How Many Calories Do You Need?

Whether you're trying to lose weight, gain weight, or stick to your current weight, you might be tempted to look up the suggested calories per day for your gender, age, and activity level.

Daily Calorie Intake

Your daily calorie intake is the approximate number of calories you should try to eat each day. It varies widely from person to person. The chart below shows some ways to estimate yours. The chart should only be used as a reference point because every person is so different metabolically even when they are the same size and gender. The following suggested calorie ranges are generated using the Institute of Medicine’s estimated energy requirement calculation.

a These levels are based on Estimated Energy Requirements (EER) from the Institute of Medicine Dietary Reference Intakes macronutrients report, 2002, calculated by gender, age, and activity level for reference-sized individuals. "Reference size," as determined by IOM, is based on median height and weight for ages up to age 18 years of age and median height and weight for that height to give a BMI of 21.5 for adult females and 22.5 for adult males.

b Sedentary means a lifestyle that includes only the light physical activity associated with typical day-to-day life.

c Moderately active means a lifestyle that includes physical activity equivalent to walking about 1.5 to 3 miles per day at 3 to 4 miles per hour, in addition to the light physical activity associated with typical day-to-day life.

d Active means a lifestyle that includes physical activity equivalent to walking more than 3 miles per day at 3 to 4 miles per hour, in addition to the light physical activity associated with typical day-to-day life.
