I've been fighting this battle with my H for years. After that day which shall not be uttered in this forum, he lost a lot of weight due to losing his appetite. But he has slowly put it back on, and then some. His issue isn't so much the weight, as it is where that weight is... all in the middle.
About a year and a half ago, I talked him into switching to my doctor (his was a joke), who has a concierge practice, so he really takes time with his patients, and spends a lot of time translating all those blood test results he orders 1-2x/year from the Cleveland Heart Clinic. He looks at so much more than just cholesterol and A1C numbers. Our doctor basically plants seeds from early on, that we would age better with certain lifestyle choices and taking certain supplements. H is good about the supplements (because his numbers started improving when he took them), but has basically turned into a sloth when it comes to exercise. He used to play golf and ride his bicycle on a regular basis, but hasn't really since our move four years ago. Honestly, I'm kind of happy he doesn't ride around here because we don't have the dedicated bike paths (not lanes... paths) like we did back in IL.
About a year and a half ago, when I switched trainers to a male, I started working on H to give him a try. H was doing nothing to strength train, and mobility and being strong are just so incredibly important to aging well. Every few months I'd suggest he give the trainer a try, and he'd say maybe, then never follow through. In the meantime, I've watched his mobility decrease, and I know the further it goes down, the harder it is to get it back. We are in our early 60s, have a new grand baby and want to be actively involved in his life. I think that's what finally got H's needle moving to the right side. Two weeks ago, he finally agreed to start working with my trainer. I think he was dumbfounded when he realized in the first session just how weak he was. He only made it about half way through the three sets our trainer walks me through. He hit a wall, and could do no more. And I know the trainer wasn't pushing him that hard. Each session he's had with him since, has been a tiny bit easier, and they've gotten through more, so hopefully he'll see the upward trajectory as a motivator.
I work with the strength trainer twice a week, and do Pilates twice a week. While I could be stronger, I'm not doing too bad for someone my age. I see a lot of friends my age that don't even get out for regular walks, much less any workout. And maybe this a co-dependent way of thinking, but I don't want to be a burden on people if it's due to my own self-neglect. Do I eat perfectly? No (just popped some M&Ms in my mouth before I sat down), but I do pretty good - limit processed food greatly.
My doc is into genomics and wants me to get my genes tested. I know my hyperlipidemia is genetic - nothing I can do about that. As well as my blood pressure. A1C is manageable, but again, all genetic. Lots of heart disease at a young age in my family. Just my two cents, but I think that, to a certain extent, people who don't make some sort of effort to make changes as they age, are selfish. They aren't thinking about who is going to have to take care of them when they become more and more immobile. Again, accidents happen, genetics happen, but there are many things we can control.
Regarding doctors, I've found the ones who take good care of themselves are better about talking to their patients about healthy lifestyle choices, even when the patient continues to ignore them. Our doctor works out, eats healthy, maintains his weight and takes care of himself via annual routine screenings. Come to think of it, my concierge doctor back in IL also did the same. Maybe the doctors who aren't pressured by a practice or insurance to rush through visits are the ones who take the time to discuss lifestyle choices, and why they are important. Of course, people who spend the money for a concierge doc are more likely to heed their advice, because otherwise, why would they spend the extra money? I remember interviewing one doctor when we moved out here, but he was really obese, and I thought, "How is he going to encourage me and motivate me to make healthy lifestyle choices, when he isn't doing it himself?" So I passed on his practice.
So I think whether or not a physician spends time educating their patients, a lot depends on whether they take care of themselves. It's kind of hard to keep offering suggestions to your patients if it constantly reminds you of what you're not doing for yourself. Again, just my opinion and experience with myself.
