Age and gender information are needed because dietary requirements vary among different age and gender groups. Weight information is used to find out your energy used during physical activity. Please record your actual weight as correctly as possible to give you an accurate result of your physical activity status. The HEI and nutrient intakes are based on a person who is moderately active.
