Ep. 14: The Weight Loss “Bermuda Triangle”: Are You Stuck in It? — with Dr. Phyllis Pobee, MD
Why do so many women do everything ‘right’ and still can’t lose the weight — or watch it pile on after 30? In this episode, Dr. Regina Druz talks with Dr. Phyllis Pobee, a triple board-certified genetic weight-loss physician who lost 100 pounds herself once she understood her own DNA. Together they map the ‘Bermuda Triangle’ of weight: cortisol, thyroid, and estrogen — three interconnected hormone systems, each shaped by your genes, that can trap women in stubborn weight gain and belly fat. You’ll learn what a ‘cortisol carrier’ is, why thyroid problems often start upstream with stress, how shifting estrogen rewrites fat storage in perimenopause and menopause, why you shouldn’t rush onto hormone therapy or GLP-1 drugs without knowing your genetics, and how root-cause, personalized strategies can finally get women unstuck.

[00:00] Introduction & Meet Dr. Phyllis Pobee
Dr. Regina Druz (00:00): Welcome to Own Your Heart Health. I’m Dr. Regina Druz, your holistic cardiologist. This week we’ll dive into common heart health concerns, uncovering root causes and unpacking scientific discoveries and controversies. The information provided does not constitute medical advice. Please contact your healthcare practitioner before making any changes that may impact your health.
Dr. Regina Druz (00:30): Hi everyone — another wonderful Thursday, and another phenomenal guest. Part of my task on this podcast is to amplify the voices of physicians who’ve taken a different route to benefit their patients. I’m super excited to introduce Dr. Phyllis Pobee, a fellow physician in the integrative space who has done something really special — I’ll let her tell you about it herself.
Dr. Phyllis Pobee (01:00): Thank you so much for having me — it’s a pleasure. Anytime I can talk about genetics and genetic weight loss, I’m happy, because it completely transformed my life. Being an overweight physician brought me a ton of shame; I felt I wasn’t giving the best version of myself to my children, my husband, or my patients — and it truly wasn’t for lack of trying. A lot of women relate to that: we’ve tried every method out there. I even tried the cabbage-soup diet. It wasn’t until I delved deep into my own genetics that I realized I wasn’t to blame — there was a real reason I’d struggled my whole life — and once I had the right strategy, it transformed my mindset and my body, and I haven’t looked back.
[01:30] Her Story: Genetic Weight Loss & 100 Pounds
Dr. Regina Druz (01:30): Let’s unpack this, because there’s hardly a woman out there who isn’t wishing to lose some weight — especially after the holidays, heading into spring. Have you been overweight throughout your adult life, or did it sneak up after your babies and training?
Dr. Phyllis Pobee (02:30): I’ve been overweight my whole life — I remember being thirteen and already about 130 pounds. I worked at it constantly; my mother battled weight her whole life and exercised avidly, so I followed her lead and over-exercised. Even when I was a hundred pounds overweight, I was exercising morning and night. It was a huge surprise to learn I was what I call a cortisol carrier — so exercising like that was actually worsening my ability to lose weight. That showed itself most after my two kids. I could get away with it when I was younger, which is exactly why I now work with women over 30: it’s a whole different ballgame once you factor in the interplay of all these hormones.
[03:30] The Hormones That Sabotage Weight Loss After 30
Dr. Regina Druz (03:30): As a cardiologist, the old teaching was that women have a leg up on men because heart disease tends to come later, around menopause. Contemporary science disproves that — there’s a lot of asymptomatic disease in both. But something happens in women over 30 that plants the seeds of chronic disease: heart disease, hypertension, high cholesterol, diabetes, even breast cancer — seeds planted at an age when we feel invincible. What’s happening?
Dr. Phyllis Pobee (04:30): It comes down to understanding hormonal shifts. Estrogen significantly affects weight, energy, and fat storage, and as we hit 30 our estrogen begins to decline. Genetic variations — in metabolism genes like your CYP1 and COMT genes — actually predict how you’ll move through perimenopause and menopause, and can predispose women to hormone imbalances even before they get there. But when we say ‘hormones,’ we forget the stress hormones: chronic stress raises cortisol and promotes fat storage, especially around the midsection. I call those women cortisol carriers. And then there’s the master metabolism hormone, thyroid — variants like DIO2 affect how thyroid hormone converts, which can mean low energy, weight-loss resistance, and a push toward insulin resistance. Insulin, disrupted by variants like IRS1, is that knock at the door telling cells to take in glucose; when it’s impaired you get insulin resistance, weight gain, and energy crashes.
