Summary

This trial will compare a new weight-loss program to the current gold standard to see which is more effective and cost-efficient.

Who is the study for?
This trial is for adults with obesity, having a BMI between 30-45, who own and can use a smartphone. Participants should be willing to install an app and do video calls with the study team. It's not for those on weight loss programs, insulin-treated diabetes, recent psychiatric hospitalizations, moderate exercise-induced cardiovascular symptoms, pregnant or lactating women, Crohn's Disease sufferers, bulimia or binge eating disorders patients.
What is being tested?
The study compares two methods to treat obesity: one group uses a specially designed smartphone app (APP) while the other follows the Diabetes Prevention Program (DPP). The goal is to see which method helps people lose more weight effectively and affordably.
What are the potential side effects?
Since this trial involves lifestyle interventions rather than medications, side effects are minimal but may include potential stress or frustration from dietary changes or new exercise routines.
