I have to disagree, the amount of weight lost has nothing to do with how much you weigh. Everybody is different. For instance, my mother was 270 before her gastric bypass, at 5'7" her goal weight is 170. So that's 100 pounds. The fact that you are only 5' your suggested goal weight would be 115 to 130. So technically you need to lose the same amount as her. I don't see how that would make you any different than her. She had gastric bypass in March and she has already lost 80". On the other hand, I have friends who have had gastric sleeve that have lost as much weight and at the same rate. Whatever surgery you choose, it's gonna be hard, but there's no way of knowing how much or how fast you will lose weight. That all depends on how much effort you put in, but you could be just as successful as anyone else. Most people do lose the majority of their weight the first year, but honestly you would have less saggy skin if you did only lose 10 pounds a month. So it's a win either way, lol!
