I don't have an education in this, so I can only tell you what I have concluded from all the reading I have done on curezone. My problem is mainly gallstones and because all the cleaning and improved diet I feel better, got rid off allergies.
Also there are different views on everything and since you are on Andreas forum, I would think he will suggest the cleaning. My message was only to hold you over till he has time to answer.
As far as hormones go you could also read Julia Chang's website http://www.sensiblehealth.com
BTW of hand I could not find any info on leptin.
