Dragon fruit, also called pitaya or pitahaya, is a vibrant tropical fruit prized for its mild sweetness and striking appearance. Because fresh produce calories vary by size, hydration, and variety, a serving estimate is often more useful than a generic whole-fruit number. This calculator converts your portion — grams, ounces, cups of diced cubes, or whole fruits — into total calories and key macros in one step.
Using average USDA values for raw dragon fruit (60 kcal per 100 g), the tool also reports protein, carbohydrates, fat, fiber, and sugar. It is handy for anyone tracking a meal plan, counting macros, or simply trying to understand how a reasonable portion fits into their daily energy needs. Enter your serving size, adjust the number of servings, and press calculate.
🐉 Dragon Fruit Nutrition Calculator
How to Use This Tool
The calculator is designed around real-life portions, not just grams. Type a number in the serving-size field and choose the matching unit from the dropdown: grams, ounces, cups of diced cubes, or whole fruit. If you want one of the most common amounts, tap a preset pill below the field to fill the values instantly — 100 g (3.5 oz), 1 cup (165 g), 1 whole fruit (330 g), or 1 oz (28 g).
Set the number of servings to 1 for a single portion, 2 when you are sharing a large bowl, or 0.5 if you only ate half of the fruit. After you press Calculate Calories, the result panel shows total energy, protein, carbohydrate, fat, fiber, and sugar for that portion.
Tip: No food scale? One loosely packed cup of diced dragon fruit is about 165 g, and a medium whole fruit supplies roughly 330 g of edible flesh. Weighing your typical portion once makes future logging much faster.
How the Calculation Works
The calculator uses average nutrient values for raw dragon fruit per 100 g of edible flesh: 60 calories, 0.9 g protein, 12.9 g total carbohydrate, 0.3 g fat, 1.9 g fiber, and 8.0 g sugars. These figures are typical of white-fleshed pitaya in major food-composition databases such as USDA FoodData Central.
First, your chosen unit is converted to grams. The factors are 1 oz = 28.35 g, 1 cup of diced cubes = 165 g, and 1 whole fruit = 330 g. Then each nutrient is scaled linearly by weight. The calorie formula is: (serving in grams ÷ 100) × 60 = total calories. The same proportional logic is applied to protein, carbs, fat, fiber, and sugar, making the tool reliable for any portion you enter.
Example: A 250 g bowl of dragon fruit contains (250 ÷ 100) × 60 = 150 kcal, about 2.3 g protein, 32.3 g carbohydrate, 0.8 g fat, 4.8 g fiber, and 20 g sugar.
Dragon Fruit Reference Values
The table below summarizes the baseline values used in the calculator. Use it when you need a fast estimate without opening the tool.
| Nutrient | Per 100 g | Per cup (165 g) | Per average medium fruit (330 g) |
|---|---|---|---|
| Calories | 60 kcal | 99 kcal | 198 kcal |
| Protein | 0.9 g | 1.5 g | 3.0 g |
| Carbohydrate | 12.9 g | 21.3 g | 42.6 g |
| Fat | 0.3 g | 0.5 g | 1.0 g |
| Fiber | 1.9 g | 3.1 g | 6.3 g |
| Sugars | 8.0 g | 13.2 g | 26.4 g |
Because a "medium fruit" is not a fixed standard, actual fruit can range from 150 g to over 450 g. Weighing the edible flesh gives the most accurate estimate.
Worked Examples
Example 1 — one whole fruit: Choosing 1 whole fruit uses a 330 g edible portion and returns about 198 kcal, 3.0 g protein, 42.6 g carbs, 1.0 g fat, 6.3 g fiber, and 26.4 g sugar. That makes a satisfying, low-calorie snack for most eating plans.
Example 2 — two cups in a fruit salad: Two cups of diced dragon fruit total 330 g, so the macros match Example 1. This shows why weight-based entries are more reliable than guessing by pieces.
Example 3 — a small 3-ounce snack: Three ounces equals 85 g and provides about 51 kcal, 0.8 g protein, 11 g carbs, 0.3 g fat, 1.6 g fiber, and 6.8 g sugar.
Factors That Affect Accuracy
Dragon fruit is a natural product, so numbers shift with variety, ripeness, and water content. Red-fleshed pitaya tends to contain more antioxidants and can taste sweeter; yellow-skinned varieties often have higher sugar than white-fleshed types. As fruit ripens, some starches convert to sugars, so an overripe fruit can be slightly higher in sugar per gram. Storing cut fruit uncovered causes moisture loss, which concentrates calories per gram.
Processed products behave differently. Dried dragon fruit strips, fruit leather, or frozen pieces packed with syrup will have much higher calories and sugar than fresh fruit because water is removed or sugar is added.
Please note: These results are educational estimates, not a laboratory analysis. If a packaged product includes a nutrition facts label, use the label values rather than this tool.
Frequently Asked Questions
Is dragon fruit good for weight loss? Yes, it is low in calories and provides fiber, but weight loss ultimately depends on your total calorie balance. For a daily energy target, try the energy calorie calculator.
How many calories are in one whole dragon fruit? Using the average 330 g edible portion, one whole fruit supplies roughly 200 kcal. Since actual fruit can weigh anywhere from 150 g to 450 g, the range is about 90–270 kcal. Weighing the flesh after removing the skin is the most dependable approach.
Does red dragon fruit have different nutrition? The macronutrient and calorie profile is similar to white-fleshed pitaya. Red varieties are often richer in antioxidants and may be slightly sweeter, but you can still use this calculator as a solid estimate for either type.
Do frozen dragon fruit cubes have different calories? Freezing without syrup or sugar preserves the original calories and macronutrients. Extra ice on the surface can change the portion weight, so weigh thawed pieces without excess liquid for the most accurate entry.
