As far as rice and flour with the same weight are concerned, the total calories they produce in the human body are the same, and the difference in nutritional components is not great, that is to say, there is no fattening factor in flour than rice. However, the water absorbed by rice is greater than that required by cooked food such as steamed bread and dried noodles. Therefore, at the same weight, eating pasta consumes more energy than eating rice. However, as long as the total calories of eating do not exceed the body's needs, neither eating rice nor pasta will make the body fat.
