Fasting on vacation, while traveling, and during holidays
Vacation, business trips, and holidays are the three situations in which the window most often falls apart. Not because it is impossible to maintain the pause, but because people try to maintain it as they do at home—and lose out to flight schedules, hotel breakfasts, and festive meals. The practical approach is different: the window shifts rather than being canceled, meals remain close together, and one festive dinner does not turn into a week of “I’ve already blown it anyway.”

Travel: plane, train, car
Travel is the ideal time for a pause. You sit, expend little energy, and the food on planes and at gas stations is the worst thing you can eat. The simplest plan: have a substantial meal before setting out; on the way, drink water, have coffee and salt, and have your first proper meal once you arrive. A 4-6-hour flight fits entirely within the pause.
On long flights across time zones, the pause also helps you adjust: food is a strong signal for your internal clock, and having your first meal in the “morning” of the new location helps your body adapt faster than eating according to the old time. So on the first day, it’s best to set the window according to local time right away rather than trying to “stretch” your home-time window.
Salt matters more while traveling than at home: dry air on the plane, little water, lots of coffee. A glass of water with a pinch of salt before boarding and salty mineral water once you arrive eliminate half of that “travel” exhaustion. More details — salt, water, and electrolytes during the pause.
If you’re renting an apartment, the method’s food list fits into a single basket: what to look for in an unfamiliar store — the approved foods list.
“Breakfast included” doesn’t mean you have to eat it at 7:00. If your eating window at home opens at 11:00, but breakfast ends at 10:30, go at 10:00 and eat it as your first meal: eggs, bacon, cheese, vegetables, nothing from the pastry basket. Dinner — at 18:00-19:00. These are two substantial meals, with a 9-hour window.
The simplest option: buy eggs, cheese, avocado, greens, and meat for the grill — and live as you do at home. The list from the method fits in one basket. What to look for in an unfamiliar store — the white list of foods.
Here, it’s not the food that falls apart, but the schedule: breakfast at 8:00 “because everyone is eating”. Say in advance that you eat later, and ask them to leave a plate for you. Coffee at the shared table in the morning is fine; it isn’t food.
Food is available 16 hours a day, and that is the main trap. Choose two times a day — a late breakfast and dinner — and go to the restaurant only at those times. In between — the pool, the sea, water. Snacks at the bar are the most common reason a vacation adds 3 kg.
Holidays and feasts: one dinner is one dinner
A festive dinner according to someone else’s rules is not a slip-up. A slip-up is when afterwards you decide that your routine is broken and eat everything for the next three days. One meal outside your window and with extra carbs costs one day: in the morning, water with salt, coffee, your window as usual—and everything is back to normal. The same topic is covered in what to do after a slip-up.
You can make the dinner itself smarter without any stress. Start with protein and vegetables—meat, fish, salads, cheese; leave bread, side dishes, and sweets for the end, when you are already full. Research shows that the order in which you eat reduces the glucose spike, and this works at a festive table too. For alcohol, choose dry wine or spirits without sweet mixers, and have a glass of water for every drink.
And most importantly: don’t come to the feast after 20 h of fasting “to make up for it.” A substantial first meal during the day means that in the evening you will choose food with your head, not out of hunger. How to put that meal together—the first meal after a pause.
What to do with the window on different trips
| Situation | Window | Meals | Main rule |
|---|---|---|---|
| Business trip 2-3 days | as at home, shift up to 1 h | 2-3 | dinners with colleagues — within the window, no snacks at meetings |
| Vacation in the same time zone | shift by 1-2 h to match the rhythm of rest | 2 | late breakfast and dinner, water in between |
| Flight across 5+ time zones | immediately according to local time | 2 | first meal in the local “morning”, no food on the plane |
| Holidays at home | as usual | 2-3 | holiday dinner — within the window, the next day — as usual |
| Hike, active tour | wider, 10-12 h | 3 | a lot of energy is expended, do not undereat |
No snacking. Consume the entire diet over two or three meals until comfortably satiated.
How not to gain weight on vacation without counting anything
Vacation weight gain is almost never about eating at restaurants, but about what happens between restaurants: ice cream on the promenade, nuts with beer, “trying the local food” six times a day. Cut out the snacks, and two restaurant meals a day, even with dessert, barely move the scale.
The second factor is water and salt. Heat, the sea, and alcohol make the body lose sodium faster than at home, while the brain interprets a lack of sodium as hunger. Salty mineral water on vacation is not a whim.
The third factor is movement. On vacation, people walk 15-20 thousand steps, which is often more than they do at home with workouts. No additional sessions are needed during a break: a walk in the morning before your first meal already counts as fasted training, only more pleasant.
Getting back to your eating window after vacation is easy if there were no snacks. If there were, waves of hunger will come at “vacation” times for 3-5 days, and that is normal: find out why in the article about hunger during the fasting window.
Travel kit
Salt
A packet or a small jar. A pinch in water in the morning and after the flight.
Nuts and cheese
Not for snacking, but as a safeguard: if the first meal is delayed by three hours, a handful of macadamias and a slice of cheese are better than a kiosk bun.
Cream for coffee or black coffee
Single-serving cream isn’t available everywhere. Black coffee during a break is fine too.
One rule
Not “stick to 16/8 at any cost,” but “two substantial meals, nothing in between.” It withstands any schedule.
What Disrupts Your Routine While Traveling
- Eating on the plane just because food is served
- Having breakfast at 7:00 because it is included
- Snacking on “local” food between meals
- Coming to a celebratory dinner after a 20-hour fast
- Considering one dinner the end of your routine and eating everything for the rest of the vacation
- Drinking too little water and no salt at all in the heat
Frequently asked questions
Should I keep the eating window while on vacation at all, or give myself a break?
The window isn't work you need a break from. But you can keep it more gently: 12/12 or 14/10, two substantial meals, no snacks. Returning to 16/8 afterward is much easier than starting from zero.
How should I handle breakfast at the hotel if it is served until 9:30?
Either go toward the end and have it as your first meal, shifting dinner earlier, or skip it. Coffee at breakfast is fine, but not food, if your window opens later.
A celebration lasts three days in a row. What should I do?
One meal a day is festive, and the second is a regular meal of protein and vegetables. No snacks between them. Three festive dinners take three days, not three weeks.
How many days does it take for the routine to return after vacation?
If there were no snacks, the routine never left. If there were, allow 3-5 days for the hunger waves to return to the window. There is an article about hunger during the pause.
