What should I use as my regulatory diety..?

Different diets work for different people. Regardless of what you choose it has to be something you can stay on permanently. You can't just diet when you think your getting fat, as a dancer you have to maintain a consistently low level of bodyfat.

For me carbs are the problem. The only real carb heavy meal I eat is breakfast, I usually have a bowl of cereal or hot oatmeal. Then with lunch slightly less, usually just a sandwich with some whole wheat bread. For dinner almost none, a very small scoop of rice or vegetables with a small steak or chicken breast.
