Christmas puts blood sugar to the test in a different way than Thanksgiving. The meals are spread over days, the sweets are everywhere, parties and gifts of food keep arriving, and the drinks are sweet. Skipping the holiday is not the goal. This guide gives you a plan for the dinner plate, the cookie tray, the party drinks, travel days, and the morning after.
Quick answer: Use a 9-inch plate: half non-starchy vegetables, a quarter protein, a quarter carbohydrate foods. Be selective, because you do not have to try everything. Know where the carbohydrate hides (candied yams, pies, cookies, eggnog, cocoa, cider), take a short walk after the big meal, check your glucose more often when your routine changes, and keep your normal meals instead of skipping them. Do not change medicine doses on your own. This is education, not medical advice.
Why Christmas is hard on blood sugar
The holiday stacks several things at once. Meals can run late or move to odd hours. Sweets arrive as gifts, at the office, and on every counter. Drinks such as eggnog, hot cocoa, cider, and mulled wine carry real carbohydrate. Travel and visiting change your routine, and many people exercise less. The American Diabetes Association’s Diabetes Food Hub lists the same pressure points in its 6 Tips for a Happy, Healthy Holiday with Diabetes: plan for meals served at unusual times, be selective, bring a vegetable dish, plan snacks, stay active, and check your blood glucose more often when your routine changes.
Build your holiday dinner plate
The same Diabetes Food Hub page recommends a nine-inch plate: half non-starchy vegetables, one quarter protein, and one quarter carbohydrate. It also says to skip carbohydrate-heavy foods you eat all year and save room for the special holiday dishes.
| Part of the plate | What goes there | Notes |
|---|---|---|
| Half | Green beans, Brussels sprouts, salad, roasted carrots or broccoli | Roasted or steamed beats creamed, glazed, or fried |
| One quarter | Turkey, ham, beef, or another protein | Plain meat has no carbohydrate to count, but glazes and gravies add some |
| One quarter | One or two starchy favorites | Pick the dishes you look forward to all year, not everything on the table |
| On the side | Water, unsweetened tea, sparkling water | Liquid sugar adds carbohydrate quickly |
If you are bringing a dish, bring a non-starchy vegetable, as the Diabetes Food Hub suggests. Then you know at least one thing on the table fits your plan.
What is in the typical dishes
The tables below use published carbohydrate counts from Breakthrough T1D Canada’s Holiday Season Carb Counting page (last modified December 16, 2022), which credits Beyond Type 1 for the counts, with a few drinks and desserts from the Breakthrough T1D and EatWellExchange Christmas Carb Count flyer (no date shown). These are approximate. The source says portion sizes may vary and counts need to be adjusted accordingly. Recipes, brands, and portion sizes change the numbers, and different lists disagree on the same food.
Mains and sides
| Food | Serving as listed | Carbs (approx.) |
|---|---|---|
| Mashed potatoes | 1 cup | 30 g |
| Roasted potatoes | 1 cup | 28 g |
| Candied yams | 1/2 cup | 45 g |
| Sweet potato casserole with marshmallows | 1/3 cup | 30 g |
| Stuffing | 1/2 cup | 20 g |
| Cranberry sauce | 1/4 cup | 25 g |
| Dinner roll | 1 roll | 20 g |
| Cornbread | 1 piece | 28 g |
| Glazed carrots | 1/2 cup | 25 g |
| Green beans | 1/2 cup | 4 g |
| Brussels sprouts | 1/2 cup | 4 g |
Plain turkey, ham, beef, and chicken are listed at 0 grams. Glazes, sweet sauces, and breading add carbohydrate, and no count for a honey-glazed ham was available in these lists, so check the label or ask the cook. Gravy is listed at about 5 grams for half a cup.
Desserts
| Dessert | Serving as listed | Carbs (approx.) |
|---|---|---|
| Pecan pie | 1/8 slice | 60 g |
| Minced meat pie | 1/8 slice | 55 g |
| Meringue pie | 1/8 slice | 50 g |
| Apple pie | 1/8 slice | 45 g |
| Pumpkin pie | 1/8 slice | 35 g |
| Gingerbread (cake or loaf) | not specified | 35 g |
| Christmas (plum) pudding | 2 oz | 30 g |
| Fruitcake | 1/8 slice | 26 g |
| Cheesecake | 1/6 slice | 20 g |
| Vanilla ice cream | 1/2 cup | 16 g |
The pattern is the same as at Thanksgiving: one slice of pecan pie (60 grams) can carry more carbohydrate than the whole dinner plate of non-starchy vegetables, meat, and gravy combined. Sweet potato dishes made with marshmallows and candied yams carry more than plain roasted potatoes. For other pies, see our Thanksgiving guide, which uses a different published list and gives slightly different counts, a good reminder that every list is an estimate.
