I guess I'm a little different for a lot of people here because I'm not trying to lose weight per se. I weigh in a 270, but it's a lot of muscle as I play football (O-Line) at college. But I do try to be healthy and I really enjoy working out. And because of that I've become very interested in how my body works and how different exercises and food and strategies affect it, so I actually know quite a bit about fitness and things that work.  

Other than that, I'm about to be a junior studying Chemical Engineering, and I love it.

Update: I'm done football, so am now trying to lose weight, I'm down to about 250, which I haven't been down to since junior year of high school.

I'm about to graduate with a BS in ChemE and have no idea what I'm doing next year! Yay for crappy economy :P
