I'm just watching what I eat, and eating smaller portions.
Last June I spent a week in the hospital with a pretty bad case of pneumonia. When I got out, I was at 309 lbs. Right now I'm at around 250(it fluctuates +/- 3 lbs.), and lost all of it just by watching how much I eat. I haven't started exercising until now. I waited until we figured out what else was wrong with me, but now that I know(MGUS) I can start. I've got a treadmill in the basement, and my wife wants me to start walking with her in the mornings, so maybe that's all I need to do to get rid of the last 50 lbs.
