Fidgeting for weight loss

This article suggests that small increases in activity during the day can add up to big changes in calories burned and weight
Their study, published in Science, did not involve deliberate exercise, but it measured - with the help of the sensors - how much people moved about naturally and spontaneously.

The heavier ones tended to sit, while the lean ones were more restless and spent two more hours a day on their feet - standing, pacing around and fidgeting. The difference translated into 350 calories a day, enough for the heavy people to take off 30 to 40 pounds a year, if they would get moving.

This makes intuitive sense to me, the question is how effectively can you increase your energy use. The leader of the studies actually put a treadmill in his office and walks at a slow pace (o.7 mph) while working at his desk. Seems crazy at first, not so much so after you think about it.

So maybe I could lose weight just by fidgeting more.
