Keep in mind that, for thousands of years, we ate things because we were hungry, not necessarily because they tasted good. I've often told my kids "Everything that's a food became a food because someone was really hungry", something that comes up when they look at something like a lobster and ask why someone ate that. The yummy meals we've become accustomed to as an every day occurrence weren't a thing until basically the past 100 years (maybe say 80... post Great Depression/WWII). Now we have enough food to generally get to the reproductive phase of life without dying from a heart attack, and so we have to use those advanced brains of ours to be smarter.
Over the past few years I've been working more on modifying my diet to be more healthy, plus better exercising, and I cut out the alcohol altogether. Yeah, I'm eating an egg scramble with brussel sprouts, kale, and lentils this morning, but I've gotten used to those as well as drinking my coffee black as opposed to super sugary. When I first made some of those changes it took me a few weeks to get used to it. Once I did, I didn't miss it at all. My current shift is significantly reducing red meat from my diet.
The post above of considering meals as either fuel (gives your body what it needs) or food (more of a treat) I think is a good way of thinking about it.
I'm in the best shape of my life and I feel better than ever (although still some areas to improve upon). I don't necessarily care about living forever, but the goal is to live well as long as possible, unlike some of my relatives who lived a long time and have been physically unable to do much of anything post-retirement. Also, I want to hopefully prevent dementia from occurring - something that has also plagued my blood line.
