Shawn Johnson was really good at losing weight...for short periods of time. He'd have bursts of motivation, but the pounds always came back. Without fail, Shawn found himself giving in to temptation and watching the number on the scale creep back up. He'd say to himself that he'd change once he got to a certain weight — first it was 350 pounds, then 400, then 450 — but he continually passed these markers without making any modifications to his lifestyle. "I thought to myself that if I kept going in the direction I'm going, I'll end up on My 600-lb Life," he said.
