Study Type

Weight Loss/Obesity

Study Purpose

The purpose of this research study is to test a hydrogel capsule for its effects on weight loss.

About the Study

The hydrogel capsule is an orally taken pill that helps the body to have a continuing sense of fullness during and after meals. The capsule does not release any chemicals, is not absorbed into the body, and comes out as waste.

Participants will be randomized into one of two groups: one will receive the hydrogel capsule and one will receive the placebo capsule. Participants will be asked to take one capsule twice a day before their main meals and complete a daily food/activity diary. Throughout the duration of the study, volunteers will also receive 14 brief (15 minutes) lifestyle counseling visits.
