People need different amounts of energy and it again depends on you and something called your metabolic rate (the rate in which metabolism lives in a living organism or the speed of chemical reactions in the body), therefore things that impact on the rate include age, gender, if you are male or female and the proportion of muscle to fat in your body.

Weight depends on the balance between energy you consume from your food and drink

In the UK the majority of people have been classed as either overweight or obese.

So how many calories should we have every day?

Men need around 10,500KJ (2,500Kcal) a day to help maintain a healthy weight.

For woman it is around 8,400KJ (2,000Kcal) a day.
