I don't think they're worthless by any means, good ones are great. However, you need to carefully vet them rather than trusting their advice by default to the degree you might (or should be able) to trust a doctor or the like.
If you decide you want to work out and eat right, take responsibility for it and truly make the personal choice. Or buy a couple of self-help books to learn some techniques. E.g. The Power of Habit. It'll be orders of magnitude cheaper.

For the people who absolutely can't afford it, there's a lot of good information for free online. My point is that for many of us, we treat professional help as a luxury or explain it away rather than embrace it as a necessity.
The real wealth in life is your health.
There's also tons of it that's downright horrible or outright dangerous. The simple truth is that most professional help in the US is out of reach of most people unless they're willing to take on a significant debt the their salary doesn't support. It's not as clear cut always as "health is most important" -- it's not even clear how much any given procedure will cost two different people with the same insurance for the exact same process.
>If your doctor told you the only way for you to see another year was to get in shape and eat right, how would you prioritize then? Would you still go to the movies? Go out for drinks and food?
Maybe not a good example, as if my doctor told me the only way to see another year was to basically cut out a few pleasures in life, I'd just bite the bullet on this one, and I imagine quite a few others would also. This isn't suicide ideation or anything, it's more just a value judgement; how great will my life be during that year? Right now, without the mental stress of imminent death in my mind, an enfeebled life or one that just racks up a huge bill for those legally closest to me seems pointless.
Ultimately I agree with you that we can make time for ourselves -- an hour walking is better than no time walking, and if you can convert that into 15 minutes of jogging, even better. It's the same time we spend watching our shows on Sunday, and I think we can at least do that for ourselves.
But as someone who loves to cook, hates takeout, etc, there are days when even I just don't have the usual energy to go through and prepare a proper meal or to put the hour into my regularly scheduled run: 12+ hour days do that to you.
Only that the good information is often vague and mixed in with horrific information. Or is grand information for someone in decent shape but horrible advice for you in your health condition.
I'll add that there is more to it than simply getting the right advice. There is basic equipment. I'm not talking about anything fancy: For example, I wear an odd bra size. I'm thin and have large breasts. I have not had surgery to enlarge them. I have to buy at specialty stores here (Norway), and could not find my size in stores in the states (indiana). A regular bra is expensive.
I've never had a sports bra that fits. I often can't find them large enough and the ones that come close and actually offer some support are expensive - plus I have to order them. These are, in general, $60-$100 each. I have a similar issue with bathing suits, so even if I had free access to a pool, I couldn't actually use it.
Shoes have been an issue in the past as well. Buying the cheapest shoes possible, I was wearing through shoes withing 2-3 months and trying to keep them for 4-6 months. This is without exercise putting additional stress on the shoes.
The other issue I found with such things while being poor was hunger. Even if I walked, had an active job, and/or wasn't too strenuous with motion, increased hunger was an issue. $25/week for food doesn't go far. Especially not in a house with bad heat (60 degrees if it wasn't too cold out). More activity meant that I was miserable more simply due to hunger.
> Also, if you're struggling with getting fit, GET A PERSONAL TRAINER AND NUTRITIONIST.
There are tonnes of people out there who are just scraping by, who have to work two exhausting jobs, who have to spend all of their free time looking after kids, etc., who can't afford the gym, let alone a personal trainer and nutritionist.
If you have the time and money to do those things, then they are very good ideas. But they are out of reach for an awful lot of people, so perhaps try not to view the people who don't do this stuff as people who are making insane choices.
