  What If the Most Powerful Thing in Your Kitchen Is Something You Already Drink? 20.08.2026 29min

  What are the healthiest teas to drink every day? In this episode, I open up my tea medicinal cabinet: six teas backed by real research, from hibiscus tea for blood pressure to chamomile tea for better sleep.I’m Dr. Laurie Marbas, and on The Habit Healers Podcast today, we’re looking at what the science actually says about the health benefits of tea, and where popular claims quietly stretch the evidence. You’ll hear why green tea drinkers aged 50 to 69 showed a 37% lower risk of cognitive impairment, why hibiscus tea performed comparably to some blood pressure medications in controlled trials, and what a large analysis of nearly 2 million people found about tea and heart health. We’ll also cover chamomile tea for sleep quality, peppermint tea for digestion, ginger tea for nausea, and the honest answer to when a supplement is the better choice than the cup. Plus, exactly how to brew each one so you get the most from every steep.What you’ll learn:* The six healthiest teas to stock in your cupboard and why each one earned its spot* How hibiscus tea may help lower blood pressure naturally, and who benefits most* Green tea benefits for brain health and longevity in regular tea drinkers* Chamomile tea for sleep: what it improves and what it doesn’t* Peppermint tea for digestion and ginger tea for nausea: when tea works and when to consider the capsule* Brewing temperatures, steep times, and the best time of day for each teaDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-the-most-powerful-thing-inCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  What If the Best Time to Exercise Is Right After You Put Down Your Fork? 19.08.2026 9min

  Walking after eating is one of the simplest ways to lower blood sugar naturally, and in this episode I explain exactly why a 10-minute walk after meals can blunt glucose spikes better than a longer workout at the wrong time.Here’s what most people miss: your fasting blood sugar can look perfectly normal at your annual checkup while your post-meal glucose is quietly climbing, decade after decade. That slow slide toward insulin resistance and prediabetes happens after lunch and dinner, not in the morning blood draw. The good news is that your muscles have a second pathway for pulling glucose out of the bloodstream, one that works completely independent of insulin. Every time you walk, your leg muscles open that door on their own. In this episode of The Habit Healers Podcast, I walk you through the research on post-meal walking, including why timing matters more than duration, why dinner is the meal where a short walk pays off most, and how to start this habit on Monday with zero equipment.What you’ll learn:* Why blood sugar spikes after meals drive insulin resistance and type 2 diabetes risk* The insulin-independent pathway your muscles use to absorb glucose during light walking* Why a 10-minute walk started right after eating flattens the glucose spike better than a delayed 30-minute walk* Why walking before a meal does not blunt the post-meal spike* How walking breaks reduced post-meal glucose by about 17% compared to sitting* The one meal to start with if you only pick oneCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  Who Designed Your Craving? (Hint: It Wasn’t You) 18.08.2026 26min

  Why can’t you stop eating ultra-processed foods? It’s not a lack of willpower. In this episode, I break down 17 techniques the food industry uses to override your hunger and fullness signals, and give you simple checks to spot every one of them.As a lifestyle medicine physician, I hear it constantly: “I know better, but I can’t stop.” Here’s what I want you to know. Food companies employ scientists whose entire job is engineering hyperpalatable foods that keep you eating past full. In this episode, we look at the bliss point, vanishing caloric density, the fat and carb combination that barely exists in nature, and why variety packs are designed to defeat your brain’s natural off switch. Then I walk you through my Food Defense Protocol: practical steps for reading food labels, catching hidden sugars, auditing liquid calories, and building healthy eating habits that work with your biology instead of against it. If you’ve been blaming yourself for food cravings and overeating, this conversation will change how you see every package in your pantry.What you’ll learn:* What the bliss point is and how companies calculate the exact sugar, salt, and fat ratio that maximizes cravings* Why foods that melt in your mouth bypass your fullness signals* The fat and carbohydrate combo that hijacks your brain’s reward system* How hidden sugars get split across five or six names on the ingredient list* The Food Defense Protocol: seven checks to protect yourself from ultra-processed foods* Why liquid calories are the biggest blind spot in most dietsDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/who-designed-your-craving-hint-itCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  What If Your Doctor Is Wrong About Aging? 17.08.2026 33min

