'This recommendation is reasonable and in line with the evolution of medical consensus'

'Why a proposal to change the definition of obesity is so controversial'

BMI has a "flaw, because it doesn't account for all the factors that determine whether someone's weight is healthy, including their race or ethnicity," says Leana S. Wen.
