Adherence
An interactive smartphone app-based lifestyle intervention combining wearable activity tracking, smart scales, food photography logs, and physician coaching produces statistically significant and clinically meaningful weight loss (-7.16 kg) and improved metabolic health (waist circumference, HbA1c) compared to conventional outpatient visits alone.
Use a smartphone app that integrates a smart scale and activity tracker. Log your meals with photos rather than manual entries. Engage with a coach and peers through the app. Attend regular check-ins. This combination of automated tracking and human support can lead to significant weight loss and improved metabolic health.
At 6 months, the intervention group experienced a statistically significant weight change of −7.16 ± 1.78 kg... which differed from the weight change in controls by −4.16 ± 2.01 kg... Waist circumference and hemoglobin A1c significantly improved... This app‐based electronically delivered lifestyle intervention produced statistically significant, clinically meaningful weight loss and improved metabolic health.
