3,500 calories is the approximate equivalent of one pound of weight.
So if you normally burn 1750 calories per day (10,500 calories per week) and you want to lose 1 pound of weight per week, you need to reduce your calorie-intake by 3,500 calories - or, 500 calories per day. This means consuming about 1250 calories per day.
It is true that one pound of fat equals 3500 calories, but while dieting you are going to lose both fat and muscle mass as well as water (water losses account for 40-50% of the weight loss during the first two weeks on a diet).
After the first two weeks, the most typical ratio of weight loss consists of 25% lean body mass (muscles and organs) and 75% fat mass.
To lose one pound of lean body mass, you need to lose only 500 calories! Do you now see the difference between 500 and 3500 calories?

Every person will need to under eat a different number of calories to lose one pound of bodyweight! It will take anywhere from 2000 to 3200 calories. Obese people might be able to lose 100% fat mass and in their case it would take 3500 calories per pound.
