    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 resets Check out the Habit Healers Community: https://www.skool.com/habithealers/about Dr. 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

    The Research Shows One Object Is the Most Efficient Tool to Train Grip, Power, and Balance at Once.

    Why does grip strength predict how long you’ll live better than your blood pressure does? In this episode, I dig into the science of muscle power, grip strength, and longevity, and why the strength that keeps you independent as you age is not the kind you build with slow, heavy lifting. Most of us assume that staying strong is about how much we can lift. But here’s the part most people miss: as we age, power declines faster than raw strength, often twice as fast, and power is what catches you when you stumble, gets you up off the floor, and lets you step off a curb without thinking. I walk you through what the research actually shows, including a study of more than a hundred thousand adults linking grip strength to all-cause mortality, and a six-month trial in previously inactive older adults that moved nearly every marker of aging in the right direction. Then I get practical. I explain why a single kettlebell is one of the best home tools for building functional strength, power, and balance in a few square feet, and I lay out exactly how to start. What you’ll learn in this episode: * Why muscle power, not just strength, is the key to aging well and staying independent * How grip strength works as a signal for whole-body muscle health and longevity * What kettlebell training did for grip strength, walking distance, and balance in adults aged 59 to 79 * Why twelve minutes of swings can build both strength and explosive power * How to choose your first kettlebell and progress safely without getting hurt * A simple ten-minute, three-day-a-week beginner routine to start this week Check out the Habit Healers Community: https://www.skool.com/habithealers/about Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/the-single-piece-of-iron-that-trains Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

    What’s Your Heart’s GPA?

    What’s your heart’s GPA? The American Heart Association built a cardiovascular health score called Life’s Essential 8, and the average American adult is pulling a D+. In this episode of The Habit Healers Podcast, I walk you through the eight measures that determine your heart health, why a single composite score is more useful than any one lab value, and how to figure out which habit to change first. The Life’s Essential 8 framework scores you from 0 to 100 across four health behaviors (diet, physical activity, nicotine exposure, and sleep) and four health factors (BMI, blood lipids, blood glucose, and blood pressure). I break down what each component measures, the exact scoring thresholds the AHA uses, and the research showing why people with high cardiovascular health live longer, age slower biologically, and lower their risk of heart disease, stroke, dementia, and diabetes. Then I give you the one-metric strategy I recommend to my patients instead of trying to overhaul everything at once. What you’ll learn in this episode: * How to calculate your own cardiovascular health score using Life’s Essential 8 * Why non-HDL cholesterol and sleep duration matter more than most people realize * The connection between Life’s Essential 8 scores, biological age, and life expectancy * How to use the AHA’s free My Life Check tool to assess your heart health * Which single habit to change first if your score is lowCheck out the Habit Healers Community: https://www.skool.com/habithealers/aboutDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/whats-your-hearts-gpaA Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  4. Your Fat Cells Just Walked Off the Job. Here's Who Got Left Holding the Bag.

    Your Fat Cells Just Walked Off the Job. Here's Who Got Left Holding the Bag.

    Can someone at 220 pounds be metabolically healthier than someone at 155? In this episode, I explain why the real driver of type 2 diabetes and insulin resistance isn’t how much fat you carry, but whether you’ve exceeded your own personal fat storage capacity. I walk you through what I call the garage model of metabolic health: the idea that your fat tissue has a fixed number of parking spaces, and trouble begins only when that garage fills up and fat starts spilling into your liver, muscles, and the space around your organs. This is where fatty liver disease, rising triglycerides, and high blood sugar actually come from. I break down the cascade one domino at a time, from overloaded fat cells to visceral fat, to a fatty insulin-resistant liver, to the cholesterol changes that standard testing often misses. Then comes the hopeful part. I explain why this cascade reverses in a predictable order, why your pancreas may be recovering rather than failing, and why diabetes remission depends far more on losing enough weight than on where you started. What you’ll learn: * Why metabolically healthy obesity and thin people with high blood sugar both come down to fat storage capacity * How visceral fat and fatty liver disease quietly drive insulin resistance * Why your triglyceride-to-HDL ratio and ApoB can catch problems years before a glucose test * The order in which liver, lipids, and the pancreas recover during diabetes reversal Which blood markers and labs to request, including HOMA-IRCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/your-fat-cells-just-walked-off-the Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  5. What If Your Fatigue, Your Belly Fat, and Your Brain Fog All Have the Same Root Cause?

    What If Your Fatigue, Your Belly Fat, and Your Brain Fog All Have the Same Root Cause?

