Then you're more trying out "the Ramadan diet" than anything else, which I think Putin raised a point against, saying that it's never been proven to benefit people more than any other sort of controlled dieting. Gaining control/perspective on caloric needs or trying out a new diet because it might grant a clearer mental state is commendable, but it's also not what Ramadan is.
Granted, I don't "have faith" in a God or gods, but I've absolutely seen the power that belief, right or wrong, can have. If you want to try out Ramadan, go all the way. visit your local mosque, attend the prayer sessions with an open mind. To paraphrase Biblical Jesus, Don't be a lukewarm beverage. So if you really want to do Ramadan, it's only respectful to do it right.
From your answer to Putin's first post: "I'm not fasting for any God, just out of respect for those who don't have food in the world, and as a health initiative, and to share in someone else’s experience."
Fasting out of "respect" seems to me foolish and patronizing at worst, and there are much better ways for you to follow a health initiative. The only reason left that I feel is cause enough for action then is to share in someone else's experience, and unless you choose to share completely, any insight you gain from the experience will be lacking.
