Adherence
Exposure to shorter, wider bottles or glasses (vs. taller, narrower) increases the quantity of non-alcoholic beverages selected and consumed.
Using shorter, wider glasses or bottles may lead you to pour and drink more than using taller, narrower ones. If you want to drink less, consider using taller, narrower containers.
WeakSupportsVERY_LOW confidence
One included study (50 participants) estimated a large effect on consumption of exposure to differently shaped tableware (SMD 1.17, 95% CI 0.57 to 1.78), rated as very low quality evidence that exposure to shorter, wider bottles (versus taller, narrower bottles) increased quantities of water consumed by young adult participants.
Why this rating
Very low quality evidence, based on one study with 50 participants.
