Karen Ellis Nutrition LLC

As a Certified Functional Medicine Practitioner and Holistic Certified Health Coach, I firmly believe that food is a potent form of medicine, and the key to profound health and wellness lies in mindful eating and understanding the principles of circadian biology.

My journey began with training at the Institute for Integrative Nutrition, where I delved into over a hundred dietary theories and explored various practical lifestyle coaching methods. My education then extended to The School of Applied Functional Medicine, where I honed my expertise in functional lab testing and DNA analysis. To deepen my understanding of the human body's inner workings, I dedicated myself to studying anatomy and physiology, functional physiology, blood chemistry interpretation, and circadian biology.

My passion revolves around empowering individuals to decipher the messages their bodies convey and take charge of their overall well-being.

Homemade Rigatoni with Bolognese Sauce

I was raised in a typical Italian-American household in New York. Some of my cherished childhood memories involve Sunday mornings when I eagerly tore into a loaf of freshly baked Italian bread and dunked it into the large simmering pot of tomato sauce that had been cooking on the stove for hours.

We would then gather around the table for a delightful dinner, passing around

a generous bowl of rigatoni.

In the Caputo household, we affectionately referred to it as "gravy."

Dieting pills

My lifelong passion for food was always overshadowed by the discomfort I experienced after eating. It wasn't until I faced a life-altering moment at the age of 35, when a diet pill triggered a stroke that required open-heart surgery, that I truly understood my life's purpose.

A year later, the sudden loss of my husband added to the complexities of my own health challenges. As a single mother of two young boys, prioritizing my well-being became my utmost concern. Little did I know, my life was on the verge of a profound transformation.

Diet Plan Concept - Selection of Green Food and Note Pad

Recognizing that I wasn't alone in experiencing adverse reactions to food, I was driven to find a solution. In 2007, after graduating from IIN (Institute for Integrative Nutrition), I enthusiastically embraced the RAW food movement. It was a true passion of mine, and I armed myself with essential tools like a blender, dehydrator, and spiralizer.

I was unstoppable, and I made sure to share my excitement with everyone around me.

However, after six months, I experienced a harsh reality check. Surprisingly, every conventional diet I tried seemed to exacerbate my symptoms rather than alleviate them.

Allergy food

Being an ardent foodie, the burden of my severe food sensitivities weighed heavily on me. The thought of living with such a restrictive diet seemed unbearable.

That's when Functional Medicine came into my life, along with extensive studies in physiology, anatomy, and biology. I threw myself into these studies, immersing myself completely, and my hunger for knowledge only grew stronger with time. I continued to pursue education and engage in extensive research.

Out of this journey, a lifelong passion was born!

Wellness and Happy Concept

Healing requires a profound connection with your body and the ability to heed its signals. Your body is perpetually striving for equilibrium, and achieving this balance involves nourishing it through proper nutrition, hydration, exposure to sunlight, and regular exercise.

Recognize the significance of "FEEDING" your body with the essential nutrients it craves for optimal well-being and vitality.
