In this episode, I’m asking a question that sounds a little wild until you start looking at the evidence: are animals the most powerful medicine we have? And I’m not talking about magic—I’m talking about biology, behavior, and the quiet ways other species seem to “read” us better than we read ourselves.

I start with Oscar, the hospice cat who stunned a nursing home staff by repeatedly curling up beside residents just hours before they died. From there, I zoom out into the bigger pattern: the silent, constant conversation between human bodies and animal senses—smell, breath, posture, rhythm, routine. I explore how we communicate across species without words, from the way dogs (and even cats) follow our pointing and gaze, to the oxytocin loop that kicks in when a dog holds eye contact, shifting both of us toward calm and connection.

Then I go deeper into the long history of partnership—wolves at ancient campfires turning into dogs, cats showing up where grain attracted mice, and how co-evolution didn’t just change them… it shaped us. I talk about attachment, why a dog can feel like a “secure base” the way a parent does for a child, and what research suggests about stress, cortisol, blood pressure, loneliness, and even immune training in kids raised around pets.

We also get practical: what happens when animals become part of the treatment plan—therapy dogs on hospital floors, service dogs helping veterans with PTSD, animals acting as bridges for kids with autism, and horses used in rehab. And yes, I go to the edge of the map: sea lions that may keep someone afloat, elephants that appear to mourn, a pig that saved a woman’s life, and dogs that can sometimes detect seizures, low blood sugar, or even cancer.

But I don’t skip the fine print. I talk about zoonotic risks, bites, hospital infection control, and the ethical line between partnership and exploitation—because if animals are part of health, their wellbeing has to be part of the equation too.

By the end, I’m left with the real question: if animals already function like quiet, unpaid members of the healthcare team… what would it look like to treat that bond as something we plan for—on purpose?

In this episode of the Habit Healers podcast, Dr. Laurie welcomes Dr. Jud Brewer to discuss his Substack article, "The Generosity Paradox." Dr. Brewer explores the complexities of generosity, emphasizing that it is not as straightforward as many believe. He delves into the emotional aspects tied to giving, such as guilt and giver's remorse, and highlights that generosity encompasses more than just monetary donations. The conversation introduces three different types of generosity, starting with the "transactional loop," where giving is linked to an expectation of receiving something in return. Join us for a thought-provoking discussion that unpacks the deeper components of generosity and its impact on our lives.Link to Dr. Jud's article: https://judbrewer.substack.com/p/the-generosity-paradox-why-your-brainDr. Marbas Substack: https://drlauriemarbas.substack.com/A Big Thank You To Our Sponsors:If you want the best supplement to help you on your plant-based journey, you have to try Complement: https://lovecomplement.com/?aff=62

If you’ve ever felt like you have to choose between running for your heart or lifting for strength, I’m here to tell you that’s the wrong question. In this episode, I walk through the simple truth the research keeps repeating: cardio and resistance training do different jobs, and if you want your workouts to fight aging—not just burn calories—you need both.

I’ll explain why cardio is great at supporting your heart and metabolism, but why lifting is the lever that protects the stuff that actually makes aging harder: muscle, bone density, and the ability to keep moving well. We’ll talk about bones in particular—because they don’t respond to wishful thinking. They respond to force. If you want stronger hips and spine over time, you have to put your body under a load that feels heavy.

Then I get into the real reason most of us skip strength work: not laziness—friction. The tiny barriers (drive time, waiting for equipment, “I’ll do it later”) quietly kill the habit. So I share the strategy that actually works: habit stacking—bolting lifting onto the cardio you already do, so it becomes automatic instead of optional.

I’ll also give you my favorite “zero commute” tools that take up almost no space—a doorstop kettlebell, a weighted vest, a sandbag—and exactly what “heavy” means in real life (hint: 8–12 reps, with the last two feeling brutal). Because the bottom line is this: your heart needs movement… but your bones need battle.Dr. Marbas Substack: https://drlauriemarbas.substack.com/

Ever been called “lazy” even though you can spend hours building something brilliant when it grabs your attention? In this episode, I walk through why that disconnect is basically the signature of ADHD—and why ADHD isn’t really an attention deficit so much as an attention regulation problem.

