How to calculate the basal energy expenditure of the individual
Basal energy expenditure (GEB) is the amount of energy our body needs to perform basic functions such as breathing, maintaining body temperature and performing metabolic activities. Calculate Geb is important to determine the amount of calories we should consume daily to maintain our current weight.
What is basal energy expenditure?
Basal energy expenditure is the amount of calories our body needs to keep vital functions at rest. That is, it is the minimum amount of energy we need to survive. GEB varies according to several factors, such as age, gender, weight, height and level of physical activity.
How to calculate basal energy expenditure?
There are different formulas for calculating GEB, the best known being the Harris Benedict formula. This formula takes into account sex, age, weight and height of the individual. See the formula below:
- For men: Geb = 66 + (13.75 x weight in kg) + (5 x height in cm) (6.75 x age in years)
- For women: Geb = 655 + (9.56 x weight in kg) + (1.85 x height in cm) (4.68 x age in years)
After calculating GEB, it is important to consider the individual’s level of physical activity to determine their total energy expenditure (GET). The GET is calculated by multiplying the GEB by the corresponding physical activity factor. For example, if the individual is sedentary, the physical activity factor is 1.2. If the individual practices moderate exercises, the physical activity factor is 1.55. If the individual practices intense exercises, the physical activity factor is 1.9.
To calculate the GET, simply multiply GEB by the physical activity factor. For example, if GEB is 1500 calories and the physical activity factor is 1.55, the GET will be 2325 calories.
Why calculate basal energy expenditure?
Calculating basal energy expenditure is important to determine the amount of calories we should consume daily to maintain our current weight. If we consume more calories than we spend, we gain weight. If we consume less calories than we spend, we lose weight. Therefore, knowing our Geb helps us set caloric consumption goals and control our weight in a healthy way.
In addition, calculating GEB is also useful for healthcare professionals, such as nutritionists and physical educators, who can use this information to develop personalized food and exercise plans for their patients.
Conclusion
Calculation of basal energy expenditure is important to determine the amount of calories we should consume daily to maintain our current weight. To calculate GEB, it is necessary to take into account factors such as sex, age, weight and height. In addition, it is important to consider the individual’s level of physical activity to determine the total energy expenditure. Knowing our Geb helps us to set caloric consumption goals and control our weight in a healthy way.
