Around 30 percent of the world’s population is now obese, while 50 percent is expected to fall into the category by 2030. Meanwhile, 5 percent of global deaths each year are linked to the condition, creating a drag on the global economy.
A new report by the McKinsey Global Institute (MGI) revealed the not-so-hidden cost of an increasingly sedentary population that has acquired a bad taste for fast food, and sitting for long stretches of time in traffic jams and office buildings.
More than 2.1 billion people are now clinically obese. According to the World Health Organization, 65 percent of the world's population lives in countries where obesity kills more people than being underweight.
In addition to the deadly impact of obesity is the impact on the global economy, which comes out to be about $2 trillion annually, or 2.8 percent of global GDP.
The report revealed the global cost of obesity to be “nearly equivalent to the global impact of smoking or of armed violence, war, and terrorism.”
"Obesity isn't just a health issue," the report's lead author Richard Dobbs said in a podcast. "But it's a major economic and business challenge."
Perhaps the most incredible thing about obesity is that it has nearly doubled since 1980 and, according to MGI, “is rapidly getting worse.”
“If the prevalence of obesity continues on its current trajectory, almost half of the world’s adult population will be overweight or obese by 2030,” it said.
After examining a number of plans to tackle the problem of obesity, the report confirmed that nearly all result in some sort of savings, for example, in lower healthcare costs for treating diseases connected to obesity and more productivity in the workplace.
It pointed to the United Kingdom, where intervention efforts “could reverse rising obesity, saving the National Health Service about $1.2 billion a year.”
Plans to reduce the global epidemic of global obesity will take much more than just education and personal responsibility, although these are essential factors as well, the researchers write. A solution to the problem will “rely less on conscious choices by individuals and more on changes to the environment and societal norms,” the report said.
Changes must occur in a number of places, including in restaurants that provide “default portion sizes,” to “marketing practices” that target children and adults with advertising. It also suggests “restructuring urban and education environments” to allow for physical activities.
