Web-based virtual reality to enhance behavioural skills training and weight loss in a commercial online weight management programme: The Experience Success randomized trial.

This study demonstrates the potential of Web-based VR skills training to enhance outcomes of commercial online weight management programmes that are widely accessible. Compared with traditional didactic methods for online skills training, VR simulation provides opportunities to learn behavioural skills via modelling and experiment with skills in real-world situations. More research is needed to identify specific behavioural mechanisms by which ES may improve outcomes.
