The following Quick-Estimate-of-Calorie-Needs is exactly that. It doesn't allow for factors like metabolic rate, age or body fat percentage. So don't use it as an exact calculation of calorie requirements - it's simply a ball-park calorie assessment. If you want a more precise calculation of your daily energy needs, click the calorie links above or below.

Note: Whatever your weight loss requirements, it is best to eat a minimum of 1200 calories (women), or 1600 calories (men).

Quick Estimate of Calorie Needs for Women
If moderately active, multiply your current weight in pounds by 15.
If typically inactive, multiply your current weight in pounds by 13.

Calorie Needs Example
Joni weighs 240 pounds and leads a typically inactive life.
Her ball-park daily calorie needs are 240 x 13 = 3120 calories.

This is the total number of calories she needs in order to MAINTAIN her current weight.

Kilos

If moderately active, multiply your weight in kilos by 22, then multiply by 1.5.
If typically inactive, multiply your current weight in kilos by 22, then multiply by 1.3.
