Not sure I like this. Studies show that obesity raises your death rate 300%. Yet it does not ask that. Vitamin deficient people die 200% more often. Yet it does not ask that question. These two were the greatest death causing commodities according to the largest study in America on the issue.
Yes. There is plenty of clinical evidence that obesity is far and away the number one risk factor for an adverse outcome from COVID infection.
One study based on a massive U.K. NHS database indicated that, for someone below the age of 50 and not overweight (i.e., a BMI below 25), the risk of dying from COVID was essentially too low to measure. Notably, the presence of any other co-morbidity was irrelevant. The only variable that mattered was weight.
