Some here say nutritional misinformation is one of the primary culprits, however, the reality is if you go tell someone "stop drinking soda, it's unhealthy", they will tell you "I don't care."
If people are not motivated to eat healthy, what are you supposed to do? Perhaps this goes back to educating your family on healthy eating, consequently if everyone were doing that, we'd see a trend of increased concern for healthy eating.
Occasionally interesting reading because I'm not a computer programmer or anything of the sort so I don't benefit from the tech job type of discussions or opportunities.
I've had a similar experience. I had symptoms for which I saw several doctors and eventually went to ER and was repeatedly just told by them and everybody else "it's just stress." Finally, I went to a specialist and they diagnosed my condition accurate and immediately. I don't even have any side-effects any more because now that I actually know what my condition is, I changed my diet accordingly. No drugs or anything, all I needed was someone to tell me what my condition is and that has improved my life immensely.
Speaking from a US perspective, a lot of people have a misconception of what "fitness" means in the first place. They think it means signing up for expensive and unnecessary gym programs and drinking twice your weight in protein.
In reality you can do it from anywhere, it's very simple, and there's no excuse besides physical disability or laziness. I work 12 hours everyday and sometimes 16, and yet ever since taking on this job where I sit in front of a computer for the entirety of that shift, I'm in better shape then ever. That's because I've developed a consistent routine of working out.
I don't have a schedule or use an app or anything, I just do push-ups when I get home and sometimes when I'm at work too. Instead of using the elevator, I take the stairs. It's just about doing something regularly. For bonus points, get good sleep and eat better.
Very personal anecdote on my part but I hate reading "not everyone has time to workout." How much time do you need to do 10 push ups if nothing else?
