Individuals on a pure carnivore or keto diet who consume meat may develop a more sensitive palate for umami flavors and a craving for umami-like foods.

“people that for instance eat a pure carnivore type diet or a keto diet where they are ingesting a lot of meat, so therefore are sensing a lot of umami flavors. And I realized not everyone who's keto eats meat, but those who do that will develop a more sensitive palate and likely there are some data, although early data, craving for umami-like foods.”
