I'm am also in my 20's and am looking to get banded in September. When I spoke with my doctor they said the their younger patients have some of the best results! One of my good friends who was banded a few years ago at age 20 lost 85 lbs without much, if any, working out! Also, like those above, I have been told that your skin is much more likely to go right back. I'd love to talk to you further, i've been looking for someone to share in my journey with who understand what its like.
