A 2012 study published in the American Journal of Preventative Medicine found that the farther Texas residents commuted every day, the more likely they were to be overweight. Unsurprisingly, the farthest commuters were also less likely to get the recommended amount of daily physical activity. "It's not so easy to move or change your job, so if you do have a long commute it's important that you make a bigger effort to be active during the day," says lead study author Christine Hoehner, PhD. "Take walking breaks, get up from your desk often, take the stairs, and make it a priority to exercise whenever you do have time."
If you can, it might also be a good idea to try public transportation: men and women who drove to work weighed about 6.6 and 5.5 pounds more, respectively, than their peers who walked, cycled, or took trains or buses, a 2014 study in The BMJ found.
