While short term fasting can be safe, it does come with potential risks, especially in children. These include: 1. Hypoglycemia: Children have a higher risk of low blood sugar levels due to lower glycogen stores. 2. Dehydration: Inadequate fluid intake can lead to dehydration, particularly in younger children. 3. Nutrient Deficiency: Prolonged fasting can lead to deficiencies in essential nutrients, though this is less of a concern with short term fasting.
