Counting the calories you eat is a little different. A gram of protein has 4 calories, as does a gram of carbohydrate. But a gram of fat has 9 calories, and a gram of alcohol has 7. There are roughly 454 grams in a pound, so: 1814 calories in a pound of pure protein or carbohydrate.
Recall that 1 pound (~0.45 kg) equates to approximately 3500 calories, and reducing daily caloric intake relative to estimated BMR by 500 calories per day will theoretically result in a loss of 1 pound a week.
