My advice - at least for right now, ignore the nutritional part of the program and just work on the working out portion. You are working out so hard and burning so many calories that if you just take a "common sense" approach to your diet (I have a bowl of cereal and a yogurt for breakfast, a "to-go" can of soup and a sandwich for lunch, a modest dinner, and fruit for snacks) you'll get your results. In fact, I for the most part blow off the diet on weekends just to make sure I can enjoy pop and other foods that I do like that if I completely eliminated would derail me. I've been through one cycle of P90X and I'm 1/3 of the way into phase 1 of cycle 2, and I've lost in excess of 25 lbs, and a lot more fat mass than that because I've put on a ton of muscle in the process.
Now, towards the end if you're looking to "fine tune" your body and get rid of the extra fat that's getting in the way of you looking ripped then you might want to adhere to the diet. But if you're far away from that anyway (like I am) following such a strict diet for that long will probably just derail you.
I would have to agree with this. A big reason why I have had success with this program is because I followed the nutrition plan. This program is just about being ripped, losing weight or looking good, it's about living a healthier life style. If you have success with a fitness program but lose all the advantages because you don't change your lifestyle, was it really worth it? You could say your going to stick with it somewhat, but seriously where does one draw the line? It can get dicey. Regardless of what your intentions are with the program, a healthy, well balanced diet is essential for success both during and beyond the program. So start developing those good habits now.
If your hungry, try spacing out your meals and eating more frequently as you experience hunger, that helped with me in dealing with the same problem. Also, you could try increasing you caloric intake. Even though it gives you a range in which to operate in, the book also says that if you feel like you need more or less calories then you should adjust accordingly. The most important thing is to listen to what your body tells you.
