If heart disease runs in your family, does changing what you eat even matter? In this episode of The Habit Healers Podcast, I share my own family history of early heart attacks and walk through what the research says about genetics, LDL cholesterol, and lifestyle, including a 2026 diet trial in people with familial hypercholesterolemia and a study of more than 51,000 adults. I’m Dr. Laurie Marbas, a lifestyle medicine physician, and this question is personal for me. My father had his first heart attack at 38, and my grandfather died of one at 46. So I take you back to the Dallas laboratory where two physicians discovered the LDL receptor and explained why inherited high cholesterol can start damaging arteries in childhood. Then we look at what happened when adults with a confirmed genetic cholesterol disorder switched to a plant-rich diet, why their results were encouraging and still not enough, and what that means if you already eat well or take medication. I’ll give you the single food swap that does the most to lower LDL cholesterol naturally, a realistic way to fit movement into your day, and the questions to ask your clinician about lipoprotein(a), a coronary calcium score, and heart attack prevention when your family history is the reason you’re worried. What you’ll learn: * How the discovery of the LDL receptor explains why familial hypercholesterolemia raises risk so early * What a plant-based diet did to LDL cholesterol in adults with an inherited cholesterol disorder, and why an 18% drop still needed treatment * Why a favorable lifestyle was linked to 46% fewer coronary events even in the highest genetic risk group * The fat swap and fiber changes that help lower cholesterol naturally * When to ask about lipoprotein(a) testing, a coronary calcium scan, and an LDL of 190 or higher * How to use the Family Heart Health Worksheet to prepare for your next visit Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/if-heart-disease-runs-in-your-family Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Is a blood sugar spike above 140 after eating actually a problem if you don’t have diabetes? If you wear a continuous glucose monitor (CGM) and feel a little sting every time the line climbs, this episode is for you. Welcome to The Habit Healers Podcast. I’m Dr. Laurie Marbas, a board-certified lifestyle medicine physician, and today I’m untangling one of the most misunderstood numbers in metabolic health. The 140 mg/dL cutoff comes from the oral glucose tolerance test, a very specific lab test with very specific conditions. It was never meant to grade your CGM reading forty minutes after lunch. I walk you through what a normal blood sugar range for non-diabetics really looks like, including a study where healthy people without diabetes or obesity still spent about half an hour a day above 140. We talk about why a single post-meal glucose reading can’t tell you whether sugar just arrived or has been sitting there for hours, using an airport baggage carousel to make it click. Then we get into what does matter: repeated elevations, your fasting blood sugar, your A1C, and a newer study linking more time above 140 with later diagnoses like prediabetes and high blood fats. Finally, I explain why blood sugar targets for people with diabetes are different, and why “just stay under the number” misses the danger of going too low. What you’ll learn: * Where the 140 blood sugar rule actually comes from, and why it doesn’t apply to every CGM reading * What normal blood sugar spikes after eating look like in healthy people without diabetes * Why a single glucose reading can’t show insulin resistance or metabolic health on its own * The lab categories for fasting glucose, A1C, and the glucose tolerance test, and what they mean * When repeated high glucose readings deserve attention and a conversation with your clinician * How blood sugar targets differ if you have diabetes or are pregnant Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/does-your-blood-sugar-really-need Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Functional fitness for older adults is really about one question: what do you want to keep doing on your own? In this episode of The Habit Healers Podcast, I walk you through ten everyday activities of daily living, from getting out of bed to carrying groceries home, and the simple strength, balance, and mobility exercises for seniors that protect each one. I’m Dr. Laurie Marbas, a lifestyle medicine physician, and what I see in my practice is that “get more exercise” rarely sticks because it’s too vague. So we get specific. I share what the LIFE study found when researchers followed over 1,600 inactive adults in their seventies and eighties, and why preserving walking ability is only part of healthy aging and staying independent. Then we go task by task: sit-to-stand practice for the toilet, supported step-ups for stairs and curbs, wall slides for reaching a cupboard, grip work for opening jars, and a walking progression you can start at two minutes. You’ll also hear how the LiFE trial reduced falls