Should race affect BMI guidelines? Doctors are split
Summary
Host Regina Barber explores the history and limitations of BMI with Katie Wu, a staff writer at The Atlantic. They discuss why this 19th-century metric fails to accurately assess health risks for diverse populations, particularly Asian Americans who often develop diabetes at lower weights. The episode examines the controversial "screen at 23" initiative and the pushback against using race as a medical variable. Finally, they debate potential alternatives, such as universal screening or body composition measurements, as medicine seeks more personalized and equitable diagnostic tools.
