First of all, despite the common complaint of packing on five-plus pounds while on a cruise, you can’t actually gain that much weight in the span of a typical vacation. If a person had any change in actual body mass (as opposed to water weight, which we’ll discuss shortly), it would likely only be about a pound during a weeklong vacation, says Ellen Albertson, PhD, RDN, a psychologist, registered dietitian, and nutritionist who founded the online program Smash Your Scale.
Plus, that small gain wouldn’t last long. “The difference in eating [on vacation] is not going to have any impact once you go back to day-to-day living,” explains Melainie Rogers, MS, RD, registered dietitian, nutritionist, and founder of Balance Eating Disorder Treatment Center in New York City. “Your weight will naturally readjust itself over the next few weeks once you’re home, without any dieting,” she says.
These forms of water retention are all natural phenomena and there’s nothing you need to do to combat them. As long as you don't have cardiovascular or kidney problems, or a rare glycogen storage disorder, your body can handle these fluid fluctuations and will return to normal all on its own in a matter of days.
What about fitness — if you take a vacation from your usual routine, will you return home totally out of shape? Not likely. “People tend to be slightly more active on vacation,” says Rogers. “If they’re at the beach, they’ll tend to take a walk on the beach; or if they’re sightseeing, they’ll be walking a lot more.” Even on the off chance that you're doing nothing but floating in a pool for two weeks, fear not: Research has shown that one or two weeks of inactivity won’t affect your fitness level significantly and it would take a month or more to lose a significant amount of strength and endurance. Elite athletes who have specialized training for certain sports may experience declines in strength sooner, but still nothing very meaningful in two weeks or less.
Want to approach vacation in a more balanced way? Try these tips:
Rogers explains that restricting yourself and then overindulging can keep you locked in a cycle of black-and-white thinking about food that can continue well after the trip is over. “If you diet before a vacation, you are putting yourself at risk of overeating and disordered eating while you’re away and when you get back,” she says. Instead, practice living in the gray areas — choosing some foods for pure pleasure and others for nutrition.
Start paying attention to your hunger and fullness cues.
Before the vacation, try to allow yourself to eat when you’re hungry and stop when you’re full. This practice is part of a method called intuitive eating, which has been shown to help reduce disordered eating behaviors and is associated with lower body weights and less weight gain than dieting. “Your body is really good at maintaining a stable weight, so if you listen to your hunger and satiety signals you should be fine,” says Albertson. She cautions that if you have a lot of trouble connecting with your hunger and fullness signals, you may have some deeper work to do — and vacation is probably not the best time to do it. “Try to address those issues before going on vacation, so that you can legalize food when you’re away,” says Rogers. (If you think you may have disordered eating or an eating disorder, seek help from professionals experienced in treating them.)
Take pleasure in food.
“There’s a very normal mentality on vacation of wanting to treat yourself, and I think that’s natural and healthy,” says Rogers. Try to relish those treats. “If you want to have that decadent dessert, give yourself full permission and completely engage in it, and enjoy yourself,” says Albertson. “As soon as we tell ourselves ‘don’t eat this, don’t eat this’ is when we see people binge on something that they didn’t really want because they denied themselves [the thing they did want].”
Avoid the scale.
If you’re just too tempted by the one in your hotel room, ask housekeeping to take it away.
