My brother and his fiance both worked with Dr. F. My brother is a second year med student at U Pitt w/a MH from the School of Natural Healing.
He did the fast for research - presentation next year at U Pitt and, also, so that when he is practicing he is not a 'virgin'. Advising folks to fast when he had never done it himself. His weight went from 223 to 174 in the 21 days.
Dr. Fuhrman, Schulze, Christopher, Goldhamer, Lisle - we try and roll them all into one!
If you decide to ever go - True is the place. My brother has really enjoyed his stay - the staff is excellent.
