About The Book

Eat for Energy is the best nutritional wisdom that my team and I have uncovered, systematized, and refined over the last decade with thousands of our clients. In this book, I’ll do what I do with all my clients and in all my programs: cut through the pseudoscience to illuminate the real causes of fatigue and how you can rewire your body (and mitochondria) to produce youthful levels of energy once again.

Get your body out of defense mode and into a state of optimal performance to live at the peak of your energy, brain function, mood, and health.

Ari Whitten, functional health practitioner and creator of The Energy Blueprint program, takes you on a deep dive of our cellular energy centers, illuminating the clear nutritional methodologies and specific foods, supplements, and compounds you can use to:

A deep dive into the underlying cellular cause of chronic fatigue, burnout, and brain fog, with a framework for restoring cognitive function, alertness, and an abundance of energy.

Chronic fatigue, burnout, brain fog—however you want to call it, we as a society suffer from a constant feeling of being drained. From our families to ourselves to our work to our quality of life, a deficit of energy affects all that we hold dear.

There is a solution. But it doesn’t lie in our preconceived notions around caffeine intake, adrenal fatigue, or overhauling our lifestyle in a time-consuming and unrealistic way. And it isn’t a problem with our mind, competency, or motivation. Instead, the core underlying cause lies in our cells, more specifically, in our mitochondrial deficiency. When our cellular energy centers of mitochondria are suffering, our liver cells can’t detoxify us, our heart cells can’t replenish and invigorate us, and our gut cells can’t process our food.

The Energy Blueprint is a clear framework for reclaiming your energy, brainpower, and well-being created by Ari Whitten, CES, PES, and functional health practitioner. With simple, actionable tweaks to nutrition, sleep, and your daily habits, you will be able to get your mitochondria out of defense mode and into a state of optimal performance.

2-Times Best-Selling Author: Ari Whitten

Ari Whitten, CES, PES, is a functional health practitioner and the creator of the Energy Blueprint system for overcoming fatigue and increasing energy levels.

He is an energy and fatigue specialist who focuses on taking an evidence-based approach to energy enhancement. He is also a nutrition and lifestyle expert with a Bachelor of Science from San Diego State University in Kinesiology, and has recently completed coursework for his PhD in Clinical Psychology – an education which rounds out all aspects – nutrition, fitness, and psychology – of his approach to optimal health.

For the last five years, he’s been working with several world-renowned scientists and physicians to develop the most comprehensive evidence-based program in the world on the science of overcoming fatigue and increasing energy levels — The Energy Blueprint.

Many years ago, I was a healthy, active, energetic 24-year-old in a brief stint of living and working on a communal farm in Israel when I contracted the Epstein-Barr virus and came down with a severe case of mononucleosis (also known as “glandular fever” or “the kissing disease”). 

I had no idea that I would spend nearly a year trying to recover my health, well-being, and energy. I went from loving my full-throttle life to being incapable of getting out of bed. My throat became so sore, swollen, and filled with pus that I couldn’t eat anything but soup, and I rapidly lost more than 30 pounds of muscle mass. I lost all endurance and stamina to the point that small activities winded me and lost all my resilience such that I needed to lie in bed for 24 hours after even mild physical activity.

It was this moment that I realized: virtually no one in the medical establishment had really solved the human energy puzzle. This revelation changed the course of my life. After that point, I became utterly obsessed with making sense of the science of human energy.

For years, I wanted to do nothing more than spend all day, every day digging into the scientific literature and piecing together an actual understanding—a true scientific framework—of the real factors that regulate and control human energy levels, why people get fatigued, and, most importantly, how to fix it. Over the last decade, a considerable body of research has been conducted revealing the real cause of fatigue: mitochondrial dysfunction.

When our mitochondria become dysfunctional or, more accurately, when they turn down energy production (for reasons we’ll discuss in depth), then they cannot produce the energy that our cells need to do their jobs. Eat for Energy is designed to help you better understand the real science behind your fatigue; the role your mitochondria play in producing and enhancing your energy; how your body works to regulate your energy levels; and how you can use nutritional strategies, targeted foods, and powerful supplements and compounds to supercharge your mitochondria, get rid of your fatigue, and experience all-day energy, every day.

This book is required reading for anyone who wants a scientific roadmap out of lethargy and into full vitality. Ari Whitten has been my go-to reference for the true science of the human body for years—there’s no one I trust more. No matter what kind of eating approach you currently follow, this book will give you dozens of new nutrition strategies to fully optimize your energy. Enjoy!

This is the book I’ve been waiting for for years!  I’ve suffered for years with brain fog, lethargy, and used to overeat or over consume caffeine because I lacked adequate energy to keep up with my daily demands. This book has provided me with the blueprint to change that. Most nutrition books are either way too generalized, or way too in the weeds. This book beautifully fills a gap by providing people that don’t have PhDs or time to spend their days reading pubmed with real, cutting-edge science, highly valuable and actionable information and a framework to effectively master nourishing their body. Ari’s ability to synthesize, explain and engage the reader is exceptional. In a world that is overwhelming us with information,  this book distills down to the most up to date and useful scientific data and creates a fully actionable blueprint for people that want to look and feel 20 years younger. This will be my most gifted book to all of my family, friends and clients for years to come. As someone looking to optimize my health and longevity, as well as the way I look and the way that I feel, looking at nutrition through the lens of eating to support mitochondrial function is a game changer. Ari takes this topic to a level far beyond what has been done to this point and he does it in a way that is engaging for non science nerds. I get asked all the time what books I recommend on nutrition for health and longevity. This book is now at the top of that list.

With more than 50% of our nation’s children currently diagnosed with at least one chronic condition, and that number projected to increase to greater than 80% by 2025, the time to wake up and understand the root cause of childhood chronic disease is NOW. As an internationally-recognized holistic pediatrician, pediatric functional medicine expert and mom to 2 thriving kids, my mission in life is to help children everywhere thrive – physically, emotionally, and mentally. While Ari Whitten’s “Eat for Energy” is not targeted specifically for children, the tools that parents and practitioners will  learn through his decades of research and expertise will help children live to their optimal health and wellness potential. Why? Because the root cause of most chronic childhood disease lies in exactly what Ari so clearly describes in his book – mitochondrial dysfunction. Learning how to optimize your child’s mitochondrial function through Ari’s proven approach will lay the foundations to both prevent and reverse chronic disease no matter what stage of health your child is currently in. So whether it’s you, or your child, suffering from a chronic condition, or just not being your 100% absolutely best – then “Eat for Energy” is the place to start. “Eat for Energy gives parents the tools they need to take action today and raise their kids for a lifetime of physical and mental health.
