I am in my late 60's, very healthy, wanted to try this to see if it would reset my metabolism. I've fasted for 40 years, so used to it in all forms.
The actual fast was easy; however, there are a few things that you should be aware of.
First, it is extremely expensive, and in my opinion, definitely not worth what you get in any way, shape or form.
Second, I started without any physical problems; healthy in mind and body. On day two I started getting joint aches and pains, by day four I felt like I had arthritis throughout my body, and by day five I got heart palpitations!
Loads of support BEFORE and absolutely nothing afterwards from them.
I'm a retired naturopath, so immediately loaded up on nutrients and some herbs. It took me three days to get back to no problems, but the experience left me very upset as I highly value my health.
Be aware. Check other reviews as you will only see good ones on their site! I would recommend going on Amazon and checking out (by their reviews) some of the excellent fasting books out there instead of wasting your time, money and health on this!
Bottom Line: No, I would not recommend this to a friend
