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.
To gain one pound per week increase your required calories by 500 per day (500 calories X 7 days per week = 3500 calories) The American College of Sports Medicine recommends a minimum of 1200 calories per day for females and 1800 calories per day for males.