    Your blood sugar looks normal, your HbA1c is fine, and your doctor says you’re healthy. So why are you exhausted by 2pm, carrying weight around your middle that won’t budge, and walking into rooms forgetting why? In this episode, I explain why standard blood work misses insulin resistance, the upstream driver behind so many of the symptoms people are told to ignore. I’m Dr. Laurie Marbas, and on The Habit Healers Podcast I walk you through what fasting glucose and HbA1c actually measure, and what they leave out. We talk about why fasting insulin is the test almost no one orders, how your pancreas can keep your numbers looking perfect for years while damage builds underneath, and the link between insulin resistance and type 2 diabetes, heart disease, fatty liver, PCOS, and even brain health. Then we get to the good news: this is reversible. I share the exact sequence of small daily habits, starting with blood sugar, that builds metabolic health the way a flywheel builds momentum. What you’ll learn in this episode: * Why a normal fasting glucose can hide insulin resistance for years * The one blood test to ask your doctor for: fasting insulin * How insulin resistance connects to type 2 diabetes, heart disease, and Alzheimer’s * Why walking 10 minutes after your largest meal steadies blood sugar * How a continuous glucose monitor turns your body into a real-time experiment The habit-stacking system that makes healthy choices automaticCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-your-fatigue-your-belly-fat Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  6. What Does It Mean When Your Fasting Glucose Is "Normal" but Your A1c Keeps Climbing?

    What Does It Mean When Your Fasting Glucose Is "Normal" but Your A1c Keeps Climbing?

    Your fasting glucose is normal, but your A1c keeps climbing, and no one can tell you why. In this episode of The Habit Healers Podcast, I’m walking you through exactly what that gap means, why post-meal blood sugar spikes are the hidden driver of rising A1c in most people, and the nine habits that target the hours your fasting blood draw never sees. I’m Dr. Laurie Marbas, a board-certified lifestyle medicine physician, and this is one of the most common patterns I see in my practice. A patient comes in with a “normal” fasting glucose of 95 and an A1c that’s quietly drifting from 5.1 to 5.4 to 5.6, and they’re told everything is fine until suddenly it isn’t. The research actually shows that for people in this early-warning zone, postprandial glucose accounts for roughly 70% of the total problem, and it deteriorates years before fasting numbers move. We’ll cover the labs most doctors don’t order, including fasting insulin and HOMA-IR, why a whole food plant-based diet remains the most powerful lever for reversing insulin resistance, and the small, doable habits that smooth out blood sugar spikes after meals. What you’ll learn in this episode: * Why fasting glucose misses postprandial blood sugar spikes and what that means for prediabetes risk * The specific lab tests to ask for, including fasting insulin, HOMA-IR, fructosamine, and CGM time-in-range * How meal sequencing and a 10-minute post-meal walk can lower post-meal glucose by up to 37% * Why a whole food plant-based diet improves insulin sensitivity at the cellular level * How sleep, stress, and hydration quietly drive glucose dysregulation * When to ask your doctor about iron deficiency and other conditions that distort A1c Check out the Habit Healers Community: https://www.skool.com/habithealers/about 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

  7. Why Are the Fast Eaters Three Times More Likely to Carry Belly Fat?

    May 22

    Why Are the Fast Eaters Three Times More Likely to Carry Belly Fat?

    Fast eaters are more than three times as likely to carry belly fat, even when they’re eating the same food as slower eaters. In this episode of The Habit Healers Podcast, I walk you through the science of why eating speed quietly shapes weight, blood sugar, and metabolic health, and what to do about it. We dig into the gut hormones that tell your brain you’re full, GLP-1, CCK, and PYY, and why they need about twenty minutes to catch up to your fork. I share what researchers found when seventeen volunteers ate the same ice cream in five minutes versus thirty minutes, why chewing alone changes your hormone response, and what a six-year study of nearly 60,000 adults revealed about people who shifted from fast to slower eating. I’ll also tell you about a small German trial where six men lost a median of eleven percent of their body weight by simply slowing down at the table, and kept it off for almost two years. Then I walk you through this week’s habit, The Slow Bite, a simple twenty-minute mindful eating practice you can start at your next meal. What you’ll learn: * Why fast eating is linked to belly fat, metabolic syndrome, and weight gain * How GLP-1, CCK, and PYY create your natural “stop eating” signal * Why chewing more slowly may reduce calorie intake by around twelve percent * The connection between stress, eating speed, and overeating A simple twenty-minute mindful eating habit you can start this weekCheck out the Habit Healers Community: https://www.skool.com/habithealers/aboutDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/why-are-the-fast-eaters-three-times Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  8. What If Your Blender Could Replace Every Bottled Sauce in Your Fridge?

    What If Your Blender Could Replace Every Bottled Sauce in Your Fridge?