in older adults by building balance and strength training into ordinary routines, and how habit stacking, attaching a practice to breakfast or getting dressed, makes fall prevention exercise something you actually remember to do. What you’ll learn: * Ten everyday activities that support independent living and the movement each one requires * Simple strength and balance exercises for seniors you can do at home with a chair, counter, or wall * What the LIFE study tells us about exercise and mobility after seventy * How to build fall prevention into daily routines the way the LiFE trial did * When to use adaptations like a raised toilet seat, sock aid, or reacher while you build strength * How to progress safely from small repetitions toward your weekly exercise targets Dr. Marbas Substack Articles: https://drlauriemarbas.substack.com/p/10-ways-to-protect-your-independence Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Why am I hungry after a smoothie? If your healthy breakfast smoothie leaves you standing in front of the pantry an hour later, this episode of The Habit Healers Podcast is for you. I’m Dr. Laurie Marbas, and today I’m digging into the science of satiety: why liquid calories don’t keep you full the way solid food does, and how to build a filling breakfast that actually lasts until lunch. Most people blame the blender for destroying fiber. It doesn’t. So I take you back 200 years to a surgeon who could watch digestion happen inside a living stomach, then walk through the modern research on whole fruit versus smoothies, how fast juice and puree leave the stomach, and why a thick 100-calorie shake felt fuller than a thin 500-calorie one. We’ll talk about how your expectations change your appetite, what happened when people added liquid or solid calories to their diet for weeks, and where a high protein breakfast shake fits in. Then I give you four practical changes, a simple protein smoothie recipe, and a ten-morning test to find the breakfast that keeps you satisfied. What you’ll learn: * Why blending doesn’t destroy fiber, and what really changes when you drink a smoothie instead of eating a meal * How gastric emptying and food thickness shape hunger and fullness * Why eating whole fruit before your smoothie can reduce how much you eat at your next meal * How eating slowly and making your smoothie thicker can help you stay full longer * How much protein a filling breakfast needs and easy ways to get there * A ten-morning comparison worksheet to test one change and keep what works Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/your-smoothie-was-breakfast-why-are Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

How to Read a Medical Study and Actually Decide: Number Needed to Treat, the 10-Minute Triage, and Your Values Your doctor says a new treatment looks promising. Before you say yes, there is one number you should ask for: the Number Needed to Treat. In this episode of The Habit Healers Podcast, I’m walking you through how to read a medical study in ten minutes or less and turn the results into a real decision about your own health. I’m Dr. Laurie Marbas, and this is the final piece of our series on evidence-based medicine. We talk about why a treatment that “reduces risk by 20 percent” can still leave 99 out of 100 people with no benefit at all, and why the same Number Needed to Treat that makes a cheap aspirin reasonable makes a six-week surgical recovery a bad trade. Then I give you the five-checkpoint triage I use to sort a strong study from a weak one: the question, the design, the validity, the importance, and whether the people in the study are anything like you. And we finish with the part most people skip, which is that evidence-based medicine rests on three legs, not one. Best evidence, clinical expertise, and your own values. A treatment can be proven and still be the wrong choice for the life you want. What you’ll learn: * How to calculate the Number Needed to Treat and decide whether it is worth the cost * Why relative risk reduction makes small benefits look enormous * The 10-minute triage for evaluating a study without reading all 20 pages * Red flags in study design: no blinding, no randomization, high dropout rates * Why a statistically significant result can still be clinically meaningless * How to weigh treatment options against what actually matters to you Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/how-to-know-if-a-treatment-is-actually Check 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 reverse prediabetes naturally and lower your fasting blood sugar without medication? One of my Substack readers went from a fasting glucose of 116 to 91 in four months using six small daily habits, and I’m walking you through every one of them. If you’ve seen a fasting blood sugar reading land somewhere in the prediabetic range of 100 to 125, you already know that particular kind of quiet panic. Most people respond by trying to change everything at once, and most of them quit within three weeks. In this episode I share the story of a 64-year-old reader who