Cut the cars along with the carbs?

This study from the University of Illinois approached obesity interventions from a new angle, suggesting that perhaps reducing daily automobile travel can be as effective as restricting calorie intake. A multivariable model predicting BMI from calories consumed and miles driven projects that if adults drove just one mile less each day, this decrease could have significant long-term impacts on the national average BMI. So when it comes to weight loss, even small changes in our daily activity level could have big implications.
