Eggplant (aubergine) is a versatile, low-carb vegetable popular in Mediterranean, Asian, and plant-based diets. Whether you’re tracking net carbs for keto, managing blood sugar, or simply curious about its macronutrient profile, this calculator gives you the exact carbohydrate content per 100 grams — including total carbs, fiber, and net carbs.
Simply select the preparation method (raw, cooked, or grilled) and enter the weight in grams. The tool instantly breaks down total carbohydrates, dietary fiber, and net digestible carbs. It also provides a per-serving estimate based on common portion sizes. Perfect for meal preppers, diabetics, keto followers, and anyone aiming for precise carb counting.
🍆 Eggplant Carbs Calculator
How to Use This Tool
Using the Eggplant Carbs Calculator is straightforward. Enter the weight of your eggplant in grams (default is 100 g). Select the preparation method — raw, cooked (boiled/steamed), or grilled/roasted — because cooking affects water content and carbohydrate density. Click Calculate to see total carbohydrates, dietary fiber, and net carbs for that specific weight. The result also shows the per-100 g values for quick reference. Use the preset buttons (50 g, 100 g, 200 g) to quickly test common portion sizes.
How It Works
The calculator uses standard USDA nutritional data for eggplant. Raw eggplant contains approximately 5.88 g of total carbohydrates and 3.0 g of dietary fiber per 100 g, yielding about 2.88 g of net carbs. Cooking methods alter these values slightly due to water loss or absorption:
- Raw: 5.88 g total carbs, 3.0 g fiber, 2.88 g net carbs per 100 g
- Cooked (boiled/steamed): 4.5 g total carbs, 2.5 g fiber, 2.0 g net carbs per 100 g — water dilutes the carb concentration slightly.
- Grilled/Roasted: 6.0 g total carbs, 3.2 g fiber, 2.8 g net carbs per 100 g — moisture evaporates, concentrating nutrients.
The formula is simple: Total Carbs = (CarbsPer100g × Weight) / 100. Net carbs are then total carbs minus fiber. This calculation is consistent with standard nutrition labeling practices.
Worked Examples
Example 2: You grilled 200 g of eggplant. Total carbs = (6.0 × 200) / 100 = 12.0 g. Fiber = (3.2 × 200) / 100 = 6.4 g. Net carbs = 12.0 - 6.4 = 5.6 g.
Tips & Best Practices
- Weigh eggplant after trimming the stem and calyx — those parts are not typically eaten.
- For recipes that combine multiple vegetables, calculate each ingredient separately and sum the carbs.
- If you salt and drain eggplant before cooking (to reduce bitterness), some water-soluble nutrients may be lost, but carb values remain largely unchanged.
- Eggplant skin contains most of the fiber, so keep the skin on for maximum fiber intake.
Factors Affecting Accuracy
Carbohydrate content can vary slightly based on eggplant variety (e.g., Italian, Japanese, Thai), growing conditions, and ripeness. The values used here are averages from the USDA FoodData Central database. For medical or strict dietary needs, consult a registered dietitian or use lab-tested values from packaged products.
Frequently Asked Questions
Is eggplant keto-friendly? Yes, with only ~2-3 g net carbs per 100 g, eggplant is an excellent keto vegetable. It's often used as a low-carb substitute for pasta (e.g., eggplant lasagna) or pizza crust.
Does cooking increase carbs? Cooking does not create or destroy carbohydrates, but it changes water content. Grilling removes water, so the same weight of grilled eggplant has slightly more carbs per gram than raw. Boiling adds water, diluting the carb concentration.
Can I use this for other varieties like Chinese or graffiti eggplant? Yes, the carb values are very similar across common varieties. Differences are negligible for most tracking purposes.
How does eggplant compare to other low-carb vegetables? For comparison, see our bell pepper fiber calculator or broccoli calorie calculator for more vegetable nutrition data.
