Halloween is a fun time of year filled with spooky costumes, pumpkins, and of course, sweet treats! But if you’re living with diabetes, all that sugar and snacking can make carb counting a challenge.
Whether you have type 1 diabetes and need to match insulin to carbs, or type 2 diabetes and are keeping an eye on portion sizes and blood glucose, a little planning can go a long way.
This blog will help you navigate Halloween carb counting with confidence. It will highlight the carbs in popular treats, offer smart swaps, and give you tips to enjoy the day.
Why Halloween carb counting can be tricky
Halloween is packed with small, tempting portions of sweets, chocolate, and baked goods. The problem is that “fun-size” doesn’t always mean “low carb”. Those little treats can add up fast, especially when there’s a bowl sitting on the counter, or you’re dipping into the leftovers after the trick-or-treaters have gone!
It’s not about avoiding everything; it’s about awareness. Understanding how many carbs are in the foods you eat helps you make informed choices, whether that means adjusting insulin, spacing out treats, or swapping higher-carb foods for lower-carb options.

Common Halloween treats and their carbs
Just a few small items can easily reach 30–50g of carbs, roughly equivalent to 2-3 slices of bread.

Tips for smarter Halloween snacking
Here are some practical ways to keep Halloween treats enjoyable and balanced:
1. Plan Ahead
If you know you’ll have a few sweets later, consider how they’ll fit into your meals that day. For example, you might swap out a high-carb snack earlier in the afternoon to leave some room for an evening treat. You could also incorporate lower-carb snacks, such as a handful of unsalted mixed nuts.
2. Weigh and Compare
Using the Carbs & Cals app makes this super easy, just search for your favourite sweets or scan the barcode to see their carb content and compare portion sizes. If the barcode is not found, try out our new AI food label scanner to quickly capture the nutrition info and save it as a custom food for next time.
3. Keep Portions Mini
Instead of eating several fun-size bars, try one or two and savour them. It can help to tip a few treats into a small bowl rather than eating straight from the bag.
4. Remember to take insulin/bolus for snacks
If you take quick-acting insulin, remember that you may need to take an extra injection/bolus (if on a pump) for snacks. Knowing the carb content and keeping track of what you are eating will help with accuracy and reduce the likelihood of blood glucose spikes.
5. Stay Hydrated
It’s easy to mistake thirst for hunger, especially with lots of snacking around. Keep a water bottle nearby to avoid unnecessary munching.

The Carbs & Cals app makes Halloween carb counting simple.
Type 1 Diabetes: Carb counting confidence
For those with type 1 diabetes, Halloween carb counting is key to matching insulin to food intake. Halloween can be unpredictable, with lots of grazing and unplanned snacking. Here’s how to keep things steady:
- Use the app for quick checks: The Carbs & Cals app has photos showing portion sizes for hundreds of sweets and snacks, so you can estimate carbs on the go.
- Log custom foods: If you’re having something homemade like Halloween cupcakes, add them as custom foods in the app so you know the carbs for next time.
- Watch out for hidden carbs: Halloween drinks like hot chocolate, pumpkin spice lattes, or fizzy drinks can add a lot of extra sugar. A medium pumpkin spice latte can contain over 40g of carbs, the same as 8 jelly babies!
- Keeping notes in your app or diabetes log can help you see patterns and act as a reminder to take insulin for snacks.

Type 2 Diabetes: Portion awareness
For those with type 2 diabetes, it’s often more about portion awareness than carb counting. Overeating carbs can lead to higher blood glucose levels, especially when treats are eaten on top of normal meals.
Here are a few type 2-friendly approaches for Halloween carb counting :
- Mindful choices: Decide in advance which treat you’ll really enjoy and skip the rest. One or two sweets can be part of your plan without overdoing it.
- Homemade options: Try making your own treats with less sugar. Roasted pumpkin seeds with a little seasoning, or dark chocolate-dipped strawberries, are great alternatives.
- Watch the drinks: Sugary drinks can easily double your carb intake for the evening. Choose diet versions, flavoured sparkling water, or herbal teas instead.
- After-dinner treats: If you want something sweet, have it after a balanced meal that includes protein, healthy fats, and fibre. This helps slow down how fast carbs are absorbed.

Healthy Halloween swaps
If you’re hosting a party or handing out treats, here are a few ideas that are still fun but a bit lighter on carbs:
- Mini bags of popcorn (salted) instead of sweets
- Mini cheese portions or savoury crackers
- Mandarin oranges with funny “pumpkin faces” drawn on the peel
- Dark chocolate squares (lower sugar than milk chocolate)
- Fruit skewers with grapes, strawberries and melon balls
- Roasted chickpeas or pumpkin seeds for a savoury crunch
These are also great options for anyone with type 2 diabetes who wants to join in the fun without too much added sugar.

Enjoy Halloween mindfully
Halloween only comes once a year, and food is part of the fun. The key is to enjoy it mindfully, stay aware of portions, and have a plan for how those extra carbs fit into your day.
Whether that means logging your sweets in the Carbs & Cals app, estimating using food photos, or simply being aware of what’s on your plate, small steps make a big difference.
You can make Halloween a treat by focusing on awareness, balance, and moderation. Not a trick for your blood glucose.
