I will add my .02 as far as the surgery goes...I don't know much about jiuce so I cannot tell you any info on that.
However what I can say is that before even being accepted and receiving a date for the surgery you will have many weigh ins at the health clinic along with meetings with nutritionist about eating properly and you will also be given a strict work out routine to follow. Many people who are due to get the lap band or complete bypass have made great progress on this alone as long as they are not in the 500 lb range (which in this area would not be eligible for the surgery any ways due to possible death on the table)..With that being said, I think that as long as there is a nice diet and a complete work out routine to follow one who is not too severely obese can lose a great deal of weight and look great..My neighbor is currently in the upper 200 lb range and is set to have a date scheduled next week for her bypass, in order to get the ok for the procedure she had to lose atleast 50 lbs, after following a healthy diet and strict work out she has proudly lost far more than expected.....Again I don't know much about anabolic however I would get advice from a nutritionist on what is best for you personally.
