This is certainly not the norm. Although having to cook/buy/think about food is annoying, the overwhelming majority of people I know love eating. The rest are mainly apathetic (target market for Soylent and similar products), I don't think anyone I know actively hates eating, with the caveat that several have to exclude certain foods for various reasons.
Change hates -> drags and it'd still be the same meaning just less strong. I know many people who hate meal prep but that's totally separate from the actual act of eating which is absolutely not seen as a 'drag' by most people.
It's a basic human drive so if you've grown up with a negative experience that you've generalised unknowingly to something that should be pleasurable, you should know that, since recognising it will hopefully lead to a fix. The reason to care is because you have to eat, so it's preferable to enjoy it rather than not.
You’ve misunderstood the degree to which I find eating to be inconvenient. It is merely that: at times inconvenient. I have a good appetite and am more likely to gain excess weight as opposed to losing weight due to not being motivated to eat.
