A while back, I ended up starving off 15 pounds, even though my bmi had always been right at the low end of normal. I've since forced myself to eat more, and gained back about half of what i'd lost. I'm fairly normal-looking now, and I exercise a lot. My problem is, i'm counting calories to maintain my weight, and i'd really rather stop. I'm worried that if I do, i'll either lose weight or gain a lot, especially since I still eat irregularly, little during the day and the rest in the evening. What should I do?
