FIGURE 1 | Obesity prevalence in US adults (20–74 years).

Obesity is described on the basis of the normalizing measure called the body mass index (BMI). BMI is calculated by dividing a person's weight (in kilograms) by the square of that person's height (in metres). A normal BMI is below 24.9 kg m^-2. An individual who has a BMI of 25–29.9 kg m^-2 is considered 'overweight,' and a BMI of greater than 30 kg m^-2 is considered to be 'obese.' Source: National Health and Nutrition Examination Survey
