Energy balance

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.
