This 90-day randomized controlled trial in older Chinese adults with overweight/obesity found that a combined remote dietary and physical activity intervention significantly reduced energy intake, body weight, BMI, and improved several cardiometabolic markers compared to control, while a physical activity-only intervention did not significantly improve physical activity.

This 90-day randomized controlled trial assessed smartphone-based remote interventions in 750 older adults with overweight or obesity. Participants were assigned to a remote dietary and physical activity intervention group, a remote physical activity intervention group, or a control group. This group also demonstrated significant improvements in systolic blood pressure, triglycerides, and fasting blood glucose. The study suggests that a remote management model integrating dietary guidance is effective for weight control and offers potential cardiometabolic benefits in this population, though the sustainability of effects and the interaction between dietary and activity components require further investigation.
