Adherence

Digital dietary interventions specifically lead to greater reductions in body weight, BMI, and fasting blood glucose compared to nondigital dietary interventions.

If you are focusing on diet, using a digital tool (app, wearable) may yield better results for weight loss and blood sugar control than traditional methods like pamphlets or face-to-face counseling alone.

ModerateQualifiesMEDIUM confidence
Subgroup analyses showed that digital dietary interventions significantly reduced body weight (MD = −0.66, 95% CI [−1.26, −0.06]), body mass index—BMI (MD = −0.25, 95% CI [−0.43, −0.07]), and fasting blood glucose (MD = −0.31, 95% CI [−0.57, −0.05]) compared to nondigital interventions.