did the opposite. She built a system so small and so portable she could run it in a hotel room, at a holiday dinner, or on a Tuesday in February. We talk about what’s actually happening in your body when insulin resistance starts to build, why your muscles are the largest glucose disposal system you have, and how a habit that takes 45 seconds can pull sugar out of your blood without insulin at all. What you’ll learn in this episode: * What a fasting blood sugar of 116 really means and why the prediabetic range is a warning, not a verdict * How walking after meals and simple movement activate GLUT4 transporters to lower post-meal blood sugar spikes * Why protein at every meal flattens your glucose curve * What the Arizona State research on apple cider vinegar and blood sugar actually found * How berberine activates AMPK, and why you should talk to your doctor first * Why three meals a day with no snacking improves insulin sensitivity overnight Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/she-reversed-prediabetes-with-6-habits Check 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 earliest signs of Parkinson’s disease show up in your gut, years before the first tremor? In this episode of The Habit Healers Podcast, I walk through what the research on the gut brain connection, diet, exercise, and sleep is telling us about how Parkinson’s actually begins. I’m Dr. Laurie Marbas, a board certified lifestyle medicine physician, and this is one of those topics where the science has quietly shifted underneath us. We’ll look at why constipation, loss of smell, and acting out dreams can precede a diagnosis by decades, what alpha-synuclein and mitochondrial stress have to do with it, and why the neurons hit hardest by this disease are the most energy hungry cells you have. Then we get practical. I’ll share why Mediterranean style and plant forward eating patterns keep showing lower Parkinson’s risk and slower progression, what happened in the high intensity exercise trials, how deep sleep clears metabolic waste from your brain, and which environmental toxins are worth taking seriously. What you’ll learn: * Why the gut microbiome and intestinal inflammation may be where Parkinson’s disease starts * How a Mediterranean, fiber rich, plant based diet supports brain health and lowers inflammation naturally * What high intensity exercise did to motor symptoms in people with early Parkinson’s * Why sleep quality drives the brain’s overnight cleaning system * How chronic stress and cortisol worsen Parkinson’s symptoms day to day * Which pesticides and solvents are linked to higher Parkinson’s risk Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/why-do-the-earliest-signs-of-parkinsons Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Does alcohol cause cancer, and does quitting actually lower your risk? Most women have never been given a straight answer about alcohol and breast cancer risk, so today I want to give you one, including the study finding that made quitting look like the wrong move. In this episode of The Habit Healers Podcast, I’m Dr. Laurie Marbas, and we’re walking through what the research on alcohol and cancer risk in women really shows. I explain why people who stopped drinking appeared to have higher cancer odds in the first two years, and why that number is measuring who quits rather than what quitting does. We look at what the evidence says about estrogen receptor positive breast cancer, why no level of drinking has been shown to carry zero added risk, and why switching to red wine does not solve the problem. Then I give you something practical: how to calibrate your own pour, how to count a week in grams instead of glasses, and how to set a target you can actually keep. If you have been sober curious, mindful drinking, or just wondering whether your nightly glass of wine counts, this one is for you. What you’ll learn: * Why the first two years after people quit drinking look backwards in the data * What the research shows about alcohol and estrogen receptor positive breast cancer * Why a standard drink is 14 grams, and why your usual pour is probably more * How to run a seven day pour count and find your real baseline * What changed in one month of no alcohol: blood pressure, insulin resistance, liver enzymes * The withdrawal warning signs that mean you should call your doctor before cutting back Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/alcohol-raises-cancer-risk-if-youve Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Why can’t you stick to an exercise routine? It may have nothing to do with discipline. In this episode of The Habit Healers Podcast, I explain the research finding that best predicts exercise adherence, and it’s not your trainer, your program, or your willpower. It’s how the workout feels while you’re doing it. I’m Dr. Laurie Marbas, and I want to walk you through what happens in your body when exercise intensity crosses a boundary called the ventilatory threshold, the point where effort turns into distress and your brain quietly files the whole experience