nutrition plan p90x

Is the nutrition plan essential for P90X?
Hey,
I was wondering if the P90X nutrition plan was a MUST to follow. I work a ton and am never able to make any food because I am always working. I still watch what I eat, however. But, I was wondering if I were to not follow the nutrition plan they give everyday if it will impact the workouts greatly.
Thanks
Try preparing a bunch of your meals in advance. You can grill up a weeks worth of chicken breasts, make several turkey sandwiches, bag a weeks supply of veggies and nuts for snacks, etc.
Tony Horton says to eat fruits, veggies, lean protein, good fats and whole grains. That is the basis of the meal plan.
Sticking close to the meal plan is preferred, but not absolutely necessary. Eating clean foods is vital.
