You'd better not. I believe you can't eat any more. The nutritional elements that people need every day need to eat a variety of foods. Eating only steamed bread and rice will definitely lead to malnutrition. Do you think that there are many congenital factors in oil secretion, that is, hereditary oily skin, which is difficult to change? The acquired factor is more body fat, less greasy, but still eat oil. Can only eat vegetable oil, eat less. Eat more vegetables and coarse grains.
