Bob Greene is the founder of the highly acclaimed Best Life Diet brand. Through his books, foods, fitness products and website, Greene has helped millions lose weight and live their own personal best life, using his gradual three-phase approach to eating and exercise.

Greene has two new books in the pipeline. In January, Greene will release his back-to-basics motivation book "The Life You Want: Get Motivated, Lose Weight, and Be Happy." Due out in April, is Greene's highly anticipated "20 Years Younger," an anti-aging guide co-written with celebrity dermatologist Dr. Harold Lancer. These are the two newest titles in a string of bestsellers authored by Greene, including his latest title "The Best Life Guide to Managing Diabetes and Pre-Diabetes," and "Best Life Diet," which was a mainstay on the New York Times Best Seller List for 31 weeks and named #1 Diet Book by Consumer Reports.

In response to the hugely popular Best Life seal of approval, Greene has launched his own line of Bestlife foods, beginning with a buttery spray, spreads and baking sticks available at stores nationwide. The Best Life seal of approval was created by Greene so consumers could more easily identify products that measure up to the rigorous Best Life Diet taste and nutrition standards. After years of requests from fans, Greene released his hugely popular title "Total Body Makeover" on DVD last winter. The DVD includes an eight-week progressive fitness program, nutrition plans and motivational techniques designed for all levels. He also released his first fitness products for the Nintendo Wii "EA Sports Active: Personal Trainer" and "EA Sports Active: More Workouts." Both gaming products feature Greene as a virtual personal trainer and carry the Best Life seal of approval.

Greene's website TheBestLife.com launched to become the fastest selling online program in the country based on subscription sales. The site offers various tools and resources including meal plans, shopping lists, recipes, videos, articles, news and tips from various health & fitness experts and an exceptionally active community for sharing and getting to know others.

Greene has worked with Oprah Winfrey for more than 15 years and is perhaps best known as her personal fitness guru. He has made dozens of appearances on "The Oprah Winfrey Show" and is a contributor to O the Oprah Magazine. He also writes health, nutrition and fitness articles for Oprah.com and his own website TheBestLife.com.

Greene is an exercise physiologist and certified personal trainer specializing in fitness, metabolism and weight loss. He holds a master's degree from the University of Arizona and is a member of the American College of Sports Medicine and the American Council on Exercise. For the past 27 years he has worked with clients and consulted on the design and management of fitness, spa and sports medicine programs.
