At 50 yrs.old my doctor told me to have gastric bi-pass or I won't see 51 yrs.old. Three weeks later I was in surgery. After a year I met my goal weight. I had lost 110lbs. That was 9 yrs. ago. I am still thin. I am not sorry. Just remember to follow what your nutritionist tells you. Think healthy and happy. GOOD LUCK!! YOU CAN DO IT!
