Hello! I’m Marlyn Diaz

“Let the beauty we love, be what we do.”  – Rumi

WHY I COACH – There is nothing I love doing more than helping others transform!

As a nutritionist & lifestyle educator based in Los Angeles, my holistic approach is simple, pure and effective. I lead people back to parts of themselves they have left behind or have yet to uncover when it comes to feeling slim, fit and healthy. I uncover the truth of what it takes for you to have radiant health and vibrant energy.  My intention is to inspire YOU through nourishing foods and vital nutrients, so you may live your BEST life ever! I have many years of training in integrative & functional medicine, have worked with top medical doctors, and  hold various degrees and certificates in health and nutrition. I’ve had the opportunity to help change countless lives. Yet, it’s not only my education that makes me experienced, it’s also my personal history. I’ve been in your shoes. I was unhealthy, overweight, undernourished, over-medicated and at the mercy of conservative medicine. But my life changed for the better, and so can yours. Here is my story:

Back in the 1970’s, while in high school  I was young, struggling with my weight and unhappy.  Physicians, fad diets and conventional medicine couldn’t “fix” me. Through my own searches I discovered books on health and wellness that approached, from a unique perspective, how one’s body actually works. I learned the truth about how different foods, vitamins & minerals, and lifestyle choices affect your health. One of my first high school term papers was on “food additives” – a concept that was well before its time. This was just the beginning of my journey.

A few years later I attended Drexel University and received a B.Sc. in Nutrition and Food Science. After college I discovered the power of a CLEAN, WHOLE-foods based diet and practiced upon myself until I fully understood how this new philosophy worked. I was amazed at the positive results.

As time passed, I continued my journey of knowledge.  Attending medical conferences, studying holistic nutrition, and learning about functional medicine and alternative health therapies has helped me to form more than a base level of knowledge. I’ve learned from some amazing and highly educated people – Physicians, Acupuncturists, Chiropractors, Energy Healers and other Holistic & Clinical Nutritionists, like myself. I’ve put into practice the knowledge that I have absorbed from so many studies – learning how to enhance health, balance nutrition and affect the aging process with the right foods, supplements and lifestyle choices.

In the past few years, I have completed my postgraduate work at Clayton College of Natural Health and Huntington College of Health Sciences, in addition to becoming a Certified Lifestyle Educator in Firstline Therapy, a therapeutic lifestyle change program.

It has been a long journey from being a teenage girl who desired information and longed for answers, to becoming the strong and healthy woman that I am today. This journey brought realization that natural and permanent change is within reach for all us, and that it can be done without chemical-laden diet drugs, weight loss surgery, and fad diets. I’ve learned that our bodies were designed to help us help ourselves. I’m so grateful that I have gained the knowledge and tools to help not only myself, but also others.

My story doesn’t differ too much from the stories of the clients I have helped and it’s probably not that much different than yours. Perhaps you’ll see some of yourself, or someone you know, in these words. I hope that my story gives you hope that change is just around the corner, and that there are people that have been there, that understand what you or someone you love is going through, and that there is help. Together we can create the changes needed to create a whole, clean, vital body and life for you.

After working together, here’s what some of my clients have shared with me…

With love, joy and radiant health,


Holistic Nutritionista
