I lost 110 pounds last year w/o surgery ---just diet and exercise . I started on New years day. I have 30 more to go. That's why I'm up at 4:30 a.m. and headed the gym. Keeping it off is just as hard as losing it. I have rheumatoid arthritis and the diet change has been a god send. Good luck to all who will try ( and succeed!!) this year. You CAN do it.