I’ll break down what’s happening in the brain using a simple (and weirdly accurate) framework: the “Task Positive Network” (the boss that tries to get work done) versus the “Default Mode Network” (the chatterbox that daydreams, worries, and notices squirrels). For an ADHD brain, that office management system glitches—so you’re trying to do the worksheet while the radio is blaring inside your head. Then I’ll explain the “Lego paradox”: why dopamine can flip you into hyperfocus when something is interesting, and why boring tasks can feel physically painful.

We’ll also talk about why ADHD diagnoses have risen, why girls and adults have been historically missed, and what medication actually does (think: cognitive eyeglasses—not a personality eraser). But the heart of this episode is the practical part: the ADHD Standard Operating Procedure (SOP)—a four-phase system I use to “engineer” an ADHD-friendly life with less shame and more structure. I’ll introduce the one-time setup, the daily boot sequence, and the crucial If/Then logic tree—so when you drift, freeze, or overwhelm hits, you’re not relying on willpower… you’re following a script that works with your brain.Dr. Marbas Substack: https://drlauriemarbas.substack.com/

I get asked about fish oil all the time. And I understand why. One study says it saves lives. Another says it does nothing. Some people swear by it. Others call it useless. So in this episode, I wanted to slow everything down and ask a simpler, more honest question: do you actually need fish oil—and if you do, how much makes sense for you?

I walk through the trial that made omega-3s famous again, the one that showed real cardiovascular benefit with a high-dose, EPA-only prescription product—and then explain why other large trials, using different formulations, showed no benefit at all. This is where most of the confusion lives, and it turns out the details really matter.

We break down what omega-3s actually are (and why “fish oil” isn’t one thing), the differences between ALA, EPA, and DHA, and what they really do inside the body. I explain when omega-3s are essential, when they’re conditionally helpful, and when adding more likely won’t change anything.

I also talk about blood testing—what an Omega-3 Index can tell you, what it can’t, and how to use testing without over-interpreting it. We cover heart disease, triglycerides, pregnancy, brain health, mood, dry eyes, autoimmune conditions, plant-based diets, algae-based omega-3s, krill oil, and why supplement labels are often misleading.

And because this isn’t a wellness trend conversation, we also talk about risk—atrial fibrillation, bleeding, dose, and when omega-3s should be treated like a medication decision, not a harmless habit.

This episode isn’t about convincing you to take another supplement. It’s about helping you stop guessing. If you’ve ever stood in the supplement aisle—or stared at a lab result—wondering whether fish oil actually belongs in your life, this conversation will give you the framework to decide.Dr. Marbas Substack: https://drlauriemarbas.substack.com/

I want to talk about what no one tells you after you lose weight—what actually changes inside your body, and why keeping the weight off can feel so much harder than losing it in the first place.

In this episode, I walk through what I’ve learned from decades of metabolic research and clinical medicine: when you lose weight, your body doesn’t reset. It remembers. And biologically, it fights to return to where it was before.

We’ll unpack the science of adaptive thermogenesis—the quiet metabolic shift that makes your body burn fewer calories, move less, and slow down even when your habits haven’t changed. I explain how your muscles become more energy-efficient, why your thyroid output can drop, how spontaneous movement fades, and why two people at the same weight can have dramatically different metabolisms.

Then we go deeper into hunger—not as a feeling, but as a coordinated hormonal system. I break down what happens to leptin, ghrelin, GLP-1, and other appetite signals after weight loss, and why cravings get louder while fullness gets quieter. We also explore how the brain changes: food becomes more rewarding, hunger signals get amplified, and the part of the brain responsible for restraint gets less support.

This is why weight regain feels personal—even when it isn’t. Nothing about these changes is visible. All you feel is hunger, fatigue, and frustration. So most people blame themselves, again. But your body never stopped defending itself.

I also address one of the biggest questions I hear right now: what role do GLP-1 medications really play? What happens when you stop them? And how do you build a system underneath the medication so the progress doesn’t disappear when the drug does?

This episode isn’t about fear or failure. It’s about understanding the biology you’re working with—so you can stop fighting your body and start building a version of maintenance that your physiology can actually sustain.

If you’ve ever said, “I did everything right—why is this so hard?” this episode is for you.Dr. Marbas Substack: https://drlauriemarbas.substack.com/
