One of the changes we work on with our clients is no eating in the car, because it’s nearly impossible to really eat mindfully while driving. Also, many dieters do secret eating in the car, so eliminating eating while driving curbs that. It’s helpful to remember that, even if you’re hungry, you can ALWAYS wait until you reach your destination to eat. You never HAVE to eat in the car. You may want to, but you never have to.
