It's time to take control of our health.

THE RIKER REGIMEN

[Published in August, 2023]
The Riker Regimen was written for one simple reason: to help people. It incorporates sensible lifestyle and dietary changes that address the “root causes” of their medical problems. In fact, most of these “chronic” diseases, are not chronic, and are completely reversible with sensible nutritional and lifestyle modifications. Such changes will also boost your immune system, which is very important for fighting cancer, and even preventing the development of numerous other cancers.
Beyond the cancer patient, I wanted to share this knowledge with the broader general population, as we witness the epidemic rates of childhood & adult obesity, type-2 diabetes, chronic inflammation, obesity-related cancer and death. It is all inter-related by the food choices that we make every day. This book provides you with a refreshing set of principles to easily understand what healthy human nutrition looks like. This book will encourage you to raise your own doubts and questions, and more importantly, search for the truth.
