NBC.com - The Biggest Loser

Dr. Robert Huizenga is considered one of the leading weight-loss experts in the country today. As an Associate Professor of Clinical Medicine at UCLA, Dr. Huizenga has a busy medical practice that studies obesity related issues.

Formerly, Dr. Huizenga was the Los Angeles Raiders doctor and NFL Physician Society President. Huizenga's experiences in football are chronicled in "You're OK, It's Just a Bruise - A Doctor's Sideline Secrets about Pro-Football's Most Outrageous Team." This controversial book became the basis for Oliver Stone's movie, "Any Given Sunday."

Before college, Dr. Huizenga excelled at math and chemistry, being named Valedictorian at Penfield High in New York. At the University of Michigan, Huizenga became an NCAA All-American wrestler while graduating with honors in zoology. After his undergraduate work was complete, Huizenga went on to become an all-star rugger at Harvard Medical School and specialized in immunology. Soon after, Huizenga was chosen to become Chief Medical Resident at Cedars Sinai Medical Center while also serving as a national medical correspondent for FOX-TV.

Dr. Huizenga has repeatedly been interviewed as a health expert on CBS, NBC, ABC, "Larry King Live," "Nightline" and many other news programs. He has also been called as a medical expert in multiple high profile legal cases, including the O.J. Simpson, anabolic steroid and Botox trials. He has had recurrent roles as writer, correspondent and advisor on numerous TV shows, including "LA Doctors," "Nurses," "Empty Nest" and, most recently, "The Biggest Loser."
