Calculadora BEE (Basal Energy Expenditure)

The BEE (Basal Energy Expenditure) Calculator determines the basal energy expenditure, also known as Basal Metabolic Rate (BMR). It uses the revised Harris-Benedict formula, which takes into account sex, weight, height, and age to estimate how many calories the body burns at complete rest. This value is essential for planning weight loss, muscle gain, or weight maintenance diets.

It works simply: enter your data in the provided fields and the calculator applies the revised Harris-Benedict equation. For men: 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years). For women: 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years). The result is the number of calories burned per day at rest.

Use this calculator when you need to know your basal metabolism as a starting point for personalized diets. For example, a nutritionist can use the BEE to set a safe calorie deficit. Athletes and physically active individuals also benefit by adjusting their calorie intake based on total daily expenditure.

Important caveats: the result is an estimate and varies from person to person. Factors such as body composition (muscle mass vs. fat), genetics, and medical conditions (like hypothyroidism) can alter metabolism. Never use BEE as the sole reference for restrictive diets without professional supervision.
