I had a pudgy phase as a kid, and a skinny phase as an adult. At some point I made a deliberate effort to be more social and started lifting soon after.  I'm not built like a fitness model or anything, but being reasonably in shape has really alienated me from the die-hard (or "die early of beetus") gamer crowd I used to identify with.  Not sure how much is me (obviously I can't really stand fats anymore) and how much is their perception of me. Definitely seem to encounter fat, salty crabs more often, though.
