Fixing obesity involves education (not everyone knows why McDonalds is junk, or that too much of anything can be bad, meaning portion control), skills training/learning (cooking healthy food can be a big leap for someone who only microwaves a frozen meal), local environment (there are places with poor selection of fresh vegetables), lifestyle stuff beyond food (stress from working two jobs leads to eating badly, drinking, etc), and socioeconomic changes (not everyone can afford all of the above easily). That doesn't even involve things like getting you kids on board, fitness, etc.
And with all of that in place, significant weight loss is a long term effort spamming years for some people.
Getting a vaccine involves rolling up a sleeve then sitting for a bit in case of reactions. And maybe making an appointment.
Equating the two grossly overstates how hard it can be to deal with obesity vs getting a shot.
Of course not. We don’t understand how to prevent obesity. And losing weight—or keeping it off—involves more than visiting a Walgreens.
Also, if you’re obese, you’re suffering the effects of obesity all the time. If you’re unvaccinated, you are fine 99% of the time. If you stay home as much as possible, wear a mask outdoors and avoid large gatherings, you’re likely to continue being fine.

“The evidence base is limited in quantity and quality and insufficient to provide clear guidance“ [1].
The entire paper is about the “major evidence gaps.”
I have read many scientific, peer-reviewed papers on this subject. There is too much 'insufficient' data and too much correlation/causation issues. I am a hardware engineer, so am driven, delimited, and succeed or fail on the veracity of my data. I can generally depend on good data provided by suppliers and its efficacy because it is based on Physics. I have read may MS and PhD papers in botany and cellular biology, and a few CDC/NIH/FDA papers on the OT. I will conjecture that there are too many life scientists on these research teams and not enough physical scientists and engineers.
So it seems to be, in practice, a more complicated problem than reduction of smoking, which has been rather successful in many countries.
