I know that teenage girls are in danger of developing a bad self image and creating all sorts of problems, physical, psychological and emotional because they get the idea they are not acceptable - there are depressed women on this site that started that way
now is the time to AVOID developing these problems
guys get it too
I started my yoyo dieting when I was 14 - it affected my whole life
if I had NEVER dieted I would not be as huge as I am now - it messes with yr metabolism
I might observe in passing that a 14 year old is still growing and I cannot think of any scenario where it is good for one to lose 12 pounds quickly
I have a super fast metabolism and have never really cared about what I eat (never REALLY had a need to, I don't gain weight.). When I get sick, I loose a lotof weight, and my equilibrium gets all jacked up, but usually I am 'as sturdy as a horse'.
I try not to let the world get me down, and it usually works. Until the annual nervous break down of all emotions that I have stored up inside of me errupt.
