If obesity were preventable by two free shots, and the ICUs were flooded by an obesity epidemic, I'd consider it acceptable to take that into consideration during triage, too.
Eating less isn't that simple, there's a bloody powerful biological imperative to eat, and modern diets, plus industrialized societies hijack a lot of the negative feedback loops that are supposed to prevent us from overeating... Also, crappy, addictive junk food - or empty carbs - tend to be the most affordable option at the grocery.
Vaccination is two free ten-minute appointments at any doctor's office, UCU, or grocery.
Comparing the two the way you do severely undersells why obesity is such a difficult problem to solve. If it could be solved by two free shots, it wouldn't be a difficult problem to solve.
For some people eating less is easier than getting vaccines. I know people who have panic attacks over the thought (they had to be put under to get vaccinated).
Also, lots of people come from communities that were experimented on by big pharma which explains rate differences amongst races.

This can't be the reason for why >40% of the eligible population isn't vaccinated.

Even if this does explain lower vaccination rates among Hispanics and African Americans (Who, by the way, have much worse outcomes if they catch COVID), it doesn't explain why white people are also not getting vaccinated. It also doesn't explain why most minorities who have not gotten vaccinated give a reason of "I want to wait and see" [1], and why most white people who have not gotten vaccinated give a reason of "I've already made up my mind, definitely not getting vaccinated."
They don't trust doctors recommendations for vaccination, but apparently trust doctors recommendations for every other aspect of getting treated for COVID...
The point is that what other people not willing to do, or being afraid to do, can be difficult for them, even if irrational.
I personally can't think of easier thing than losing weight when you know you will die younger and know the present life has worse quality of life as well.
Of course the obesity problem has their own anti vaxxer movement where people claim obesity and health problems are not related, that it's beautiful etc.
