Adherence
Short-term GPS-enabled physical activity interventions (≤3 months) produce greater weight loss effects than longer-term interventions (≥6 months).
If you start a fitness tracking program, expect the biggest results in the first 3 months. To maintain weight loss after that, you must actively work to keep the habit, as the 'newness' of the app will wear off. Consider switching to a less intrusive tracking method or adding social accountability to sustain engagement beyond the initial quarter.
Short-term interventions (≤3 months) demonstrated greater effects on weight reduction... the most pronounced weight loss effects occurred within the first three months of GPS-enabled PA interventions (Hedges’ g = −0.239, 95% CI = −0.386 to −0.092)... while outcomes at six months were attenuated and not statistically significant (Hedges’ g = −0.221, p = 0.080).
Why this rating
Based on subgroup analysis of the same meta-analysis; robustness supported by sensitivity analyses.
