First of all, it must be pointed out that digestion of starches does not simply take place in the bowel, but that it begins in the mouth and is not completed until it absorbed by the body from the small intestine. The function of the bowel in digestion is to reabsorb water from the intestine into the body, and to prepare feces for excretion. When carbohydrates are ingested, saliva-amylase is immediately released into the mouth and esophagus and begins the break down of the food into starches and sugars. After swallowed, the carbohydrates are digested further by acid in the stomach. The final stage of digestion occurs in the small intestine, where an alpha-amylase enzyme further reduces the complex sugars, which are then absorbed as calories from the intestinal wall into the bloodstream.
Doctors agree that the logic in the idea is reasonable.
It is suggested that the product could inhibit the action of alpha- amylase by binding with the enzyme to stop the combining of starch with the enzyme. Hence, the carbohydrates should pass through the digestive tract without being broken down into simple sugars. The body cannot absorb large complex sugars, so the calories should simply pass through the tract and be excreted as feces. Most researchers who have tested this claim, however, have found that the theory does not carry well in reality. Critical Reviews Dr. Marshall reports that he has proven his product's effectiveness in both animal and human clinical studies.
