Low Calorie Sweeteners Help Reduce Body Weight

From "Low energy sweeteners help reduce energy intake and body weight" in ScienceBlog:

Use of low energy sweeteners (LES) in place of sugar, in children and adults, leads to reduced calorie intake and body weight – and possibly also when comparing LES beverages to water – according to a review led by researchers at the University of Bristol published in the International Journal of Obesity today.

For the first time, all available science was integrated into a single review to evaluate the real impact of LES, such as saccharin, aspartame, sucralose and stevia, on energy intake (EI) and body weight (BW) over the short- and long-term. A considerable weight of evidence confirmed that consuming LES instead of sugar helps reduce relative energy intake and body weight.***The authors conducted systematic reviews of relevant studies in animals and humans consuming LES in a non-restricted diet. In total, 12 human prospective cohort studies, 228 comparisons in human intervention studies (short and long-term) and 90 animal studies were examined.
