How to diagnose obesity?
Women have more
body fat than men. Men with more than 25% body fat and women with more than 30%
body fat are obese.
We can diagnose
obesity by BMI (Body Mass Index), which is used to determine the type of
obesity. BMI is an inexpensive and easy-to-perform method of screening for
weight categories that may lead to health problems. It is a measurement of
a person’s weight relative to his or her height.
Example:
Weight = 77 kg,
Height = 179 cm (1.79 m)
Calculation: 77 ÷
(1.79)2 = 24
For most adults, having a
BMI of 18.5 to 24.9 means you are considered to be a healthy weight.
A person with a BMI
of 25 to 29.9 is considered to be overweight, and someone with a BMI over 30 is
considered to be obese.
While BMI
is an accurate assessment of total body fat in most people, there are a
few exceptions. Such as very muscular people, they may fall into the
“overweight” category when they are actually healthy and very fit because
of increased muscularity rather than increased body fatness.
BMI also should not be used to work out if a child
is a healthy weight, as their bodies are still developing. If you want to find
out whether your child is overweight, you should speak to your GP.
However, a person’s BMI score is not the only tool
used by healthcare professionals to assess health risk. They also consider
waist circumference, blood pressure, cholesterol level, blood sugar level,
family history of disease, physical activity, and cigarette smoking when
assessing a patient’s health risk.
Body Fat Distribution:
Men collect fat in their bellies (apple shape),
so they are more likely to develop obesity-related health problems.
Women collect their fat in their buttocks and hips
(pear shape), this kind of obesity is less dangerous than men obesity.
Apple shape (bellies obesity) is more dangerous than
pear shape (buttocks and hips obesity).
A waist measurement for men
shouldn't exceed 40 inches (102 centimetres), and for women 35 inches
(89 centimetres).
Remember, even a small weight loss can help to (between 5 and 10
percent of your current weight) lower your risk of developing certain
diseases.
