Penn Jillette

Las Vegas Entertainer and Magician

“Ray didn’t write a fad diet book. It’s about making a permanent lifestyle transformation. The magic is I still can eat anything I want. The trick is what I want has profoundly changed. He did the trick for me and saved my life, now let them help you.”

Cyan Banister

Angel Investor and Entrepreneur

“Working with Ray has given me a profoundly new understanding of how food impacts health and how what we eat is often dictated by social influences. I’m excited to be a part of his effort to push to this message out to a far bigger audience.”

David Sinclair, PhD, AO

Professor of Genetics, Harvard Medical School

“Ray is a scientific visionary.  The Healthspan Solution is a fact-based recipe book for longevity that belongs in every kitchen. Buy it.”

Rich Roll

Plant-Powered Ultra Athlete and Author

“Ray is a disrupter in the weight loss and plant-based healthspan community. While others have sought to demonstrate the adequacy of an exclusively plant-sourced diet, he teaches how it can be superior and mimics longevity research.”
