This systematic review of 26 systematic reviews (covering 338 original studies) found that eHealth interventions for weight loss are more effective than control interventions or no care and comparable to face-to-face interventions, though effect sizes remain relatively small.
This systematic review of systematic reviews included 26 systematic reviews covering 338 original studies published between 2018 and 2023, evaluating eHealth interventions for weight loss and weight loss maintenance in adults with overweight or obesity. Studies were identified through searches of multiple databases and gray literature, with methodological quality assessed using the AMSTAR 2 tool. Two reviews were rated moderate quality, 13 low, and 11 critically low on AMSTAR 2. Interventions with human contact were found to work better than fully automated interventions. Key limitations include considerable heterogeneity among included trials, generally high or moderate risk of bias across included reviews, and limited studies focusing on long-term weight loss maintenance.
