P90x is a good program that can help you to lose those fats. Make sure that you stick to it until the end. Try as much to follow the program to the T and you'll see results.

About the food, doesn't matter if you are on P90x, strength training, or bodybuilding, if you want to eat healthy, you had to cook them by yourself at least for me. Sure it is time consuming but you can always prepare your food for the day in the morning.
