I am seeing a lot of different idea in terms of how many calories per pound of muscle are there. But i will say, for every source that says it is around 5-6, there is about 300 sources that say it is 30-50. The statement about how if it were 50x80=4000 and the guy is fat....he probably wouldn't be fat if he ate nothing that was processed besides supplements. I think unless you are over 30, you should be able to consume at least 3500 natural calories, even though genetics will play a role.
You really do not need to know your BMR anyways because lets face it....the only time you are inactive is when you're sleeping.
