Count your calories for free!

BMR- Basal Metabolic Rate is the number of calories your body burns at rest to maintain normal body functions. It is the amount of calories per day your body burns, regardless of exercise. It changes with age, weight, height, gender, diet and exercise habits.However, a regular routine of cardiovascular exercise can increase your BMR, improving your health and fitness when your body's ability to burn energy gradually slows down.

Daily caloric needs - Your caloric intake is the amount of calories your body expends each day through routine activities and performing bodily functions such as breathing, circulation, and metabolism. And therefore the number of calories you could eat per day to maintain your current weight. If your goal is to lose weight by burning off excess body fat, aim to eat 500 fewer calories per day than your daily caloric needs, and maintain or increase your exercise activity. Do not go below 1200 calories per day unless you are on a medically supervised weight loss program or after consultation with your doctor.

BMI - A standardized estimate of an individual’s relative body fat calculated from his or her height and weight. Calculating BMI is one of the best methods for population assessment of overweight and obesity. Because calculation requires only height and weight, it is inexpensive and easy to use for clinicians and for the general public. The use of BMI allows people to compare their own weight status to that of the general population.

Calculate your BMI, BMR and caloric needs. Just enter your weight, height, sex, age and physical activity. Knowing your personal BMI, BMR and caloric intake lets you fine tune a weight loss, weight gain or weight management program. We recommend to use this calculator for people over 20 years old only. It can not be precise for pregnant woman, children and adolescent, older people and elite athletes also.