    When Tim Gannon walked into the kitchen at the Pyramid Bistro in Aspen, Chef Martin Oswald figured he was a salesperson. Martin let him stand there for ten minutes. Gannon didn’t seem to mind. When Martin finally acknowledged him, Gannon rattled off every flavor on the menu that night, sage and allspice and the rest, with the precision of someone who had spent his life thinking about food at this level. Then he introduced himself as the founder of Outback Steakhouse and asked Martin to develop the sauces and spice blends for a new restaurant chain. What Martin learned from that project is something most home cooks never think about. Chain restaurants succeed or fail based almost entirely on their sauces. The rice and broccoli are more or less the same from kitchen to kitchen. What makes people come back, what makes a thousand different locations taste like the same place, is what goes on top. Martin went through five rounds of tastings with the CEO team before a single sauce was approved. That’s how much it mattered. And here’s what makes this relevant to your Tuesday night dinner. The same principle applies at your kitchen table. Martin keeps about forty sauce recipes in his portfolio, but his advice for home cooks is to find three to five that your household genuinely loves and get comfortable making them on repeat. When he caters events for a thousand people, the strategy is identical. Good sauces on the table, everyone’s happy. The problem is that most of the sauces people reach for work against them. A standard barbecue sauce starts with ketchup, which is roughly half corn syrup, then piles more sugar on top. An Alfredo runs about five hundred calories of butter, cream, and cheese before you’ve touched the pasta. These sauces taste good because fat and sugar are the easiest buttons to push for flavor. But they aren’t the only buttons. The Habit Healers is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber. Two Sauces, One Principle During our live session this week, Martin built two completely different sauces to demonstrate a single idea. Every sauce, whether it’s barbecue or cream-based or a vinaigrette, needs four things working together. Something for viscosity, something for acidity, a spice layer, and a backbone ingredient that keeps the whole thing from tasting flat. Once you understand those four components, you can build dozens of sauces without ever opening a bottle. For the barbecue sauce, dates replace corn syrup. They handle both jobs that corn syrup does in a traditional recipe, providing sweetness and that thick, sticky texture that makes barbecue sauce cling to food. Passata, a thick Italian tomato puree, replaces the ketchup. Toasted spices go in layered rather than singular. Martin uses chili powder alongside chipotle flakes rather than picking just one, because layering different forms of heat creates complexity that a single spice can’t. Dijon mustard acts as an emulsifier, binding everything together the same way it holds a vinaigrette in suspension. Mulberry or pomegranate molasses provides the deep, dark tartness that traditional molasses would. Apple cider vinegar adds acidity. Everything goes into the blender. The finished sauce has no salt, no refined sugar, and no oil. And when Martin tasted it on camera, his eyebrows went up and he went quiet, which is how you know it’s actually good. One detail worth stealing from his process. He tasted the sauce on a carrot stick, not off a spoon. A sauce eaten straight should taste intense. What matters is how it tastes on the food you’ll actually serve it with. That’s a professional habit most home cooks skip. Thanks for reading The Habit Healers! This post is public so feel free to share it. The Sauce Nobody Expects The second sauce started with frozen English peas, which sounds like the least promising sauce ingredient imaginable. But peas bring three things to a blender that most people don’t realize. Their soluble fiber creates a smooth, creamy viscosity without any cream. They carry about four to five grams of natural sugar per hundred grams, which is enough sweetness to keep a sauce from tasting flat. And they puree into a bright green that looks genuinely beautiful on a plate. Martin built this one as what he called a freestyle, applying the same four-component framework with completely different ingredients. Fenugreek, coriander, and black pepper toasted in a dry pan for the spice layer. Almond butter as the binder and a source of fat to help absorb fat-soluble vitamins. Lemon rather than vinegar for a gentler acidity that pairs better with the peas. And fresh horseradish, grated directly in, for backbone. Horseradish is a cruciferous vegetable, nutritionally in the same family as broccoli, and it provides enough heat to balance the natural sweetness of the peas without overpowering them. The finished sauce can stand in anywhere you’d reach for a cream-based sauce. Pasta, roasted vegetables, grain bowls, crudités. At a fraction of the caloric load and with actual nutrients instead of saturated fat. Why This Changes More Than You Think The real takeaway from watching Martin work is that the viscosity and richness you associate with butter and cream and sugar can come from whole foods you already have access to. Dates, peas, cauliflower, corn, silken tofu, soaked cashews. Each one creates a different style of sauce base, and each one lets you skip the calorie-dense ingredients that make most sauces a metabolic problem rather than a metabolic asset. If you’ve been buying bottled sauces because you assumed the homemade alternative would be complicated or bland, this is the week to test that assumption. Pick one of these two sauces, make it once, and taste it on whatever you’re already eating. Here is Martin’s 40 Sauce Recipe Index.
