What does Dr Filonov mean by vegetarian diet?

I've already contaced Filonov himself, but while i'm waiting for response, maybe there are people who already know the answer?

I remember he said in one of the live streams, that for people who want to do fractional dry fasting, the in between period after the first fast, one should be on the vegetarian diet. I wonder what that actually means for him? Fish is understandable, but some vegetarians also eat dairy products and eggs, so i feel a little puzzled. Maybe someone here knows what's up?
