losing weight too fast?

Hello. I am on a 40 day Water Fast right now (mostly for religious reasons) and I promised I wouldn't weigh myself because I don't want to focus too much on my weight but on day 5, I had my scale right in front of me and I couldn't resist.. so I weighed myself.. and I had already lost 11.1 pounds. Isn't that too much in just 5 days? (I am now at the beginning of day 7)
