5’11", 170 lbs, my RMR is 1840, which I got by averaging the results from 4 or 5 BMR calculators. I’m a college kid, and I walk probably 3 miles a day around campus, moderately active in general. The calculators all say maintenance would be about 2700-2900 for me. My bwt x 18 is 2880, which fits right in with that.
And 2800 has been about right for me these last few weeks. I’m eating about 3200 right now, and have been gaining muscle and strength while staying relatively lean. So far I’m up 12 lbs in 5 weeks, I’m guessing ~3-4 lbs is fat. hooray for newbie gains!
