Obesity is one of leading risk factors of premature death according to the WHO. This figure shows the obesity rate for the G20 countries from 1975 to 2016. Obesity is defined as everyone with a BMI (Body mass index) of above 30.
This figure shows that there is a steady increase in the number of obese people in the world, without an indication of slowing down. An interesting observation is how well Asian countries do it compared to the rest of the world.
