Perhaps I just don't understand what "metabolic rate" means. My body is a metabolic zero-sum game, unless I'm gaining or losing weight. What comes in as food goes out as heat or mechanical work. I suppose a higher heat output could be achieved at constant temperature by sweating more. A larger person (more skin) could of course generate more heat, but the energy has to come from eating more food or being less active.

Do you simply mean that I was gaining weight at birth, adolescence, and teen years? I could agree with that.

"What comes in as food goes out as heat or mechanical work." Or out as undigested food waste. Don't have an answer for you on metabolic rate, just adding the third way food calories can leave your body.
