A large portion of the United States’ population is overweight. The use of garcinia has been rapidly growing in the United States due to the desire of people to lose weight. As part of a lifestyle that includes good nutrition and exercise, garcinia may favorably modify metabolism and appetite. These benefits could help people lose weight and lead healthier, more active lives.

Reported Uses

Research suggests garcinia may modulate blood fat levels. (1) This effect, scientists say, can lead to increased energy and metabolism. (2) These findings are supported by another study that found that subjects using garcinia in addition to niacin-bound chromium and a reduced-fat diet lost three times more weight than those on a diet alone. (3)

The appetite-suppressant mechanism of garcinia is thought to be due in part to its role in stimulating the production of glycogen in the liver and small intestine. (4) When glycogen is produced, the brain receives a signal that the stomach is full and satisfied.

There is some concern regarding the effectiveness of garcinia for weight loss. A study of 89 mildly overweight women tested the effectiveness of garcinia in weight loss. (5) Forty-two participants took garcinia and forty-seven participants took placebos. The garcinia group did not show better compliance to the diet, significant appetite changes, an increase in energy, or a weight change.
