Honestly, I have no idea if it's helping me. I've always been pretty healthy, so there weren't any acute problems to clear up.

I just layer it on top of my daily intermittent fast, as well as not drinking water during the day. I still have coffee in the morning, which breaks the dry fast. Most days, I'm probably going about 14 hours without water and 16 without food.

A colleague of mine told me about it and I thought he was nuts. Then, a while later I saw a video about it from Eric Berg (I think) that went into the science and research. I found that convincing enough to give it a shot and it just became part of my habits.

My colleague mentioned that a NASA scientist has written a lot about this, so that might be something to look into.
