Use of low energy sweeteners (LES) in place of sugar among children and adults leads to reduced calorie intake and body weight, according to a review led by researchers at the University of Bristol published in the International Journal of Obesity.
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 helped reduce relative energy intake and body weight, according to researchers.
Lead author Professor Peter Rogers from the University of Bristol said, “We believe that we should shift the question from whether LES are ‘good’ or ‘bad,’ and rather focus on how they should be best used in practice to help in the achievement of specific public health goals, such as the reduction of intakes of free sugars and energy.”
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.
Managing energy balance (i.e., energy intake vs. energy expenditure) well results in a steady body weight. On the contrary, eating an excessive amount of food causes an increase in body weight, as this extra energy is stored in the body as adipose tissue (fat).
The comparison between LES beverages and water was important because it showed LES do not increase appetite. If anything, the evidence suggested LES beverages reduced weight more than water, researchers said. One reason for this may be that switching from sugar-sweetened drinks to those with LES may be an easier and more acceptable dietary change to make than switching to water, they concluded.
