There is so much misleading "advice" in the above comment that it's not even worth refuting. I just want to warn to others lurking here to be cautious with it.

From the little I know (which is nothing!), going the "keto" route needs a specialist advice[1]. Diet is a charged topic; it would do us good to stay grounded. It's tempting to dole out uninformed advice on the internet. Please resist.

The point you raised at the end is more sensible: people might want to (responsibly and carefully!) try things and see what works for their bodies.

PS: In the past, I wrote here[2] the training routine that worked for me. It also has a link to a "retro" of my previous half-m.

...says he, and then links to a page of advice on the internet. The "Keto Diet Risks" section on that page is such an epic, "that it's not even worth refuting".

>> Fuzzy thinking and mood swings. "The brain needs sugar from healthy carbohydrates to function. Low-carb diets may cause confusion and irritability,"

This shows that whoever wrote this has never even tried proper keto. Because the brain does not need sugar (otherwise you would die after a few days of fasting), and fuzzy thinking is only for the first couple of days until your body adjusts and your brain gets enough fuel again.

It is in fact quite evil, because if someone starts keto or fasting and feels "confused and irritated" at first, they might just stop doing it out of fear of the unknown. Luckily in our modern society were are past such diseases as type-2 diabetes, right? So nobody should bother checking out something that might actually help with that.

But let me ask about your personal experience with keto or fasting. Did you try either? Did it work for you? I could link a hundred web posts about the benefits of keto, and another hundred about the dangers of it. In fact, anybody could google this for themselves, so I don't find this "I read this and that about something" contributing much to any discussion.

[Hi, I am not trying to be confrontational.]

> [...] and then links to a page of advice on the internet [...]

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.
