Raw bottle gourd has about 3.4 grams of carbohydrates per 100 grams, with roughly 2.9 grams of net carbs after fiber.
Bottle gourd (also called lauki or calabash) is a watery, mild squash that fits easily into low-carb plates. If your question is about carbohydrates in bottle gourd across real portions and cooking styles, this article gives clear numbers, useful context, and practical swaps, backed by standard nutrient datasets.
Carbohydrates In Bottle Gourd: Net Carbs By Serving
To keep choices simple, start with raw values from lab-based data. Per 100 grams, bottle gourd provides about 3.39 g carbohydrate and ~0.5 g fiber, so net carbs land near 2.9 g. These figures track closely with the USDA-derived tables used by widely cited nutrition databases. For a fast check on the baseline, see the MyFoodData entry for calabash.
| Portion | Total Carbs (g) | Net Carbs (g) |
|---|---|---|
| 50 g (about 4–5 tbsp diced) | ~1.7 | ~1.45 |
| ½ cup, 1″ pieces (~58 g) | ~2.0 | ~1.7 |
| 1 cup, 1″ pieces (~116 g) | ~4.0 | ~3.4 |
| 100 g (weighed raw) | ~3.4 | ~2.9 |
| 150 g (small bowl) | ~5.1 | ~4.3 |
| 1 medium gourd slice (~180 g) | ~6.1 | ~5.2 |
| 1 whole small gourd (~800 g edible) | ~27.1 | ~23.1 |
Method note: Net carbs = total carbohydrate − fiber. Fiber varies slightly with maturity and seed content. The figures above use ~0.5 g fiber per 100 g for raw flesh. For a serving cross-check (½ cup cubes ≈ 1.97 g carbohydrate), see the USDA carbohydrate table (PDF).
Why Bottle Gourd Stays Low In Carbs
This vegetable is ~95–96% water by weight, which dilutes starch and sugar. The small carb load per bite makes bottle gourd a friendly filler for soups, dal, sabzi, and mixed stir-fries. The flavor is neutral, so it carries spices well without adding much to your carb budget.
Close Variant: Bottle Gourd Carbohydrates For Low-Carb And Diabetes Plans
Two factors matter most for blood sugar: the net carb load of the portion and how fast those carbs digest. The net load for typical home servings is modest, as the first table shows. Speed of digestion is low to moderate due to high water and fiber. Direct lab GI numbers for bottle gourd are limited, yet compilers that draw from USDA data classify both raw and boiled calabash as low-glycemic foods. In daily cooking, the entire dish still depends on what you pair with it—oil, potatoes, lentils, and grains shift totals far more than the gourd.
Glycemic Index And Load In Daily Meals
Glycemic index (GI) describes speed; glycemic load (GL) describes impact for the portion you eat. GL is simple math: GL = GI × grams of carbs in the portion ÷ 100. Because portions of bottle gourd usually carry only 2–5 g available carbs, GL tends to be very low even when the GI estimate sits in the lower range. That’s one reason many home cooks lean on lauki to stretch curries without pushing carb counts.
To see how the math plays out with carbohydrates in bottle gourd, think about a cup of raw cubes with ~3.4 g net carbs. If a low GI value applied, the GL would still be well under 5, which is considered a small effect per portion. Add high-GI sides and the GL of the meal rises; keep sides light and your plate stays gentle.
Portion Math You Can Trust
Weigh Raw For Consistent Tracking
Weighing raw diced pieces gives the cleanest results because the baseline is stable. If you track by cups, expect small swings as piece size changes. A loosely filled cup holds more air than tightly packed cubes.
Scale Recipes Without Re-Calculating
Multiply the raw grams in your recipe, then apply the 3.39% carbohydrate rate. For example, 400 g raw bottle gourd carries ~13.6 g carbohydrate. Split that across four servings and you’re near 3.4 g per serving before add-ins.
If you batch-cook, log the total raw weight of gourd added to the pot and divide by the number of portions you plate; this keeps a week’s worth of meals aligned with the same baseline.
Watch The Add-Ins
Gourd on its own is mild and low carb. Onions, tomatoes, potatoes, and legumes raise the final count. Spices and herbs add flavor with almost no carbohydrate.
