Vacation is certainly a respite from your usual work routine and environment, but do not abandon your healthy eating and exercise habits.
Many vacations start out with a long car ride.
Take a cooler and pack it with diet drinks, water, fruit, sandwiches or even a picnic lunch. Do not confine yourself in a car loaded with cookies, candy, chips and sugary drinks. Consider stopping at a park, unloading the kids and food, and moving around during your meal break. When you stop for a restaurant meal, choose a place that offers more food choices than fried foods and shakes. A good sign is a restaurant in which you can actually order a vegetable or salad with your meal.
