How can I lose weight for dancing?

I really need to lose weight but I can't stop eating! I am dancing soon and I can't go up there the way I am. If anyone has an answer please tell me how!!!

Just eat more salads...and fruit...I lost weight and ate a lot of that...like fresh mangos and strawberries and grapes I ate so much...and lost weight....jsut change what you eat....

you know....someone once told me that it doesnt matter how you look but how you dance.....if you do great no one will care!!!!!!!!!!! but if you really want there is no problem with eating stuff low calorie and excersising more!

What I do to help me lose weight is to keep a rubber band on my arm and write my goal on the bottom of my rubber band and every time I want to eat something that I shouldnt my band reminded me not to........also any chance you get get up and walk around and move........I don't know it worked for me it might work for you.
