Worried that you’re going to bring back extra pounds along with your souvenirs? Don’t be; VIV’s diet doctor tells you how to beat holiday weight gain.

Don’t crash diet. If you fast in the weeks before your trip, you’ll just end up slowing your metabolism, which leads to rapid weight gain when you start eating normally during your trip.

Stroll around the airport. Nix the moving sidewalks and stroll laps around the terminal when you have a roller bag. Window-shop while you kill time. Anything to make up for the calories you won’t burn sitting on a plane.

Bring healthy snacks for the flight. Nuts, protein bars or fruit are great choices. Or eat a satisfying meal, such as a sandwich or salad, prior to departure.

Drink water. Hunger and thirst can feel similar, and since air travel dehydrates you, drink plenty of water before and during the flight. And minimize alcohol and caffeine consumption on travel days.

Plan snacks ahead. If your hotel has a fridge, find a local market and get some cottage cheese and fruit to snack on. Bring nuts, fruit or energy bars when you go sightseeing.

Live a little! Feel like having dessert or wine? Skip the bread and potatoes. Splurge on regional food items and house specialties, not chips or junk food.

Skip sugary beverages and cocktails. Margaritas and daiquiris contain up to 500 calories and can easily pack on 1-2 pounds a week. Is it really worth it? Treat yourself to one on your first day; then avoid drinking your calories for the rest of the trip.

Stay true to your eating plan. Stick with protein-based meals and snacks, high-quality carbohydrates and reasonable portions most of the time.

Get extra physical activity each day. Swim, snorkel, bike the countryside, go for walks after dinner, go dancing.

Back home, go food-shopping ASAP. It’s important to get back on track with your nutrition program right away. By filling the fridge with healthy food as soon as you return, it guarantees you’ll stick to your plan.
