As a selfish example, I have ARVC. I was diagnosed at 24 while training for my first marathon. Lifestyle treatments for my disease are to explicitly avoid exercise as it exacerbates the deterioration of my heart muscle. As I age, I expect to be at a much greater risk for the heart diseases that you would recommend "healthy living" for, as I will be categorically barred from one of the most important pillars of that, exercise.
I realize we're talking about the margins here, but as a margin, I would love more advancement in transplants.
How many eggs should I eat today to meet your personal definition of healthy living? And what do I do when it differs from someone else?
But if you're obese and eat junk food all day, or if you just sit around on your couch and never get any exercise, and then end up with (for example) heart disease, that is something that was likely preventable, and we have a pretty good idea why and what could have been done differently. I'm force to subsidize these people's health care to some extent, and I think that's unfair.
The whole autonomy thing is tricky. We live in a society where we "care" for each other in collective ways (taxes etc.). People who want to live in that society lose some autonomy as a part of the bargain. I don't think this means we should legally force people not to eat or drink certain things. But I do think that (for example) denying people liver transplants when they won't stop drinking excess amounts of alcohol is fine. They can have their autonomy, but then they have to live with the consequences of their choices.

In all seriousness, I think there's obvious medical definitions for unhealthy in regards to addictions, weight, etc. Let's not philosophize some libertarian defense of something that obviously restricts and constricts one's freedom -- the ability to move an inch without your joints buckling.
I can sympathise with you if you have suffered from anti-fat bullying and adopt defensive attitudes in reaction -- but what the hell am I reading.
How we choose to deal with watching people do things we think they shouldn't is a matter of character.
I will say that I try hard to listen to people's criticism with an open mind, but people who badger me when they know I have considered their position, well, we tend to spend progressively less time together the more it happens. There's a difference between sharing information and punishing people for not complying, and I see no reason to accept punishment for something I don't intend to change about myself. A second-best fix for the problem, but better for everyone concerned.
But yes, as adults we can determine for ourselves. But it's a poor character trait not to be responsible for how you feel.
