Summary

Jay Feldman is a health coach, independent health researcher, and the host of The Energy Balance Podcast. With degrees in neuroscience and exercise physiology from the University of Miami, he chose not to pursue medical school after realizing conventional medicine often fails to address the root causes of common health issues. 

After exploring both conventional and alternative paradigms and experimenting with diets from vegetarian to keto, Jay discovered that cellular energy is the foundation of health. He now uses a bioenergetic approach to help people worldwide overcome symptoms of low energy, including chronic hunger, poor sleep, and stubborn weight gain.

Dr. Eric Westman is an Associate Professor of Medicine at Duke University. He is board-certified in Obesity Medicine and Internal Medicine, and founded the Duke Keto Medicine Clinic with Dr. William S. Yancy Jr. in 2006 after 8 years of clinical research regarding low-carbohydrate ketogenic diets.

A past president and master fellow of the Obesity Medicine Association and fellow of The Obesity Society, Dr. Westman co-authored The New Atkins for a New You, Cholesterol Clarity, and Keto Clarity, and co-founded Adapt Your Life, a low-carb education and product company.