  Is your biological age older or younger than your birthday? In this episode, I break down the 12 hallmarks of aging, how epigenetic clocks measure how fast you’re actually aging, and how to slow biological aging naturally with habits you can start this week.Here’s what most of us were never told: two people born the same year can be a decade apart biologically, and that gap is not random. It’s driven by twelve identifiable processes, from chronic inflammation and cellular senescence to mitochondrial dysfunction and gut dysbiosis. The best part? Randomized trials show that everyday choices, like an anti-inflammatory diet, regular exercise, quality sleep, time-restricted eating, and stress management, can measurably slow the pace of aging, and in one eight-week trial, even reverse epigenetic age. We’ll also talk about the debate over whether aging is a disease, what DNA methylation tests like DunedinPACE actually tell you, and where longevity science is headed next.What you’ll learn:* The 12 hallmarks of aging and how each one shows up in your body* How epigenetic clocks and DNA methylation testing measure biological age* The clinical trials showing lifestyle changes can slow and even reverse biological aging* How fasting and time-restricted eating activate autophagy, your cells’ recycling system* Why chronic inflammation and gut health accelerate aging, and the foods that help* What to know before buying a biological age testDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-your-doctor-is-wrong-aboutCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  The Walking Women and the Doctors Who Tried to Stop Them 16.08.2026 10min

  Walking after eating is one of the simplest things you can do for your blood sugar, and the research says the timing matters more than the distance. In this episode I trace that idea back to a nineteenth century medical mistake that told sick women to lie still and do nothing.I’m Dr. Laurie Marbas, and this is one of my favorite stories in medicine, because it shows how long it can take for science to catch up with what people already knew in their bodies. In the 1880s, a diagnosis called neurasthenia was treated with weeks of enforced bed rest for women, while men with the same diagnosis were sent West to ride, hunt, and work outdoors. We now know what prolonged immobility does to cardiovascular capacity, insulin resistance, and muscle. We also know what movement does for depression, and what a short walk at the right moment does for post-meal glucose. Three groups of women figured out the movement part long before the studies existed, and I want to tell you about all three.What you’ll learn in this episode:* Why prolonged bed rest damages cardiovascular fitness, insulin sensitivity, and muscle mass* What a large 2024 analysis found about physical activity and depressive symptoms* Why walking after a meal lowers blood sugar more than the same walk at another time of day* Why the effect is strongest after the evening meal* The exact fifteen minute post-meal walking habit to start this weekDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-the-most-important-discoveryCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  There Is a Pharmacy Built Into Your Muscles. It Has One Rule: No Contraction, No Prescriptions. 15.08.2026 26min

  Your muscles are an endocrine organ. Every time they contract, they release myokines, chemical signals that travel to your brain, your bones, your fat cells, your gut, and your immune system. Most of us were never told this, and it explains why you can walk thirty minutes a day for three years and still watch your bone density fall and your inflammatory markers drift upward.In this episode, I walk you through the eight organs that receive signals from contracting muscle, and what happens to each one when the signal stops. We talk about why myokine release is contraction dependent, which means a large muscle sitting in a chair all day sends nothing at all. I explain why interleukin-6 released from working muscle behaves like a completely different molecule than the IL-6 you may have read about as an inflammatory marker. Then I give you the schedule itself: five movement days a week, one long walk, interval walking sessions, two resistance sessions for bone, and breaking up prolonged sitting.What you’ll learn:* What myokines are and why skeletal muscle functions as an endocrine organ* Why walking alone may not protect bone density, and which chemical signals actually build bone* How muscle contraction triggers natural GLP-1 release, the same hormone targeted by the new weight loss drugs* Why interval walking training outperforms continuous walking at matched energy expenditure* How exercise lowers chronic inflammation by suppressing TNF and raising anti-inflammatory signals* Why the number of days you move matters more than your total weekly exercise minutesDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/there-is-a-pharmacy-built-into-yourCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  The Walking Protocol That Lowered Blood Pressure as Much as Medication, and It Costs Nothing 14.08.2026 20min

