Hi, 1800 is to keep your current weight. To lose about 1 lb /week while doing P90X you need 1,200. Do not go below 1,200 or you will begin storing fat and losing muscle.
By the way we are starting a new P90X BootCamp this next week, but you can stop by now and get your questions answered and for motivation and inspiration.
