Have a friend like this. He's 50. Just got diagnosed with haemorrhoids. And that's no joke. He can't run or do any weights whatsoever. He can have an operation to try to fix it but the success rate isn't great. He lived a life of being in good shape through exercise and limiting intake, and he took his multivitamins. But his actual diet was not good. Very very few vegetables and not much fruit. He's not gonna die of a heart attack, but I wouldn't rule out the big C (particularly bowel). I have not tricked myself into liking healthy food. But even if I have, isn't that a good thing? Like using some mental conditioning to enjoy running or the buzz you get from solving puzzles for a living. A life long bad diet catches up with you. I love the texture and taste of a salad that has crunchy vegetables finely chopped, grilled low fat halloumi, roasted hazelnuts, pomegranate or other fruit and some dressing I concocted. It's zero effort to love it. Did I "learn to like it" or do people learn to stomach deep fried foods? Why one and not the other?
