The "may" in that statement (may be moving towards...) is doing a lot of heavy lifting, but I think it's true that if you want to predict future harmful manosphere beliefs then one of your best predictors is current actions aligned with the top of the funnel. That doesn't even necessarily mean those actions are bad, but the combination of all of them is suggestive of a certain reading diet.
Separately, are they all good? Testosterone has a lot of negative side effects, and I know I certainly wouldn't mind having about half as much. Jawlines and fiber have similar issues when focused on in the wrong way. Eating healthy, feeling good, and looking good are mostly orthogonal to those trendy behaviors. If they work for you then great, but there are other options too, and I don't think she's saying that you shouldn't want to eat healthy, feel good, and look good. Indeed, she explicitly says that fibermaxxing is bad because it replaces a healthy diet. She agrees with at least some of your goals and really only (potentially) disagrees with the implementation.