under “avoid.” Below that line, almost everyone feels neutral to positive during movement. Above it, almost nobody does. We also look at the diet research that shows the same pattern, where the best predictor of weight loss wasn’t which plan people chose but how consistently they could live with it. Then I give you the one habit to start tomorrow morning, and it’s simpler than anything you’ve been sold. What you’ll learn: * Why in-the-moment enjoyment predicts exercise adherence better than post-workout mood * What the ventilatory threshold is and why crossing it makes workouts feel like suffering * How to use the talk test to find your sustainable exercise intensity * Why moderate-intensity exercise you enjoy beats high-intensity exercise you tolerate over a year * What diet adherence research reveals about sustainable habits and weight loss * How to build a walking or movement habit that actually lasts Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/the-real-reason-your-exercise-habit Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Your fitness tracker, your continuous glucose monitor, and your home blood pressure cuff are all giving you real numbers. The problem is that most of those numbers are noise, and reacting to them can quietly make your health worse. In this episode I walk you through a hundred-year-old method that came out of a telephone factory, not a clinic, and show you how to use it on your own body. We talk about the three ways your health data misleads you: regression to the mean, confirmation bias, and the multiple testing problem that happens when you watch two dozen metrics at once. Then I give you the four-week N-of-1 self-experiment structure that clinical researchers use with individual patients: a baseline week, alternating intervention and control weeks, one variable at a time, and a decision threshold you set before you start. Finally we go through five metrics worth tracking and exactly how much change counts as real for each one. What you’ll learn in this episode: * Why adjusting your routine after every bad reading adds variation instead of removing it * How to calculate your personal baseline before testing any intervention * The A-B-A-B design that separates a real effect from normal day to day fluctuation * Decision thresholds for steps per day, sleep duration and regularity, resting heart rate, home blood pressure, and post-meal glucose * Why sleep regularity may predict risk more strongly than sleep duration * Simple sample experiments you can run this month, including post-meal walking and nitrate-rich leafy greens Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/how-do-you-know-if-your-new-habit Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Is exercising only on the weekend enough? If you sit at a desk all week and cram your workouts into Saturday and Sunday, the research on weekend warrior exercise is better news than you think. In this episode of The Habit Healers Podcast, I walk you through what nearly 93,000 adults wearing movement trackers actually showed us about how much exercise you need per week, and why the total may matter more than the schedule. I’m Dr. Laurie Marbas, board-certified lifestyle medicine physician, and I want to untangle the three separate worries hiding inside one question. The first is whether one or two days of moderate to vigorous physical activity can carry a whole week. The second is prolonged sitting, which is its own health risk and something your Saturday workout cannot undo for you. The third is the injury and soreness risk that comes from going from nothing to a lot in one session. We talk about the 150 minutes of exercise per week target, how to use the talk test to know you’re at moderate intensity without a watch, why strength training twice a week is enough for most people starting out, and how to ease in so delayed onset muscle soreness doesn’t derail you. What you’ll learn: * Why the weekend warrior exercise pattern held up against spreading movement across the week * How to hit 150 to 300 minutes of moderate activity per week on a packed schedule * The talk test for checking moderate intensity exercise without a tracker * Why breaking up prolonged sitting with short walking breaks lowers blood sugar * How to build strength training for beginners into two days a week * A four-week ramp that reduces soreness and injury risk Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/is-it-bad-to-cram-a-whole-week-of Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Is sitting too much really the problem, or is it the chair? In this episode I explore the surprising science of floor sitting, sitting disease, and why your standing desk may not be protecting you the way you think. I share what researchers found when they studied the Hadza, a hunter-gatherer population in Tanzania who rest nearly ten hours a day, as much as office workers in the US, yet remain metabolically healthy. The difference is not how long they rest, it is how they rest: squatting, kneeling, and constantly changing positions in ways that keep