I eat lc vegetables, but have been living VLCKD going on 6 years, and eat no more vegetables than before. Perhaps slightly less at certain times. My WOE has lowered BP and provided many other health benefits, and I would say I have not purposely added fiber in any other ways. However, the production of these 3-carbon molecules likely has other complementary mechanisms not related to fiber from grains and fruit, that was my point.
