Michael A. Klaper (July 19, 1947) is an American physician, vegan health educator and conference and event speaker, and an author of articles and books of vegan medical advice. He advocates rearing children on vegan diets throughhout their entire lifetimes, beginning with the vegan mother's pregnancy. Oncologist David Gorski claims that Klaper is "peddling highly dubious claims... pseudoscience and harmful surgical and cancer advice".
Early life and education
Klaper was born July 19, 1947 to Chicago South Side dentist, David T. Klaper, DDS, and Jean T. Klaper (formerly of Boca Raton, Florida). Klaper had a younger brother, Robert D. Klaper, who died in 1992 at the age of 49. By his own report, Klaper grew up on a dairy farm in Wisconsin.[better source needed] In 1972, Klaper graduated from the University of Illinois College of Medicine and served his medical internship in Canada at Vancouver General Hospital with the University of British Columbia. He also studied obstetrics at the University of California, San Francisco.
After graduating from medical school Klaper moved among a number of locations, practiced acute care medicine, and eventually became certified in urgent care medicine. He became a vegan in the early 1980s. He is a medical consultant for the North American Vegetarian Society and has spoken at their Vegetarian Summerfest in 2012 and 2018. Klaper has spoken at several other national and international vegan, vegetarian, and natural health conferences and events.
He served as director of a vegan health spa in Pompano Beach, Florida from the early 1990s and was featured on the 1991 PBS documentary Diet for a New America by John Robbins. In 1988, Klaper was a NASA nutrition adviser and on vegan diets for long term space colonists.
He also served on the Nutrition and Preventive Medicine Task Force of the American Medical Student Association (AMSA), where he is a member of its Board of Advisors. He cofounded with John Robbins the environmental organization EarthSave International and served as its Scientific Director. He is a Founding Director of the Institute for Nutrition Research and Education.
Klaper maintained a medical practice in Maui, Hawaii between 1995 and 2006, and practiced medicine in Whangarei, New Zealand between 2006 and 2009. In 2009, he relocated to Northern California, where as of 2011 he became staff physician and medical consultant at the nutritionally-based TrueNorth Health Center in Santa Rosa, where is now is on the Board of Directors of the TrueNorth Health Foundation. He is licensed to practice medicine in California and Hawaii and now is affiliated with the Santa Rosa Memorial Hospital.
His books include Vegan Nutrition: Pure and Simple and Pregnancy, Children, and the Vegan Diet. He has appeared in several films related to vegan diet and practice, including Eat This! (2005), Cowspiracy: The Sustainability Secret (2014), and What the Health (2017).
In August 1993 Klaper issued a medical certificate for the insurers of two movies that River Phoenix was working on at the time, Dark Blood and Interview With the Vampire. The certificate was signed by both Klaper and Phoenix and stated that Phoenix had never used "LSD, heroin, cocaine, alcohol in excess, or any other narcotic, depressant, stimulant or psychedelic. At the time Phoenix was deeply into the drug scene and died from a drug overdose two months later on October 31, 1993. Phoenix's death resulted in Dark Blood being scrapped, and his role in Interview with the Vampire being replaced by Christian Slater. A total $US5.7 million was paid out by the insurers of both movies as the result of Phoenix's death. Since Phoenix's death, insurance rates have increased significantly, medical certificates are no longer accepted, and actors are required to undergo more rigorous medical examination prior to being insured. 
According to oncologist David Gorski "Klaper subscribes to the all-too-common claim that a vegan diet is better than any other and supplements that claim with a belief that undergoing fasts, in which one consumes only water, is a major part of the path to health and wellness". He supports multiple pseudoscience medical claims such as acupuncture, chiropractic, naturopathy and border-line "germ theory denialism". Klaper also gives "highly dubious advice for cancer patients, even claiming that fasting can shrink malignant tumors. Klaper claims that fasts will clear up inflammation, eczema, arthritis and other issues. "The situation" according to Gorski, is "way more complicated than Dr. Klaper paints it". As a surgeon himself, Gorski is appalled that Klaper claims that fasting encourages "faster wound healing" a statement that Gorski calls "Bullshit!". Magician Penn Jillette reported on multiple podcasts that he has lost over 25 pounds on Klaper's water fast diet, Gorski responded that of course he will lose weight on a water-only diet. In Gorski's opinion as a medical doctor himself, "Jillette has fallen "hook, line, and sinker for a whole lot of dietary pseudoscience and promoting it on his show with a credulous interview with someone like Dr. Klaper". Gorski hopes that Jillette will eventually realize "that Dr. Klaper is peddling highly dubious claims (at best). Basically, the product Dr. Klaper is peddling in terms of science is a massive exaggeration based on dubious science, cherry picked cases, and bad evolutionary analogies. Worse, fasts, even when supervised by a physician, are potentially dangerous".
