Buffett is famous for his fast-food heavy diet. Here's one article that quotes Bill Gates:
"Warren Buffett's close friend, billionaire and Microsoft co-founder Bill Gates, says Buffett mostly subsists on a diet of hamburgers, ice cream, and Coke. Celebrating 25 years of their friendship in 2016, Gates wrote in his blog, Gates Notes, "One thing that was surprising to learn about Warren is that he has basically stuck to eating what he liked when he was six years old." He recalled a time when Buffett stayed at his and his wife Melinda Gates' house, and opened a package of Oreo cookies for breakfast."
Anyway, I think the medical establishment is very much aware that genes matter more than diet, exercise, or anything else they can do. I had one extremely socially awkward PCP who, upon intake, was like "Asian? That's good, it means you'll live longer. Good genes." The problem is that such comments are both off-putting, potentially illegal, and completely unhelpful, because patients can't control their genes but can control their diet and exercise. There are a lot of statements that are true but useless, and discourse tends to select against them.
My first-hand experience and conventional scientific-consensus is that diet matters, not only for longevity of life but also for quality of life.
My Dad is addicted to sugary drinks and his feet are already showing signs of pre-diabetic nerve damage and he has lost lots of weight while his fraternal twin, who isn't addicted to sugary drinks has no such nerve problems.
The role of diet and genes can actually be tested on identical twins or studied that way and pretty sure any such study will show diet matters for quality of life and length of life.
The grandparent poster said something like "Conventional wisdom on Diet is wrong" is so vague to the point of almost being meaningless.
No one is disputing that genes matter but to draw a logical line from Buffet saying "hamburgers and oreo are not that bad" to "conventional wisdom on diet is wrong" is a mega-leap in logic which the grandparent poster should apply for the Olympics.
Mcdonalds food (in moderation) is not that unhealthy actually, but the grandparent poster is so vague I'm not sure maybe he is actually saying the same thing. My interpretation of his vague comment is that he is saying diet doesn't matter when it comes to health when there is overwhelming evidence of the perils of excess sugar and over-eating to health.
