Planning out healthy meals and snacks in advance can help you stick to your healthy eating plan. So think for a moment about what you plan to eat tomorrow. Do you need to pick any items up from the store? If so, make a list and set a reminder to stop by the grocery store. How much time will you need to set aside to prep and cook items? Check your schedule and make sure you have time for that. A little time upfront may help you avoid unhealthy choices. You may be less likely to skip breakfast. And you may also be less likely to head to the vending machine for a snack or to swing through the drive-through.
