I confused a fatty by modifying my diet before it became a problem. I've been partaking in soda more than I used to. I noticed I was heading towards a 22 BMI so as much as I didn't want to do it I limited my soda intake. I usually had Pepsi at lunch but yesterday at work I had a bottle of water. Since the Pepsi is sort of my trademark (I think it's delicious) one of my coworkers mentioned it. I said, "Yeah, I was packing on the pounds so I cut back."  My hambeast co-worker, who is about my height and probably weighs 250, snorted, "But you're so skinny." I replied, "Not really, I'm average. And I'd like to keep it that way or maybe even get smaller."  She said again, "But you're skinny, you don't have to worry about that." I tried once more, "Yes, but if I keep gaining weight I'll have to worry about it. I'd rather cut back now and only have to shed a few pounds than have to lose a bunch later." Again, "But you're skinny." At that point I stopped trying.
