Yep, apparently it's a thing -

"Adults who are overweight but not quite obese may face an increased risk of developing a severe case of COVID-19, according to new advice from the Centers for Disease Control and Prevention.
The public health agency has long said that people who are obese are more likely to become severely ill if they have a coronavirus infection. The threat posed by being overweight is not as clear, but it was strong enough to be added to to the list of medical conditions that “might” put people at “increased risk for severe illness,” the CDC said."
It's been added to the list of "people who MAY have an increased risk" -https://www.cdc.gov/coronavirus/2019-ncov/need-extra-precautions/people-with-medical-conditions.html?CDC_AA_refVal=https%3A%2F%2Fwww.cdc.gov%2Fcoronavirus%2F2019-ncov%2Fneed-extra-precautions%2Fgroups-at-higher-risk.html
Overweight (BMI > 25 kg/m2, but < 30 kg/m2)
I haven't heard this. I've only heard of obesity being a problem. This was discussed ad nauseum with Trump's illness. as he is obese by any measure. All the experts I saw interviewed mentioned his obesity, not just being overweight. Maybe this is a thing but if it is I haven't heard it mentioned. And just being obese doesn't guarantee a terrible outcome -- again, look at Trump and the even much more obese Chris Christie. Both appear to be doing fine, though we don't know the accuracy of what Trump says we can better trust Christie and he also just got released from hospital. Not to dissuade the losing of weight, but we don't want to scare people to death, either. Anyone else out there hear this?
