The holidays are crazy enough, but this year you’re managing gestational diabetes on top of it. It’s easy to feel overwhelmed and confused, especially if your numbers suddenly aren’t making sense.
You may be thinking, “I didn’t even eat that much, so why did my numbers jump?” and spend hours googling what you could’ve done differently. The truth is, there are many reasons this time of year may impact your blood sugar differently- and often it’s a combination of things.
As a gestational diabetes dietitian who’s helped women navigate blood sugar all year round, I’m here to share the patterns I see most often and help you figure out what you can tweak to make a difference so you can still enjoy all the holiday cheer.
We know many factors play into blood sugar spikes, both nutrition- and lifestyle-related. It’s important to think through them honestly so you can understand why this season may be affecting you differently.
Holiday Stress
Stress directly impacts blood sugar, often raising it almost instantly. With end of the year wrap-ups, holiday shopping, family plans, and even a gestational diabetes diagnosis, who wouldn’t be feeling the stress?
When your mind, body, or nervous system feels overwhelmed, cortisol rises. Cortisol tells your body it’s in “fight or flight,” and in response, your body naturally raises blood sugar (it’s giving you the fuel to fight or flee from the perceived threat).
While your body is doing its job in trying to protect you, this is obviously not ideal for blood sugar control.
To help rein this in, you might:
- Slow down where you can
- Practice deep breathing (bonus: great for labor)
- Talk with a friend or counselor
- Set firmer boundaries to protect your peace this season
Irregular meals
Office Christmas parties, cookie baking, church potlucks, travel days, grazing while wrapping gifts- it can all throw off your meal schedule.
Your blood sugar thrives on structure, not on nonstop snacking. Ideally, most women with GDM do well eating a meal or snack about every three hours and giving their body time to rest and digest in between.
Don’t forget to begin your day with a solid breakfast! Not sure what to eat in the mornings? My GDM Breakfast Guide has balanced, blood-sugar-friendly options.
This doesn’t mean you can’t enjoy holiday foods. It just means being mindful of meal timing and avoiding the “eat all day long because it’s Christmas break” pattern your blood sugar will absolutely call you out on.
More Carb-Heavy Foods
This time of year is filled with treats and snacks you may not eat the rest of the year, and unfortunately many are higher in carbohydrates than is ideal for GDM blood sugar balance.
A few quick reminders:
- Stick within your personal carb goals for meals and snacks.
- Never eat carbs alone- always pair with a protein or fat.
- If you’re planning to have extra carb foods (Christmas cookies after dinner, for instance), consider adjusting the carbs at dinner so you’re not stacking more sugar than your body can comfortably process.
Big Dinners & Late Meals
Holiday dinners tend to be bigger, heavier, and eaten later, which is a tough combo for blood sugar. Your body is more insulin-resistant at night, and slower digestion plus a large carb load can mean higher readings.
If you know you’ll be eating late, pair carbs well, add extra protein, and go for a short walk afterward if possible (even 10 minutes makes a difference).
Less Movement
Let’s be honest- it’s cold, it’s dark early, you’re busy, you’re pregnant, and you’re tired. Of course you’re moving less.
But less movement means fewer opportunities for your muscles to help regulate blood sugar. Post-meal walks, gentle stretching, or even taking the stairs a little more often can help offset this.
Don’t aim for perfection here. Aim for what is achievable today.
Sleep Disruptions
Between stress, pregnancy discomfort, travel, time changes, and late nights, sleep often takes a hit during the holidays. Poor sleep increases insulin resistance, which can show up as wonky fasting numbers or higher post-meal spikes.
If possible, protect your sleep routine. Dim lights early, limit late-night snacks, keep your room cool, and give yourself permission to go to bed earlier if needed.
What Can You Actually Do to Improve Your Numbers During the Holidays?
Here are simple, actionable steps you can start using today:
1. Be Consistent With Meal Timing
Try to aim for:
- Eating breakfast within an hour of waking up (ideally as soon as possible)
- Meals spaced every 3–4 hours
- A balanced bedtime snack if fasting numbers tend to run high
- Avoiding “holiday grazing” that never gives your blood sugar a break
2. Use the Plate Method (Holiday Edition)
When in doubt, build your plate like this:
- ¼ protein (turkey, ham, roast beef)
- ½ non-starchy vegetables (green beans, salad, roasted carrots, Brussels sprouts)
- ¼ carbs (potatoes, rolls, stuffing: pick your favorite, not all three)
- Add healthy fats for balance (butter, gravy, olive oil, nuts)
3. Move After Meals
This is one of the most powerful tools for instantly lowering blood sugar.
Try:
- a 10–15 minute walk after dinner
- playing with kids, tidying the kitchen, or walking laps inside if it’s freezing
- standing instead of sitting when chatting after a meal
Small spurts of movement truly matter.
4. Hydrate More Than You Think
Dehydration can raise blood sugar, and the holidays are full of salty foods and sugary drinks. If you need help choosing a pregnancy-safe electrolyte supplement for extra hydration support, here’s my breakdown of the best electrolyte options for GDM.
Aim for steady water intake throughout the day, not chugging at night.
5. Prioritize Protein
Protein stabilizes blood sugar, slows digestion, and helps curb cravings.
Try adding:
- an extra serving of turkey or eggs
- a cheese stick or Greek yogurt before events
- nuts, jerky, or a protein shake if you’re running around all day
6. Choose a Smart Bedtime Snack
If fasting numbers are your pain point, this matters.
Try pairing:
- protein + a slow carb (ex: cheese + whole-grain crackers)
- full-fat Greek yogurt + a few berries
- nut butter + ½ banana

Key Takeaways
- Holiday stress, late meals, treats, and irregular routines can all affect blood sugar.
- You’re not doing anything “wrong,” your body is responding to a more chaotic season.
- A few small tweaks (meal timing, movement, pairing carbs, protein, hydration) can make a big difference.
- You can still enjoy holiday foods, you just need a little strategy behind it.
FAQs: Eating for GDM During the Holidays
Can I still enjoy dessert with gestational diabetes?
Yes! Just don’t stack multiple carb sources. Pair dessert with protein or reduce carbs at the meal beforehand.
What if my numbers are higher even when I’m doing everything “right”?
It happens. Stress, hormones, poor sleep, and normal third-trimester insulin resistance all play a role. Look for patterns, not perfection.
Is it okay to have a late Christmas dinner?
Yes, just be mindful of portions and pairings. A short walk afterward helps significantly.
What if I’m traveling?
Pack protein-forward snacks, stay hydrated, and try not to go too long between meals.Should I skip carbs altogether?
No! Your body and your baby need carbs. It’s about the right amounts and strategic pairing, not elimination.
