Adherence
Sedentary behavior interventions lasting 2 weeks to 6 months in non-clinical adults produce small but statistically significant improvements in body weight, waist circumference, body fat percentage, systolic blood pressure, fasting insulin, and HDL cholesterol.
If you sit for long periods, try to break up your sitting time with standing or light walking. Even small reductions in total sitting time (e.g., 30-60 minutes less per day) can lead to small but real improvements in weight, waist size, blood pressure, and insulin sensitivity over a few months. You don't need intense exercise to get these specific metabolic benefits; simply replacing sitting with light activity is effective.
Pooled effects revealed small, significant (p<0.05) beneficial effects on weight (≈ −0.6 kg), waist circumference (≈ −0.7 cm), percentage body fat (≈ −0.3 %), systolic blood pressure (≈ −1.1 mm Hg), insulin (≈ −1.4 pM) and high- density lipoprotein cholesterol (≈ 0.04 mM).
Why this rating
Systematic review with meta-analysis of 33 controlled trials, though heterogeneity was wide and risk of bias was mixed.
