I'm an 18 year old female. Recently, I lost 22 pounds and while I'm happy with the results, I'm not happy with how I'm getting there. I'm 5' 3.5" and 110 pounds now. I run 1,000 calories on the treadmill (about 7 miles on a high incline) 5 days a week. I've been eating about 500 calories a day, if even that. I want to maintain my weight while trying to be more healthy about it. The problem is my metabolism, in that it's always been shit and it's probably even worse because in order to compensate for it's shittiness I've been semi-self starving. When I was at my highest weight (about 132 pounds), I was probably only eating about 1,200 calories a day and doing moderate exercise on a regular basis (I'm a fencer). I know that if I switch to a technically "healthy" diet of 1,800 calories, I'm going to gain a lot of weight. My mom has hypothyroidism and she's on medication for it and diabetes runs in my family, so I'm one of those people with a natural inclination to be "fat". I feel like there's no winning in my situation. If I try to be "healthy" with my diet and exercise, I will gain weight until I ultimately end up borderline overweight. I feel like if I go to a doctor about this, they'll dismiss me without treating my metabolism problem because I'm no longer overweight.
