A web-based programme (POWeR) with nurse support helped about 30% of people lose at least 5% of their body weight, maintained for at least 12 months. By comparison, twenty percent of people achieved this with an online information sheet only. | National Institute for Health Research (NIHR)
POWer+ helped more people achieve short-term weight loss but the average weight loss of about 3-4 kg after 12 months was statistically similar for those given information only. The healthy eating online materials tested had previously been shown to help people to control their weight, without expert advice.
This NIHR research showed that the web programme, with phone or email support from nurses, had a modest benefit and was probably cost-effective. It represents one option that could be offered to patients.
