You need fiber, friend. You. Need. Fiber.

Citation please. As far as I've read fibre does two things:

1. Anti-nutrient, when people eat terrible food fibre blunts it so it isn't as terrible by preventing some of the bad food absorption

2. Fibre is digested by the gut into short-chain fatty acids (SCA / BHB) which get absorbed through the gut, and has a boost to health in the area of absorption. However, in a ketogenic context the liver is making Ketones (BHB) all the time which gets deposited into the blood stream being available to the entire body including the gut... so this benefit is only seen in a carbohydrate metabolism, and not in keto.
