I live in Germany, I'm a participant in the Keto program in Cologne. I'm in keto more than 5 years now. Keto seems to work and inhibits cyst growth because in the last 3 years my EGFR stays the same altough It is too early to say that I'm saved because of keto, but we'll see. Time will tell. About ketocitra, I would like to try, it but it is very expensive. Greetings.
