Understanding the metabolic rate is essential for several reasons: - Growth and Development: Children have higher metabolic rates than adults due to the energy needed for growth. Proper energy intake is vital for normal physical and cognitive development. - Nutritional Needs: Accurate calculation of metabolic rate helps in devising appropriate dietary plans, ensuring children get sufficient nutrients. - Medical Conditions: Certain medical conditions, such as hypothyroidism or hyperthyroidism, can affect the metabolic rate. Recognizing these changes can lead to early diagnosis and treatment.
