Improving diet quality of people living with obesity

The chat2 study is testing a new weight management program led by dietitians to support people in building healthy habits.

What’s the study about?

The aim of this 1-year study is to see if providing people with access to a dietitian through telehealth by video can help people improve the quality of their diet and generally feel better about themselves.

Half the people who take part will be asked to continue with current best care for obesity with their doctor and half will be given the chat2 program.

People will not be able to choose which group they are in as this is decided randomly, like tossing a coin. The study will use an app on people’s mobile telephone to help record their diet through taking pictures.
