Restrain app

Restrain is an app designed by our scientists that may help people lose weight and eat more healthily. The trial terminated in March 2023 and findings will be disseminated in due course.

The Restrain app is part of a wider research project to test whether different types of ‘brain training’ exercises can help people to lose weight.

The training tasks have already been tested in small groups of people, but now we want to find out whether they work on a large scale with people who are overweight or obese.

If the tasks do work, we want to discover what sort of training works best and who is likely to benefit the most. The project is the largest of its kind and we want you to be a part of it.

What it involves

The app involves completing different tasks each day.

You also need to weigh in once a week so we can track your progress.

You can participate as much or as little as you like – but the more you do, the better.
