I'm cutting back on the poison

The past few months I've been eating a lot of pastries and fast food, but I'm tired of putting all that poison into my body so I'm going to try and cut back a little at a time until I'm off it for good. I may not be particularly over weight, but I'm not exactly what you will call healthy either. I plan to be off of the stuff by the holidays, and by that I mean the holidays after thanksgiving. Nobody can go thanksgiving without some form of pastry. Unless you don't live in America, then it's fairly easy.
