More than two-thirds of Americans are either overweight or obese, a major new study has found.
Researchers from the Washington University School of Medicine, St Louis, analysed data from the National Health and Nutrition Examination Survey from 2007 to 2012 to estimate the prevalence of overweight and obesity.
They collected data for 15,208 men and women 25 or older, a sample that was representative of more than 188 million people.
The study by Graham A Colditz and Lin Yang estimates that 39.96 per cent of men (36.3 million) and 29.74 per cent of women (almost 28.9 million) were overweight and 35.04 per cent of men (31.8 million) and 36.84 per cent of women (nearly 35.8 million) were obese.
"Population-based strategies helping to reduce modifiable risk factors such as physical environment interventions, enhancing primary care efforts to prevent and treat obesity, and altering societal norms of behaviour are required," researchers said.
