White rice will make you fat. However if you use boiled rice you will get healthy. This is the unpolished red rice. Usually popular in the coastal belt.
It depends on your taste however. Not everyone likes boiled rice.
At night you may also take a glass of the rice water with a pinch of salt. I mean the water in which you cook the rice. It's most healthy.
It is a myth. Good combination of food and activity helps one to be slim and fit. Most obese people in the US don't eat rice and most fit people in China eat mainly rice.
