  • Background: Sugar sweetened beverages (SSBs) have been associated with rising obesity rates. Replacing caloric beverages with noncaloric beverages may be a successful strategy for weight loss however little research has examined predictors of success among those seeking to reduce caloric beverages.Design: Overweight and obese adults (n=318) were randomized to either a control group or 1 of 2 intervention groups. The intervention groups substituted caloric beverages with water or diet soda. Beverage intake was measured at baseline and weight was measured at baseline and 6 months. This secondary data analyses examined predictors of beverage consumption at baseline and predictors of weight loss at 6 months among participants in the intervention groups.Results: Race and education were associated with greater baseline daily average calories from beverages such that White participants and those with a college degree consumed fewer calories than other minority participants and those without a college degree. Additionally, both race and gender were associated with percent weight loss. Men lost twice as much weight as women, and white participants lost about 1/3 more than more African Americans. High soda consumers (consuming more than 40% of their daily beverage calories from soda) were found to also consume more calories from all beverages however, they did not show more weight loss than low soda consumers and their weight loss did not differ by intervention group (diet vs. water).Conclusions: Replacing caloric beverages with non-caloric beverages resulted in significant weight loss, however, the strategy was most successful among males. Men lost almost 5% of their body weight using this strategy. Future weight loss research should include more male participants to allow further study of this approach.
