This is not necessarily true, because whether you are fat or thin depends not only on what you eat at night, but also on the amount of exercise you do every day, what you eat during the day and how much you eat. Of course, if you don't overeat during the day and eat a little miscellaneous grains at night (be careful not to eat too much, it will make you fat), you can lose weight and keep fit. Yipin houfu
