Optimising a digitally delivered behavioural weight loss programme: study protocol for a factorial cluster randomised controlled trial.

ABSTRACT:

Background

Digitally delivered weight loss programmes can provide a convenient, potentially cheaper, and scalable treatment option for people who may need to lose weight. However, outcomes are often inferior to in-person interventions in the long-term. This trial will use principles from the Multiphase Optimisation Strategy (MOST) framework to test whether it can enhance the effectiveness of a commercial digital behavioural weight loss programme. This trial aims to identify an optimised combination of four intervention components to enhance weight loss over a 24-week period. We will also explore which components contribute to improvements in participant retention and engagement with the programme.

Methods

Approximately 1400 adults with a BMI > 21 kg/m² will be enr
