If you're anything like me, you've had a moment or two where you've looked around and noticed you're the biggest person in the room, or state (ok, probably not. But it feels like it sometimes), and thought, "Why me? What makes me so different that I'm fat and none of these people are?" I usually come to the conclusion that it's something out of my control.
There are things that are out of my control. My genetics, my upbringing, the fact that I've been evolutionarily hardwired to crave salt, fat, and sugar, etc. The big bulk of the blame, however, falls on my shoulders. I'm the one who feeds myself. Everything else is just excuses. We all make excuses. They're a natural defense mechanism to prevent cognitive dissonance.
Blame aside, it's still tough to deal with the fact that you're heavier than anyone else around you. I've been the fattest guy in class, the fattest guy at work, the fattest guy in the restaurant, etc. If you feel that way, let it light a fire under you. You don't have to be the biggest person in the room. You can change. I can change. I am changing.
