Energy balance

Substituting low-energy sweeteners (LES) for sugar in beverages and foods reduces total energy intake and body weight in both adults and children compared to sugar-sweetened alternatives.

If you want to reduce your calorie intake and body weight, replacing sugar-sweetened beverages and foods with low-energy sweetened alternatives is an effective strategy. This substitution leads to a measurable reduction in energy intake and body weight compared to consuming sugar, without increasing appetite or causing compensatory overeating.

StrongSupportsHIGH confidence
The preponderance of evidence from all human randomized controlled trials indicates that LES do not increase EI or BW, whether compared with caloric or non-caloric (for example, water) control conditions. Overall, the balance of evidence indicates that use of LES in place of sugar, in children and adults, leads to reduced EI and BW, and possibly also when compared with water.
