Energy expenditure = Burned calories

According to the US Surgeon General, significant health benefits can be gained by performing at least 30 minutes of moderate intensity physical activity on most days of the week.

So how is "moderate" defined?

Well, think of it as basic physical movements (e.g. walking) performed at a higher intensity or greater frequency than normal. Moderate activity involves going slightly above what you normally do during activities of daily living.

The following is a list of ways to burn more calories with physical activity:

• Walk the entire mall once or twice before shopping
• Take the stairs instead of the elevator/escalator
• Manually wash the car
• Walk around the worksite before entering the building
• Unload groceries from the car one bag at a time
• Walk around during commercial breaks
• Park the car further away
• Walk to a bathroom on a different floor
