That isn't true, though. Neither the article nor the comment you're referring to say anything at all about weight loss. In fact, while most of the links in the top comment are guys who care somewhat about staying lean, Mike Israetel explicitly does not. His goal is just to get as big as humanly possible given his genetic constraints (but also while doing steroids). That is entirely legitimate when the topic of the study being discussed here is whether infrequent or more frequent lifting builds more muscle.
Your comment is non-sequitur. Perhaps weight loss is the majority fitness goal in industrialized nations of the world today, but it is still a legitimate and separate topic worth discussing for people who succeed or were never fat in the first place, but still aren't necessarily all that "fit," to think about what they can do to achieve some goal beyond just not being obese.
You'd think Hacker News of all places would understand this. For the majority of the world, simple tech literacy is a goal and presumably a whole lot of research and think pieces discuss that kind of thing, how to best promote it and what not. But everybody here is already tech literate. We want to be technically excellent, not literate. That is a different goal and the tools you need to get there are different.
The above resources are not promoting how to not be obese. They're promoting how to be athletically excellent.
The links provided themselves point to programs, the information is to sell courses.
If you take steroids your body will respond different then normal people. Using steroids and then to promote your programs that act like it's possible to achieve them without is dangerous.
The strain they will be able to put on their bodies are not the same as without. Even with steroids the strain is so high it can lead to serious life changing injuries like at least one the some of the linked have found out.
There many young people that have used steroids and have completely worn out joints.
The issue is that the links provided by first poster are advocating for such weight loss strategies. While they themselves are on steroids.
