How many calories do you need to eat in a day to maintain your current weight? That’s different for each and every individual.
This calculator uses the formula for Basal Metabolic Rate (BMR) devised by doctors at the University of Nevada Medical School and published in the American Journal of Clinical Nutrition in 1990, then uses the Harris Benedict activity multiplier to determine your estimated daily caloric burn off.
The Basal Metabolic Rate is how many calories you would need to maintain your body weight if all you did all day was lay in bed and your only activity was eating. Just sitting up and typing a a few hours a day, walking from the couch to your car, from the car to your office, etc. boosts your daily needs up by 20%. If you lead a lifestyle where you have high levels of exertion every day, it can nearly double your calorie needs.
Just fill out the fields in the form below and click “calculate my calorie needs” to get your BMR and your daily calorie needs.
