November 5, 2025 •

4 min read

The calorie count for a single old fashioned doughnut can range significantly depending on the brand and size, with some larger varieties containing well over 400 calories. This variability is a crucial factor when considering how many calories are in one old fashioned doughnut as part of a balanced diet.

Quick Summary

The calorie count for a single old fashioned doughnut varies by brand and size, typically ranging from 300 to over 400 calories. The treat is high in fat, sugar, and refined carbohydrates, with minimal protein or fiber, offering very limited nutritional benefits.

Key Points

Variable Calorie Count: The number of calories in an old fashioned doughnut can differ significantly, typically ranging from 300 to over 400 kcal depending on brand and size.
High in Fat and Carbs: This doughnut is primarily composed of refined carbohydrates and fat, with one average portion containing around 18-19g of fat and 30-33g of carbohydrates.
Minimal Nutritional Value: Beyond energy, the doughnut offers little in the way of essential nutrients like fiber, vitamins, or minerals.
High in Sugar: The sweet treat contains a considerable amount of sugar, contributing to its high-calorie density and potential impact on blood sugar levels.
Moderation is Key: Due to its high calorie and low nutritional content, an old fashioned doughnut is best enjoyed as an occasional treat rather than a regular part of your diet.
Consider Healthier Alternatives: For sweet cravings, opt for nutrient-dense options like fruits, homemade baked goods, or protein balls to support healthier eating habits.

The Calorie and Macronutrient Profile

Determining the exact calorie count for an old fashioned doughnut is complex, as it varies widely based on brand, recipe, and size. Generic estimates from nutrition databases and specific brand information reveal a broad range. For example, a generic estimate places the calorie count around 308-310 calories for a standard-sized plain old fashioned donut, derived mostly from fat and carbohydrates. On the other hand, a glazed version from a supplier might reach 320 calories. High-end coffee shops, like Starbucks, offer more indulgent versions, with one old-fashioned doughnut clocking in at 480 calories.

Breaking Down the Macronutrients

Beyond just the total energy, understanding the macronutrient composition is key to grasping the nutritional impact of a doughnut. A typical plain old-fashioned doughnut is overwhelmingly composed of refined carbohydrates and fat. According to Nutritionix, a standard old-fashioned doughnut provides approximately 18g of total fat and 33g of carbohydrates, with 13g of sugar. There is also a small amount of protein, typically less than 4g per serving. The saturated fat content is also high, often accounting for a significant percentage of the total fat. These high levels of sugar and fat contribute to the significant calorie load without providing much in the way of essential vitamins, minerals, or dietary fiber.

Comparison of Doughnut Varieties

To put the calories of an old fashioned doughnut into perspective, it's helpful to compare it with other popular types. The table below illustrates the nutritional differences, showing how a simple change in preparation or topping can drastically alter the final calorie count.


Doughnut Type (Single Serving)	Typical Calories	Total Fat (g)	Total Carbs (g)	Total Sugars (g)
Plain Old Fashioned	~308-310	18-19	30-33	10-13
Dunkin' Glazed	~240	-	-	-
Krispy Kreme Original Glazed	~190	11	22	10
Krispy Kreme Traditional Cake	~290	18	28	10
Starbucks Old Fashioned Glazed	~480	-	-	-

Health Implications of High-Calorie Treats

While delicious, indulging in an old-fashioned doughnut is a high-calorie, low-nutrient affair. The high fat and sugar content, especially when consumed regularly, can contribute to several health concerns. These include:

Weight Gain: The high calorie density means a single doughnut can represent a significant portion of a person's daily calorie intake, making it easy to consume excess calories without feeling full.
Blood Sugar Spikes: The combination of simple sugars and refined carbohydrates can cause a rapid increase in blood sugar, followed by a crash, which can impact energy levels and mood. This is particularly concerning for individuals managing diabetes.
Increased Chronic Disease Risk: Diets high in saturated and trans fats, sugars, and processed carbs are linked to an increased risk of heart disease, type 2 diabetes, and other chronic illnesses over time.
Minimal Satiety: Because of the low fiber and protein content, a doughnut provides little lasting satisfaction, often leading to cravings for more sugary snacks shortly after consumption.

Making a Healthier Choice

Mindful consumption is key to enjoying treats like old-fashioned doughnuts without derailing your diet. If you choose to have one, consider it an occasional indulgence rather than a regular snack. For those looking for a healthier alternative to satisfy a sweet craving, there are many delicious options.

Here are some healthier treat ideas:

Baked Goods: Look for recipes that use whole wheat flour, reduce sugar, and substitute unhealthy fats with alternatives like applesauce or Greek yogurt. Making your own at home provides complete control over ingredients and portion size.
Fruit-Based Desserts: Enjoy a bowl of fresh berries, a baked apple with cinnamon, or a homemade fruit smoothie. These options are rich in fiber and vitamins.
Yogurt Parfait: Layer Greek yogurt with fresh fruit and a small sprinkle of nuts or low-sugar granola for a protein-packed, satisfying treat.
Dark Chocolate: A small square of high-quality dark chocolate can satisfy a sweet craving and provides antioxidants.
Homemade Protein Balls: Blend oats, nut butter, protein powder, and a touch of honey for a quick, filling, and customizable snack.

Conclusion

While a single old-fashioned doughnut is a tempting and nostalgic treat, it is undeniably a high-calorie food with a poor nutritional profile. The calories typically fall in the 300-400 range for many standard varieties, but can climb much higher with specific brands or additional toppings. To maintain a balanced diet and support overall health, it is best to enjoy such foods in moderation. By understanding the calorie and macronutrient breakdown, you can make more informed choices and explore healthier, nutrient-dense alternatives for your sweet cravings.
