ABOUT
Functional Weight Loss & Wellness Clinic
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 bodies, health, and mood, by uncovering the root causes of weight gain, fatigue, and pesky symptoms that conventional medicine often overlooks.
On average clients often lose 5 pounds in 5 days and see an 88% improvement in symptoms in just 4 weeks.
Think you can handle results like that? Good… because that’s what we do at The Fun Doctor

Frequently Asked Questions
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.
