And in the general population?

"In the 2017 survey, it found that 28.7% of adults in England are obese and a further 35.6% are overweight, making a total of 64.3% who are either overweight or obese. 2 Of obese adults, around one in eight are morbidly obese (3.6% of all adults)"

Or almost two thirds. So the correlation of the virus and being overweight is uncertain at best.