  Japanese walking, also called interval walking training, is the walking method that actually lowers blood pressure, and the research behind it is almost twenty years old. If your daily walk has not moved a single number on your lab work, this episode explains why.I’m Dr. Laurie Marbas, and on this episode of The Habit Healers Podcast I walk you through the science of interval walking: three minutes fast, three minutes slow, repeated five times. In the original randomized trial of 246 adults with an average age of 63, the interval walkers gained 13% more knee extension strength, raised their aerobic capacity by 8 to 9%, and dropped their systolic blood pressure by 9 mm Hg. The steady-pace walkers, matched for total energy expenditure, showed no significant gains in leg strength or aerobic fitness at all. Then I get into the variable nobody expected, the one time measurement that predicted results across 679 people, and what it means for how you should be tracking your walks.What you’ll learn:* Why comfortable-pace walking sits below the intensity threshold where your body adapts* The talk test for finding your fast pace and slow pace without a heart rate monitor* Why fast-walking minutes per week, not step counts, is the number worth tracking* The 50-minutes-per-week ceiling where the benefits plateau* How interval walking improved blood sugar control in type 2 diabetes through glucose effectiveness, not insulin sensitivity* A six week progression from three cycles to the full protocolDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/the-walking-protocol-that-loweredCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  What If the Most Important Thing About Your Meal Isn’t What You Eat, But How You Eat It? 13.08.2026 13min

  The order you eat your food in can lower your blood sugar after a meal without changing a single thing on your plate. It’s called meal sequencing, and when researchers had people save the carbs for last, the drop in post-meal glucose was comparable to what you’d see from a diabetes medication.I’m Dr. Laurie Marbas, board-certified lifestyle medicine physician, and in this episode of The Habit Healers Podcast I’m walking you through why eating fiber and protein first changes how your body handles the exact same meal. I’ll explain the two things that happen when vegetables and legumes reach your gut before bread, rice, or pasta: the physical fiber barrier that slows glucose absorption, and the GLP-1 release that protein triggers early in the meal. We’ll look at what happened when people with type 2 diabetes and prediabetes ate identical meals in reversed order, what continuous glucose monitors showed when researchers took this out of the lab and into real kitchens, and why a scoop of black beans belongs at the front of your meal while white bread belongs at the end. I’ll also clear up the confusion around GIP, one of the most misunderstood hormones in metabolism.What you’ll learn:* Why meal sequencing lowers post-meal blood sugar spikes without changing what you eat* How to increase GLP-1 naturally by putting fiber and protein before starch* The difference between rapidly digested carbs and fiber-rich plant carbohydrates* What continuous glucose monitor data showed about time in range with a carbs-last pattern* Why lentils, black beans, and chickpeas serve as the protein course and the fiber course at once* The simple fiber-to-protein question to ask yourself at every plateDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-the-most-important-thingCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  What If Your Daily Habits Could Rewrite Your DNA? 12.08.2026 21min

