How did you do it in just a short time, yes the bigger you are it seems it does loose quicker, I was 230 and in 12 months lost 80 then the band slipped (still did not reach goal weight loss) put on 30 now since it its been 3 years and i'm at a stand still and feeling fat all over again, i,m having a hard time loosing now, and exercise is a key too and i'm being lazy
