Christmas Dinner Strategy

The big one. December 25th, 2pm, family gathered, table groaning with food.

Your Plate Composition

The Eating Timeline

12-1pm: Pre-Dinner Snacks

• Crisps, nuts, cheese straws appearing
• Your strategy: Have 2-3 items. Satisfies social nibbling, doesn't fill you up pre-dinner.

2pm: Dinner Served

• Take smaller portions than you think you need
• You can always get seconds (you won't, but psychologically easier to take less initially)
• Eat SLOWLY (everyone's chatting anyway)
• Protein bites first, then veg, then carbs

3pm: Pudding

• 30-45 min gap since main (you need this - stomach still processing)
• 3-4 spoons Christmas pudding or 1 small slice pie
• Dollop of cream/custard
• You'll be DONE after this

What NOT to Do

• ❌ Skip breakfast thinking "save appetite for dinner" (makes nausea worse, you'll eat less not more)
• ❌ Force yourself to finish plate (you're full at 70%? Stop.)
• ❌ Accept "just one more potato!" pressure (you're full, that's OK)
• ❌ Feel guilty about leaving food (your health > their cooking validation)

Handling Family Comments

This is the hard part. Food = love in many families. Eating less = perceived rejection.

Comments You WILL Hear

"Why aren't you eating?"

• Response: "I am eating! This is delicious, I'm just full quickly at the moment."
• Tone: Light, positive, redirect to food quality not quantity

"Are you on a diet? It's Christmas!"

• Response: "Not a diet, working with doctor on health goals. I'm actually enjoying Christmas more this year!"
• Deflects to medical authority, positive frame

"You've hardly touched your plate!"

• Response: "I've had plenty! Really enjoyed it. I'm just full." (Smile, mean it.)

"I made this specially for you!"

• Response: "It's LOVELY. I'm savoring it. Just can't eat as much as I used to."
• Acknowledges their effort, honest about capacity

"One more won't hurt!"

• Response: "Genuinely couldn't fit it in! Save some for me for Boxing Day?"
• Decline without rejection

For Close Family (If You Want to Be Honest)

"I'm on medication that helps with appetite control. It's been amazing for my health, but it means I eat smaller portions. I'm still enjoying everything, just less of it. Please don't worry or push food on me - I promise I'll tell you if I'm hungry!"

Most families respect medical explanations.

Office Christmas Parties

Buffet table. Open bar. Drunk colleagues. Different challenge.

Buffet Navigation

Survey first, eat second:

• Walk the full buffet before taking anything
• Identify protein options (chicken satay, prawns, cheese)
• Spot the few things you ACTUALLY want

Your plate strategy:

• Small plate (if available - limits portion size naturally)
• 50% protein (mini quiches, cocktail sausages, salmon blinis)
• 30% veg/salad (if present)
• 20% carbs/treats (couple of crisps, mini Yorkshire pudding)

The reality: You'll eat half this plate, spend 45 minutes doing so, nurse one drink. That's fine. You're there for colleagues, not food.

Alcohol at Office Parties

CRITICAL: Mounjaro + alcohol = you get drunk FAST.

Why:

• Delayed gastric emptying (alcohol sits in stomach longer)
• Absorbed more slowly but hits harder
• 2 glasses wine = 4 glasses feeling

Strategy:

• Drink 1: Have it, enjoy it, pace yourself (30 mins minimum)
• Water break: Full glass water between alcoholic drinks (non-negotiable)
• Drink 2: Probably your limit if you want to stay professional
• Drink 3+: Only if you're OK with being drunk (not recommended for work events)

Multiple Parties/Events Strategy

Modern Christmas = 5-8 events minimum (work party, friend gatherings, family dos).

Energy Management

You're on Mounjaro. Fatigue is real.

• Prioritize: Which 3 events MATTER most? Attend those fully. Others = brief appearance OK.
• Early exit strategy: "Got to get home to the dog!" / "Early start tomorrow!" (prepare excuse before going)
• Rest days: Between big events, take a day home in PJs. Your body needs it.

