That is what the surgeon suggest based on my weight....283 and my weight loss goal is 150. I would be fine weighing 170-180, but he asked me what I would ideally like to weight. I see a lot have the sleeve. I have a friends who had G Bypass 9 years ago and has gained some back, Nothing like she was before though. She knows a lot of people who has had WLS due to going to a lot of support groups over the years and she says she wishes she had chosen the DS due to the fact that it seems to be very successful in keeping the weight down. Why did you chose the Loop? I don't know much about that one. It's not listed as a choice on the website or all the paperwork in a big binder they gave me.
