A new study published Wednesday has revealed that rising levels of obesity are set to cost the world economy 3.3 percent of GDP by 2060, slowing development in lower-income countries and making it hard for people to lead healthy lives. The peer-reviewed paper provides the first country-by-country estimate of the economic impacts of obesity, a major driver of other non-communicable diseases such as cancer, diabetes, and heart conditions. Globally, nearly two in three adults are now living with overweight and obesity.
