Adherence
Labelling a single food or drink option does not significantly change the amount of energy consumed during a snack or meal.
Putting nutritional labels on single food items (like a chocolate bar or a soda) does not significantly change how much energy you consume when eating that item.
LimitedRefutesLOW confidence
A meta-analysis of these studies did not demonstrate a statistically significant difference in energy (kcal) consumed (SMD 0.05, 95% CI −0.17 to 0.27, N = 732).
Why this rating
The Cochrane review rates the evidence as 'low' quality.
