Alex,
you have got the be the #1 dumbest bastard in the world. Every single time you post you reastablish yourself as the most ignorant person on these boards. You need to leave. seriously its people like you that promote anorexia and other eating disorders. 107lb at the height is defenitly underweight, if you don't realize that, then you have problems that need to be addressed quickly. If youre going to respond with crap like that then you need to go to some ballet discussion boards.
rez, follow belials advice. I think you need to stop the low cal low carb dieting for a while and put on some muscle. Just continue to eat clean, but more. If you do your body will probably be more able to lose some fat.
hope that helps.
