Reordering food options on delivery apps could help to reduce obesity

Obesity is one of the biggest health challenges in the UK. Most people would like to keep to a healthy weight but this has become extremely difficult in a world that constantly pushes us towards eating too much.

This paper explores whether reordering food options on delivery apps could help reduce obesity. Together with the Behavioural Insights Team (BIT) and the University of Oxford, we carried out a UK-wide experiment involving more than 7,000 participants. They were asked to order food using one of four simulated food delivery apps. We discovered that simply repositioning options in relation to their calorie content significantly reduced the amount of calories ordered.
