In 1998, the U.S. [[National Institutes of Health]] brought U.S. definitions in line with [[World Health Organization]] guidelines, lowering the normal/overweight cut-off from a BMI of 27.8 (men) and 27.3 (women) to a BMI of 25. This had the effect of redefining approximately 25 million Americans, previously ''healthy'', to ''overweight''.

This can partially explain the increase in the ''overweight'' diagnosis in the past 20 years~~{{when|date=February 2023}}~~, and the increase in sales of weight loss products during the same time. [[World Health Organization|WHO]] also recommends lowering the normal/overweight threshold for southeast Asian body types to around BMI 23, and expects further revisions to emerge from clinical studies of different body types.

A survey in 2007 showed 63% of Americans were then overweight or obese, with 26% in the obese category (a BMI of 30 or more). By 2014, 37.7% of adults in the United States were obese, 35.0% of men and 40.4% of women; class 3 obesity (BMI over 40) values were 7.7% for men and 9.9% for women. The U.S. National Health and Nutrition Examination Survey of 2015-2016 showed that 71.6% of American men and women had BMIs over 25. Obesity—a BMI of 30 or more—was found in 39.8% of the US adults.
