Barry Sears, Ph.D. (born June 6, 1947, Long Beach, California) is an American biochemist and best-selling author, best-known for creating and promoting the Zone diet, a fad diet which is not well supported by medical evidence.
As stated in several of his books, the Zone diet was born of his desire to avoid an early death from a premature heart attack, a fate of which all other men in his family had been early victims. In more recent years, Sears has popularized the use of high-dose Omega-3 fatty acids and polyphenols to further reduce inflammation. He recently revealed in an interview that he began studying lipids primarily because of their complexity.
He released his first book in 1995, The Zone: A Dietary Road Map. It went on to sell over 2 million hardback copies and was a No. 1 New York Times bestseller. Since then he has frequently appeared in the United States media, including CNN, Forbes and Good Morning America.
