No impact of calorie or unit information on ad libitum alcohol consumption

In this experimental human laboratory study, participants were randomized to one of
four conditions, balanced by gender, using a 2 (unit information: present vs. absent) × 2 (calorie information: present vs. absent) between-subjects design. The percentage of beer consumed during the taste test was the primary outcome measure. We find no evidence to support an effect of unit or calorie information on drinking behaviour.
