Well, I always hoped that the rumors were true – that gaining muscle mass would increase one’s resting metabolism. How many times have you heard fitness gurus tell you that if you bulk up with muscle you burn more calories even when you’re sitting around, watching TV?
Unfortunately, the truth is that even the most impressive muscle gains result in only a tiny increase in resting metabolic rate. In one case I recall a man who lost ~40 lbs of fat and gained ~20 lbs of muscle. His metabolism increased by a mere 50 calories/day.
In my experience, metabolism seems to be more a factor of nature rather than nurture. You’re born with a certain internal engine – and not much changes that (at a given body weight). However, exercise burns calories – and that can lead to weight loss, etc. It’s just that the baseline metabolism doesn’t change all that much.
Stay tuned for my next blog entry where I’ll explain why metabolism may be linked to diet failure.
