White kidney bean extract is more commonly known as phaselous vulgaris—a member of the family that includes beans, legumes, etc. It is advertised as a weight loss product because of its ability to block the production of carbohydrates associated with the pancreas. More appropriately white kidney bean extract slows the production of the enzymes—produced by the pancreas—that causes the breakdown of sugars associated with foods high in glucose (sugar).
A study performed over a 30-day trial period, proved that the subjects who were given the extract had a lower BMI than those who took the placebo. The dose was given before meals high in carbs, and the subjects had a greater weight loss, as well.
According to advertisement, white kidney bean extract:
• Slows alpha-amylase production
• Leaves less sugar behind to prevent abdominal fat, and can reduce obesity
• Regulates blood sugar
• Can prevent diseases such as diabetes
• Increases metabolism, and or energy
• Alleviates arthritic symptoms
• Aids in the prevention of colon cancer
• Reduces fat to allow for a leaner body mass
It is recommended that those considering the use of the extract contact a physician before taking the weight loss capsules. While it does block fat production, it can also decrease nutritional values in the foods consumed. Therefore, anyone taking white kidney bean extract should maintain a healthy diet, and get a reasonable amount of exercise. It is not recommended for women who suspect that might be pregnant or for women who are nursing babies, and should never be given to children.
Overall, according to the studies that have been done involving the extract, it does prove to be a good weight loss supplement.
