Hey Nonstop and CT,
I did this last week with pretty good results. I did not follow it exactly, meaning I did not do the hot bath routine Friday night or any working out that day at all, and Saturday I just woke up and weighed myself. I had no real reason to look a certain way, just wanted to do this to expand my knowledge, and see what kind of results I would get. I dropped between 6 and 7 pounds total.
Monday thru Wednesday went well. Thursday not eating any solid food drained me, and I got a pretty decent headache around 3:30 that lasted the rest of the day and night. Friday, you can literally feel yourself starting to dry out, and eating again is amazing. Saturday I woke up feeling fantastic and my wife said was commenting saying it definitely worked, meaning she could see some more ab definition and three of the four qauds, haha. All in all, I would recommend doing it, and following it to the T if you want the full results. Now it's back to eating all the food and drinking all the water!!
