I tried to lose weight without eating staple food for a while myself. But I feel very hungry. For example, you can skip rice and noodles in the morning. But you will also eat some biscuits and so on. Although these words are not staple food, they also contain some essential ingredients in your body, such as carbohydrates, vitamins, protein and so on. But if you only eat biscuits, you will easily feel hungry. Because it contains far less nutrients than bread or cake, it needs more energy.
Then talk about noon. At noon, your staple food can be noodles or rice, and these, if you only eat vegetables and fruits. Or yogurt and milk. Your health, although I won't feel hungry at that time, because these fruits and vegetables often make you feel full. But if you can't wait for dinner at night, your stomach will growl. Because you don't consume the energy of staple food, your body consumes far more energy than you do at this time. In this case, you will definitely consume your body fat or protein.
Because of your poor diet management. Because staple food will bring necessary nutrition to your body. Although you lost weight successfully, you didn't consume so much fat, and your body's protein was also consumed.
So it is ok to lose weight without eating staple food. Well, you lost weight successfully, but you didn't lose weight healthily and reasonably. If you persist for a long time, it will be bad for your health. Although you may have reached your target weight, your weight will easily rebound and your body will be overwhelmed. So I suggest that if you want to lose weight, you should eat the staple food in moderation.
