Calcula tu Tasa Metabólica Basal — las calorías que tu cuerpo quema en reposo.
This BMR calculator estimates the number of calories your body burns at complete rest using two established formulas: the Mifflin-St Jeor equation (1990) and the revised Harris-Benedict equation (1984). Your BMR accounts for about 60-75% of your total daily energy expenditure.
