The calorie is the unit we use to measure our body's metabolic rate - how fast it burns food to get energy. The caloric value on food labels lets you know how much energy you get by eating a given amount of that food. But how many calories do you need to fuel your daily activities? If you consume more calories than you need, your body stores the extra energy as fat.

Many sources suggest that women need 2,000 calories a day and men need 2,500. Such general figures do not take into consideration your individual body type or lifestyle. Here's a quick way to determine your personal calorie goal.
Divide your current weight in pounds by 2.2 to get your weight in kilograms (because calories are measured in kilograms).
Multiply your weight in kilograms by the appropriate number below:
* 15 if you are not active (if you sit most of the day) ,
* 20 if you are somewhat active (do housework, garden, walk) ,
* 25 if you exercise (some exercise 3 to 4 times a week) , and
* 30 if you are very active (you get exercise every day).

This calculation will give you an estimate of how many calories you need to eat every day to maintain the weight you are at now.

If there is a balance between your caloric intake and your activity level, you will maintain your weight. If you eat fewer calories and increase your activity level, you will lose weight. If your caloric intake increases and your activity level does not you will probably gain weight.

Remember, every body is different and these are only guidelines. If you want more specific information or a more thorough review of your energy balance, contact your healthcare provider or a registered dietitian.
