This group used the PACE label plus calorie label to help participants to know about the number of minutes of walking or running required to burn off the calories in food and drinks.

This group used only calorie labels to show the number of calories in food and drinks.

There were 34 food and drinks choices available for consumption in the pop up café. The labels were displayed next to the food/drink item in the pop up café. The food items were kept in the same position for each participant kitchen to simulate the café environment. Then researchers changed the labels on the display according to the randomisation allocation of each participant. After randomsation participants were informed that they have £10 to spend in the pop-up café and that they could eat the food they selected in a private social eating room.

Participants had £10 to spend in the pop-up café and they could eat the food they selected in a private social eating room. The total money they spent were measured when they left the lab.

The researchers used a digital scale to weigh the original remaining food to the nearest 0.1 gram. The name of food items, the number of calories in each item selected, and the weight of leftover (using calibrated food weighing scales) was recorded for each participant. They were to ensure that all participants had finished eating and left the lab before weighing the remaining food.

24-hour physical activity questionnaire was sent to them via email one day after the experiment.
