Non-nutritive sweetened beverages versus water after a 52-week weight management programme: a randomised controlled trial

J. A. Harrold, S. Hill, et al.

In a groundbreaking study conducted by Joanne A. Harrold and colleagues, this randomized controlled trial reveals that non-nutritive sweetened beverages may offer a slight advantage in weight loss over water. Over 52 weeks, both beverage groups experienced weight loss, but the NNS group lost 7.5 kg compared to 6.1 kg in the water group, highlighting the potential of NNS drinks in behavioral weight management programs.

Abstract

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.
