Net Nutritionist

About Gay

Headshot netnutritionistGay Riley a functional medicine nutritionist based in the Dallas, Texas and works with patients worldwide.  She has practiced  personalized holistic nutrition for 33 years and has been referred to as a  “Master” of nutritional medicine. She  focuses on helping people find the source of symptoms and correcting it with food , lifestyle, and individualized supplementation. Gay’s patients tell her they are tired of taking medications to treat symptoms that lead to side effects that only make them feel worse. ” The body has the ability to heal itself and dis-ease is directly connected to what we eat and how we live.  Food and lifestyle habits are the fertilizers for the gastrointestinal garden.   If the soil is unhealthy this creates imbalance for the entire body leading to suboptimal health, fatigue, insomnia, adrenal stress, brain fog, digestive problems, chronic disease, weight difficulties, thyroid disruption, autoimmune disease, depression, and anxiety, learning disabilities and more.  We all have different nutritional needs.  One persons nutritional medicine might be another persons nutritional poison so it is important to determine what foods heal .”

Gay’s personal health challenges have guided her to search for the answers to her own self-healing. “I suffered with digestive issues, low energy, and pain for a long time.  Finding the source of the problems allowed me to regain my life naturally without medication.” Gay’s father passed away prematurely at 48 which caused her to become interested in lifestyle, genetics, and holistic nutrition.

Gay’s first nutrition job was working at Scottish Rite children’s hospital developing test diets for children with rare neurological, metabolic, and orthopedic conditions.  This set the ground work for understanding how nutrition could improve the brain and body.  In 1987 Gay started working in weight management, a problem she had personally struggled with all her life. For 14 years, she worked in weight management, and education.  During that time she was also senior consulting dietitian with Apex fitness group and was involved in the Bodybugg Armband technology development also consulting with 24 hour fitness. She worked with competitive body builders, elite and professional athletes, dancers, and sports teams. She believes it is important to collaborate with other healthcare professionals and healers.

We are integrative whole beings, mind, body and spirit.
Not just individual body parts.


Gay uses a broad spectrum of nutritional testing such as Spectracell micronutrient testing, IgG, IgE, and IgA food allergy and chemical sensitivity testing, neurotransmitter testing,  toxic elements and mold, GI stool analysis testing to measure gut health and digestive function, breath testing for small intestinal bowel overgrowth (SIBO), metabolic testing, fatty acid deficiencies, and adrenal stress to develop a specific plan of action for each individual. Many of the tests are covered by insurance with a copay. She also offers individualized nutritional genetics reports for people interested in knowing what foods, supplements and lifestyle habits are most beneficial to health, aging and optimal performance.

Nutritional medicine has become so advanced.
Guessing what might work is no longer necessary.
We can test!
