What happens if you don't eat for three days?

If a person does not eat for three days, it will cause some damage to the body. For example, blood sugar will drop to the lowest point, and it will be like stepping on cotton. Walking is unsteady. Therefore, the body can only turn to mobilizing fat to generate heat and maintain life. Subcutaneous fat and visceral fat can store energy. Within a day of fasting, the body can also consume glycogen reserves. Later, it will start to consume fat and even muscle protein. Hungry for 3 days without eating, first of all will feel dizzy, vomiting nausea, listlessness, weakness, etc., poor physical strength will even faint unconscious, and even shock. Therefore, even if diet is harmful to the body, such as malnutrition, let alone fasting for 3 days. Do not eat for a few days, the body immunity continues to decline.
