A cup of blueberries is about 84 calories — from USDA’s 57 calories per 100 g across a 148 g serving. That’s a low-calorie, nutrient-dense way to add sweetness to a meal: a full cup of berries, famous for antioxidants, for less than the calories in a single slice of bread. Like most berries, blueberries are mostly water and fiber, so a cup feels like a real portion while staying light.
Where blueberries’ calories come from
Blueberries are a carbohydrate fruit, and the breakdown is clear: about 91% of the calories come from carbohydrate — natural sugar plus fiber — with only a few percent each from trace protein and fat. The famous part of a blueberry, its anthocyanins (the deep-blue antioxidant pigments tied to brain and heart health), and its vitamin C and vitamin K, contribute no calories at all. So an 84-calorie cup is essentially carbohydrate, but carbohydrate that arrives with roughly 4 g of fiber and a standout antioxidant load — a genuinely good trade for the calories.
Low-density and easy to enjoy
On calorie density, blueberries sit comfortably on the light end of the fruit aisle — a little denser than watery strawberries, well below a banana — so a generous cup is still only ~84 calories and a whole pint stays under ~170. That makes them one of the easier fruits to enjoy by the handful without watching the count closely. The practical role they play best is as a flavor-and-nutrient add-on: a cup stirred into Greek yogurt, oatmeal, or a protein shake adds sweetness, fiber, and antioxidants for a small calorie cost, while the dairy or powder does the heavy lifting on protein. When a food is this nutrient-dense for the calories, the honest advice is to use it freely.
For the macro flip side, see protein in blueberries — they’re an antioxidant carb, and their calories are some of the better-spent ones in the produce section.
Frequently Asked Questions
How many calories are in a cup of blueberries?
About 84 calories in a 1-cup serving (148 g), based on USDA's 57 calories per 100 g (FDC 171711). That cup also brings roughly 4 g of fiber and a big dose of antioxidants, so the calories come with real nutritional value.
How many calories are in blueberries per 100 g or per ounce?
57 calories per 100 g, which is about 16 calories per ounce (28 g). That's a low calorie density — a touch higher than strawberries, lower than a banana — so a generous cup still lands under 90 calories.
Where do the calories in blueberries come from?
Almost all carbohydrate. Using standard Atwater factors, about 91% of a blueberry's calories come from carbs (natural sugar and fiber), with only a few percent each from trace protein and fat. They're an antioxidant-rich carbohydrate fruit.
Are blueberries good for weight loss?
They fit well. A cup is only about 84 calories with ~4 g of fiber, so blueberries are nutrient-dense and low in calorie density — a satisfying way to add natural sweetness and antioxidants to oats, yogurt, or a shake without much energy cost. Portion is easy to keep sensible since a cup is already filling.
How many calories are in a pint of blueberries?
A pint is roughly two cups (about 300 g), so close to 170 calories. Even eating a whole pint keeps you under 200 calories while delivering a large dose of fiber and antioxidants — which is why blueberries are an easy fruit to enjoy by the handful.
