The dream of every young lady in the past was to find a prince enchanted in a white horse, but with modernity everything changed, with the sedentary life, the lack of physical activity, today what every young girl wants is to have the body of her dreams, however for this you need some healthy efforts like eating properly and a few exercises that are the recipe of success for a healthy body.
Body mass index
Let's start with the BMI (Body Mass Index) which is the following formula.
BMI = weight: height x height
Example: Female 36 years old, businesswoman, 1.73 tall, weight 81 kg, sedentary
BMI = 81: 1.73 x 1.73
BMI = 81: 2.99
BMI = 27.09
Classification of BMI
Minor 18.5 | Low weight |
18,5 β 24,9 | Normal |
25,0 β 29,9 | Overweight |
30,0 β 34,9 | Obesity degree I |
35,0 β 39,9 | Obesity grade II |
Above 40.0 | Obesity grade III (morbid) |
Energy needs for each person
So let's calculate the energy needs that takes into consideration age and weight. Basal Metabolism (MB) (WHO, 1985)
Men's
Age | Formula |
---|---|
10 - 18 years | 17.5 x WEIGHT + 651 |
18 - 30 years | 15.3 x WEIGHT + 679 |
30 - 60 years | 11.6 x WEIGHT + 879 |
over 60 years | 13.5 x WEIGHT + 487 |
Women
Age | Formula |
---|---|
10 - 18 years | 12.2 x WEIGHT + 746 |
18 - 30 years | 14.7 x WEIGHT + 496 |
30 - 60 years | 8.7 x WEIGHT + 829 |
over 60 years | 10.5 x WEIGHT + 596 |
Continuing our example:
MB = 8.7 x WEIGHT + 829
MB = 8.7 x 81 + 829
MB = 704.7 + 829
MB = 1533.7
Calculation of Total Energy Value (TEV)
Where we multiply the MB by (FA) Activity Factor
Men's | Women |
1,55 - Light: for executives, teachers, professionals, housewives. 1.78 - Moderate: for work in light industry, drivers, students. 2,10 - Intense: for non-motorized farmer, soldier, athletes. | 1,56 - Light: for executives, teachers, professionals, housewives. 1.64 - Moderate: for work in light industry, drivers, students. 1,82 - Intense: for non-motorized farmer, soldier, athlete. |
Taking advantage of the same example:
VET = MB x FA
VET = 1533.7 x 1.56
VET = 2392,57 kcal - 400 kcal = 1992, 57 kcal rounding 2000 kcal
This is the calorific value that this executive has to ingest daily, - 400 kcal for those who want to eliminate weight.
