Adherence
Remote behavioral weight-loss interventions (telephone, web, email) achieve clinically significant weight loss (mean -4.6 kg) comparable to in-person support (-5.1 kg) over 24 months in primary care settings.
You can lose significant weight using remote tools (phone, web, email) without needing to attend in-person group sessions. The study showed that a remote program resulted in nearly the same weight loss (-4.6 kg) as an in-person program (-5.1 kg) over two years. To succeed, you must log in weekly, use the provided tracking tools, and respond to automated reminders.
At 24 months, the mean change in weight from baseline was ... -4.6 kg in the group receiving remote support only ... and -5.1 kg in the group receiving in-person support ... The change in weight from baseline did not differ significantly between the two intervention groups.
Why this rating
Randomized, controlled trial with a large sample size (N=415) and long duration (24 months).
