More than one-third Americans are obese, compared to one-quarter in Canada
More than one-third of Americans are obese, as are one-quarter of Canadians, according to research by the U.S. Centers for Disease Control. Their study found obesity has grown a lot over the past two decades, Reuters reports, but when comparing only non-Hispanic white populations in both countries, the authors found that 25.6% of Canadians were obese, compared to 33% in the U.S. Reasons for this difference are unclear, and require further study. Overeating, poor diet, and physical inactivity are generally thought to be major causes behind the obesity epidemic.
