Eggplant is a low-calorie, nutrient-dense vegetable that fits easily into weight-management and balanced-eating plans. This calculator converts your eggplant portion — whether measured in grams, ounces, cups, or whole fruits — into precise calorie counts, plus a breakdown of carbohydrates, protein, and fat. It's ideal for anyone tracking daily intake, meal prepping, or simply curious about the energy in their favorite ratatouille or grilled side dish.
Simply enter your portion size, choose the unit, and optionally adjust for cooking method (raw vs. cooked) to get a more accurate estimate. The tool also shows calories per gram and per 100 grams, so you can compare eggplant to other vegetables or scale recipes with confidence. Whether you're a dietitian, a fitness enthusiast, or a home cook, this calculator gives you the numbers you need in seconds.
🥘 Eggplant Calorie Calculator
How to Use This Tool
Using the eggplant calorie calculator is straightforward. Start by entering the amount of eggplant you plan to eat. You can specify the quantity in grams, ounces, cups of chopped eggplant, or as a whole medium fruit. If you're following a recipe that lists ingredients in cups or ounces, the calculator handles the conversion automatically using standard food database values.
Next, choose whether your eggplant is raw or cooked. Cooking changes the water content and can slightly concentrate calories, so this option improves accuracy. After clicking Calculate Calories, you'll see the total calories, the equivalent weight in grams, calories per gram, and a macronutrient breakdown (carbs, protein, fat). The reset button clears all fields and results so you can start a new calculation.
For quick reference, the Quick Fill buttons let you instantly test common portions like 100 grams, one cup, one medium eggplant, or 3.5 ounces. This is handy when you're estimating a serving without a scale.
How It Works
The calorie estimate is based on the USDA FoodData Central nutritional database. Raw eggplant contains approximately 25 calories per 100 grams, with about 5.9 g of carbohydrates, 1.0 g of protein, and 0.2 g of fat. When cooked (boiled and drained), the values shift slightly to about 35 calories per 100 grams, with 8.7 g of carbs, 0.8 g of protein, and 0.2 g of fat. The calculator multiplies your portion weight by these per-100g values to derive the totals.
For unit conversions, the tool uses standard approximations: 1 cup of chopped raw eggplant weighs about 82 grams, and one medium eggplant (about 5.5 inches long) weighs roughly 458 grams. These figures come from common culinary references and the USDA's portion size estimates.
Because eggplant is mostly water (about 92%), its calorie density is very low. This makes it an excellent food for adding volume to meals without adding many calories — a key principle in volume eating and weight management.
Worked Examples
Example 1: Raw eggplant in grams
You eat 150 g of raw eggplant. Calories = 150 × 25 / 100 = 37.5 kcal. Carbs = 150 × 5.88 / 100 = 8.8 g, protein = 1.5 g, fat = 0.3 g.
Example 2: One cup of chopped raw eggplant
One cup ≈ 82 g. Calories = 82 × 25 / 100 = 20.5 kcal. That's a very light addition to a salad or stir-fry.
Example 3: Half a medium eggplant, cooked
A medium eggplant weighs ~458 g, so half is ~229 g. Cooked value: 229 × 35 / 100 = 80.2 kcal. This shows how cooking can slightly increase calorie density per gram due to water loss.
Tips & Best Practices
- Weigh for accuracy: If you have a kitchen scale, weighing in grams is the most precise method. Volume measurements like cups can vary depending on how finely you chop the eggplant.
- Account for cooking oil: This calculator only estimates the eggplant itself. If you sauté or roast with oil, add those calories separately — oil adds about 120 kcal per tablespoon.
- Use for meal prep: Calculate the calories for a large batch of eggplant-based dishes (like ratatouille or baba ganoush) and divide by the number of servings to get per-serving calories.
- Compare with other vegetables: Eggplant is lower in calories than starchy vegetables like potatoes or corn. Use the per-100g value to compare with other produce in your diet.
Factors Affecting Accuracy
The values provided are averages from the USDA database. Actual calorie content can vary based on the specific variety of eggplant (e.g., Italian, Japanese, or graffiti), growing conditions, and how it's prepared. For example, frying eggplant dramatically increases its calorie content because it absorbs oil, while grilling or steaming adds negligible calories.
Also, the weight of a "medium" eggplant can range from 300 to 600 grams depending on the source. If you're tracking closely, always weigh your actual portion rather than relying on average sizes. The calculator's whole-fruit option is a convenient estimate, but not a substitute for a scale.
Frequently Asked Questions
Is eggplant good for weight loss? Yes. With only 25 calories per 100 grams raw, eggplant is one of the lowest-calorie vegetables. Its high water and fiber content help you feel full, making it a great addition to a calorie-controlled diet.
Does cooking change the calories significantly? Cooking itself doesn't add calories, but it removes water, so the same weight of cooked eggplant has more calories per gram than raw. However, the total calories in your portion remain the same if you weigh it before cooking. This calculator lets you choose the state to match how you measure.
Can I eat eggplant on a low-carb diet? Yes, in moderation. A 100g serving of raw eggplant has about 5.9 g of carbs, of which about 2.5 g are fiber, leaving roughly 3.4 g of net carbs. That's quite low compared to many other vegetables.
Where can I find more detailed nutrition data? The USDA FoodData Central is the authoritative source for food composition data. You can search for "eggplant, raw" or "eggplant, cooked" to see the full nutrient profile, including vitamins and minerals.
