Muscle burning 50 calories a day is a myth. Gaining 20 pounds of muscle adds 80-100 calories to your RMR for a typical person: http://articles.latimes.com/2011/may/16/health/la-he-fitness....

Yep. It's muscle recovery that is very calorically expensive. Those who have lifted or lift can probably attest to that crazy post workout appetite.

Thanks for the correction. I will point out that the article does indicate that there is some type of difference, so I would still think that such a loss would have some sort of impact (though obviously not ~400-500 calories worth).
