Assumed: 1 katori cubes ≈ 150 g — flesh only — mostly water, which is the point.
Watermelon (Tarbooz) by portion
Everything scales linearly from the 150 g serving. If your portion is bigger, so is the number.
| Portion | Grams | Calories | Protein | Carbs | Fat | Fibre |
|---|---|---|---|---|---|---|
| 1 × 1 katori cubes | 150 g | 30 kcal | 0.9 g | 5.9 g | 0.3 g | 1.0 g |
| 2 × 1 katori cubes | 300 g | 61 kcal | 1.8 g | 11.7 g | 0.6 g | 2.1 g |
| 3 × 1 katori cubes | 450 g | 91 kcal | 2.7 g | 17.6 g | 0.9 g | 3.2 g |
| Per 100 g | 100 g | 20 kcal | 0.6 g | 3.9 g | 0.2 g | 0.7 g |
Carbohydrate is available carbohydrate; fibre is listed separately and is in neither the carbohydrate column nor the energy figure. Energy is reconciled against 4P + 4C + 9F on every build.

Read this with it: Nearly 95% water, which is the entire point of it on a fasting day. The pale green variety at E066 is lighter still. The figure carried here before overstated its energy by about half.
How watermelon (tarbooz) is counted here
- The serving is the portion this food is actually eaten in — 1 katori cubes, taken as 150 g — not an anonymous 100 g.
- Composition is read off a named row: Indian Food Composition Tables 2017 (ICMR–NIN) (food code E065, Water melon, dark green, sugar baby (Citrullus vulgaris)), and the label on that row is printed above rather than hidden.
- Carbohydrate is available carbohydrate. Where a source publishes carbohydrate by difference, the fibre is subtracted here and the subtraction is stated.
- Energy is reconciled against Atwater factors on every build; a value that disagrees with its own macros does not ship.
serving kcal = 20 kcal/100 g × (150 g ÷ 100) = 30 kcal check = 4·P + 4·C + 9·F (±15%, ±20% high-fibre)
Observances it appears in
Where watermelon (tarbooz) shows up in the food customarily associated with an observance on this site. This is a description of common practice, not a rule.
Where it sits on a fasting plate
Among the 12 entries in fruit on this site, watermelon (tarbooz) ranks 12 of 12 for energy density at 20 kcal per 100 g.
Protein supplies 12% of its energy. That is respectable for the permitted list, but a whole day built on foods like this will still run short — see protein during a vrat.
It is light enough that the portion is forgiving, which is rare on a vrat food list.
Questions
Is watermelon (tarbooz) eaten during a vrat?
It is commonly eaten during a phalahar vrat in most households. Customs differ by family, region and community — this describes what is usual, not what is required. On this site it appears in the food list for Chaitra Navratri, Nirjala Ekadashi, Vat Savitri Vrat.
How many calories are in 1 katori cubes of watermelon (tarbooz)?
About 30 kcal for 1 katori cubes, taken as 150 g (flesh only — mostly water, which is the point). That is 0.9 g protein, 5.9 g carbohydrate and 0.3 g fat. Per 100 g it carries 20 kcal.
Is watermelon (tarbooz) filling, or just energy?
Protein supplies about 12% of its energy, which is moderate. Pair it with curd, milk or nuts where your observance permits. Fibre is low at 0.7 g per 100 g. On a vrat that matters more than usual, because so much of the permitted food list is rapidly digested starch.

Practices are described as commonly observed; customs differ by family, region, community and sampradaya, and this site is not an authority on any of them. Food values come from the Indian Food Composition Tables 2017 (ICMR–NIN), the older ICMR–NIN tables, USDA FoodData Central, named composition studies and the shared ThaliFacts dataset, reconciled against Atwater factors on every build. Which source applies to which food is listed per food, and every source carries the date it was last checked. General information only — not medical or religious guidance. Fasting is not safe for everyone, particularly during pregnancy or with diabetes or other conditions. Speak to a doctor first.
