Dear Countin' Cal, Theoretically, about 3500 calories equals one pound of body weight. This means that you'd have to take in 3500 fewer calories than you usually do, over a period of time, to lose one pound. Keep in mind, this is in theory; what happens in the real world can be very different.
This is the total number of calories you would need to maintain your current weight. Calculate Calories to Lose Weight. One pound of body fat is equivalent to 3,500 calories â which means a person must cut that many calories from her diet to lose a single pound. By eliminating 500 calories a day, she will lose one pound in a week. So, if your daily caloric need is 1917.9875 to maintain your weight, subtract 500 from that, and you'll have the number of calories you can consume each day and still lose a pound in one week. In this case: 1,417.9875 calories.
