The question here is why dietary science is so unreliable? There are so many fads. Every year. Many of them with a base in a peer reviewed paper, but all conflicting with each other. And even reading this comments here: yes keto diet makes me sharp thinking, no actually keto gives 'brain fog', no it is glucose that gives 'brain fog'. It reads like a primary example of some random effects that people interpret to be c…

I don't think I'd inherently read all the conflicting reports from people as obviously mis-attributed noise. I don't think there's strong enough reason to expect everybody to response similarly to the same diets. Not only does everybody have unique genetics, environments, and histories, but how sure are we that all the people saying they do keto, for example, are doing the same thing? It's a giant complex mess, even…

anyone who I have ever known that did a water diet had the same results.

When I look at the garbage people buy in supermarkets and all the products that are peddled (in Europe btw, I understand US has a lot more "choice") no wonder people have no chance of winning. You go to a doctor being "markedly obese" with some additional health issue, they will not believe you'll ever get better. The fact that you could lose 20 or 40kg doesn't even enter their mind. Instead they give you blood-press…

Yeah - it is a good point about people reacting differently. My sister had Hashimoto and she did diet and now her hormones are OK without any supplementation. She did it a few years ago - and every doctor she consulted (here in Poland) did not believe that a diet can do that. But I trust her and she did a regular checkups of thyroid hormones and and something that showed the immune reaction to track the progress and…

What diet was that?

Because a) you can’t dissect and a human being and connect them to instrumentation for test and measurement like you would to a machine, and b) the meticulous wide scale testing available to drug companies costs billions, which no one would invest for dietary insights.

> just advising to stop eating

Generally, doctors do in fact do this, and it is incredibly ineffective, which is why they also treat the symptoms. The reasons it is ineffective are deep rooted in human psychology, support networks, and our conceptions of free will vs environmental effects. It is difficult to impossible for a person to simply "stop eating as much" for exactly the same reasons it is difficult for somebody to "just" exersize regularly or "just" look after their body or "just" study hard. We simply do not have as much control over our own fate as we like to think.

Autoimmune Protocol. Later relaxed by way of trial and error.

Can you cite some sources please? I've tasted some very sweet wild berries.

And I had some very sour apples so I think our anecdata cancel each other.

The existance of fruit that isn't sweet is not a counter example to the fact that sweet fruit exists at all

You can get more insight by discarding all studies that were performed in a timeframe of less than a year.

yea when it comes to diet, I think longevity studies can usually provide the most useful insights (although usually pretty generalized). You can do a diet for 5-10 years and not see the ill effects until that far in. Anyone who tries to sell you on a way of eating that has only been done en masse (relatively speaking) for a few years is a bit suspect.