muscles gently active. I also walk you through the sitting-rising test, one of the strongest functional predictors of longevity and independence, and share my complete twelve-week Floor Living Protocol so you can rebuild hip mobility, core strength, balance, and the ability to get up from the floor with confidence, no matter your starting point. If you have been worried about the health effects of prolonged sitting, back pain, stiffness, or fall prevention as you age, this conversation is for you. What you’ll learn: * Why sitting disease may actually be a disease of the chair, not of rest itself * What Hadza resting postures reveal about muscle activity, squatting, and metabolic health * Why standing desks trade one static posture for another * How the sitting-rising test predicts longevity and independence * My twelve-week Floor Living Protocol for hip mobility, core strength, and balance * How floor-rise training improves fall recovery, even in your seventies Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-sitting-disease-has-nothing Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Why is your blood sugar high when you didn’t eat anything extra? If stress and cortisol are spiking your glucose, the answer may come down to one thing nobody talks about: timing. In this episode of The Habit Healers Podcast, I’m Dr. Laurie Marbas, and I’m unpacking the strange, specific way stress hormones raise blood sugar, and why the same bad phone call can move your numbers forty points one afternoon and do nothing the next morning. I’ll walk you through what cortisol and adrenaline actually do inside your body, using a story about a bank you will never forget. You’ll learn why stress on an empty stomach barely touches your glucose, why stress after a meal keeps it elevated far longer, and why carbohydrates can actually make your cortisol response bigger. Then we get practical: what stress management did to A1c in a year-long trial, where mindfulness helps and where it doesn’t, and the research on walking after eating that gives you a way through the wall insulin resistance puts up. What you’ll learn: * How cortisol and blood sugar are connected, and why stress raises glucose without food * Why unexplained blood sugar spikes often trace back to when stress hit, not what you ate * The fasting versus fed research that changes how you think about stress and glucose * Why walking after eating lowers blood sugar, and why walking before a meal doesn’t * The exact post-meal walk timing the trials used: 15 to 20 minutes, starting within 30 minutes What stress management training did to A1c in people with type 2 diabetes Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/when-does-stress-actually-raise-your Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Tired all the time but your bloodwork keeps coming back normal? In this episode, I explain iron deficiency without anemia, the hidden gap between a normal complete blood count and low ferritin that leaves so many women exhausted with no answers. I’m Dr. Laurie Marbas, and on The Habit Healers Podcast today, I walk you through why a standard blood count only catches iron deficiency at its final stage, and why symptoms like unexplained fatigue, hair loss, restless legs at night, and a heart rate that climbs too high on easy walks can show up long before anemia ever does. I’ll show you the ferritin test most doctors never order, why the “normal” threshold was set decades ago to answer a different question, and the research suggesting your body starts compensating at levels your lab report still calls fine. Then I’ll give you my complete Low Iron Protocol: the four blood tests to request on one draw, how to take iron supplements correctly, why alternate-day dosing beats daily dosing, and when to stop. What you’ll learn: * Why a normal complete blood count can miss iron deficiency without anemia * The ferritin level where fatigue, hair thinning, and restless legs can begin * The four blood tests to request, including the one that tells you whether to trust your ferritin * How to take iron supplements for maximum absorption, and what blocks it * Why every-other-day iron dosing works better with fewer side effects * The three reasons iron runs low, and why finding yours matters Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/are-you-tired-losing-hair-or-unable Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Bladder leaks are one of the most common problems women quietly live with, and one of the least talked about. If you leak urine when you laugh, cough, sneeze, or exercise, or a sudden, hard-to-put-off urge sends you racing for the bathroom, this episode of The Habit Healers Podcast is for you. I’m Dr. Laurie Marbas, and today I’m walking you through the two main patterns behind urinary incontinence in women: stress incontinence, where pressure from a cough or a laugh triggers the leak, and urge incontinence, the pattern behind what many people know as overactive bladder. They can look identical by the time you’re changing your clothes, but they start in very different