Digital health tools are now everywhere in obesity care, and their role is anything but simple. Apps, wearable trackers, and online consultations can make weight monitoring and lifestyle support far more accessible. Yet, in some cases, they seem to pull people into longer stretches of sitting, which can undercut the very goals they aim to support. This review looks at recent studies to get a clearer picture of that trade-off — how these technologies can both encourage healthier habits and, unintentionally, promote inactivity. We discuss possible reasons for this mixed impact and suggest practical ways to keep the benefits while limiting the downsides. The aim is to give healthcare providers and tech developers a grounded, realistic view of how to use digital tools more effectively in obesity prevention and treatment.
