Calculating Calories and Fat Grams
To determine the number of calories and fat grams you need to consume each day in order to lose or gain weight, consult your physician or a registered dietitian. To maintain your current weight, follow the formula below.
1. Write your body weight in the equation that fits your activity level and gender. Then, multiply.
a) Moderately active male:
_____ pounds x 15 calories = _____ total calories per day.
b) Moderately active female:
____ pounds x 12 calories = _____ total calories per day.
c) Relatively inactive male:
____ pounds x 13 calories = _____ total calories per day.
d) Relatively inactive female:
____ pounds x 10 calories = _____ total calories per day.
2. Take total calories and multiply by 30 percent.
____ calories per day x . 30 =
____ calories from fat per day.
3. Take calories from fat per day and divide by 9
(there are 9 calories per gram of fat):
____ calories from fat per day divided by 9 =
____ fat grams per day.
Remember, saturated fats should account for only 10 percent of the total fat grams consumed.
