I suspect (and this isn't my idea) Keto works because it reduces the amount of dietary sugar and increases dietary fiber. It is the high sugar/low fiber diet that causes insulin resistance, metabolic dysfunction, microbiome issues, inflammation, etc. So keto may not be ideal, but is way better than the standard western diet.

I can tell you from my own experience of roughly 7 years with eating keto most of the time, that it’s my opinion it’s actually a low calorie diet in disguise. The higher fat and often slower digesting foods deliver satiety faster and better than other diets. When I am strict keto, I eat far less calories because my body is rarely telling me I am hungry and when I do eat…it’s telling me I am full in far less calories.

I thought the “typical” keto diet tends to be higher in meat, egg, seafood, and dairy-based product consumption than the western diet. Which would make it lower fiber, since that comes from plants.
