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 .
Sugar- and artificially sweetened beverages and intrahepatic fat: A randomized controlled trial.
OBJECTIVE To test the hypothesis that substituting artificially sweetened beverages ( ASB ) for sugar-sweetened beverages ( SSB ) decreases intrahepatocellular lipid concentrations ( IHCL ) in overweight subjects with high SSB consumption . METHODS About 31 healthy subjects with BMI greater than 25 kg/m(2 ) and a daily consumption of at least 660 ml SSB were r and omized to a 12-week intervention in which they replaced SSBs with ASBs . Their IHCL ( magnetic resonance spectroscopy ) , visceral adipose tissue volume ( VAT ; magnetic resonance imaging ) , food intake ( 2-day food records ) , and fasting blood concentrations of metabolic markers were measured after a 4-week run-in period and after a 12-week period with ASB or control ( CTRL ) . RESULTS About 27 subjects completed the study .  IHCL was reduced to 74 % of the initial values with ASB ( N = 14 ; P < 0.05 ) but did not change with CTRL . The decrease in IHCL attained with ASB was more important in subjects with IHCL greater than 60 mmol/l than in subjects with low IHCL . ALT decreased significantly with SSB only in subjects with IHCL greater than 60 mmol/l . There was otherwise no significant effect of ASB on body weight , VAT , or metabolic markers . CONCLUSIONS In subjects with overweight or obesity and a high SSB intake , replacing SSB with ASB decreased intrahepatic fat over a 12-week period