places, and that difference shapes which treatment your doctor should consider first. We’ll talk about why “just do Kegels” is incomplete advice, what pelvic floor exercises actually did in randomized trials, how bladder training really works, and what mixed incontinence means when both patterns show up in the same week. Then I’ll give you the Leak Pattern Decoder, a simple three-day bladder diary that captures what happened in the seconds before each leak, so you can bring your doctor a pattern instead of a guess. What you’ll learn: * The difference between stress incontinence and urge incontinence, and why it matters * What pelvic floor exercises and Kegels can and cannot fix * How bladder training for overactive bladder actually works * How to keep a three-day bladder diary your doctor can use * The warning signs that mean you should see your doctor first Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-happened-right-before-your-bladder Check 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 actually slow biological aging with small daily habits? New research on epigenetic clocks says yes, and the effect sizes might surprise you, because they look tiny until you run them forward over twenty-five years. In this episode of The Habit Healers Podcast, I’m Dr. Laurie Marbas, and I’m breaking down three recent clinical trials that measured biological age and pace of aging in real people. One found that a daily multivitamin slowed epigenetic aging by about four months over two years. Another showed that omega-3, vitamin D, and simple home exercise stacked together outperformed any single intervention. And a caloric restriction trial found that eating about twelve percent less each day slowed the pace of aging by two to three percent, a shift researchers compared to the mortality benefit of quitting smoking. I’ll also share the deposit almost nobody counts: social connection, and why isolation shows up in the molecular markers of aging, especially for men. Then I’ll walk you through a five-part biological aging audit covering movement, nutrition, dietary quality, connection, and sleep, so you know exactly where your highest-return habit change is hiding. What you’ll learn: * How epigenetic clocks measure your biological age and pace of aging from a blood test * What the multivitamin, omega-3, and caloric restriction trials actually found * Why stacking small healthy aging habits beats one dramatic intervention * How social connection and loneliness affect biological aging * A five-category audit to slow aging naturally and protect your healthspan Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-your-body-earns-compound Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

The moment that got me was when Chef Martin Oswald took a plain batch of hummus and turned it into a curry sauce. He loosened it with a little liquid, added yellow curry, fresh ginger, and a small amount of soy sauce, then folded in roasted vegetables he had already cooked. Minutes earlier, that same hummus had been spread on rye bread. Now it was doing a completely different job. This was Martin’s answer to the meal-prep photos we all see online. You know the ones. Rows of perfectly packed containers are lined up across the refrigerator, and the whole project looks as if it took all afternoon. His alternative comes straight from a restaurant kitchen. Prepare a few flexible components, keep them separate, and decide later what they will become. If you missed the first step in this series, Martin gathered it in How to Start Eating Healthy . That conversation was about finding the first change worth making. This one was about making that change easier to live with. Prep components instead of finished meals Martin began with four basics he had made ahead of time. There was cooked quinoa, a large tray of roasted vegetables, hummus, and a basil pesto made with silken tofu. None of them was a complete meal. That was the advantage. The quinoa could land in a soup, stir-fry, or bowl. The roasted tray held eggplant, peppers, mushrooms, broccoli, cauliflower, tomatoes, potatoes, and tempeh. The hummus could stay thick enough for bread or become a light sauce. The pesto could lead one dish and sit quietly in the background of another. You don’t have to surrender an entire Sunday to do this. Roast one tray, cook one grain, make one bean puree, and choose one sauce you enjoy. The decisions get smaller during the week because the longer jobs are already done. Use the knife to manage the cooking time One of Martin’s best lessons happened before the tray went into the oven. Vegetables do not all soften at the same rate, so he changed the size of the pieces. Ingredients that needed more time, including the potatoes and eggplant, were cut smaller. That helped the whole tray finish together. His demonstration tray roasted for about 18 minutes at 425°F, or 220°C. Martin emphasized that the timing depends on how large you cut the pieces. A knife can solve part of the timing problem before the oven ever has to. Let one base do more than one job Then