This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information. In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.


What is the study about?

We are looking at different treatments for people who are living with obesity to see what can improve health and quality of life. For people who haven’t been able to lose weight any other way, an option is weight loss surgery but we have some evidence that a combination of other treatments may be just as helpful. The treatment we want to test is a two year programme which includes weight loss coaching and dieting.

Who can take part?

We are running this study in partnership with hospitals around the UK and in order to take part you must have been invited by one of these hospitals directly. You won't be able to access the study unless you have been invited. If you are under the care of one of these hospitals and you are eligible to take part, you will receive contact from them.
