This randomized controlled trial compared the effects of non-nutritive sweetened (NNS) beverages and water on body weight during a 52-week behavioral weight management program. 493 adults with BMI 27–35 kg/m² were randomized 1:1 to either group. At week 52, the NNS beverage group showed greater weight loss (7.5 kg) compared to the water group (6.1 kg), a statistically significant difference (1.4 kg; P<0.05), though not clinically significant (defined as >1.5kg). The findings suggest that while both beverages support weight loss, NNS beverages may offer a slight advantage in weight maintenance within the context of a behavioral program.