  Your DNA is not your destiny. In this episode I break down the science of epigenetics: how DNA methylation switches your genes on and off, why your daily habits appear to influence your biological age more than your body weight does, and what that means for you starting today.Every cell in your body carries the same 20,000 genes. A skin cell and a neuron are built from identical instructions. What makes them different is which genes are being read, and that reading pattern stays responsive for your entire life. I walk you through how methyl groups and histone tags open and close your genes, what happens inside a muscle cell within hours of a single workout, and the remarkable finding that your muscles retain an epigenetic memory of training you did months ago. We also look at sirtuins and NAD+, the enzyme system that links movement and energy stress to gene expression and declines as we age. Then I give you the two week reset protocol built from this research, with a printable worksheet.What you’ll learn:* How DNA methylation and histone modification control gene expression without changing your genetic code* Why one session of exercise measurably shifts methylation at metabolic genes* What epigenetic muscle memory means for getting back in shape after a break* How sirtuins and NAD+ connect movement and aging to the same molecular switch* What the epigenetic clock is and how a pilot trial moved biological age in eight weeks* The methyl donor and polyphenol foods that supply the raw materials for methylationDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-your-daily-habits-could-rewriteCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  Everything That Ages Your Eyes, And The Six Habits That Slow It 11.08.2026 18min

  Most people over fifty decide that blurry vision, halos around headlights, and burning eyes at the end of the day are simply what old eyes do. That conclusion is wrong, and it costs them the one part of eye aging they can still change. I’m Dr. Laurie Marbas, and this episode of The Habit Healers Podcast is about what is actually failing inside the aging eye.Your eyes age on three separate clocks. The lens is a closed record, so the stiffening that puts a menu at arm’s length and the scatter that turns headlights into halos are already written, and nothing you swallow undoes them. The thin strip behind your retina is a live system still under active blood supply, and that is where macular degeneration starts and where your daily habits actually reach. Glaucoma runs on a third clock that only shows itself on a measurement. I explain the biology in plain language, then walk you through the Aging Eye Protocol: six habits aimed at the one layer that still answers to you, and the two questions to ask at your next dilated eye exam that decide whether an eye supplement is worth your money or worth nothing at all.What you’ll learn:* Why macular degeneration is really a small blood vessel problem, and how blood pressure and blood sugar drive it* What a Mediterranean eating pattern did to advanced macular degeneration risk in two European cohorts* Why lutein and zeaxanthin need dietary fat to absorb, and the simplest way to do that at lunch* What seventeen randomized trials found when they tested blue light glasses for digital eye strain* How fish oil performed against olive oil in a year-long dry eye trial* When an AREDS-style eye vitamin is worth taking, and the beta-carotene warning to check for tonightDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/everything-that-ages-your-eyes-andCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  Why Your Calf Cramps Up in the Middle of the Night and What To Do About It 10.08.2026 17min

  If you get leg cramps at night, you have probably been told to take magnesium and drink more water. I want to show you what the research actually says, because the real cause of nocturnal leg cramps is not a deficiency. It is the position your foot sits in for seven hours.In this episode I walk through what is happening inside your calf during a cramp, why the nerve firing has no off switch while you sleep, and why the placebo groups in the magnesium trials improved almost as much as the treatment groups. I also cover the one remedy with a surprisingly clear mechanism behind it, pickle brine, and why it works without changing a single thing in your bloodstream. Then I give you the full night cramp protocol: the bedtime calf stretch that actually got results in a supervised trial, how to change the geometry of your bed for free, what to do in the moment a cramp hits, and the medication question worth bringing to your next appointment.What you’ll learn:* Why nighttime calf cramps are a nerve signal problem, not a mineral problem* What the placebo-controlled magnesium trials really found for leg cramps in older adults* The bedtime calf stretch technique that separated the two stretching trials* Why loosening your covers may matter more than any supplement* How to stop a charley horse faster using two pathways at once* Why you should skip tonic water and quinine for leg crampsDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/why-your-calf-cramps-up-in-the-middleCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  6 Evidence-Based Ways to Manage Gas (and 1 That’s Making It Worse) 09.08.2026 21min

