Summer vacation is a time to take a break from the daily grind. But don’t be led down the wrong path, abandoning good nutrition and exercise. You can get away for a holiday without getting away from healthy habits. So try these ideas for staying on the trail to your goals:

• Pack snacks, especially for a flight. Airports’ and airlines’ limited food options usually come with high cost and low nutrition value. Instead, travel with your own stash. Take trail mix, fruit, carrot sticks, or high-fiber granola bars — anything healthy you can stow in your carry-on and eat on the go.

• Ration portions. Chances are you’ll be cooking less and eating out more. Enjoy guilt-free splurges by splitting meals, ordering off the child’s menu, having an appetizer plus a salad or vegetable side, or wrapping up half your dish for later.

• Have fun in the sun. While rest and relaxation should be part of the schedule, don’t forget active recreation. Instead of floating on a raft, rent a kayak. Hike or bike the local trails. Visit the sites on foot rather than bus or cab — most popular destinations offer walking tours through scenic and historic landmarks.
