How many kilojoules should a person eat a day?

Answer 1

Adult Males 2500 Calories which is 10 500 kilojoules. Adult Females 2000 Calories which is 8 400 kilojoules. That is for an average lifestyle, it will go up or down depending on how much or little physical activity you do.

Answer 2

It depends what the exercise is. Don't worry about it, as long as they are fit, happy and healthy let the appetite be a guide, just give them a wide variety of healthy food. They will eat anything they can lay their hands on so make sure the fridge and larder are always well stocked with things that are good for them to eat. See the www associated with this answer

Answer 3

7

We have learnt, that kids like 12 years old need about 9,000 joules a day and I think, that when the teenagers are more teeny-tiny, that they need more energy so about 10,000 is my answer, so my answer is 10 .

Answer 4

The nutritional requirements for a teenage male should be an average of 3000kj a day and a teenage female should be an average of 2500kj a day, considering their developmental needs and activeness.

Answer 5

An average person needs about 11 calories per pound of body weight per day. A 150 pound person needs about 1650 food calories a day. (Food calories are actually kilocalories.) Because it is normal for teens to slowly gain weight as they finish growth and development, and because many teens have very active lifestyles, there is a wide range of reasonable calorie intake. A growing boy on the swim team or cross country team might take in 3000 calories daily.
