One of the most common things we hear from patients who walk into the Functional Medical Institute is this: "my doctor reviewed my results and said everything looks fine but I still feel exhausted, foggy, and stuck." Here is the part nobody is talking about: The reference ranges on your lab report were not built around healthy people. They were built around the average of everyone who gets tested at that lab, including the chronically ill, the medicated, and the metabolically compromised. Fasting insulin is a good example of exactly this 🔬 The standard reference range allows up to 25 mIU/L but in our practice, we want to see it under 5. A patient sitting at 18 will be told they are completely normal while that same patient is storing fat instead of burning it, crashing every afternoon, dealing with cravings they cannot explain, and developing insulin resistance that will not show up as a diagnosis for another decade. This gap between what is called normal and what we call optimal is exactly where chronic disease builds for years before anyone puts a name on it and it is the reason this community exists. Over the coming weeks, we will be sharing the markers we actually test, what optimal looks like for each one and the clinical framework behind why it matters for your energy, your weight, your hormones, and how fast you are aging 💡
