Definition: A calorie is a measure of energy expenditure. The calories referred to in diet and exercise are kilocalories (kcal) - 1000 of the calories referred to in science labs for measuring chemical reactions.

A pound of fat stores 3500 calories (kcal). To lose a pound of fat a week a person must eat approximately 500 fewer calories (kcal) per day than he/she expends.

The range of daily calorie burning is from 1600 for a sedentary woman or older people to 2800 for active men, very active women and teenage boys.

Walking expends approximately 100 calories per mile for a 150 pound person.
