Hi Dr. Chip, unfortunately, I cannot access the modules without signing up for the program. It's designed by Kimberly Synder, best selling author of the book The Beauty Detox. She believes in lots of veggies, fruit, and is herself vegan, though she does not operate by pushing people to the place she has progress to. Rather, she believes that small health improvements over time are better than none or a radical 100% revamp, and also add up to better health.
Her primary 'concern' is with proper digestion. As you know, more studies are coming out regarding the importance of a properly flora balance and healthy gut for improved immunity, emotional health (Serotonin) digestion, etc.
Like I said, she doesn't advocate any pills or concoctions, except for the possibility of a probiotic pill, taken once a day (there are no other herbal, vitamin, etc., supplements). I, myself, am a researcher but can't really find information about this issue for kindeys. I know from experience that detoxs can be harsh on the system and bring on a lot of unpleasant symptoms.
Kimberly's type of detox (I'm don't even know if she uses this word, maybe not, I forget) does not seem like the kind she is advocating ie., just jump into all liquids, potions, no caffeine, sugar, or processed foods from the get go.
There's a 1/2 hr or more video intro to this program that I saw and I did not detect anything there that made me feel uncomfortable about following such a program.
However, I am completely new to having CKD, hypertension, obesity and anemia. I know the kidneys filtrate out a lot of toxins, but I don't know if a cleanse like this (i.e., gentle, clean foods, self scheduled based on how you are feelings or how fast you want to see results) would or could affect the Kidneys. Maybe it will help them to get rid of the gook; maybe it would damage them. I just don't have a clue. I know I would not, however, do a cleanse that involved supplements -- again, as long as a probiotic is ok for me -- of any kind, strange, exotic foods and so on. I know at least that much! :-)
Hope this helps.
