When we choose to eat foods with a lower "glycemic index" (GI value), that is, "low-glycemic foods" (low GI foods), these foods can make people feel fuller and less likely to be hungry. It can avoid eating too much food; on the contrary, foods with a higher "glycemic index" (GI value), that is, "high glycemic foods" (high GI foods), will make people full and hungry faster. As a result, the more you eat, the hungrier you become, which is not conducive to dietary management.
