Can you tell me what number of calories does a 16 1/2 year old girl need?

See Your Doctor: You ask "number of calories" for 16.5 yr girl? Unlike other age groups, adolescent nutritional needs are determined by the degree of pubertal maturation & other biological factors. Also there is no established energy (calorie) intake level for this age, however estimates can be made based on height, weight, & physical activity. See your child's doctor for exam & determination of nutritional needs.
