There is no convincing evidence that "healthy eating" - whatever that is (eating "organic" vegetables?) - or a "healthy lifestyle," eg exercising daily or whatever - has any beneficial effect on your long-term medical future.
Those things might - or will - make you feel better, happier, and more functional, and nobody likes to carry 30 lbs. of unecessary lard around with them, looking like a muffin-top or worse. Nothing to do with health, though. And that is why "Lifestyle Medicine" is quackery which has been foisted on a credulous public.
One quote:
...it’s little wonder, then, that the results of every major randomized, controlled clinical trial of healthy eating and lifestyles to date have been ignored, downplayed, or explained away... or their benefits greatly overstated. As incredible as it seems, they have failed to demonstrate significant benefit in preventing chronic diseases of old age, like the big three diabetes, heart disease or cancers, or in living longer. Nor has any healthy eating intervention been credibly shown to give everyone a government-approved BMI.
Other than avoiding smoking and substance abuse, and taking our medicines, our fates are sadly not in our hands.
Carpe diem: every day could be your last.