A worked example: two plates, same table
Here are two plates built from the numbers in the tables above. Half of the 30 grams listed for a cup of mashed potatoes is 15 grams.
| Plate A: everything | Carbs | Plate B: planned | Carbs |
|---|---|---|---|
| Ham | 0 g | Ham | 0 g |
| Mashed potatoes, 1 cup | 30 g | Mashed potatoes, 1/2 cup (half of 30 g) | 15 g |
| Candied yams, 1/2 cup | 45 g | Stuffing, 1/2 cup | 20 g |
| Stuffing, 1/2 cup | 20 g | Green beans, 1/2 cup | 4 g |
| Cranberry sauce, 1/4 cup | 25 g | Brussels sprouts, 1/2 cup | 4 g |
| Dinner roll, 1 | 20 g | Gravy, 1/2 cup | 5 g |
| Gravy, 1/2 cup | 5 g | Sugar cookies, 2 | 22 g |
| Eggnog, 1/2 cup | 30 g | Water or unsweetened tea | 0 g |
| Pecan pie, 1/8 slice | 60 g | ||
| Total | 235 g | Total | 70 g |
Check Plate A: 30 + 45 + 20 + 25 + 20 + 5 + 30 + 60 = 235 grams. Check Plate B: 15 + 20 + 4 + 4 + 5 + 22 = 70 grams. Plate B is 165 grams lower and still has stuffing, mashed potatoes, gravy, and a sweet treat. The choice was which starchy foods to take, not whether to enjoy dinner. Whether either plate fits you depends on your own carbohydrate range, which is a question for your care team.
Cookie trays, office parties, and cookie exchanges
Cookies are the hardest part of December because they appear every day. Published counts for typical servings are below. The key word is typical: a bakery cookie can be several times the size of the one a list assumes, and the counts for a whole tray vary with the recipe.
| Treat | Serving as listed | Carbs (approx.) |
|---|---|---|
| Ginger snap cookies | 4 (1 oz) | 23 g |
| Sugar cookies | 2 | 22 g |
| Shortbread cookies | 4 (1 oz) | 21 g |
| Chocolate chip cookies | 2 | 20 g |
| Peanut butter cookies | 2 | 20 g |
| Rugelach | 1 piece (1 oz) | 17 g |
| Meringue cookies | 6 | 15 g |
| Candy cane | 1 | 15 g |
- Decide before you walk in. Choose one or two treats you actually want instead of tasting everything. The Diabetes Food Hub tip is the same: you do not have to sample everything that is offered.
- Eat sweets after real food. Having some protein and vegetables first beats eating cookies on an empty stomach. Some small studies suggest that eating vegetables and protein before carbohydrates may lower the post-meal rise, but the effect varies between people, so treat it as an experiment you can check with your own readings.
- Ask about timing and appetizers. If the meal will be late or the appetizers are fried, the Diabetes Food Hub suggests asking the host and bringing a small snack such as a few pieces of low-fat cheese, or bringing raw vegetables.
- At a cookie exchange, bring a recipe you are comfortable with, bake smaller cookies if you are the baker, and take home a few instead of a full box.
- Do not make cookies the only thing in the day. A sweet treat on its own and a late meal is a common recipe for a rise and a crash.
Holiday drinks
Drinks are easy to overlook, and several are close to a dessert. The counts below come from the same two lists.
| Drink | Serving as listed | Carbs (approx.) |
|---|---|---|
| Eggnog | 1/2 cup | 30 g |
| Hot cocoa made with milk | 1 cup | 30 g |
| Hot cocoa made with water | 1 cup | 15-20 g |
| Spiced apple cider (non-alcoholic) | 1 cup | 30 g |
| Mulled wine | 1 cup | 25 g |
| Coquito | 4 oz | 25 g |
| Wine, red or white | 5 oz | 4 g |
| Champagne | 5 oz | 3 g |
| Regular beer | 12 oz | 12 g |
| Spirits, plain | 1 oz | 0 g |
Two cautions. The lists disagree in places: one older list shows a full cup of eggnog at about 60 grams, which matches the 30 grams per half cup above, and one lists regular beer at 12 grams for 5 ounces while the flyer lists 12 grams for 12 ounces, so treat beer counts as a range and check your own bottle or can. Second, alcohol has effects beyond carbohydrate. It can lower blood sugar, sometimes hours later, and your medicines matter. Read alcohol and blood sugar and ask your clinician whether alcohol is safe for you before the party.
Travel days and gift baskets
- Pack more than you think you need. Carry your medicines, meter or sensors, strips, and fast-acting carbohydrate in a bag you keep with you, not in checked luggage, and bring extra in case travel is delayed.
- Plan food for the road. Airports, rest stops, and gas stations push you toward sweet and starchy choices. Our convenience store guide and restaurant guides list real options with carbs.
