BMI or Body Mass Index was first discovered in 1834 by Adolf Cutlet, a Belgian statistician. He never thought this number would ever be this much comprehensive. This index is calculated according to the individual’s height and weight. For example for a person with a height of 173 centimeters and 84 kg, it would be calculated as follows:
BMI = Weight / height ^2
If the obtained value is:
- Less than 18.5 the person is underweight.
- Between 18.5 and 24.9 the person has a normal weight.
- Between 25 and 29.9 the person is overweight.
- More than 30 the person suffers from obesity.
Consider that BMI is an index to determine individual’s condition quickly and easily. If a person’s BMI is more than the normal value, the risk of cardiovascular diseases and diabetes increases. This value is different according to the individual’s race. For example if the BMI of a person in South East Asia is more than 24, the person is overweight. Apart from BMI, there are other indices to determine and screen the individual’s health status, the most important one being the waist to height ratio.
If the obtained value is:
- Less than 0.49 the person is normal.
- Between 0.50 and 0.59 the person should come up with ideas to burn the fat around his/ her waist.
- More than 0.6 the person should start burning the fat around his/ her waist.
According to the studies conducted by the World Health Organization, if men’s and women’s waist is more than 102 and 88 cm, respectively, the risk of type 2 diabetes, blood pressure, high cholesterol and heart diseases will be high due to the abundant fat around their waist. Therefore, they should try losing weight.
One of the most difficult phases in anyone’s life is losing weight, the main requirement of which is motivation and strong will. The first requirements are willpower and motivation. The second is to define the goals logically and achievable.
The third one fact is that losing weight is only possible by exercising along with a diet appropriate for body metabolism.
Never go for deceptive slimming pills or compounds because they will result in the destruction of liver and kidneys.
The amount of calorie needed in body (BMR) is calculated by Harris- Benedict formula as follows:
BMR (Women) = 655 + (9.6 × weight) + (1.8 × height) – (4.7 × age)
BMR (Men) = 66 + (13.7 × weight) + (5 × height) – (6.8 × age)
The more the body activity, the more the calories required by the body will be.
BMR × 1.2 for inactive individuals
1.375 × BMR (exercising about 1 to 3 days a week) low- active individuals
BMR × 1.55 (moderate exercising about 3 to 5 days a week) moderately active individuals
BMR × 1.725 (daily exercising) active individuals
1.725 × BMR highly active individuals
These numbers should be multiplied by BMR in order to obtain the required calories of the body.
