It simplifies the problem though, because for many, that approach has side-effects that seriously affect quality of life, like sleep, concentration, mood swings, depression etc.
Speaking of depression, I often get a similar vibe in those threads, where undoubtedly someone will jump in and say "all you have to do is lift heavy weights and change your diet a bit". It feels like they haven't experienced what other people have, so their advice sounds tone-deaf, a version of "let them eat cake".

If it works, it's great. Because obviously the "just change your life to be like me and hope for the best" approach doesn't work for most people, or they'd do it.
