How do I decide on a goal weight? For the past 7 years it's just been constant weight gain...I lost 30 pounds while housekeeping but I gained that back and more and since gaining all this weight I've never done anything to change my ways until these past four weeks.

When I was 18 I was 110 pounds and yes I was very healthy. But I am not 18 anymore, and I am not sure if just because I looked and felt great at 110 once I'd look that good at that weight now. I don't know when enough is enough. I do know I want a flat belly with my hip bones protruding, at least half the size of my thighs now, a distinct jawline, no neck fat, thin fingers, and a small butt. Should I just aim for that and see what happens? I am confused and I really don't know.

Oh btw, if I lose 6 pounds a week, I'll lose 100 pounds in 4 months!
