Iirc it's like 75% hospitalized are overweight.... But 73% of Americans are overweight so it really isn't saying too much. I don't know if the recent CDC talked specifically about obesity, but that's nearly 40% of Americans too. Even if every American was a triathlon athlete, we'd still have had hundreds of thousands of deaths and millions of hospitalizations.
It's not good and it's a huge socioeconomic issue as well as a food "science" issue where garbage food is made as addictive as possible.
But all that said, epidemic obesity has many negative impacts on society, but not to the level a highly contagious and fairly deadly respiratory virus does. We've all seen and are still living with those impacts. Comparing the two strictly on death rate misses a rather large forest for a single tree.
