What Happens Between "Normal" and Prediabetic That Nobody Warns You About

Your fasting glucose is normal, so why is your A1c going up? If that question has ever left you confused, this episode is for you. I’m Dr. Laurie Marbas, and on The Habit Healers Podcast I explain why a single morning blood draw can miss the most important window in your metabolic health: the hours after you eat.We start with a surprising idea borrowed from engineering, a 1949 mathematical proof about how often you need to measure something to actually see it, and I show you why fasting glucose samples your body thousands of times too slowly. Those after-meal spikes, called postprandial glucose, are where the early warning signs of insulin resistance and prediabetes quietly show up first, often years before your fasting number ever moves. Even people with completely normal labs can spend three or more hours a day with blood sugar above 140. Then I walk you through the fuller picture you’re allowed to ask your doctor for, and nine practical habits that start where the science is strongest: the quality of the food on your plate.In this episode, you’ll learn:* Why normal fasting glucose with a rising A1c is so common, and what it really means* How postprandial glucose spikes drive most of your blood sugar problem early on* Which tests to ask for, including fasting insulin, HOMA-IR, and a continuous glucose monitor* What “time in range” is and why it tells you more than years of fasting draws* How a whole food, plant-based diet improves insulin sensitivity at the cellular level* Simple habits like meal sequencing, post-meal walks, fiber, sleep, and stress resetsCheck out the Habit Healers Community: https://www.skool.com/habithealers/aboutDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-does-it-mean-when-your-fasting Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
