well, I'm 142 lbs, 5'7", waist 30 inches, 19.
In javuary of this year, I was about 118. then I started doing some pushups and so forth and increaed my intake from like 1200 to 2000 (which is still pretty low for a 19 yr old who is faily active) . In like 3 months i i went up to 128, but there was plenty of fat storate even though i still wasn't eating a lot of fat cuz my body wasn't used to it.
it mid may, i started working out while taking in about 2600 calories. I did that for a while. It wasn't until early Augst that I got together with a friend and , with th ehelp of this board, put together a solid diet plan at about 3200 calories. Then, in September, I upped to about 4200 calories. In these past two months, I have gained very little fat (maybe 10-15% of the gain is fat), and I almost never deviate from the diet plan. However, it took months for my body to recover from the 1200 calories a day it was used to. (when i was anorexic, i would barely eat anything on some days, and over time my body starrted to maintain the weight with just 1200 caloreis; anything over that was directly stored because the body thought it would never get any more extra food again)
