Rachel S. Beller, M.S., R.D., is the nutrition expert for "The Biggest Loser," and her extensive
background in nutritional science makes her the perfect fit for the job. Beller’s philosophy isn’t just
about slimming down—it’s about the synergy of weight loss and preventative health.
Glamour Magazine put it best, describing Beller as "a genius at designing weight-loss programs that are
simple, yet at the same time tell you exactly what to eat and how to succeed...so you know you’re not
only going to drop a few dress sizes, but you’ll do it in a healthy—and, literally, life-affirming—way."
A Registered Dietitian with a master’s degree in nutritional science, Beller conducted extensive research
in the role of nutrition in cancer prevention at Cedars-Sinai Medical Center and the John Wayne Cancer
Institute. In order to translate clinical research into real-world results, she founded the Beller Nutritional
Institute (www.bellernutrition.com) in Beverly Hills, California. In addition to performing community
outreach, she is deeply committed to providing pro bono nutritional services to low income individuals
and non-profit groups. Her unique combination of science and straight-talk has made Beller the go-to
nutritionist for Hollywood celebrities, their families, international clients, and people from all walks of
life. Beller’s no-nonsense weight loss advice includes practical, easy-to-follow action plans, recipes and
illustrated "Buy This" shop guides.
Beller makes frequent media appearances, serving as a Nutrition Expert for the Oxygen Channel series
"Dance Your A** Off," "Dr. Drew’s Lifechangers" and Glamour Magazine, where she helps design the
"Body by Glamour" section. She has appeared on NBC’s "Today" show, "Good Morning America,"
"The Dr. Oz Show," "Extra" and the Style Network, and has been featured in Vogue Magazine,
WebMD, Fitness Magazine, Shape Magazine and many other national and international publications.
