Glad you bumped this, it gives me a chance to talk about something I was told last night by one of my fellow dancers.
She's always had trouble sticking to a healthy diet, but a month ago she adopted the mindset that what you should focus on is what your body needs. So that what you're thinking of when you go to make a meal, buy groceries, etc., is how many veggies, how many fruits, what nutrients, etc., you haven't had that day and would need. She's stayed easily on this path for a month and hasn't strayed.
I've taken it for my own philosophy and hope I can stick with it as well.
