The reasons for wanting to eat sugar during weight loss are as follows: 1. The body needs energy: during weight loss, we usually reduce the intake of calories, and the body needs to replenish energy. Sugar food can provide energy quickly. 2. Hypoglycemia: During weight loss, if we excessively reduce the intake of sugar, the blood sugar level may be too low. At this time, we will feel tired and hungry, and want to eat sugar to improve blood sugar level. 3. Emotional stress: Losing weight is a challenge for some people, and emotional stress may lead to the desire to eat sugar to relieve stress and discomfort. 4. Habits: Long-term eating habits and love for sugary foods may lead to a desire to eat sugar during weight loss.
