Thanks! My second pet theory, is that a LOT of the keto/paleo/vegan etc diets are popular because of undiagnosed autoimmune conditions.

Been reading through support groups for years now. A noticeable cohort of people find relief via diet. Sugar=bad, mostly. But even things like tomatoes sometimes need to go.

Or conversely that the standard America Diet is so horrible, that if you have any possibility of an autoimmune condition, then diet will push you over the cliff.

It’s not autoimmune. It’s inflammation. I have been eating LCHF for a decade now and it started with reading about eggs and cholesterol intake. Once I read about the drivers of serum cholesterol, and the interplay between glucose and insulin, it became pretty obvious that carbohydrates, in the quantities and concentrations that many people consume them, are genuinely poisonous.

Expand on drivers of serum cholesterol please...
