The calculator below gives an idea of how many calories are needed for a person of a given age, gender, build and level of daily activity to maintain a given weight level.
If more calories are consumed, then unless extra physical activity is undertaken, body weight will increase.
See here for a guide as to how many calories are being consumed daily.

If, for example, a person is consuming - eating - 2250 calories a day, but needs only 2000 calories daily by leading 'light active' lifestyle, then the extra 250 calories have to be eliminated otherwise the extra calories will be stored in the body as fat.

There are two ways of eliminating these extra calories:

• By eating less food
• By taking a brisk walk for about an hour or engaging in other exercise

These calculators will help in better weight management.
