Married since 1985, Gene and Joyce Daoust are two of America's leading experts in nutrition, fitness and weight loss. They are two of the original nutritionists who helped develop and test the 40-30-30 zone nutrition program. In 1992 the Daousts owned and operated "The BioSyn Human Performance Center" a cutting edge weight loss and sports nutrition clinic and the world's first 40-30-30 nutrition clinic. The Daousts have made the 40-30-30 zone nutrition program easy to understand and implement. They are co-authors of the small-press bestseller 40-30-30 Fat Burning Nutrition, and have created four Personalized Meal Planners as well as a Dessert Planner, which includes Joyce's famous Fat Burning Cheese Cake.

The Daousts are highly sought after motivational speakers and nutrition trainers. They are regularly seen on television shows around the country and have been featured in over 500 television and radio programs, magazines, newspapers and other publications. They are featured speakers and conduct programs for athletic teams and groups, professional trade associations, corporations and sales organizations, physicians, and health professionals.

The Daousts have helped hundreds of thousands of people lose weight, feel and perform better, and their ultimate goal is to help millions of people access their fat burning weight loss program.
