   GPS-tracked activity plans trim weight and body fat

   GPS-enabled physical activity programmes produced small but significant reductions in body weight and body fat percentage across nine randomised trials in adults, and adding dietary components did not consistently beat activity-only interventions. Short-term programmes of three months or less showed the greater weight effects.

   ⚠What it shows: Meta-analysis of nine RCTs (1363 adults, mostly female); effects were small, the body-fat result was highly heterogeneous across studies, and robustness was only supported for short-term outcomes.Meta-analysis · Nutrients

   Texts nudged blood pressure down in pooled trials

   Pooled across 22 randomised trials, text-message interventions improved medication adherence and reduced systolic blood pressure by 6.12 mmHg and diastolic by 2.66 mmHg, but produced no significant improvement in BMI, LDL, HDL, total cholesterol or HbA1c.

   ⚠What it shows: Meta-analysis of 22 randomised trials, but heterogeneity between studies was extreme for the blood-pressure outcomes (I² of 96% for systolic and 85% for diastolic), populations varied widely, and long-term effects were not established.Meta-analysis · BMC Public Health
