BMR, or basal metabolic rate, is one of the most widely used parameters for defining the preferred calorie ratio. For our calculator plugin, we use the Mifflin—St. Jeor formula. It identifies BMR by analyzing the essential features of your organism: body mass, height, age, and biological sex. The plugin calculates the daily calorie consumption rate using those numbers with the multipliers needed to account for the goals and conditions. The formula also takes sports and other types of activity into account: this way, the users can be sure that the calorie norm offered by WP Calorie Calculator corresponds with their individual physical characteristics such as weight, height, and others. Among the advanced features of the WP Calorie Calculator Pro plugin, there are custom functions such as macronutrient balance and activity level—both editable and removable! In addition, the Pro version has as many as three formulas available and calculates such crucial parameters as BMI & BMR.
