More than 2.1 billion people, or close to 30 percent of the global population, are overweight or obese, and obesity is responsible for about five percent of all deaths each year, worldwide. In the US, nearly one in five deaths is now associated with obesity.
That obesity factors into your mortality risk isn't so surprising when you consider just how many chronic and serious disease it's associated with.
In the US, just eight obesity-related diseases account for 75 percent of all healthcare costs! Type 2 diabetes, hypertension, heart disease, non-alcoholic fatty liver disease (NAFLD), dementia, and cancer are among them, but there are many others as well.
