Dragon fruit (pitaya) is a vibrant tropical fruit prized for its mild sweetness, striking pink skin, and creamy white or red flesh dotted with tiny black seeds. If you're tracking calories, macros, or planning a balanced diet, knowing exactly how many calories are in a 100-gram serving is essential. This calculator lets you convert any weight of dragon fruit into calories, and it also breaks down the macronutrients — protein, carbs, and fat — so you can log your intake with confidence.
Whether you're meal prepping, following a calorie deficit, or just curious about this superfood, the tool supports both metric and imperial units. You can choose between white-fleshed and red-fleshed varieties, which differ slightly in sugar and antioxidant content. The result panel shows calories per 100g, total calories for your portion, and a full macro breakdown. Use the quick-fill buttons to instantly test common serving sizes like 100g, one cup, or one whole fruit.
🐉 Dragon Fruit Calorie & Macro Calculator
How to Use This Tool
Enter the weight of your dragon fruit portion in the input field, select the unit (grams, ounces, or pounds), and choose the flesh type — white or red. The calculator instantly converts your weight to grams and applies the appropriate nutritional values per 100g. You can also use the quick-fill buttons to load common serving sizes: 100g, one cup (about 170g), or one whole fruit (about 200g). After clicking Calculate, you'll see the calories per 100g, the total calories for your portion, and a breakdown of protein, carbohydrates, and fat.
This tool is ideal for anyone tracking daily calorie intake, following a macro-based diet, or simply curious about the nutritional profile of dragon fruit. It's also handy for meal prep — you can quickly scale up or down to match your recipe.
Nutritional Values Used
The calculator uses average values from the USDA FoodData Central database. For white-fleshed dragon fruit, the typical values per 100g are approximately:
- Calories: 57 kcal
- Protein: 1.2 g
- Carbohydrates: 13.0 g
- Fat: 0.4 g
Red-fleshed varieties tend to be slightly sweeter and may contain a bit more sugar, so we use 60 kcal and 14.0 g of carbs per 100g. These figures are averages; actual values can vary by ripeness and growing conditions.
How the Calculation Works
The calculator first converts your input weight to grams using these conversions:
- 1 ounce = 28.3495 grams
- 1 pound = 453.592 grams
Then it multiplies the per-100g values by your weight in grams and divides by 100. For example, if you eat 150g of white dragon fruit:
Example: 150g × 57 kcal / 100 = 85.5 kcal. Protein: 150 × 1.2 / 100 = 1.8 g. Carbs: 150 × 13.0 / 100 = 19.5 g. Fat: 150 × 0.4 / 100 = 0.6 g.
Why Dragon Fruit Is a Great Choice
Dragon fruit is low in calories but rich in fiber, vitamin C, and antioxidants like betalains (in red varieties). A 100g serving provides about 3g of fiber, which supports digestion and helps you feel full. Its high water content (around 87%) makes it a hydrating snack, especially in warm weather. Because it's naturally sweet, it can satisfy a sugar craving without the calorie load of processed desserts.
For those managing blood sugar, dragon fruit has a moderate glycemic index (around 48-52), making it a better option than many tropical fruits. However, portion control is still important if you're watching carbohydrate intake.
Common Questions
Is dragon fruit good for weight loss?
Yes, due to its low calorie density and fiber content, dragon fruit can be a satisfying addition to a weight-loss diet. A whole fruit (about 200g) contains only about 114-120 calories, making it a smart snack.
Does the color of the flesh matter nutritionally?
Red-fleshed dragon fruit contains more antioxidants, particularly betalains, which give it its deep color. It also tends to be slightly higher in sugar, which is why we adjust the calorie and carb values.
Can I use this calculator for frozen or dried dragon fruit?
This calculator is designed for fresh fruit. Dried dragon fruit is much more calorie-dense because water is removed, so the values would be significantly higher. Frozen fruit is similar to fresh, but check the package for added sugar.
Tips for Accurate Tracking
- Weigh your fruit with a kitchen scale for the most accurate results — visual estimates can be off by 20-30%.
- If you're eating the skin (unlikely), remove it first; the skin is not typically consumed.
- Remember that the seeds are edible and contribute to the fiber content.
- When logging in an app, use the "dragon fruit" entry and adjust the serving size to match your weight.