Buying, Storing, And Prepping For Best Numbers
Pick Fresh, Young Fruit
Choose light-green, firm gourds with soft seeds. Over-mature fruit can taste bitter and may carry slightly more fiber and less water. If bitterness is present, discard the batch.
Store Cold And Use Soon
Keep uncut gourds in the fridge crisper for 3–5 days. Once cut, wrap and use within two days to keep texture and moisture.
Prep Steps That Keep Carbs Predictable
Peel thinly, remove seeds if hard, and dice evenly. Salting and rinsing is optional for firmer texture. Blanching for a minute helps set color before stir-fries.
Compare With Similar Vegetables
People often log ash gourd (winter melon) or zucchini by mistake. These are different plants with their own profiles. Ash gourd usually sits in the same low-carb zone per 100 g, while zucchini trends a touch higher due to slightly less water. If you want strict accuracy, weigh the exact vegetable and use its specific entry in your tracker.
How To Log Bottle Gourd In Apps
Pick The Exact Entry Name
Search for “calabash” or “gourd, white-flowered” for the closest match. Many apps mirror USDA field names. If you only see cooked entries, switch the database filter to raw and re-try.
Check The Serving Denominator
Some entries default to “1 cup.” If your scale reads grams, switch the unit to grams before typing. This keeps the carb math aligned with the 100 g reference.
Save Your Home Recipe
For a family sabzi that repeats each week, build a recipe once with raw weights for each ingredient. The app will scale servings for you next time.
Smart Swaps To Keep Carbs Low
- Swap potatoes with extra bottle gourd in stews to shave 8–10 g carbs per 100 g of the mix.
- Use grated gourd in kofta mix to cut breadcrumbs and lower carbs per patty.
- Blend boiled gourd into soup to add body without flour or cornstarch.
Carbohydrates Change With Cooking
Cooking shifts numbers by changing water content. Boiled, drained bottle gourd typically shows a slight rise in carbs per 100 g because water leaves the tissue, concentrating the solids. The total carbs you eat in a bowl can stay similar if the raw weight going into the pot is the same. Use the cooked values below to match what’s on your plate.
| State | Total Carbs (g) | Net Carbs (g) |
|---|---|---|
| Raw, diced | ~3.4 | ~2.9 |
| Boiled, drained | ~3.7 | ~3.2 |
| Stir-fried, lightly salted | ~3.7–4.0 | ~3.2–3.5 |
| Mashed with yogurt (per 100 g mix) | ~3.6 | ~3.0 |
| With lentils (per 100 g mix) | ~10–12 | ~8–10 |
| With potatoes (per 100 g mix) | ~11–14 | ~9–12 |
Data note: Raw and boiled figures reflect USDA-derived datasets. Mixed dishes are estimates to show direction, not lab values. Your pan, cut size, and drain time change the final number.
Regional Names And Labeling
You may see bottle gourd sold as lauki, doodhi, calabash, long melon, or white-flowered gourd. The scientific name is Lagenaria siceraria. Pack labels vary by region, so check the common name before logging.
Safety And Taste Notes
Very bitter gourds are not suitable for cooking. Bitterness can signal natural compounds at unusually high levels. Discard any batch that tastes bitter after a small test bite, and do not try to mask the taste with sugar or salt.
When Bottle Gourd Makes Sense For Your Goals
Weight management: Low energy density and low net carbs let you serve larger portions for few calories. Pair with lean protein to keep meals filling.
Keto or very low carb: Small side portions fit most daily limits. Measure cooked add-ins, since onions, tomatoes, and peas move the dial more than the gourd itself.
Hydration in hot weather: The high water content helps meals feel light. Salt to taste after cooking and use spices, lemon, or yogurt for brightness without adding sugar.
Digestive comfort: Soft, peeled, well-cooked cubes are easy to eat. If fiber bothers you, scoop out hard seeds and keep pieces small. For extra fiber, mix with leafy greens rather than doubling onions.

Practical Takeaway
If you want a gentle-carb vegetable to bulk up plates, bottle gourd is an easy pick. Raw flesh sits near 3.4 g carbohydrate per 100 g, fiber trims that to ~2.9 g net carbs, and boiling keeps the numbers in the same low range. Dishes stay friendly as long as the add-ins stay modest. For consistent logging, weigh raw dice, use grams, and keep the same cut size across batches. That’s all you need to keep carbs predictable.