  Why do beans cause gas, and why does some gas smell terrible while other gas has no odor at all? Those are two different questions with two different answers, and confusing them is why most gas remedies fail.In this episode I break down what your gut is actually producing. Roughly 99% of intestinal gas is odorless, and the volume that comes from beans, fiber, and resistant starch is the product of healthy bacterial fermentation. The smell is something else entirely. It comes from hydrogen sulfide, made when gut bacteria break down sulfur-containing amino acids that are far more concentrated in animal protein, eggs, garlic, onions, and cruciferous vegetables than in legumes. I also explain why sugar and fructose malabsorption can make gas both louder and worse smelling, what the feeding studies show about how quickly the gut adapts to beans, and why reaching for Beano every day may work against the blood sugar and gut health benefits you chose beans for in the first place.What you’ll learn:* Why bloating after eating beans usually fades within two to three weeks of consistent intake* The difference between managing gas volume and managing gas odor, and which remedies target which* Which foods actually drive smelly gas, and what to cut back on before a flight or a long meeting* How alpha-galactosidase enzymes affect blood sugar and short-chain fatty acid production* What a cup of legumes a day did to hemoglobin A1c in adults with type 2 diabetes* The gas symptoms that mean it’s time to call your doctorDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/6-evidence-based-ways-to-manage-gasCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  7 Outcomes Worth Tracking When Weight Loss Doesn’t Deliver What You Expected 08.08.2026 17min

  GLP-1 weight loss medications like Ozempic are everywhere right now, but the largest weight loss drug comparison ever conducted just revealed something surprising: the scale moved, and quality of life did not. In this episode, I walk you through what that research actually means for you, and the seven measurements that predict how you’ll feel far better than your body weight ever will.I break down the new analysis of 262 clinical trials and nearly 100,000 participants, and why not one of nineteen weight loss drugs meaningfully improved quality of life. We talk about muscle loss during weight loss, why lean muscle mass matters so much after 50, and the research showing that resistance training can flip the ratio so you lose fat while gaining muscle. Then I give you my Beyond-the-Scale Protocol: seven simple things you can track at home with no equipment, from grip strength and chair rises to walking pace, energy, sleep, mood, and waist circumference. If you’re on a GLP-1 medication or losing weight any other way, this is how you protect your strength, your body composition, and your independence while the weight comes down.What you’ll learn:* Why weight loss alone rarely improves quality of life or mood, according to the research* How much lean muscle mass is lost during calorie restriction, and why it matters after 50* How resistance training changes body composition so you lose fat and preserve muscle* The seven at-home measurements in the Beyond-the-Scale Protocol* The two-question self-check that tells you if your weight loss approach is protecting your strengthDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/7-outcomes-worth-tracking-when-weightCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  What If Tonight’s Dinner Could Lower Tomorrow Morning’s Blood Sugar? 07.08.2026 14min

  If your fasting blood sugar keeps coming in higher than you expect, the answer may not be sitting on your breakfast plate. In this episode I break down the second meal effect, the research showing that what you eat at one meal measurably changes how your body handles the next one, sometimes hours later, sometimes the following morning.I’m Dr. Laurie Marbas, and on The Habit Healers Podcast I like to take the science apart and hand it back in a form you can use tonight. We look at how lentils, beans, and whole barley kernels feed your gut bacteria overnight, how those bacteria make short chain fatty acids that set up better glucose control the next day, and why a food’s structure matters more than the fiber number on the label. We also cover what this means if you live with type 2 diabetes, and why two people can eat the same dinner and wake up with very different numbers.What you’ll learn:* What the second meal effect is and why it lowers blood sugar hours later* Why intact barley kernels and lentils improve fasting glucose while the same grains ground into flour do not* How gut bacteria and short chain fatty acids drive overnight glucose control* Why skipping meals weakens the priming effect on your next meal* How the second meal effect works in people with type 2 diabetes* A simple half cup habit you can start at dinner tonightDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-tonights-dinner-could-lowerCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  The Mice Had Unlimited Food, No Predators, and No Disease. They All Died Anyway. 06.08.2026 20min

