What is a Calorie?
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.
1 kg is equivalent to 7700 kcal.

How to Calculate my Calories
The GymNation Calorie Calculator utilizes different equations to provide estimated results learn HOW TO USE A CALORIE CALCULATOR TO HIT YOUR HEALTH AND FITNESS GOALS now. Originally, the Harris-Benedict Equation, an early BMR calculation method, was refined in 1984 for greater accuracy. The more recent Mifflin-St Jeor Equation has since surpassed it in precision. The Katch-McArdle Formula incorporates lean body mass for RDEE calculation, setting it apart from the other equations. While the Mifflin-St Jeor Equation is generally favored for BMR estimation, it may not be ideal for lean individuals who know their body fat percentage. The three equations employed are as follows:
Mifflin-St Jeor Equation
For men: BMR = 10W + 6.25H - 5A + 5
For women: BMR = 10W + 6.25H - 5A - 161
Katch-McArdle Formula:
Men/Women BMR = 370 + (21.6 × Lean Body Mass kg)
Revised Harris-Benedict Equation
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
