To be clear, I don't object to the message of the ketogenic diet being an effective solution for many problems, but I do object to presenting it as the one and only (or ideal) solution to everything. It's not clear if you intended for that. A literal reading of your top level comment conveys nothing of this sort, but if I give it a reading while pretending not to be autistic, I pick up on the implication that anyone who snores is fat. I think the responses you've gotten confirm this interpretation.
It's basically the difference between "Being fat causes snoring. Here's how to reduce body fat." vs "Being fat can cause snoring. If that happens to apply to you, here is what I believe to be the best solution."
I'm also not a fan of prescribing keto as a first resort because it's a huge lifestyle change for most people. The point of being healthy is to allow you to enjoy life to its fullest. If the lifestyle that the diet requires doesn't allow for that, then it's pointless.
As far as the mechanism of action of why carbohydrates are driving ectopic fat please read - The Carbohydrate-Insulin Model of Obesity - Beyond “Calories In, Calories Out” - 2018
The "access through your institution" button appears to be broken right now. Based on the abstract, it looks to be more about glycemic load than ketosis. So their findings likely also apply to the ketogenic diet, but I see no reason to believe it to be necessary.
Your not asking people to justify with references the "snoring is normal and healthy" vibe that is upvoted here. I think that speaks to the poor metabolic health we have come to accept in society
I don't think anyone is normalizing poor metabolic health. I'm certainly not. What I do question is the attribution of poor metabolic health to carbs alone, and all carbs on top of that. From what I know, just about everything in the body interacts with everything else, so while that means changing one thing (like reducing carb intake) can fix a lot of things, it is highly unlikely that the blame can be placed on any single thing. There are many ways to improve your health.
It also happens to fit my mental model of how things work, and I really don't have the time or energy to read something that just reconfirms my beliefs. I'm also not that interested in snoring, but I am interested in reading about nutrition. You also said it yourself: "[snoring is] not a major health concern (sleep apnea is)"
To be fair, your statement was very general
Fair. I did allude to all the other times you've brought this up. I should've been clearer.
