Published: 18 November 2025 | Reading time: 16 minutes

Traveling With Mounjaro: Logistics

Packing Your Pen

Hand luggage (NEVER check baggage):

• Mounjaro pen in original packaging
• Prescription or letter from prescriber (proves it's yours)
• Small cool bag (not essential but helpful)
• Sharps container (small travel one)

Airport security:

• Declare you're carrying medication with needles
• Show prescription
• They'll wave you through (diabetes pens common, they're used to it)

Storage at Destination

Unopened pens:

• MUST be refrigerated (2-8°C)
• Hotel mini-fridge perfect
• If no fridge: Ask hotel to store in their fridge (medical necessity)

Opened/in-use pen:

• Can be room temperature up to 21 days
• Keep out of direct sunlight
• Bathroom cabinet or bedside drawer fine

Injection Timing While Away

Same day, flexibility on time:

• If you normally inject Sunday 9am: Inject Sunday anytime that day
• Easier to do morning (before breakfast, before day's activities)
• Set phone alarm so you don't forget

Time zone changes:

• 1-3 hours difference: No adjustment needed, inject as normal
• 4+ hours: Inject within 24 hours of usual time (slight flexibility OK)

All-Inclusive Holidays: The Mounjaro Paradox

You've paid for unlimited food and drink. Your appetite is suppressed. Feels wasteful. Let's reframe.

The Mental Shift

Old thinking: "I paid £1,500 for all-inclusive! Must eat and drink my money's worth!"

New thinking: "I paid for HOLIDAY, not just food. The value is: beach, pool, relaxation, not eating till I'm sick."

Buffet Strategy

Breakfast buffet:

• 2 scrambled eggs (16g protein)
• 2 strips bacon
• Small portion fruit
• Black coffee/tea
• You'll be satisfied. The 8 pastries you used to have? Don't even appeal.

Lunch buffet:

• Small plate: 60% protein (chicken, fish), 40% salad
• One trip only
• Skip dessert (genuinely not hungry for it)

Dinner buffet:

• Choose 3 things you REALLY want
• Small portions of each
• Savor them
• Stop when full (70% of plate likely)

What You'll Notice

• Other guests stacking plates HIGH - you used to be them
• Going back for seconds/thirds - you don't need to
• Eating till uncomfortable - you can't physically do this anymore
• You're enjoying holiday MORE (not food-obsessed, not bloated/uncomfortable)

Restaurant Dining Strategy

Ordering Smart

Starters:

• Order a starter as your main (portion sizes more manageable)
• Or share a starter with partner
• Protein-rich choices: Prawns, chicken skewers, calamari

Mains:

• Grilled fish/meat (not breaded - lighter)
• Ask for vegetables instead of chips
• Sauce on the side (you'll use less)
• Accept you won't finish. That's OK. You've paid for the experience, not to clear the plate.

Dessert:

• Share one between 2-4 people
• 3-4 spoons and you're satisfied
• Or skip entirely (you won't want it after main)

Handling "Wasted" Food

Pre-Mounjaro you: Finish everything (paid for it, can't waste it)

Mounjaro you: Leave half the plate

Mental reframe:

• "Wasting" food on plate < "wasting" health by overeating
• The food is "wasted" whether it goes in bin or in you when you're full
• You're paying for dining experience, not calorie consumption contest

Doggy Bags (Embrace Them)

• UK culture: Slightly awkward to ask
• European/US: Totally normal
• Ask anyway. "Could I have this to take away please?"
• Lunch tomorrow sorted

Alcohol on Holiday

Beach bar. Poolside cocktails. Dinner wine. It's TEMPTING.

The Mounjaro + Alcohol Reality

• Tolerance MUCH lower: 2 drinks feels like 4-5
• Why: Delayed gastric emptying (alcohol sits in stomach longer, absorbed more slowly but HITS harder)
• Hangover worse: Dehydration + Mounjaro dehydration = brutal next day

Safe Holiday Drinking Strategy

Rule 1: Half your normal intake

• Used to drink 4 cocktails? Have 2 maximum.
• Used to have bottle of wine? Share with partner.

Rule 2: Hydration obsession

• 1 alcoholic drink = 1 large glass water immediately after
• Drink pint of water before bed
• Electrolytes in morning (Dioralyte)

Rule 3: Pace yourself

• 30 minutes minimum between drinks
• Eat BEFORE drinking (protein-rich meal)
• Switch to soft drinks after 2 alcoholic ones

Activity & Movement on Holiday

Don't Stress About "Exercise"

• Holiday is rest/recovery
• No need for hotel gym
• Natural movement counts: Swimming, walking, sightseeing

Aim For:

• 8,000 steps daily (exploring, beach walks)
• Swimming 20-30 min (fun, not exercise)
• Active excursions (hiking, snorkeling, cycling)

What You'll Notice

• Can do MORE than previous holidays (lighter, fitter)
• Less exhausted by walking around all day
• Breathing easier (if you had sleep apnea, it's improved)

Weight Expectations During & After

During Holiday (1-2 Weeks)

Realistic outcome:

• Best case: Lose 0.5-1kg (continued progress)
• Most common: Maintain weight (±0.5kg)
• Acceptable: Gain 1-1.5kg (water/food volume, not fat)

Don't weigh yourself daily on holiday. Stress-inducing. Weigh once before leaving, once when home.

Post-Holiday "Gain"

You return home 1.5kg heavier. DON'T PANIC.

• Water retention (salt, carbs, travel)
• Food volume in system
• Maybe 0.5kg actual fat (if you overindulged)

What happens next:

• Back on normal routine
• Strict protein focus
• Hydration up
• The 1.5kg drops off in 5-7 days

Should You Skip Injection to "Enjoy" Holiday More?

Every year, people consider: "Skip my dose so I can eat more on holiday."

DON'T DO THIS.

Why It Backfires

• Day 1-2 post-skip: Appetite returns gradually
• Day 3-5: RAVENOUS. Eat like pre-Mounjaro. Gain 2-4kg.
• Day 6-7: Feel bloated, uncomfortable, regretful
• Restart after holiday: Side effects return (like Week 2 again)

Net result: Ruined holiday (felt sick from overeating), gained weight, suffered restarting. NOT WORTH IT.

Better Approach

• Stay on Mounjaro
• Appetite naturally controlled
• Enjoy food in sensible portions
• Feel GOOD during and after holiday
• No restart misery

Cuisine-Specific Strategies

Mediterranean (Greece, Spain, Italy)

Great for Mounjaro:

• Grilled fish/octopus (high protein)
• Greek salad (filling, low cal)
• Mezze plates (small portions of variety)

Moderate:

• Pasta (small portion, share)
• Pizza (2-3 slices max, you'll be full)
• Bread/olive oil (easy to overdo - limit)

Asian (Thailand, Vietnam, Bali)

Great:

• Pho (protein-rich, broth-based)
• Grilled meats (satay, BBQ)
• Stir-fries (protein + veg)

Watch:

• Rice portions (massive servings typical - eat ⅓)
• Deep-fried (spring rolls, tempura - heavy)
• Sweet sauces (sugar-heavy)

American (USA holidays)

Great:

• Steaks (high protein)
• BBQ (meat focus)
• Burgers (eat half, skip fries)

Challenge:

• MASSIVE portion sizes
• Immediately ask for doggy bag when food arrives
• Put half in box BEFORE eating (prevents overeating)
