with probably 17% body fat, I burn more calories than someone who weighs 200 lbs with 17% body fat. You see what I mean?
