Meet Gretchen Spetz, Owner of The Functional Kitchen
Why personalized nutrition and mindset support matter more than ever, and how one coach is changing lives one habit at a time.
Q: Tell us a little about yourself
Gretchen Spetz: I am a registered and licensed dietitian, founder of The Functional Kitchen, and creator of the GLP-1 Success Roadmap. I help people feel confident, strong, and at home in their bodies again. My work blends functional nutrition, mindset shifts, and realistic lifestyle habits so clients can support their physiology with food, movement, and sleep without food guilt, body shame, or diet drama. My one-on-one coaching focuses on sustainable transformation through small, strategic changes that improve energy, support muscle, balance blood sugar and hormones, and create a personalized way of eating that fits each life.

My approach may start in the kitchen, but it goes deeper. Together, we work on nourishing the body and reshaping the way people think about health, food, and self-care. Like many high-achieving women, I know what it’s like to push hard and end up burned out. After years in hospital systems focusing on weight management, diabetes, gastrointestinal disorders, and autoimmune disease, I experienced fatigue, weight changes, anxiety, and digestive issues. Being told everything was “normal” did not feel normal. That experience led me to functional nutrition, where food and lifestyle habits are used proactively to support the body’s natural regulation systems.
I hold a Bachelor’s degree from the University of Notre Dame and a Master’s in Public Health Nutrition from Case Western Reserve University. In 2022, I became an Integrative and Functional Nutrition Certified Practitioner. Before opening The Functional Kitchen in 2018, I was an outpatient dietitian at Cleveland Clinic and University Hospitals of Cleveland. Today, I work privately and through my GLP-1 Success Roadmap, a six-month transformation program for individuals on GLP-1 medications. I live in Bay Village with my husband, Joe, and our two daughters. Outside work, you’ll find me lifting weights, walking, doing CrossFit, paddle boarding, or winding down with ginger tea and a good historical fiction book.
Q: What inspired you to start your business
Gretchen Spetz: I wanted a more powerful way to help patients achieve long-term change. Hospital settings often don’t allow the time or frequency to truly support lasting transformation. I also needed a business model that accommodated my role as a primary caregiver while still allowing me to make a meaningful community impact. I could not find this in traditional spaces, so I created it myself.

Q: What services does your business offer
Gretchen Spetz: My business offers one-on-one nutrition coaching that is highly personalized, meeting clients where they are. We focus on sustainable ways to improve energy, balance blood sugar and hormones, support muscle, and create a way of eating that works with life rather than against it.

I also created the GLP-1 Success Roadmap, a six-month guided program for people on GLP-1 medications. It provides guidance on nutrition, exercise, gut health, and habit changes. These medications are powerful, but they work best with structured lifestyle support. The roadmap helps clients maximize benefits beyond hunger suppression. Many are surprised to learn GLP-1 medications also repair insulin resistance, influence brain pathways related to appetite, and interact with naturally occurring gut hormones such as GLP-1, GIP, PYY, and CCK. The program ensures clients understand this system and use food, movement, and lifestyle habits effectively.
I also partner with providers in medical weight management to establish robust diet and lifestyle programs that support clients on GLP-1 medications.
Q: What makes your business unique
Gretchen Spetz: Coaching is highly individualized. Even when clients work with another dietitian on my team, guidance is tailored specifically to them. The GLP-1 Success Roadmap is an affordable way to access nutrition and lifestyle support, often lacking in medical practices. I describe it as small batch nutrition care. Clients have monthly group sessions and personalized support, so they never feel alone in their journey.

Q: How does your business connect with and contribute to the local community
Gretchen Spetz: I share knowledge and support through presentations for schools and educational organizations, helping educators manage nutrition during busy days. Early in my business, I held monthly cooking classes at The Village Project, which provides meals to people undergoing cancer treatment. I am also a member of the Rocky River chapter of Women’s Working Connection. Supporting the community has always been central to my mission.

Q: How do you help clients shift their mindset around health
Gretchen Spetz: Real health is built through small, daily habits. I coach clients to notice the connection between food, stress, and the nervous system. Mindset work helps people take ownership of their health without shame. Many clients have experienced burnout or been told that “everything is normal” despite feeling unwell. Coaching focuses on internal motivation and self-compassion. We examine what the brain is telling clients and reframe it so they can act without guilt or self-sabotage.

A story that illustrates this approach involves my 11-year-old daughter. She wanted to bring a candy snack to school. Instead of saying no, I reviewed the nutrition facts with her and helped her understand the impact, guiding her to make her own decision. She chose one serving to bring and left the rest at home. Knowledge, thoughtful guidance, and autonomy create lasting learning and change, the same principles applied in my coaching.
Q: What advice do you have for someone looking to improve their health
Gretchen Spetz: Listen to your body with the same respect you give your responsibilities. You do not need a perfect routine; you need sustainable habits. Prioritize protein, fiber, movement you enjoy, time outside, and sleep. Pay attention to your body and trust your instincts. If something feels off, seek support. Habits developed today impact energy, mood, resilience, and overall health for years. Real transformation comes from consistency, awareness, and self-compassion.

Q: How do you help clients see results that last
Gretchen Spetz: Success comes when clients connect the dots between evidence-based nutrition, movement, sleep, and mindset. We focus on small, realistic changes that add up to meaningful transformation. Clients report improved energy, better hormone balance, more stable blood sugar, and a sense of confidence in their bodies. Science, personalization, and self-compassion make the approach effective and sustainable.
