Adherence
GPS-enabled physical activity interventions produce significant short-term reductions in body weight and body fat percentage in adults, with effects comparable to or exceeding those of combined physical activity and dietary interventions.
Use a GPS-enabled fitness tracker or app to monitor your daily movement. Focus on consistency rather than perfection. The data shows that short-term, consistent activity tracking (under 3 months) yields the best weight loss results. You do not necessarily need to add a strict diet plan if you are using a smart tracking system, as the behavioral feedback from the device alone can drive significant fat loss. Prioritize ease of use to maintain adherence.
GPS-enabled PA interventions significantly reduced body weight (Hedges’ g = −0.241... p = 0.380) and body fat percentage (BFP) (Hedges’ g = −0.412... p = 0.002)... interventions involving PA alone produced a moderate effect on weight reduction (Hedges’ g = −0.328)... whereas those combining PA with dietary strategies showed a slightly smaller yet significant effect (Hedges’ g = −0.208)... Notably, the addition of dietary components did not consistently provide greater benefits compared to PA interventions alone.
Why this rating
Based on a systematic review and meta-analysis of 9 RCTs with 1363 participants, though heterogeneity was noted for BFP.
