Hmmmm yeah so the thing is, in the past 6 monthes or so I've lost about 55 pounds....and may or may not be anorexic, and might have thinner hair(which maybe a good sign I've lost too much hair)......so yeah I'm no longer restricting my diet, upping from 1500 calories a day, to atleast 2,000.....but I'm not even sure that enough. I'm concerned about my hair frankly......so yeah I'm 5'11'' and about 175ib 20 male. How many calories should I be eating a day? Alot of sites say, if I'm moderately active, I should have about 3,000 calories. but I'm not sure.
