@Cezar4911 600 grams of raw white rice = 472 grams of carbs.

This is equivalent (in energy from carbs) to:

Honey 26 g
Dates, Fresh 50 g
Grapes, Raw 200 g
Passion Fruit Juice, Yellow 200 g
Papayas, Raw 200 g
Plums, Raw 400 g
Watermelon, Raw 300 g
Tamarind juice with sugar 400 g
Mango, Fresh 400 g
Orange Juice, Fresh 1000 g
Milk, Whole 1000 g

With this, you probably don't even need extra water during the day or to worry about potassium, vitamin C and half of vitamin E. It's also pretty much starch free, oxalates free and low to moderate fiber.
