IowaParamedic, that is awesome progress. Wow, 3-4 pounds a week!!!
I'm down to 211 now (from 225 a few months' back). I've been taking it slow and steady. My goal is 210. I'm 6'4", so that's about right for me.
I've noticed a lot of changes, too. I've had to buy a new wardrobe because my pants especially were dangling off me. I can easily ride in a more aerodynamic manner now for the entire commute because my knees no longer hit my gut.
