Why do I always feel insecure when I am not full?

This is so normal. This is the instinct of human survival. When we are hungry, our bodies are in a state of insufficient energy. Physical function will remind us to replenish energy in time to ensure the normal work of the body. Only by eating and drinking enough can the body be satisfied, the organs can work normally, the mental state will be good and the mood will be happy. People are iron rice steel, and they are hungry without eating a meal. Therefore, normal diet, normal exercise and healthy diet are the capital for us to survive better, and we can't go on a diet to lose weight.
