Basal Metabolism Rate Calculator

1. Enter your height, weight, age, sex, and activity level.
2. Your "basal metabolic rate", "active metabolic rate", and "estimated energy requirement" will be calculated automatically.

Basal metabolism (basal metabolic rate) refers to the energy (kcal) used for breathing and maintaining body temperature, which are unconsciously performed in order to live.

The breakdown of all energy consumption in a day can be broadly divided into "basal metabolism (60-70%)", "active metabolism (20%)" generated by physical activity, and "heat production (10%)" from food. Of the three types of metabolism, "basal metabolism" uses the most energy.

"Basal Metabolism Rate Calculator (BMR)" is also called "Basal Energy Expenditure (BEE)".

The basal metabolic rate can be roughly calculated from height, weight, and age. The "Harris Benedict formula" is often used.

• Male: Basal metabolic rate = 66.47 + (weight (kg) x 13.75) + (height x 5.0 (cm)) - (age x 6.76)
• Female: Basal metabolic rate = 665.1 + (weight (kg) x 9.56) + (height x 1.85 (cm)) - (age x 4.68)

Active metabolism (active metabolism) is the sum of the basal metabolism and the active calories per day (kcal). It is the same as "total calories burned per day".

"Active metabolism (TDEE: Total Daily Energy Expenditure)" is calculated from the basal metabolism and "how much exercise do you do? (activity level)".

• Almost no exercise: metabolic rate = basal metabolism x 1.2
• Light exercise: metabolic rate = basal metabolism x 1.375
• Moderate exercise: metabolic rate = basal metabolism x 1.55
• Intense exercise: metabolic rate = basal metabolism x 1.725
• Very intense: metabolic rate = basal metabolism x 1.9

Estimated Energy Requirement is the amount of energy intake that can avoid energy deficiency and excessive risks for the purpose of maintaining and improving health.

"Estimated Energy Requirement (EER)" refers to the amount of energy intake required by a healthy person per day.

*In the calculations of this tool, the estimated energy requirement is calculated using "average activity coefficient" and "for men and women aged 18-64 with a standard body type."
