Use this free tool to find your daily calorie requirement.
The BMR Calorie Calculator uses your BMR ( Basal Metabolic Rate ) to calculate total daily energy expenditure ( TDEE ). The tool uses height, weight, age, gender and activity to calculate BMR using these three formulas Mifflin-St Jeor , Katch-McCardle & Harris-Benedict. Then the average BMR from these three formulas is used to calculate TDEE.
Knowing your TDEE can help you maintain, lose or gain weight. To lose weight consume less calories than your TDEE and the opposite to bulk. If the calories in your daily diet is equal to your TDEE then you can maintain your weight.
