"Within 2 weeks I felt a huge difference"


I've always been athletic, having been a college athlete and former 4-time national Judo champion, but for the past 2 years, I've struggled with severe joint pain throughout my body, particularly my knees. It was difficult to stand up and I would literally break a sweat from the pain when I walked down the stairs in my house. I thought surgery was the answer, so I sought an opinion from the head orthopedic surgeon at world-renowned Loma Linda Hospital and had surgery on both knees. After my recovery, I felt great for about 2 months, but soon after the inflammation and pain returned. 

After living in pain for 2 years and wasting thousands of dollars on medical bills, I finally contacted Dr. Zitt, who quickly diagnosed my condition, which was confirmed by my blood work. Within 2 weeks of being on the protocol Dr. Zitt recommended, I felt a huge difference and now, in week six, I'm back in the gym, feeling amazing and I've lost 14 pounds. 

I want to thank Dr. Zitt and his team for all their professionalism and care in helping me find a solution to my condition.

"I was quickly put at ease"


Most medical professionals make you believe that once you have diabetes and high blood pressure, you have it for life, but Perfect Human Function is working passionately to debunk that myth. Dr. Zitt teaches you how to take control of your health to get your quality of life back or optimize wherever you are. In 4 months I have lost 28lbs and 11.5 inches from my waist. I'm back to pre-diabetic range and my blood pressure is under control. Never being involved with a virtual practice, I was unsure how it would work for me. I was quickly put at ease because Dr. Zitt personalizes the program specifically for each individual and maintains close contact with you throughout your journey.

"I simply have a much better mindset about my overall health"


Without a doubt, Dr. Zitt has been the most thorough and meticulous physician I've ever worked with. From our very first encounter, I was impressed by his attention to detail and investment in my health. His unmatched intelligence and skill pair incredibly well with his heart and desire to see each of his patients thrive at a level of optimal health.

My anxiety has calmed, my blood glucose levels have significantly improved, and I simply have a much better mindset about my overall health!

"Dr. Zitt has completely changed my way of life"


Dr. Zitt has completely changed my way of life this year after symptoms I had been struggling with symptoms that had slowly been building over the past 10 years. Years ago I developed unexplained chronic hives and was seeking answers and help over the years from allergists, immunologists and internal medicine providers that lead to no answers. The treatment I received from previous providers was just masking symptoms without truly knowing what was causing it. I even had an an immunologist tell me they do not bother to try to find out what is causing my body's reaction as there are too many possible root causes to figure it out. In the past providers would either prescribe prednisone, which left me with the same symptoms and feeling sick from medication or told me to be thankful that allergy pills were lessening my symptoms. This all got worse in the beginning of 2021 with an exacerbation that was almost unbearable. 

I found out about Dr. Z through a friend and he was the first provider to truly listen to my symptoms and started pairing them to organ systems and potential root causes and thinking through an extensive diagnostic and treatment plan. The plan addressed not only my current hive symptoms, but also underlying GI issues I have had since gallbladder removal over 10 years ago. 

I worked through a wellness plan with Dr. Z over the course of 3 months and have never felt better. I can honestly say this has been a true lifestyle change and not just a diet or fad for a small period of time. I have lost 20 lbs and have continued to lose weight through healthy nonrestrictive diet and exercise. 

The care I received with Dr. Z and his wife Melissa was highly personalized and specific to me and my needs instead of one plan that everyone gets based on the same symptom. I have never received this high level of care from any practitioner or clinic I have visited in the past. I highly recommend Dr. Z to anyone suffering from chronic conditions or unexplained symptoms looking for answers and wanting to live an overall healthier life.

"My energy level has tripled and my focus is on point"


I just wanted to say thank you so much for all of your recommendations for me. During the last 2 months I have been able to lose over 25 pounds and more than 2-1/2 inches from my waist!! And I don't even feel like I'm trying to, but it's happening. My new diet, or should I say lifestyle, is amazing! You know I struggled at the beginning and you really encouraged me to keep going, so I did.

The result is now my energy level has tripled, my focus is on point and I can remember stuff that I have never been able to, like people's names and appointments! I have fallen in love with eating whole foods and feeling the energy I get from every meal. I didn't know that I would be able to tell different effects from different kinds of food or that I could feel this good! I can't wait to see how much better I will feel tomorrow, or next week, or next year!! It just occurred to me why you named your business "Perfect Human Function!!!!

Once again THANK YOU!!!!!!
