Increasing obesity in the United States and improvements in health and longevity outside the U.S. contributed to lowering the country's rank in life expectancy from 11th in the world in 1987 to 42nd in 2007. In 2017, the United States had the lowest life expectancy among Japan, Canada, Australia, the United Kingdom, and seven nations in western Europe. Obesity rates have more than doubled in the last 30 years and are the highest in the industrialized world. Approximately one-third of the adult population is obese and an additional third is overweight. Obesity-related type2 diabetes is considered epidemic by health care professionals.
