How many kilojoules should an 18 year old girl have each day?

Answer 1

Calories provide energy, which we need to survive and perform daily activities. The calories we get from food and beverages allow us to breathe, walk, run, laugh and even pump blood. Calorie needs vary depending on age, sex, height and activity level. Calorie needs are often higher during the teenage years than any other time of life. During this period of rapid growth and development, boys require an average of 2,800 calories a day, while girls require an average of 2,200 calories a day.

Answer 2

You should be safe with around 8000-9000 kilojoules per day but it is highly relative to you personally and factors such as height, activity, age, gender and weight are inclusive in calculating how many kilojoules you should have.
