We get it-trying new foods, especially local specialties-is major vacation fun. But a study published in the journal Physiology & Behavior recently found that most travelers came home with an unwanted souvenir-about one -extra pound-and it stuck around for six weeks after the trip. While it may not sound like much, it can be avoided by trying these smart strategies to keep off any extra vacation weight.

Drink Water to Lose Weight: An additional 1 to 3 cups of water may help you slash 70 to 200 calories from your daily diet, says research from the University of Illinois at Urbana-Champaign. This is especially important when you're lounging on the beach because dehydration can often masquerade as hunger. Pack your favorite water bottle and be sure to order water when you're out to eat on vacation.

Try Tropical Fruit: If you're doubling up on dessert (at lunch and dinner), replace one sugary treat with local fresh fruit that you don't normally get at home. Snacking on fruit is always a good idea-vacation or not-because fruit contains fiber, which can help you stay full and feel satisfied.

Beat the Buffet: Before you start serving yourself at the all-you-can-eat buffet, do a lap to survey the situation. Cornell University researchers found that the slimmest eaters at a buffet browse all the options first. This strategy helps you figure out what you really want to try-and what you're OK skipping-before it all ends up on your plate.
