ABOUT
Functional Medicine
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.

Functional Medicine
Uncovers and addresses the root causes of your health concerns
Longer, personalized visits where your story actually matters
Custom nutrition, lifestyle, and supplement protocols designed for you
Natural, non-invasive, non-toxic solutions without unnecessary side effects
Whole-body, integrated approach that connects the dots
Proactive & Preventative approach: optimize your health now so you can prevent illness later
Conventional Medicine
Focuses on managing symptoms instead of finding root causes
Rushed 10-minute visits with little time to discuss your symptoms, full history, lifestyle, and trends in habits
Prescriptions & general advice to "diet & exercise"
Side effects from meds that don’t fix the real issue & flare other symptoms
Fragmented care where specialists/doctors don’t connect the dots
Reactive: wait until you’re sick/diagnosed, then get more meds & generic advice
Why Functional Medicine Works
Most traditional doctors focus on managing symptoms with prescriptions. But if you’ve ever left an appointment feeling unheard, frustrated, or told “your labs look fine” while you still feel anything but fine, you’re not alone.
As a functional doctor, my approach is different. I use advanced lab testing, holistic nutrition, personalized meal planning, and targeted lifestyle protocols to identify and correct the imbalances that are keeping you stuck.
Instead of masking symptoms, we dig deep into the “why” — stress, toxins, gut health, hormones, inflammation, and metabolism – so your body can finally heal and function the way it’s supposed to.
