ABOUT
Dr. Christina Carlyle
At The Fun Doctor Functional Weight Loss & Wellness Telehealth Clinic, we believe true health isn’t just about losing weight – it’s about healing your body, balancing your mind, and restoring your energy naturally.
I’m Dr. Christina Carlyle, a holistic nutritionist, FDN-P (Functional Diagnostic Nutrition Practitioner), and Doctor of Functional Medicine.
For over 20 years, I’ve been helping women (and men) transform their health by uncovering the root causes of weight gain, fatigue, hormonal imbalance, and chronic symptoms that conventional medicine often overlooks.
Now it’s your turn.

Frequently Asked Questions
What kind of training did you receive?
I am a Doctor of Functional Medicine (DFM), Functional Diagnostic Nutrition Practitioner (FDNP), Holistic Nutritionist (HN), Somatic Health Practitioner, and Personal Trainer. I received my doctorate from Rockwell University of Functional Medicine. My pre doctorate education and training is in Functional Nutrition & Holistic Health and Weight Loss. I have received complete training in the biological sciences such as anatomy, physiology, pathophysiology, epidemiology, gastroenterology, endocrinology, and functional blood chemistry. In addition, I have received extensive training in clinical nutrition, botanical interventions, somatic healing practices, and behavior and lifestyle counseling.
Do you prescribe Medication?
Nope, that’s not my lane. I don’t prescribe or adjust prescription medications or controlled substances—that’s a job for your prescribing medical doctor. My role is to help you feel better (and stay better) using safe, natural, and non-invasive approaches. Think nutritional therapy, targeted supplements, functional herbs, stress-relieving techniques, and lifestyle shifts that address the root causes of what’s going on in your body. My goal is to get you back to optimal health and function—without the side effects and frustrations that so often come with a “just take this pill” approach.
Do you take Insurance?
I don’t bill insurance directly. Functional Medicine is still considered “outside the box” by most insurance companies, so the majority of my services are elective and not covered. That said, one of my nutrition programs is eligible for FSA (Flexible Spending Account) funds—which can be a great way to use pre-tax dollars for your health.
At the end of the day, I’d rather spend my time focusing on you—your health, your progress, your results—instead of fighting with insurance paperwork. My goal is to make Functional Medicine approachable, effective, and worth every penny you invest in yourself.
Is Functional Medicine Expensive?
Not at all. Functional Medicine is designed for anyone who wants to feel better and take control of their health. Most of my patients are everyday working and middle-class folks—nurses, teachers, small business owners—people who simply want real answers and lasting results.
The cost depends on a few things: the type of lab testing you may need, which natural therapies or protocols are best for you, and how much support you’d like through webcam visits. I offer flexible care plans as well as full concierge-style Functional Medicine programs, so you can choose the level of care that works for your lifestyle and budget.
My mission is simple: to make Functional Medicine affordable, accessible, and effective for real people around the world—not just the wealthy few. For details, check out the Services Page.
How do I know if Functional Medicine is right for me?
The best place to start is right here—explore the website, browse through the services, and when you’re ready, check out the consultation page to see how we can work together.
Functional Medicine isn’t just my career—it’s my calling. I take your health seriously, but I also believe the process should feel encouraging, supportive, and yes… even fun. Over the months we work together, many of my patients become more than patients—they become friends, and often feel like family.
It’s an honor to be part of someone’s healing journey, and I’d be humbled to walk alongside you on yours.

A tele-health functional health and holistic nutrition practice delivering concierge-level, root-cause care to discerning clients virtually. Experience expert functional healthcare, and lasting results, on your terms.
