There's a world of difference between an armchair internet-dietitian (no, I'm not implying you are one) and a registered dietitian that is the "director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital" (the author of the said article). It's not appeal to authority—we have to start somewhere. That doesn't mean the said page is 100% accurate.

No, I did not try Keto. Yes, I've done fasting before; and yes, it was beneficial. Personally, I'm disciplined with food; almost like a machine, I can happily maintain a healthy diet, without having to "negotiate with myself".

Please note, I'm not denying there are no benefits to Keto or fasting at all. I even recently listened to an episode on Keto on Huberman Lab Podcast to educate myself on it. I don't have personal experience of it, so I refrain to talk about it. Much less use data-points-of-one as a generalization.
