How is the Basal Metabolic Rate (BMR) Calculator and the Calorie Calculator utilized?

The Basal Metabolic Rate (BMR) and Calorie Intake can be calculated using the following formulas:

Harris Benedict Equation:

Male: 66.47 + (13.75 × weight in kg) + (5.003 × height in cm) - (6.755 × age in years)
Female: 655.1 + (9.563 × weight in kg) + (1.85 × height in cm) - (4.676 × age in years)

This equation uses weight, height, and age to estimate BMR for both males and females.

Mifflin St Jeor Equation:

Male: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
Female: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161

This equation is another widely used method for estimating BMR.

Calorie Intake Formula:

Calorie = BMR × Activity Level

The activity level is multiplied by the BMR to get the calories (kcal/day).

Activity Levels:

Little or no Exercise (1.2): Sedentary Activity Level
Light exercise or sports 1-3 times/week (1.375): Slight Activity Level
Moderate exercise or sports 3-5 times/week (1.55): Moderate Activity Level
Hard exercise or sports 6-7 times/week (1.725): Very Activity Level
Very hard exercise, sports or physical job or training twice a day (1.9): Extra Activity Level

What is Basal Metabolic Rate?

The minimal number of calories required by a person daily is theoretically known as a Basal Metabolic Rate (BMR). In layman terms, this is solely the number of calories the biological structures in your body need to function when your body is lying idle. Thus, the Basal Metabolic Rate Calculator helps you calculate the BMR.

Since your basal metabolic rate is based mainly on the body's involuntary functions like the respiratory and the circulatory functions, changes in the daily activities do not much raise or lower this number as the digestive system is inactive. However, an increased muscle mass does increase the BMR because muscle is metabolically "hungry" and it usually takes more energy to maintain more muscle.

What is a Calorie?

A calorie is a unit of energy. In terms of nutrition, calories refer to the energy consumed through eating and drinking and the usage of energy through physical activity.

Calories are typed into two:

At a pressure of one atmosphere, the estimated volume of energy required to elevate the temperature of one gram of water by one degree Celsius is rightfully known as a small calorie or a gram calorie. This is symbolized as cal.

Correspondingly, a large calorie or a kilogram calorie, which forms the second type, is merely 1000 small calories. It is predominantly expounded in terms of kilograms instead of grams. This is symbolized as Cal or kcal.

Our Calorie Intake Calculator can aid in determining how many calories are needed in a day and how many are needed to be cut off if one wants to lose weight. The tool can be used to estimate the number of calories a person needs to consume each day. Simple guidelines for gaining and losing weight can also be provided.
