If these work for you guys, don't take this as a criticism, and go for it!

But, just as an observation, that may be of interest to others, I'm unconvinced about the need for fibre, even on a LCHF diet. Protein and fat should digest pretty fully, and may not produce much stool. And crucifers like cauli and broc, especially raw, can be really bad for the thyroid, for a person with any weakness in that area.

If it's an occasional remedy, for slowing things down when there's a bug or something, that's different. But taken regularly may not be a good idea for many people.
