About Calorie Calculator
This tool uses scientific formulas to calculate your daily calorie needs, including Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE), with personalized macronutrient distribution recommendations.
Formulas
Mifflin-St Jeor Method: Male BMR = 10×weight(kg) + 6.25×height(cm) - 5×age + 5; Female BMR = 10×weight(kg) + 6.25×height(cm) - 5×age - 161
Harris-Benedict Method: Male BMR = 13.397×weight(kg) + 4.799×height(cm) - 5.677×age + 88.362; Female BMR = 9.247×weight(kg) + 3.098×height(cm) - 4.330×age + 447.593
Katch-McArdle Method: BMR = 370 + 21.6×lean body mass(kg), where lean body mass = weight×(1-body fat%/100)
