The calorie of a bowl of rice (360g) is approximately equal to that of 18 piece of fruit candy.
First of all, you can't just eat white rice for every meal. You have to eat with the food. Even boiled vegetarian dishes have calories. So you should consume at least 400 calories per meal.
If you eat fruit candy instead, a piece of fruit candy is 20 calories, so it is unlikely that you will eat 20 pieces of candy at one breath. I don't want to eat any more if I eat four pieces at most. Converted down, even the heat of half a bowl of rice is less than.
If you don't finish half a bowl of rice at a meal, you will definitely lose weight! That's what I did. I lost 50 pounds in three months.
But there is one thing. You said you wouldn't eat, but you really wouldn't eat at all, not even a grain of rice.
