First time diet advice

[MSNate]

I wasnt sure how to search this and get the disired answer so hopefully somebody can help me out. Im 6' 1" 190 lbs. roughly 11 percent bodyfat. Ive decided to do my first natural comp this year and am slightly concerned about dieting because Ive always been naturally lean and haven't had to worry about it in the past. Im very familiar with what to do but I want to give myself a little extra time just to be safe. My question is if I get lean enough early enough what would then be the protocol on eating. Do I go back to normal maintenance or figure a new maintenance based on the lower weight and bodyfat. I just want to be as prepared as possible. Thanks
