Your body burns calories while carrying out basic (basic) life-sustaining tasks, or BMR. Frequently referred to as "Resting Metabolic Rate (RMR)" this phrase refers to the number of calories burned while resting in bed.
An average man has a BMR of around 7,100 kJ per day, while an average woman has a BMR of around 5,900 kJ per day.
Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years) Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)
In order to generate a caloric deficit, which is defined as ingesting less calories each day than you burn for energy, having an understanding of your BMR or RMR will help you more accurately estimate your total daily energy expenditure. To reduce weight, you must create a calorie deficit.
To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows: If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.
