Data concerning effects of aspartame on main metabolic variables associated to diabetes and obesity do not support a beneficial related to its consumption
ABSTRACT Data about harms or benefits associated with the consumption of aspartame , a nonnutritive sweetener worldwide consumed , are still controversial .
This systematic review and meta- analysis of r and omized controlled clinical trials aim ed to assess the effect of aspartame consumption on  metabolic parameters related to diabetes and obesity .
The effect of aspartame as part of a multidisciplinary weight-control program on short- and long-term control of body weight.
This study investigated whether the addition of the high-intensity sweetener aspartame to a multidisciplinary weight-control program would improve weight loss and long-term control of body weight .  One hundred sixty-three obese women were r and omly assigned to consume or to abstain from aspartame-sweetened foods and beverages during 16 wk of a 19-wk weight-reduction program ( active weight loss ) , a 1-y maintenance program , and a 2-y follow-up period . Women in both treatment groups lost approximately 10 % of initial body weight ( 10 kg ) during active weight loss . Among women assigned to the aspartame-treatment group , aspartame intake was positively correlated with percentage weight loss during active weight loss ( r = 0.32 , P < 0.01 ) . During maintenance and follow-up , participants in the aspartame group experienced a 2.6 % ( 2.6 kg ) and 4.6 % ( 4.6 kg ) regain of initial body weight after 71 and 175 wk , respectively , whereas those in the no-aspartame group gained an average of 5.4 % ( 5.4 kg ) and 9.4 % ( 9.4 kg ) , respectively . The aspartame group lost significantly more weight overall ( P = 0.028 ) and regained significantly less weight during maintenance and follow-up ( P = 0.046 ) than did the no-aspartame group . Percentage weight losses at 71 and 175 wk were also positively correlated with exercise ( r = 0.32 , P < 0.001 ; and r = 0.34 , P < 0.01 , respectively ) and self-reported eating control ( r = 0.37 , P < 0.001 ; and r = 0.33 , P < 0.01 , respectively ) . These data suggest that participation in a multidisciplinary weight-control program that includes aspartame may facilitate the long-term maintenance of reduced body weight
