What is the recommended daily kilojoules intake for an adult?

Answer 1

It is very difficult to place a digit on how much energy one should consume daily as many lifestyle, age and genetic factors affect this however basically: the more active you are the more energy you need. I have put down a few numbers to give you some sort of a scale however it really depends on the individual. The way to fin out if you are taking in to much energy is to look down at your tummy and honestly use common sense (you don't have to be smart to tell whether you are fat). If you don't have enough time to exercise, make time or reduce the kilojoules. (I included a child to give a greater perspective).

Average adult: 8700 KJ

Overweight/less active: <8700

Elite Athlete: <1200 KJ

Child (8-10): 4700

Answer 2

work in calories to maintain adult weight multiply your weight in pounds by 12. ie

200 lbs * 12 = 2400 calories. To increase your weight you would need to increase the factor of 12 to say 15 if you were a body builder you would need a factor of 18 to increase muscle size
