Go check out this dietitians web site calorie calculator. Fill the requirements as much as possible. I was amazed at how many calories it told me to eat for me to maintain. One thing that is screwy is the macro percentages, you don't have full flexability with it. Anyway check it out here:
my results were 4650 per day, I'm 205 about 12% at 6'2" medium frame. . . just interested in what others think, because those calculators are usually really low.
