So....this will either really work for you or really NOT. When I was a dancer, we dieted a lot, needless to say. The only way I found that I was able to diet for long periods when necessary was to always include the 220 (or whatever it is) calories of a plain Hershey bar, every night, as part of the total daily allowance of food. Otherwise I'd go off the diet eventually and go totally bonkers on chocolate when I did--it was like, I'd been holding my breath all that time and so I had to gasp in great gulps of chocolate to recover! Once I figured out the Hershey-bar-a-day thing, it was way easier to stay on a diet. I know that doesn't work for everyone, and the next person will probably say, I can only diet if I totally banish chocolate. But it works for me.
