Trial of a Water Beverage Intervention for Promoting Modest Weight Reduction in Free Living Adults

Completed · Not applicable

Conditions studied: Obesity

In brief

The primary objectives of this clinical trial are to determine if replacing sugar sweetened beverages with water consumption promote weight loss over 6 months in overweight adults and if replacing sugar sweetened beverages with water consumption promote greater weight loss over 6 months relative to replacement with other non-caloric sweetened beverages or control.
