Non-nutritive sweetened beverages versus water after a 52-week weight management programme: a randomised controlled trial
Authors' conclusion
During a 52-week behavioural weight management programme, water and NNS beverages were non-equivalent, with weight loss maintained to a statistically greater extent with NNS beverages compared with water. However, this difference was not clinically significant.
