## What is a Calorie, And why i should calculate my calories?

The calorie is a unit of energy from the caloric theory of heat. The large calorie, also called the food calorie, is the heat needed to raise the temperature of one liter of water by one degree Celsius. In comparison, the small calorie is the heat needed for the same temperature increase in one milliliter of water. 1 large calorie equals 1000 small calories.

## How our Calorie Calculator works

Our Calorie Calculator is designed to provide accurate and personalized results. Here's how it works:

### Harris-Benedict Equation:

• This was one of the first methods for calculating Basal Metabolic Rate (BMR). It was refined in 1984 for improved accuracy.
• For men: BMR = 13.397W + 4.799H - 5.677A + 88.362

•

For women: BMR = 9.247W + 3.098H - 4.330A + 447.593

W= weight in kilograms, H= height in centimetres, A= age in years

### Mifflin-St Jeor Equation:

• This newer method has surpassed the Harris-Benedict Equation in precision for most people, making it the preferred choice for BMR estimation.
• For men: BMR = 10W + 6.25H - 5A + 5

• For women: BMR = 10W + 6.25H - 5A - 161

W= weight in kilograms, H= height in centimetres, A= age in years

### Katch-McArdle Formula:

• This formula includes lean body mass in its calculations, making it especially accurate for those who know their body fat percentage.
• Men/Women BMR = 370 + (21.6 × Lean Body Mass kg)

W= weight in kilograms, H= height in centimetres, A= age in years
