Title: Randomized Controlled Trial of a Water Beverage Intervention for Promoting Modest Weight Reduction in Free Living Adults
Brief Summary: 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.

The secondary objective is to identify mediators and moderators of the effect of water replacement including hydration status, glucose metabolism, anthropometrics, physical activity, dietary intake and resting metabolic rate.
