Does Intermittent Fasting work because you consume less calories or because of ketosis?

I am doing omad and am trying to keep my daily calories under 1200. I lost 3 pound in two weeks. Is the loss due to CICO or because there is ketosis. via /r/intermittentfasting https://ift.tt/kjTSJBN https://ift.tt/HmCUWw6
