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

    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 cramps Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/why-your-calf-cramps-up-in-the-middle Check 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)

    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 doctor Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/6-evidence-based-ways-to-manage-gas Check 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

    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 strength Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/7-outcomes-worth-tracking-when-weight 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 Tonight’s Dinner Could Lower Tomorrow Morning’s Blood Sugar?

    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 tonight Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-tonights-dinner-could-lower 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 Mice Had Unlimited Food, No Predators, and No Disease. They All Died Anyway.

    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 functioning Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/the-mice-had-unlimited-food-no-predators 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 You Could Train Your Brain to Forget Less?

    Is your forgetfulness normal aging, or something more? 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 doctor Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-you-could-train-your-brain 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 Caramelize Onions Without a Single Drop of Oil?

    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 pan He 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 boil A 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 ghee The 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. I am live every Tuesday at 4 PM Pacific for ninety minutes, and you can bring me whatever question you have been sitting on. Everything lives inside The Habit Healers on Skool. Join us here.

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

    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 room Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/sip-sip-sigh-could-three-words-change Check out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
