Hi Fashion,
If she has only 50 pounds to lose, it's likely that she won't qualify for band surgery. You have to meet a set of criteria which include a pretty high BMI and co-morbidities. The loss with the band is different than with RNY. It's slower - trust me on this! We don't dump and can eat all kinds of food. The amount of weight you lose depends on how well you work the tool.
Good luck to your friend!

p.s. JIFFYPOO! I didn't see your post 'til today. You're right - spring training does bring out the wildlife. Woo hoo! I'm great - still working on getting weight off, but happy and not as fat. :-)
