Not really a last resort anymore, although Yoni loathes the lap band because of a study that compared the success rate between Gastric Bypass, Gastric Sleeve and Lap band. The lap band failed horribly in comparison to Bypass which was by far the best method with truly promising results for those in trouble. Sleeve was a second to it, with it having solid success but he recommends to his patients only the Gastric Bypass because of the side benefits from it which most definitely the lap band does not provide.
I cannot emphasize this enough, the brain stomach connection is very powerful, the hormone grehlin which has been found to have profound impact on if people because of its key role in telling the brain its hungry.
We are at the start of all this research with this brain stomach connection and Gastric Bypass surgery allows a reset of sorts, which will give the patient a vastly better chance at keeping the weight off.
