What Is Obesity? Why Is It Important?
Obesity is becoming increasingly common all over the world and constitutes an important health problem. Data from the World Health Organization shows that 1.9 billion people are obese worldwide and emphasizes that the number of overweight individuals has doubled since 1980. These data show that obesity is a very common health problem all over the world and that if no measures are taken, it will increase gradually.
BMI compares your weight to your height, and is calculated by dividing your weight (in kilograms) by your height (in metres squared). It gives you an idea of whether you’re 'underweight', a 'healthy' weight, 'overweight', or 'obese' for your height. BMI is one type of tool to help health professionals assess the risk for chronic disease.