  Loneliness is now treated as a public health crisis, but the research points to something more specific than being alone. It may be the loss of purpose that does the real damage to your health.In this episode of The Habit Healers Podcast, I walk you through one of the strangest experiments in behavioral science. In 1968, a researcher built a perfect world for mice: unlimited food, unlimited water, no predators, no disease. The colony still collapsed and went extinct, and it never ran out of anything. What it ran out of was meaningful roles.Then we go from metaphor to mechanism. I explain what chronic loneliness does to gene expression, why the stress response stays switched on, and why a sense of purpose appeared to neutralize that inflammatory signal entirely in one study of older adults. We look at the mortality data on social connection, the research showing that people with the lowest sense of life purpose had more than double the mortality risk, and the volunteering study that found the health benefit depended entirely on why people showed up.This one matters if you are navigating retirement, an empty nest, a move, or the quiet drift that follows any major life transition.What you’ll learn:* Why social isolation carries a mortality risk comparable to major clinical risk factors* How loneliness and chronic stress drive inflammation at the level of your genes* Why purpose in life is a measurable survival variable, not a soft concept* The difference between outward-directed and self-directed volunteering, and why only one lowers mortality risk* How to rebuild social structure after retirement or a major life change* Why hormesis, or voluntary challenge, keeps your biological systems functioningDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/the-mice-had-unlimited-food-no-predatorsCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

If you’re over 45 and you’ve walked into a room and forgotten why, or lost someone’s name five seconds after hearing it, this episode is for you.I’m Dr. Laurie Marbas, and on this episode of The Habit Healers Podcast I walk you through how memory actually works inside your brain, and why so much of it is under your control. We start with the patient known as H.M., whose surgery revealed that memory isn’t one system at all but several, running in different parts of the brain. From there I explain how a memory gets built, why sleep is the window where memories get filed for the long term, and how chronic stress and elevated cortisol quietly wear down the hippocampus.Then we get practical. I share the only two study techniques that earned the highest rating in a landmark review of learning research, and why highlighting and rereading rank near the bottom. I give you specific fixes for remembering names, phone numbers, and grocery lists. And I walk through the fourteen modifiable risk factors identified by the Lancet Commission that together account for roughly 45 percent of dementia cases worldwide.What you’ll learn:* Why memory is several separate systems, not one* How sleep consolidates memories and what happens when you lose it* The two highest-rated memory techniques in the research* A step-by-step method for remembering names* The lifestyle habits that protect your brain long term* The red flags that mean it’s time to talk to your doctorDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-you-could-train-your-brainCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  Can You Caramelize Onions Without a Single Drop of Oil? 04.08.2026 44min

