原文

With obesity a factor in Covid-19 vaccine eligibility, many Americans are scrambling to find out their body mass index, or BMI.

But experts say the meaning behind those numbers -- and how to lower them -- isn't always so clear-cut.

The US Centers for Disease Control and Prevention lists obesity as an underlying medical condition, and defines it as someone who has a body mass index of 30 or higher but less than 40. Having a high BMI, however, doesn't necessarily mean you're unhealthy.
