Dr. Michael Fredric Roizen (born January 7, 1946) is an American anesthesiologist and internist, an award-winning author and the chief wellness officer at the Cleveland Clinic. He completed a tour of duty in the Public Health Service and has 165 peer reviewed publications and 100 medical chapters, 14 US patents, started six companies, served on Food and Drug Administration (FDA) advisory committees for 16 years, and chaired an FDA advisory committee. He also co-invented a drug, Methylnaltrexone (MTNX, trade name Relistor), and took it through phase 2 trials. In May 2008 Methylnaltrexone received FDA approval for marketing in the United States (he has sold his rights to that drug).
He became famous for developing the Real Age concept and has authored or coauthored five number one New York Times best sellers, including Real Age and four in the YOU series—those with Dr. Mehmet Oz.
He has been praised for encouraging Americans to exercise and live healthier lives - and has been an outspoken critic of politicians who use health funds for other purposes - particularly for taking tobacco settlement money and using it for unintended purposes. Besides advocating for a healthier lifestyle today, Roizen has speculated that by 2023 one of the 14 areas of aging might have a breakthrough that will allow us to live until 160 with the same quality of life as at age 45. This speculation has been met with both criticism as well as agreement.
Roizen has also been criticized for what has been called his wild exaggerations about the potential payoffs of exercise and healthy eating.
He received a Bachelor of Arts degree from Williams College in 1967 with a double major in Chemistry and Economics. Subsequently, he attended the University of California, San Francisco, School of Medicine. His residency was at Harvard's Beth Israel Deaconess Medical Center. After 9 years on the faculty at the University of California, San Francisco, he was the chair of the Department of Anesthesia and Critical Care and Pain Management at the University of Chicago for 16 years. He then became dean of the School of Medicine and vice president for Biomedical Sciences at SUNY Upstate.
He co-founded RealAge, a service providing personal health tools to consumers, and is chairman of the RealAge Scientific Advisory Board. He became the Cleveland Clinic’s chief wellness officer and chairman of the Clinic’s Division of Anesthesiology, Critical Care Medicine, and Comprehensive Pain Management in 2004 and was named chief wellness officer and chair of the Wellness Institute in 2007.
Dr. Roizen still practices anesthesiology and internal medicine, using the RealAge metric to motivate his patients. He has personally delivered medical care to 8 Nobel Prize winners, more than 709 ex-smokers, and over 100 Fortune 500 CEOs and CFOs. He chaired the United Way Fund Raising effort at the Cleveland Clinic in 2006 (it achieved record results, including over a 15% increase in donations to become one of the top 3 healthcare organizations in United Way Donations), and has served on the boards of five non-profit foundations. Roizen serves on the Advisory Board of HealthCorps. He served as President of the Society of Cardiovascular Anesthesiologists in 1997-8, and has won over 75 trophies in class A squash competition. He has been in the Best Doctors in America and then America’s Top Doctors (the successor book) since 1989.
Roizen and his wife, Nancy—a developmental pediatrician—live in Cleveland, Ohio. The Roizens have two children: Jenny, a Williams graduate with a PhD in Chemistry from the California Institute of Technology, is a former postdoc at Stanford and is currently an assistant professor in Chemistry at Duke University, and Jeffrey, MD/PhD, received his double doctorates from Washington University in 2008, and completed a residency in Pediatrics and fellowship in Endocrinology and Diabetes at Philadelphia’s Children’s Hospital, where he is now an instructor.

He and Dr. Oz coauthor a daily newspaper column syndicated through over 65 newspapers in the United States and Canada.
The idea for RealAge started in 1985 when Roizen convinced a 47-year-old entrepreneur to take his blood-pressure medication by explaining he was living with the body of a 52-year-old by not doing so. The entrepreneur paid for Roizen to assemble a five-person research team and come up with similar numbers for other controllable factors that affect length and/or quality of life.
The first RealAge test debuted online in 1998.
Michael Roizen became the Cleveland Clinic’s chief wellness officer in mid-2007. The position was new for the clinic and was notable, as it made Roizen one of the top 12 executives within the health system. He is also a professor of medicine at the Cleveland Clinic Lerner College of Medicine.
Among his initiatives are starting a farmer's market near the clinic’s main campus, mentoring children in the public schools, and starting smoking cessation and weight-loss programs. He has also encouraged an expansive walking-focused health program that includes a walking program co-sponsored by Google.
He’s also used his position at the Cleveland Clinic as a bully pulpit from which to advocate for what he sees as more effective uses of tobacco settlement funds. He criticized the Ohio government – and specifically denounced Gov. Ted Strickland as "stupid"  when the state decided to take control of $230 million that had been designated for anti-tobacco programs.
