Not everyone optimizes for health. Plenty of people optimize for enjoyment or hedonism. That doesn't mean you can't also try to balance it out with healthy behavior to whatever extent you like. If you indulge in unhealthy habits in one way, why wouldn't you try to be healthier in other ways? Are you implying that just because someone drinks means they shouldn't bother to exercise because they'll never be "perfect" that way?

The timbre of your definition of "healthy life" sounds quite like rigid religious orthodoxy. Try "I don't get the pairing of being Catholic and having premarital sex. I know someone that goes to church every Sunday, but..."

See, in the case that she's trying to be a "good Catholic" or "healthy liver", it comes across as judgmental and priggish; in the case that she's not particularly concerned with what others think of her devotion, it comes across as dogmatic and parochial.

Anyway,"a healthy life" would be defined by many people as whatever mix of healthy activity and hedonistic enjoyment best suits the individual's well-being, including their psychological well-being. For instance, I have a friend who has cancer and is going through the torture of the damned with chemo. Yet above all, he's utterly miserable that he's not allowed to eat anything besides vegetables; the once-a-month Big Mac keeps him going and gives him something to look forward to.

I don't even like when doctors do this, but unless you're her doctor, you should refrain from casting judgment.
