Meet Dr. Layman

World-Class Metabolism Expert Who Has Conducted Over 120 Research Studies

Extraordinary Accomplishments. 

Proven Results.  

Dr. Donald K. Layman is professor Emeritus in the Department of Food Science and Human Nutrition at the University of Illinois at Urbana-Champaign.

 

He is internationally recognized for his research about dietary protein and amino acids. He has extensive research focused on muscle development and in studies of metabolic regulation for obesity, diabetes and cardiovascular disease.

 

He is widely sought as a keynote speaker at professional meetings, medical conferences, and as a consultant to major food companies.

 

  • Over 120-peer reviewed research publications
  • 30 years as Professor of Nutrition at the University of Illinois at Urbana-Champaign
  • Head of the Department of Foods and Nutrition
  • Associate Dean of the College of Agriculture
  • Doctorate degree in nutrition and biochemistry
  • Master’s degree in biochemistry

Dr. Layman’s research led to a remarkable new discovery and an exciting new root-cause approach to lasting weight loss.  And all begins with your metabolism.   

AWARD-WINNING RESEARCH SCIENTIST

The discoveries of Dr. Layman were recognized with awards from the National Institute of Health and American Society of Nutrition among others. His novel research produced well over 120 publications in the most respected nutrition publications in the world.

 WORLD-CLASS NUTRITIONIST & BIOCHEMIST

Dr. Layman has devoted his life to advancing our knowledge and understanding of how our metabolism works.  He has conducted clinical trials for nearly two decades and advised in many more, leading to an entirely new understanding about how to optimize our macronutrient balance and metabolism. 

ADVISOR TO CORPORATIONS, GOVERNMENT, MILITARY AND … YOU!

Advising NASA, branches of the military, non-profits and large corporations, Dr. Layman’s research has been widely used to shape the very latest nutrition guidelines. And now his decades of breakthrough scientific discoveries are being made available to you, as your very own nutrition advisor.
