Adherence
Nutritional labelling on menus or food options in laboratory settings does not conclusively reduce energy consumed during a meal.
In controlled laboratory settings, seeing nutritional labels on food options does not consistently lead to eating less. The effect is uncertain and may not translate to real-world consumption.
LimitedQualifiesLOW confidence
A meta-analysis of these studies did not conclusively demonstrate a reduction in energy consumed during a meal (MD −50 kcal, 95% CI −104.41, 3.88, N = 1705).
Why this rating
The Cochrane review rates the evidence as 'low' quality.
