Otto Buchinger
Otto Buchinger (16 February 1878 at Darmstadt – 16 April 1966 at Überlingen) was a German physician, credited with being the first to systematically document the beneficial effects of fasting on a number of diseases. Buchinger studied medicine at the Ludwigs-University in Gießen, Germany. After his promotion he went to the German Navy as an army physician. In 1917 he was discharged due to illness, he suffered from tonsillitis that never completely healed and led to rheumatism in his joints. According to his daughter Maria Buchinger, on the advice of a physician colleague, the fasting doctor Gustav Riedlin , he tried fasting for the first time and after the 19th day of fasting, his condition started to improve rapidly. He then turned with full interest and enthusiasm to fasting as a therapy. In 1920 he founded his small fasting clinic in Witzenhausen in Germany. Later in 1935 he founded his first real sanatorium in Bad Pyrmont. In that year developed the fasting method and described it in his book, ""The Therapeutic Fasting Cure"", published in the same year. In 1953 he founded a new clinic at Überlingen on Lake Constance, together with his daughter Maria Buchinger and son-in -law Helmut Wilhelmi. His grandson Raimund Wilhelmi led the Buchinger Wilhelmi clinic in Überlingen with his wife and scientific director Francoise Wilhelmi de Toledo until their son Leonard Wilhelmi took over the leadership from February 2019. Buchinger fasting guidelines. The "Buchinger Fasting" regimen has a long tradition in Europe, with specific "Buchinger fasting guidelines" or "consensus guidelines" established in 2002, and updated in 2013. Medical studies that involve fasting often follow the Buchinger guidelines. The regimen involves colonal cleansing (purgation), and restricted intake (approximately 250–500 kcal/day). The term "multimodal" means that "physiotherapy, nutrition, mind-body methods, and psychotherapy as  well as physical activity are combined within a complex health education program."
