Looking at it from the other direction:
There are millions of Americans. Perhaps (I can't find the data) 30% of them fall into the the category of not overweight or obese. A study of about 148,000 patients found that only 22% of them fell into the category of not overweight or obese. Either the wording on the article was poor (distinct possibility) or the study found that the demographics of the hospitalized patients closely matched the demographics of Americans as if they were randomly picked off the street with no regard to weight.
Note that one of the limitations of the study was it could only consider patients where height and weight were listed. The data could be biased towards overweight or obese as the hospitals look for comorbidities. In other words, the hospital *might* list height and weight for overweight and obese patients more often than for patients who had a more "healthy" weight.

Let’s look at the demographics of those who have died from Covid as reported by the CDC. 78% were overweight or obese, with the odds 3X greater for obese people. Of those who died, they averaged 2.4 comorbidities. Those were primarily, heart disease, lung disease, diabetes and hypertension.
This is not a cross section of the general population. It is primarily overweight, unhealthy individuals. Spin that any way you want to make yourself feel better…
