Why is Zanocap touted as the Healthy Gastric Bypass Alternative ? Gastric bypass works by actually making your stomach smaller with the aid of expensive and possibly dangerous surgery. The scientifically proven Nano-Fiber technology utilized in our manufacturing process (in a US based bonded and insured FDA inspected laboratory) creates a gel-like substance in your stomach that enables your stomach to feel fuller even though you have consumed less calories. It is the exact same effect as a bypass - you eat less because you already feel full. Why go under the knife when there is an all-natural and healthy product that has the same effect without the expense and danger?
