Summary

The present study aims to investigate whether alcohol consumption is reduced when participants are shown calorie information of alcohol products, compared with when calorie information is absent. We also wish to see whether alcohol consumption levels are reduced when changing the serving sizes available to participants.

Conditions

  • Obesity and Overweight
  • Alcohol

Interventions

BEHAVIORAL

Calorie information manipulation

The intervention will be administered by changing the information presenting to participants at point-of-choice when ordering alcoholic drinks and bar snacks. When alcohol calorie information is present, participants will see the calorie content of alcohol products on menus and at other point-of-choice locations. When it is not present, this information will be absent.

BEHAVIORAL

Serving size manipulation

The intervention will be administered by changing the availability of alcoholic drinks. When serving sizes are reduced, participants will only be able to order 2/3 pint of 1/2 servings of beer, and 125 ml servings of wine. When serving sizes are not reduced, participants will be able to order 1 pint servings or 1/2 servings of beer, and 175 ml or 125 ml servings of wine.
