So Christmas is over but the cookies  and cakes are still staring at you!

Have you started to think about  your New Year’s Resolution yet? For many of us,  it will mean a renewed interest  in diet and exercise.

A new study in the  journal Preventive Medicine  suggests there’s something else  you should add to your list  to find success on the scale!

Researchers at the University of Illinois  looked at government data  covering three specific areas —  annual BMI,  average daily caloric intake and the number of vehicle miles driven. Using advanced mathematical models,  they discovered obesity,  calories and automobile travel are related!

The data showed  the more we Americans ate over the years  and the more we drove,  the higher our Body Mass Index.

If you subtract just 1 mile of daily driving  and convert to walking instead, you’d lose about half a pound  over 6 years.   In comparison,  cutting 100 calories a day  would help you drop about  a third of a pound over 3 years.  Bottom line:  move more, eat less and park the car.  It could add up to better health in 2013.
