First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new digital weight management program for adults with obesity who are referred to NHS Tier 3 services. The program uses a smartphone app to help people manage their weight. Researchers want to see if it improves health, saves money, and works well for patients and doctors. About 580 participants will be followed for 12 months.

- What this could lead to
- If successful, this could provide an effective, scalable digital tool for managing obesity within the NHS, potentially improving health outcomes and reducing costs.
