When comparing NNS vs sucrose , significant weight/ BMI differences appeared favouring NNS .
Consumption of NNS led to significantly negative weight/ BMI differences in unrestricted energy diets , but not in weight-reduction diets .
Participants with overweight/obesity and adults showed significant favourable weight/ BMI differences with NNS .
Data suggest that replacing sugar with NNS leads to weight reduction , particularly in participants with overweight/obesity under an unrestricted diet , information that could be utilized for evidence -based public policy decisions
There is an ongoing debate about the possible influences of nonnutritive sweeteners ( NNS ) on body weight .
We conducted a systematic review and meta- analysis of r and omized controlled trials ( RCTs ) with NNS to assess their impact on body weight .
The effects of water and non‐nutritive sweetened beverages on weight loss and weight maintenance: A randomized clinical trial
Objective To evaluate the effects of water versus beverages sweetened with non‐nutritive sweeteners ( NNS ) on body weight in subjects enrolled in a year‐long behavioral weight loss treatment program . Methods The study used a r and omized equivalence design with NNS or water beverages as the main factor in a trial among 303 weight‐stable people with overweight and obesity . All participants participated in a weight loss program plus assignment to consume 24 ounces ( 710 ml ) of water or NNS beverages daily for 1 year . Results NNS and water treatments were non‐equivalent , with NNS treatment  showing greater weight loss at the end of 1 year . At 1 year subjects receiving water had maintained a 2.45 ± 5.59 kg weight loss while those receiving NNS beverages maintained a loss of 6.21 ± 7.65 kg ( P < 0.001 for difference ) . Conclusions Water and NNS beverages were not equivalent for weight loss and maintenance during a 1‐year behavioral treatment program . NNS beverages were superior for weight loss and weight maintenance in a population consisting of regular users  of NNS beverages who either maintained or discontinued consumption of these beverages and consumed water during a structured weight loss program . These results suggest that NNS beverages can be an effective tool for weight loss and maintenance within the context of a weight management program