the components began changing shape. First, Martin spread hummus on rye bread and added roasted pepper, whole chickpeas, red pepper flakes, and a few olives. He served it as a simple lunch with salad. Next, he chopped some of the roasted vegetables into vegetable stock, added quinoa, and finished the bowl with a spoonful of basil pesto . A tray of vegetables had become soup without starting again from raw ingredients. For the stir-fry, he turned the hummus into that yellow curry sauce, added ginger and soy sauce, then warmed the roasted vegetables through it. He finished with a small amount of basil pesto. It sounded Italian on its own, but here it worked as a background herb flavor. Finally, he arranged the same components in a bowl with greens, potatoes, tomato, tempeh, hummus, and fruit. It looked as though he had cooked for hours. Martin called it cheating. I had to correct him. “No, you’re efficient.” Change the flavor before flavor fatigue arrives The separation matters because one large batch can become tiresome when every bite tastes the same. Martin called this flavor fatigue. His answer was to use the strong flavors strategically. A spoonful of pesto finished the soup. Curry and ginger pulled the vegetables in another direction. Red pepper flakes and olives gave the bread its own flavor. The base ingredients stayed familiar while the meal changed around them. Martin also gave us permission to substitute what we already have. Farro, brown rice, black rice, or lentils could stand in for quinoa. The components could become a taco, a rice plate, or even a pizza. You are preparing possibilities, not locking yourself into a menu. That may be the most useful way to think about meal prep. Do enough work ahead of time to make tomorrow easier, then leave yourself room to want something different.

If you struggle with chronic insomnia, wake up at 3 AM with your mind racing, or feel tired but wired no matter how perfect your sleep hygiene is, this episode is for you. I’m Dr. Laurie Marbas, and on today’s episode of The Habit Healers Podcast, I’m walking you through what the research actually says about why some people can’t sleep, and the surprising first-line treatment that works better than sleeping pills. Here’s the part most people miss: chronic insomnia usually isn’t a broken sleep drive. It’s a wake system stuck in overdrive, a state researchers call hyperarousal. And many of the things we do to fix it, like napping, sleeping in, and going to bed early, are the exact behaviors that keep insomnia locked in place. I’ll explain the 3P Model of how insomnia develops, the conditions that masquerade as insomnia, including restless legs syndrome, sleep apnea, and circadian rhythm disorders, and why Cognitive Behavioral Therapy for Insomnia (CBT-I) is now the gold standard treatment. Then I’ll give you a simple protocol you can start tonight. What you’ll learn: * Why chronic insomnia is a disorder of hyperarousal, not a lost ability to sleep * The 3P Model: how a few bad nights become chronic insomnia disorder * Red flags for sleep apnea, restless legs syndrome, and circadian rhythm disorders * How CBT-I and sleep restriction therapy rebuild your natural sleep drive * The Stop Trying Sleep Protocol: the quarter-hour rule, anchor wake time, light exposure, and scheduled worry time Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/why-is-it-that-the-harder-you-try C heck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe

Daylight saving time is not just an annoying clock change. The spring forward transition disrupts your circadian rhythm in ways that measurably increase heart attack risk, worsen blood sugar and insulin sensitivity, and cause real sleep deprivation that can take days to recover from. In this episode, I break down the three clocks running inside your body: the central clock in your brain, the peripheral clocks in your liver, pancreas, and heart, and the social clock your schedule imposes on you. When those clocks fall out of sync, whether from the time change, jet lag, or shift work, your metabolism and cardiovascular health pay the price. I also explain social jet lag, why night owls carry higher diabetes risk, and why roughly 20 medical organizations now support permanent standard time. Then I give you my complete clock reset protocol: morning light exposure, meal timing, gradual sleep shifts, and the research on low-dose melatonin and creatine for circadian disruption. What you’ll learn: * Why the spring time change increases heart attack risk and fatal traffic accidents * How circadian rhythm disruption affects blood sugar, insulin sensitivity, and diabetes risk * What social jet lag is and how to know if you have it * A day-by-day plan to adjust to daylight saving time or time zone travel * How to use morning light exposure and meal timing to reset your internal clock * When and how to use melatonin as a timing signal, not a sleeping pill Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/are-you-part-of-the-largest-uncontrolled Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
