Not just a big belly; an epidemic that has friends
Rahman Mohamed
According to the World Health Organization (WHO), in 2008 more than 1.4 billion adults on Earth over the age of 20 were overweight; over 500 million of them were obese. In 2011 more than 40 million children under age 5 were overweight. That means that those who overweight had a Body Mass Index (BMI) more than 25, while those who were obese had a BMI over 30 (weight divided by height squared in metric – kg/m2).
What does obesity do to you?
