i thought you werent interested in doing p90x?
hows the progress from your first attempts at cutting weight coming along?
the diet isnt needed, you will obviously always burn fat as long as you burn more calories than you take in, but as far as nutrition into your body, the better the foods you eat, the better results you will get. the more natural your diet, the easier it will be for you to replenish your body with the good nutrition and vitamins it is missing from your normal everyday foods. therefore, your body will appreciate the good nutrition and your mind will be more free and brain process will be better, and you will feel more alive the more "good" food you eat. make your own smoothies from certified organic fruits, and eat potatoes. even though they have plenty of carbs, carbs are your best friend if you use them right. and potatoes have important vitamins as well.
uhm.. no i dont have a copy of p90x. lol.
honestly, if you just go on a nice jog everyday, eat right, drink ice water (your body burns calories when it heats up the super cold water) and lift (doesnt have to be the body builder type of lifting) and use the stairmaster ( stairmaster will destroy fat alone ). as long as your as motivated for that as p90x, your results will be pretty similar.
you will burn plenty of calories. start your day off with a cup o joe (coffee) a jog, and 20-40 pushups. that will get your body's motabolism kicked into high gear throughout the day. no need to spend money on that kind of stuff.
