What are caloric expenses?

caloric expenditure is the amount of energy used by the body over a period of time. Everything the body does require energy. Although he sleeps, the body still carries out countless processes, including breathing, digestion and healing. Calories expenditures are for every activity and each individual, depending on a number of factors, including age, weight and gender. When food is listed as 300 calories, it means that it contains 300 units of energy. When it is said that activity burns 300 calories, it means that the body uses 300 units of energy to complete the activity.

Estimating calories is important for many different reasons. Doctors use it to determine how much nutritional support they need critically ill patients. Bodybuilders use it to determine how much food to eat to support muscleWTH and use dieters to determine how much food they support fat loss. Calculation of the base is called total daily energy expenditure (TDEE) and is the total energy that the body must work within 24 hitsn. Calorie intake under TDEE will result in weight loss and caloric intake over TDEE will lead to weight gain.

There are many different methods of determination of TDEE, with different degrees of accuracy. The simplest method for individuals looking for a rough estimate is to multiply body weight 15. The result is a very basic estimate of TDEE, which is most likely not very accurate. When calculating caloric needs and expenditure, it is important to consider many factors, including the composition of the body.

The Harris Benedict equation is an equation that doctors and fitness experts are widely used because of its overall accuracy. This method takes many factors, including basal metabolic speed (BMR), which is caloric body expenditure only for performing basic body functions, with the exception of physical activity. In addition, the calculation includes a "multiplier of activity". which fine tons for physical activity.

First BMR is calculated differently in men and women:

men: BMR = 66+ (13.7 x weight in kg) + (5 x height in cm) - (6.8 x age in years)

Women: BMR = 655+ (9.6 x weight in kg) + (1.8 x height in cm) - (4.7 x age)

Furthermore, the BMR is multiplier by a multiplier of activity, which ranges on a scale of 1.2 for a sedentary person to 1.9 for a professional athlete. For example, if a 32 -year -old woman was 5'4 ”(about 1.6 meters), she weighed £ 130 (about 59 kg) and performed a slight exercise four days a week, equation would be:

BMR = 655 + (9.6 x 59 kg) + (1.8 x 162.6 cm) - (4.7 x 32) = 1363.68

tdee = 1363.68 x 1.6 = 2181.888

Harris Benrovnice Edition is accurate for most people, but because it does not take into account slim body, it is not accurate for extremely muscular and extremely obese. For these two groups, doctors use Katch-Mcardle formula, which is the same for both men and women:

BMR = 370 + (21.6 x kg lean weight)

formula katThe CH-Mcardle relies on the composition of the body designated by the doctor and creates a more accurate picture of the daily caloric needs of these patients.