- Expect odd meal times. The Diabetes Food Hub warns that holiday meals may be served at 3:00 or 4:00 p.m. Ask when food will be served, and talk to your provider beforehand if you take insulin or other glucose-lowering medicine.
- Handle gift baskets and tins. Share them at work, freeze single portions, or put a few treats in a container and keep the rest out of sight. Check labels before you assume that a “sugar-free” item is low in carbohydrate. Our guide to reading nutrition label carbs shows what to look for.
- Keep moving. Walking is the easiest tradition to add. The Diabetes Food Hub suggests after-dinner walks, touch football, or a dance party, and our walking after meals guide explains what the research shows.
If you use a CGM or meter
- Check more often when the routine changes. The Diabetes Food Hub recommends this for changes in meal timing, food types, activity, and stress, all of which describe a holiday.
- Look at the shape, not one number. A rise after a large meal is normal. The question is how high and how long. See how to read your CGM data.
- Log it. Our post-meal glucose tracker helps you compare a holiday dinner with a normal one.
- Do not chase numbers with extra medicine. Adjusting insulin or other medicine is your prescriber’s decision.
The day after
Go back to your usual routine at the next meal. Eat breakfast and lunch normally instead of skipping them to make up for the holiday, because skipping can set up low blood sugar and a bigger meal later. Drink water, take a walk if your clinician says activity is safe for you, and use leftovers wisely: lean meat and vegetables make an easy plate, and freezing single portions of pie keeps one dessert from becoming a week of dessert. If you have very high readings with symptoms such as extreme thirst or vomiting, call your clinician. One high day is information, not failure.
Common mistakes
- Saving up carbs by skipping meals. It tends to backfire.
- Treating the whole month as one big meal. December has dozens of food moments. Your plan has to work on the ordinary days too.
- Forgetting drinks. Eggnog, cocoa, cider, and mulled wine can add 25 to 30 grams or more per serving.
- Trusting a single carb count. Lists disagree, and homemade recipes differ.
- Making it all or nothing. One high reading does not undo your progress.
- Changing medicine by yourself. Talk to your prescriber first.
Questions to bring to your appointment
- What carbohydrate range is right for a holiday meal given my medicines?
- Does my medicine put me at risk for low blood sugar if a meal is late or I drink alcohol?
- How often should I check my glucose during the holidays, and when should I call you?
- What should I do if I travel across time zones or my routine changes?
- Would a CGM help me see how holiday foods affect me?
Frequently asked questions
How many carbs should I eat at Christmas dinner?
There is no single number that fits everyone. The right amount depends on your medicines, your usual carbohydrate intake, and how your own glucose responds. A practical approach is to know what your usual meal looks like, use the plate method, and pick one or two starchy favorites. Ask your care team or a dietitian for a range that fits you.
Can I eat cookies at a Christmas party if I have diabetes?
Many people with diabetes eat dessert occasionally. Published counts put two typical sugar cookies at about 22 grams of carbohydrate, but cookie size varies a lot, so a big bakery cookie can carry far more. Many people choose one or two they really want, eat them after a meal that includes protein and vegetables, and take a short walk. Your own glucose response is the real test.
Is eggnog okay with diabetes?
Eggnog is one of the highest-carbohydrate holiday drinks. Published counts list about 30 grams of carbohydrate in half a cup, so a full cup is about 60 grams. It is often treated as a dessert, not a drink. If you want it, ask your care team how it fits your plan, and consider a small serving.
Should I skip meals earlier in the day to save room for Christmas dinner?
Skipping meals is not a safe default, especially if you take insulin or a sulfonylurea, because it raises the chance of low blood sugar followed by overeating. The American Diabetes Association advises planning for holiday meals served at unusual hours, checking more often if you take glucose-lowering medicine, and bringing a snack if a meal runs late. Ask your care team before changing how you eat around your medicines.
Can I drink alcohol at Christmas parties?
Alcohol can lower blood sugar, especially with insulin or a sulfonylurea or when you drink without food, and mixers, mulled wine, and cider add carbohydrate. Ask your clinician whether alcohol is safe for you. Our guide to alcohol and blood sugar covers carbs in common drinks and the timing of lows.
What should I do the day after a big holiday meal?
Go back to your usual meals and routine. Eat normally instead of skipping meals to make up for the holiday, take a walk if your clinician says activity is safe for you, and look at your glucose pattern as information, not a grade. If you have very high readings with symptoms such as extreme thirst or vomiting, call your clinician.
Do the carb counts in this guide apply to my family’s recipes?
Only roughly. The numbers are published averages for typical servings. Homemade recipes, brands, and portion sizes change them, and some lists disagree with each other on the same food, so treat every count as an estimate and use a label, an app, or your own CGM or meter readings to learn what your versions do.
