This calculation yields your target fat calorie range. For a man or woman on a 2,000-calorie diet, the target fat-calorie range is 400 to 700 calories. Fat contains nine calories per gram, so divide each number of the fat-calorie range by nine to determine your daily fat grams. For a 2,000-calorie per day diet, the recommended daily fat intake is 44 to 78 grams. The recommended daily fat amounts for 1,500-calorie and 2,500-calorie diets are 33 to 58 grams and 56 to 97 grams, respectively.
