It is not recommended not to eat staple food, because only eating staple food rich in carbohydrates will make you feel full, and it will not reduce your basal metabolic rate, and your body will really break down fat.
Therefore, staple food must be eaten during weight loss. But try to eat less refined rice flour, because the absorption rate of refined rice flour is better, and eat more corn, corn flour, brown rice and whole wheat. It is rich in dietary fiber, and it is best to match the thickness to improve the taste. Try to make porridge, which can increase satiety.
You can also completely replace the staple food with potatoes or sweet potatoes. If you check the food calorimeter, you will find that the calories of potatoes are much lower than those of cereals under the same weight.
But if you eat fried potato chips or shredded potatoes, you must reduce the amount of staple food, or you will get fat.
These principles apply not only to dinner, but also to three meals. I am a nutritionist, I wish you success in losing weight!
