At Sheila Jackson's Fort Worth-based FDN practice, she provides a space where your voice is valued, your lived experience is heard, you are empowered, and your health challenges are resolved. Her mission? To liberate you from the constraints of conventional medicine and guide you towards a healthier life as you age. 

Sheila's focus is on metabolic health across body systems, hormone optimization, digestive, and autoimmune issues. Conventional medicine has its merits, but it often provides only temporary symptom relief.

For much of modern medical history, healthcare has operated on a reactionary model: wait for illness to surface, identify the symtpoms, and suppress using pharmaceutical interventions that have led to a culture of short-term fixes. It's like patching a leaky pipe with duct tape: the flow might stop temporarily, but the underlying structural problem persists and continues to silently grow.  Sheila steps in when you feel you've exhausted all options. 

Helping You Get Answers

Sheila's approach is thorough and precise. As a new client, you can expect her to delve into every aspect of your life and gently guide you to understand why previous health strategies have failed to provide you with better results. Her customized treatment plans and protocols cater to your data, unique strengths, and challenges, ensuring a personalized journey toward optimal metabolic health outcomes. 

Like many women, Sheila has had her own metabolic health story and has struggled to get answers that would help her improve her health within the conventional medical model. Being passionate about high achievement, transformation, and personal growth has driven Sheila for over three decades in entrepreneurial and consulting roles across healthcare and fitness, nutrition, hormone research, and the refinement of human behavior that forms an atomic alliance with the sophisticated biology of a woman's body. She believes in the power of nature to nourish our bodies, is fascinated by the psychological aspects of dietary choices, and is unshakably confident in YOU and your body's innate ability to self-heal when given the right environment. 

An Education in Functional Nutrition 

After completing a rigorous certification program in Functional Diagnostic Nutrition (FDN), Sheila began practicing nationwide, offering a hybrid model of both in-person and virtual healthcare services. Since March 2021, she's tested and interpreted, refined, and shared her method with hundreds of high-achieving women (and some men, too) who found their way to her practice not through advertising, but through word-of-mouth—women sharing their transformation stories with family, friends, and colleagues. Women who once felt invisible, unheard, misunderstood, irrelevant, and dismissed by the medical system are now women who routinely experience metabolic breakthroughs, sauntering rather than smashing into, seasons of biological change and aging.  

Sheila's qualifications extend beyond her acronyms. She realized that educating people on the connection between what they put in their bodies, hormones, and how they feel was insufficient, so she pursued health coaching and hormone literacy. Sheila was part of the founding cohort that earned certification as a Functional Medicine Certified Health Coach (FMCHC) through the Functional Medicine Coaching Academy (FMCA), in collaboration with the Institute for Functional Medicine (IFM). She was also an adjunct faculty member at FMCA for two years.

Passionate about education, Sheila continues to learn more about why the body may lose function and what it takes to restore it. She holds the following certifications:

• One of the first National Board-Certified Health and Wellness (NBHWC) coaches in the United States, accredited by the International Consortium of Health and Wellness Coaching and the National Board of Medical Examiners.
• LEAP (Lifestyle, Eating and Performance) therapist – Group of nutritionists and Functional Medicine Practitioners that identify food sensitivities through testing and help people manage the findings.
• Reversing Cognitive Decline – Through FMCA in collaboration with Dr. Dale Bredesen, who specializes in Alzheimer’s. He is the author of “The End of Alzheimer’s” and established the ReCode Protocol.
• Methylation and Clinical Nutrigenomics in collaboration with Dr. Ben Lynch at Seeking Health. Focused on DNA and genetic predisposition and its connection to epigenetics and nutrigenomics. Sheila learned how behavior can affect our genetics; food and nutrients can influence how. 
• Fast Like a Girl Certified Coach, in collaboration with Dr. Mindy Pelz. Sheila learned how fasting behavior can influence hormone balance and optimal health outcomes.

Sheila has also completed the following courses for the benefit of her clients:

• Mastering Thyroid
• Mastering Functional Blood Chemistry
• Functional Endocrinology: Connecting New Research with Practical Applications
• The Gluten, Leaky Gut, Autoimmune Connection
• Dietary Supplement Specialist 

Stay Close to Nature—Stay Far From Disease

Sheila's philosophy centers on Test, Don't Guess, and our bodies thrive best on nature's foods. She appreciates the beauty of food and its potential to nourish us — use food as your pharmacy first. Sheila firmly believes in the healing power of nature and often says in conversations with clients, “The further away we get from nature, the closer we get to disease.”

Her Guiding Principles 

Sheila is grounded by faith, not fear. Our bodies are remarkable, highly regenerative, and always working to support us without our conscious thought, moving resources on our behalf every moment of the day, keeping us alive despite the chronic assault of modern living. If we give the body what it needs and remove what it doesn’t, it will most often perform at a high level. Sheila is your advocate and is confident in her ability to help you help yourself.

Back to Basics & On the Path to Better Metabolic Health 

In Sheila’s practice, simplicity reigns supreme. Why complicate things when we can return to the basics of fasting, quality food and water, movement, good sleep hygiene, supplementation, friendship, community, purpose, play, love, and spirituality (many of which are free)? This is how we were designed to live, not in sickness but in wellness.

Sheila is more than a listener; she is a longevity accelerator who offers encouragement, hope, science-backed tools, and a functional path forward. She partners with you to initiate change, affirming that a better, healthier life is within reach. With her blend of knowledge, experience, empathy, science, and functional solutions, she’s ready to help you become one of the 6.8% of metabolically elite women in America.
