Comorbidities increase your risk or "serious COVID", just like being unvaccinated does. But that still doesn't satisfy anything. Comorbidities increase your risk, getting vaccinated decreases your risk substantially, so if you want to blame this "well only fat people get it", well sure. Most people are fat, therefore they should get the vaccine since you can do that in a very short period of time whereas weight loss takes a while and you may have other comorbidities that you can't actually control or change at all.
But aside from these asinine "fat positive" movements (which are very similar in pathology IMO to COVID deniers) nobody is out there advocating for people to ignore their weight and that drinking milkshakes just might not be bad for your heart. Next thing you know of course drinking milkshakes and eating burgers are ok. The government just wants to control what you eat!1!
It's the exact same kind of nonsense.
It may be difficult for some to accept, but we as individuals have essentially total control over our own health and COVID was no exception.
Essentially all serious COVID cases had multiple LIFESTYLE-casued comorbidities. The most prevalent: obesity.
