I get fat.
But seriously, since I went paleo, I've really started to notice the bloat that eating wheat gives you. When I cheat with wheat my belly grows something ridiculous and it takes a couple weeks for it to go away. I used to date know this vegetarian girl who was as skinny as could be, but still had this belly on her. I wish I still knew was in contact with her so I could suggest she give up wheat and see what happens.
