For GPs

About the Study

The “Connecting Health and Technology” (chat2) randomised controlled trial is offering people living with obesity a free, one year, world class weight management study aimed at supporting behaviour change, building healthy habits, and improving diet. The study design provides benefits to both the control and intervention groups, so both groups will learn how to improve their dietary intake prior to considering other interventions such as medication or surgery.

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