I have autoimmune and gluten sensitivity. Low fiber animal foods work for me, which are staples on low carb, too.

Everyone has their own tolerance, and bad ideas about nutrition push the envelope for someone, somewhere.

I essentially eat all the "wrong" ways: low fiber, salt to taste without fear, lots of animal fat and meat, zero hearthealthywholegrains, and low plant intake. But it works for me SO WELL may I serve as a reminder that your path might not "fit" but the only important part is that what you create fits YOU.
