I just got my Insanity in the mail, and I’m wondering what kind of results to expect.

I’m 5′9" and I weigh 145lbs. (this puts my BMI at 21.4) I very rarely exercise (until now), but I’m not obese either so I’d say I have a pretty good metabolism. I don’t plan on following the diet plan (I want to eat what I want), and I’m 17.

If I follow the Insanity workout for the full 63 days, what do you predict my results will yield?

ALSO:
About my diet: I don’t really watch what I eat, but I’m not scarfing down a whole bag of chips myself either. I usually eat healthy things (I love salads). Usually when I snack its on some pretzels or some of those cheese crackers.

Really the only unhealthy thing about my diet is that I LOVE soda. I mean LOVE it. I drink a few cans a day.
Side note: I’m not looking to get shredded, I’m just looking to tone a little. I know I couldn’t get ripped unless I strictly controlled my diet, and I don’t know if i’m ready to do that.
