It is hard to know the answer to this question. First, you will need to know your age, height, weight, and how active you are. You will also need to know how healthy your metabolism is.

If you want to lose weight, use a thumb rule: eat 500 fewer calories than your body needs every day for one week. This could lead to one pound (0.45 kg) less per week.

The average woman needs to eat about 2,000 calories per day to stay the same weight and 1,500 calories per day to lose 1 pound of weight. Women who walk more than 3 miles need 2,200 calories or more each day, and women who are not as active at least 1,700.

Women in their 20s need more calories. They need 2,200 calories each day to maintain their weight. Older women need fewer calories. The average woman over 50 needs 1,800 calories per day to maintain her weight and 1,300 to lose 1 pound per week.


The average, moderately active man between the ages of 26–45 needs 2,600 calories per day to maintain his weight and 2,100 calories per day to lose 1 (0.45 kg) pound per week. Active men who walk more than 3 miles may need 2,800-3,000 calories per day to maintain their weight and 2,300-2,500 calories per day to lose 1 pound (0.45 kg) of weight each week.

Young men need about 2,800 calories every day to stay the same weight and up to 3,000 if they are active. For example, if a young man wants to lose one pound per week (0.45 kg), he should eat between 2,300-2,500 calories each day.

Men need more energy as they age. For example, between the ages of 46 and 65, a moderately active man needs about 2,400 calories per day. However, after 66 years, his energy needs decrease to about 2,200 calories per day.

Children have different calorie needs. For example, a toddler may need 1,200 to 1,400 calories per day. At the same time, a teen might need 2,000 to 2,800 calories per day. But, of course, teen boys would need even more than that.

Children who are growing and developing normally don’t have to count the number of calories they eat each day. Instead, they go by how hungry they feel and what their bodies tell them is needed for energy and growth.

What are Calories?

Calories measure how much energy you have. The amount of energy you need depends on your age, your lifestyle, and your size.

Other things can affect how much energy you have. For example, some hormones and medicines. These might make you tired. And if you are sick, it will be hard to have the energy you need.

Calories and Kilocalories

A calorie is a measurement of food. You will see this written as “kcal” on food items. The equivalent of one calorie within the International System of Units is called a “kilojoule.” So when you see kilojoules and calories together, it can mean either kilocalories or joules.

Losing Weight

To lose weight healthily, you need to use more energy than the amount of food you eat. You can do this by eating a diet that has fewer calories and becoming more active.

Gaining weight

If your BMI is under 18.5, you should get advice from a GP. This is because you may be underweight and need help to gain weight.
