Energy Calculations

Energy Calculations

Energy Calculations, basically are the calculation of daily energy expenditures by an individual i.e. BMR, BMI, RMR etc.

Total Energy Expenditure

Total energy expenditure (TEE) is the sum of basal energy expenditure, activity thermogenesis, and the thermic effect of food; the daily total energy expended by a person in 24 hours.

Energy expenditure is the amount of energy (or calories) that a person needs to carry out a physical function such as breathing, circulating blood, digesting food, or physical movement. Your total daily energy expenditure (TDEE) is the total number of calories you burn each day.

Here are the different types of total energy expenditure that an individual consumes on daily basis;

•      Basal energy expenditure

•      Basal metabolic rate

•      Resting metabolic rate

To prevent weight gain, energy intake or calorie intake must be balanced with energy expenditure.

The question is how to calculate energy??

The answer is given by Harris Benedict. He gave different equations for both genders.

Actually these equations are for calculating BMR. After finding BMR we have to multiply it with our Activity Factor i.e. Sedentary, Active or Very active.

Here the different activity factors are given:

• Sedentary  = 1.1
• Active       = 1.2
• Very Active = 1.3
  

Harris–Benedict equation. The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).

Note:

• Weight should be in kilograms (kg).
• Height should be in centimeters (cm).
• Age should be in years.