Food Cumulation Problem

5 parties = 5 meals of rich food in 2 weeks.

On Mounjaro, this is actually fine. You're eating small portions at each. Total weekly calories still lower than normal. BUT:

• Rich food (cream, cheese, pastry) can worsen nausea
• Alcohol cumulation (2 drinks x 5 nights = 10 drinks/week) affects liver
• Disrupted routine (meal timing, protein intake) can stall weight loss

Counter-strategy:

• Non-event days: STRICT protein focus (100g+, simple meals)
• Hydration obsession: 3L water daily, especially day after drinking
• Limit to 3 "drinking events" per fortnight maximum

Dealing with Food Gifts

Selection boxes. Chocolate tins. Homemade cookies. They WILL arrive.

Accepting Graciously Without Eating It All

The gift: Tin of Quality Street from mother-in-law.

Old you: Eat entire tin in 3 days, feel awful, gain 2kg.

Mounjaro you:

• Day 1: Have 2 chocolates after dinner (genuinely satisfy sweet craving)
• Day 2-7: 1-2 chocolates daily
• Week 2: Tin still 70% full, getting bored of them
• Action: Take to work, share with colleagues, they disappear

Homemade treats:

• Freeze them (seriously - homemade cookies freeze brilliantly)
• Defrost 2 at a time as needed over January/February
• Giver feels appreciated, you don't binge

Food Gifts You Can Eat

If people ask "What do you want for Christmas?":

• High-quality protein snacks (biltong, fancy jerky)
• Nice tea/coffee selection
• Cooking ingredients (olive oil, spices, vinegars)
• Kitchen gadget (air fryer, spiralizer)

The Real Goal: NOT GAINING Weight

Let's reframe expectations.

Typical UK Adult Christmas

• Weight gain: 3-5kg between Dec 1 - Jan 5
• Cause: Excess calories (500-1000 cal/day surplus), alcohol, reduced activity
• Outcome: Enter January heavier than December, needs losing AGAIN

Your Christmas on Mounjaro

• Weight change: -1kg to +1kg (essentially maintenance)
• Cause: Appetite suppressed, small portions, natural calorie control
• Outcome: Enter January at SAME weight or lighter - ready to continue progress

NET DIFFERENCE: 4-6kg swing.

That's HUGE. You're not losing ground. Everyone else is. Come January, you're ahead.

Don't Skip Your Injection

Every year, people think: "I'll skip my injection Christmas week, enjoy food more, restart Boxing Day."

DON'T.

What Actually Happens If You Skip

Days 1-3 after skipping:

• Appetite returns (gradually, then suddenly)
• By Day 3, you're STARVING
• Christmas dinner = you eat like pre-Mounjaro (massive portions, seconds, thirds)

Days 4-7:

• Regret sets in (bloated, uncomfortable, gained 2-3kg)
• Restart injection Boxing Day
• Side effects return (nausea, fatigue) - WORSE than if you'd stayed consistent

Days 8-14:

• Adjustment period again (like Week 2 originally)
• Ruined first 2 weeks of January

Was "enjoying food more" worth it? No.

Stay Consistent

• Inject on your normal day (even if it's Christmas Day - takes 30 seconds)
• Appetite stays controlled
• You STILL enjoy Christmas food (small portions of delicious things > massive portions and regret)
• No restart misery in January

Setting Up January Success

Christmas ends January 5th (Twelfth Night). What then?

Post-Christmas Reset

January 6th onwards:

• Back to strict protein routine (100g+ daily)
• Hydration back up (3L daily)
• Movement increases (10k steps, gym if you go)
• Alcohol stop (or minimal - 1 drink weekly max)

Expected: Any small Christmas gain (+1-2kg) drops off in 7-10 days. Back on track.

Don't Do "New Year Detox"

• No juice cleanses (you need protein)
• No "making up for Christmas" by eating 800 cal/day (dangerous with Mounjaro)
• Just return to normal Mounjaro routine (1,200-1,600 cal, high protein)

Enjoy Christmas, Stay On Track
