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 .
An evaluation of the effect of aspartame on weight loss
This study explores whether the addition of aspartame-sweetened foods and beverages to a low fat , hypocaloric diet enhances compliance and result ing weight loss .  Fifty-nine obese ( 130 - 225 % of ideal body weight ) , free living men and women were r and omly assigned to either a Balanced Deficit Diet ( BDD ) or a BDD supplemented with aspartame . Over a 12-week weight loss period , volunteers attended weekly support group meetings including behavior modification training and exercise instruction . Males achieved a clinical ly significant weight loss ( greater than 23 lb ) in both study groups , while females lost an average of 12.8 lb in the control group vs. 16.5 lb in the experimental group . In both treatment groups , sleep , general energy level , level of physical activity , and feeling of well-being showed clinical ly meaningful improvement . This study suggests possible advantages to supplementing a BDD with aspartame-sweetened foods as part of a multidisciplinary weight loss program . The small sample size prohibits definitive conclusions but does provide the protocol for a larger , outpatient clinical trial
