I went from 270 lbs to 203 lbs in 9 month eating a very strict diet, being hungry 24/7 a doing a lot of bike and eliptical trainer. I started eating normaly after a year and got back at 215-220 even if I ride 55 kms/day 4 days a week plus my week end ride which is around 150 kms each week end. I'd prefer if I could stay at 200 lbs but I can't stand being hungry so I'm now happy at 215 (still better than 270!)