  Everything we do inside The Habit Healers comes back to reversing insulin resistance with habits small enough that you actually keep them. The Insulin Resistance Reversal Roadmap walks you through it one station at a time. Martin’s Healing Kitchen sits alongside it with close to three hundred recipes now, including this one. And I go live every Tuesday at 4 PM Pacific for ninety minutes to answer whatever you bring me. Come find us on Skool.Chef Martin Oswald opened this one by telling me we were making dal, and then telling me we were not making dal, at least not the kind you would order at a restaurant. That version arrives with a slick of ghee poured over the top and lands somewhere between six and eight hundred calories a bowl. He wanted the flavor without the clarified butter, and he wanted the spices doing real work on blood sugar instead of sitting there tasting nice.The empty panHe started with onions in a dry ceramic pan over medium heat and nothing else in it. When I asked how he planned to roast them that way, he pointed out that an onion is about ninety percent water and brings everything it needs on its own.So he waited. As soon as brown started showing on the bottom of the pan, he added about a tablespoon of water and the whole thing lifted. The pan went clean, all that caramelized flavor went straight back into the onions, and within a minute the browning started again.He repeated it three or four times for us and said he goes five when he wants it darker. This is how he makes French onion soup without oil, which he cooked by the ton in restaurants back in the eighties. The technique asks for more attention than pouring in oil, and the flavor comes out the same. I watched that pan go from brown to spotless and said “wow” out loud, which is something I do on these Wednesdays more often than I would like to admit.The spices Once the onions were where he wanted them, the whole spices went in to toast. Cracked black pepper first, then fenugreek, mustard seed, and cumin seed. Carrots and red bell peppers followed with a splash of stock, then grated ginger and a lot of pressed garlic.Two things about that garlic. Martin drops the clove into the press with the peel still on, which skips the peeling entirely, and he presses it hard because crushing activates more allicin than chopping does.Then tomato paste, which you will not find in a traditional dal. When you pull the oil out of a dish you lose the backbone that fat provides, and tomato paste puts some of that structure back. The ground spices went in last, Ceylon cinnamon and turmeric and coriander.Cinnamon in a lentil dal is unusual, and Martin put it there on purpose. Fenugreek sits at the top of his list of blood sugar spices, and he was careful to say none of these are a cure for anything. He chooses Ceylon over the cheaper cassia because it carries less coumarin. Turmeric came in for the same reason, and in what he has been reading, garlic outperforms even that. The black cumin, those little onion-family seeds also called kalonji, went in for what they do rather than how they taste, while regular cumin handled the flavor. Even the black pepper at the start was deliberate, since pepper improves how much of the curcumin from turmeric your body absorbs.I added my own note on the live and I want it here too. No single spice is going to move your numbers by itself. What moves them is accumulation, one spice after another, meal after meal, and Martin built this recipe so all of that stacking happens in one bowl. Somewhere in the middle of it I told him he cooks like a mad scientist, and I stand by that.Bring it to a boilA cup and a half of lentils went in with the stock, which feeds four. Then Martin said something no one has ever said to me in a home kitchen. Bring it to a full boil before you drop it to a simmer.Most of us go straight to simmering, and the edges of the pot never come up to temperature. You get uneven cooking and you leave room for bacteria, and a real boil takes care of both. He scraped the bottom of the pot to lift the spices back into the liquid, covered it, and gave it about fifteen minutes.Lentils are done when there is no white left in the center. Al dente is what you want from pasta and from quinoa, and it is not what you want here. To thicken the pot, Martin pressed some of the cooked lentils against the side with the back of his spoon. No blender, no extra dish to wash.Finishing it without the gheeThe traditional finish is a tadka, spices bloomed in hot ghee and poured over the top. Martin heated a dry pan to medium, gave garam masala with sesame seeds and black cumin about twenty to thirty seconds, and poured that over instead. If your sesame seeds are raw rather than toasted, toast them on their own first and add the spices after.Then came the yogurt trick, which is the part I will actually use this week. Plant-based yogurt dropped straight into hot dal breaks apart into flakes, so he spooned a little of the hot dal into the yogurt first, stirred it smooth, and folded that mixture back into the pot. He also pulled the pot off the burner before doing it, because leftover heat will bring the whole thing back to a boil and undo the work.Spinach went in at the end and steamed down into the stew, followed by lemon juice, because a dish without acid tastes flat no matter how good the spices are.No salt went in at all. Martin’s rule for cooking without sodium is to raise the spices by about twenty percent to make up for what you give up from both the salt and the ghee. When he tastes, he is not looking to be impressed with himself. He asks whether there is enough acid and whether anything is missing, then fixes it. If your family wants heat, add more chilies. That part belongs to you.The finished bowl was thick and creamy without a drop of oil anywhere in it, and I was hungry watching it.Martin’s full recipe serves four and you can find it here. If any of this made you want to cook differently, that is what the Habit Healers Skool community is for. Reversing insulin resistance comes down to small habits repeated until they run themselves, and the Insulin Resistance Reversal Roadmap gives you the order to build them in. Martin’s Healing Kitchen has this dal along with everything else he has demonstrated over the past year.

