"Increased ACE2 expression in chronic obstructive pulmonary disease (COPD) patients who are overweight compared to those not-overweight was observed [3], indicating that SARS-CoV-2 is more likely to enter the human body in obese people as compared with non-obese people. " Not sure why you left out that the study was done on obese patients that also have COPD. You can also check the primary source [3]. "In summary, we have shown increased ACE2 expression in the bronchial epithelium of COPD patients who are overweight compared to those who are not overweight. This may provide increased opportunities for SARS-CoV-2 infection of the respiratory tract. These individuals may be at greater risk of developing severe COVID-19." Again, that's a hypothesis that makes completely sense, but from your study alone we do not know how much greater the risk is - 0.5% 5%, 50%?
