Brief Summary

This study aims to compare the effectiveness and adherence of three web-based weight management interventions, all based on the HealthyWeightCoaching (HWC) within a HealthyWeightHub.fi (HWH) platform. HWC is a 12-month web-based intervention including information and exercises to promote weight loss. Each patient is allocated a personal coach to encourage progress on the platform. In the current setting, the investigators study how minimal added support will affect the effectiveness and adherence of the web-based program. The patients are randomized into three groups all of which include the HWC platform. In addition, group 1 will be offered three individual face-to-face sessions via video and group 2 three group face-to-face sessions via video. Group 3 acts as the control group offering the basic HWC protocol. The patients (target n=120) are enrolled from the occupational health of the city of Helsinki.