  Sip, Sip, Sigh: Could Three Words Change How Your Nervous System Works? 04.08.2026 12min

  The physiological sigh may be the simplest nervous system regulation tool we have, and it takes five minutes a day. In this episode of The Habit Healers Podcast, I break down the science of cyclic sighing: two short inhales through the nose, one long slow exhale through the mouth.I’m Dr. Laurie Marbas, and I want to walk you through what’s actually happening in your body when you sigh. Your brainstem has a small cluster of neurons dedicated to producing sighs, separate from the circuit that runs normal breathing. That sigh reopens collapsed air sacs in your lungs, but it does something else too. The long exhale is the active ingredient. Because of respiratory sinus arrhythmia, your heart rate rises slightly on the inhale and falls on the exhale, so an exhale-dominant breathing pattern tilts you toward your parasympathetic nervous system, your rest and digest side. I also cover a randomized controlled trial where five minutes a day of cyclic sighing outperformed mindfulness meditation on positive mood, and a study where adults over 45 showed a greater parasympathetic response than younger adults after a single session.What you’ll learn:* How to do the physiological sigh correctly, using the sip, sip, sigh pattern* Why a long exhale activates your vagus nerve and calms your body faster than a deep inhale alone* What the research on cyclic sighing shows for stress, anxiety, and mood* Why this five minute breathing exercise may work better as you get older* How to build breathwork into your day without sitting in a quiet roomDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/sip-sip-sigh-could-three-words-changeCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  What If You Could Be Thin on the Outside and Sick on the Inside and Never Know It? 03.08.2026 29min

  Your scale cannot tell you how much visceral fat you’re carrying, and after 45, that’s the number that actually predicts your metabolic health. Two people can share the exact same BMI and face completely different risks.In this episode of The Habit Healers Podcast, I walk you through the three numbers that matter more than your weight: body fat percentage, body fat in pounds, and visceral fat. I explain why BMI misses so much, what researchers mean by “thin outside, fat inside,” and why sarcopenic obesity, the slow trade of muscle for fat, is the most dangerous body composition pattern for adults in midlife. We also get into what changes during menopause, when women accumulate significantly more intra-abdominal fat, and the parallel shift men experience as testosterone declines.Then I get practical. I cover how to measure your waist correctly, what waist-to-height ratio tells you, when a DEXA scan is worth it, and which home body composition scales actually held up under peer review.What you’ll learn:* Why body fat percentage predicts mortality better than BMI* How to measure waist circumference and waist-to-height ratio at home* Why visceral fat around your liver behaves so differently from subcutaneous fat* What menopause and declining testosterone do to fat distribution after 45* The seven evidence-based levers for reducing visceral fat, including aerobic exercise, resistance training, sleep, protein, and soluble fiber* Why sleep loss may be the most underrated driver of belly fatDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-where-your-fat-lives-mattersCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

  If you have ever wondered about that ridge on your nail, read this. 02.08.2026 22min

  What your nails say about your health is not an old wives’ tale. Your fingernails are a six month record of what your body has been through, and your skin is a much longer one. In this episode I show you how to read both.I walk you through the nail changes that actually mean something and the ones that don’t. The horizontal grooves called Beau’s lines, which mark the week you were sick months ago. Spoon shaped nails and what they suggest about iron deficiency anemia. Brittle nails, splitting, and peeling, and the protein, iron, and zinc gaps that often sit underneath them. Why white spots on nails are almost never a calcium deficiency. Then we move to the skin on your hands and forearms, the easy bruising and thin, fragile skin that dermatologists call actinic purpura, and the two habits that do the most to slow it down: daily broad spectrum sun protection and steady vitamin C for collagen production. I also give you the findings that belong on a call your doctor now list, because a few of them do.What you’ll learn:* How to read Beau’s lines and date a past illness on your own nails* What spoon shaped and pale nails suggest about iron deficiency and when to ask for ferritin testing* Why brittle nails respond to protein, iron, and zinc, and why biotin supplements can skew your lab results* What causes easy bruising and thin skin on the hands and forearms, and how to slow it* How your body makes collagen, and why vitamin C rich plants matter more than a powder* The nail and skin changes that need a doctor’s appointment, not a wait and seeDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/if-you-have-ever-wondered-about-thatCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
