The standard public health guideline of 30 minutes of moderate-intensity physical activity daily is insufficient for preventing unhealthy weight gain or weight regain in many individuals.
To stop gaining weight, you likely need to do more than the standard '30 minutes a day' advice. Aim for 45-60 minutes of moderate activity (like brisk walking) every day. If you can't find that time, focus on reducing sitting and adding small bursts of movement (incidental activity) throughout your day.
However for preventing weight gain or regain this guideline is likely to be insufficient for many individuals in the current environment.
Why this rating
Based on a consensus of multiple prospective studies and meta-analyses reviewed by experts, though definitive data for specific PAL thresholds is noted as lacking.