[05:00] Cortisol Carriers & the Stress Hormone
Dr. Regina Druz (05:00): In functional medicine we focus on the center of the matrix — the mental, emotional, and spiritual core — and a huge part of that is stress load and our ability to cope under it. So the body pushes on multiple levers, and how hard each lever gets pushed is genetically guided — but the initial variable that throws things out of balance is often that cortisol surge. How do you identify a cortisol carrier?
Dr. Phyllis Pobee (05:45): From the genetic standpoint we look at markers like the NR3C1 glucocorticoid-receptor gene — is there an issue with the receptor and how your body responds to the hormone? Women with certain variations experience prolonged cortisol elevation under stress; they don’t clear it. We have these receptors throughout the body, so once cortisol surges, it stays surged. Cortisol is great when you’re running from a bear, but if it doesn’t come back down through the day — or when you’re trying to sleep — your metabolism is severely affected and it promotes fat storage, particularly in the abdomen. That chronic elevation also impairs insulin sensitivity and drives inflammation, feeding more weight gain and fatigue; elevated cortisol has even been linked to poorer breast-cancer outcomes.
[09:00] Circadian Rhythm, Sleep & Clearing Cortisol
Dr. Phyllis Pobee (09:00): A lot of people think they can’t go to bed until they’re stuffed — and your cortisol hates that, because now it has to process a giant meal. I love the idea of eating when the sun is up and not having a huge meal when it’s down, so you follow your natural circadian rhythm. Cortisol should be highest in the morning and fall at night; when it’s out of whack, you end up in bed doom-scrolling, unable to sleep, and then you ask your doctor for a sleep pill when a few habit changes could get you sleeping — and burning fat — better.
Dr. Phyllis Pobee (10:30): I love that you tie it to circadian rhythm, because cortisol and melatonin are opposites — if cortisol is high, melatonin stays low and you can’t sleep. And there’s a strong link between sleep disruption and visceral, mid-body fat. To manage stress-related sleep disruption, the practical strategies matter: mindfulness or progressive muscle relaxation to lower cortisol, magnesium-rich foods like spinach and almonds, and adaptogens like ashwagandha, which has been shown to reduce cortisol and build stress resilience.
Dr. Regina Druz (14:00): Hi everyone, it’s Dr. Regina here. I know there are contradictory opinions about nutrition for heart health and longevity — the discussion gets heated and confusing. Some push low-fat, low-cholesterol; others are fans of a ketogenic diet; and there are many voices urging vegan or vegetarian eating. To cut through the clutter, my team and I created Holistic Heart University: on-demand courses, nutrition and lifestyle resources, and supplement guidance to make healthy choices for your heart easier to understand. I’m especially proud of our open office hours and the Q&A feature where you can put us in the hot seat.

[15:00] The Bermuda Triangle: Cortisol, Thyroid & Estrogen
Dr. Regina Druz (15:00): So some women are stuck in a kind of Bermuda Triangle — anchored by cortisol, estrogen dominance, and thyroid imbalance — where what used to work just disappears, and they can’t get out. To escape, you have to break the triangle apart. What I often see clinically is that women fixate on their reproductive hormones — reaching for bioidentical hormone replacement, which has its place — while bypassing this first step, the apex of the triangle: they aren’t even aware of their cortisol spikes.
Dr. Phyllis Pobee (16:00): Exactly. And wearables help here — a smartwatch or an Oura ring can show your heart-rate variability and stress curve, so you start to see which activities in your day push you into the stress zone. Then you can take what I call micro-breaks. For women whose receptors keep cortisol around because of those genetic variations, simple things matter most: a light-intensity walk, fresh air, and not reaching for a giant bowl of ice cream as a coping mechanism, because that brings its own stress. Variants in the CLOCK and PER3 circadian genes also influence sleep quality, and poor sleep raises ghrelin (hunger) and lowers leptin (satiety), driving overeating. So at the very least, prioritize a consistent sleep schedule, reduce blue light, and use calming routines before bed.
Dr. Regina Druz (20:00): I’d add: build a routine the rest of your household can follow, and limit not just blue light but the news itself before bed — it’s dynamic and upsetting, and it creates a self-sustaining cortisol spike even when your circadian rhythm is otherwise fine. Do you test cortisol with saliva or urine, or work mainly from genetics and clinical response?
Dr. Phyllis Pobee (20:45): Mainly clinical response based on genetics, with the option to send a saliva test for confirmed cortisol carriers. But I try not to get caught up in numbers — sometimes the scale hasn’t moved the way you want, yet you feel great and your clothes fit better. I look at the person, not just the lab markers: if your symptoms and sleep are better, that matters more to me.
[21:30] Thyroid: T4-to-T3, DIO2 & Looking Upstream
Dr. Regina Druz (21:30): Let’s take thyroid — and let’s clarify for listeners. The active thyroid hormone in the body, T3, is largely converted from a storage form, T4. So having ‘enough T4’ on labs isn’t the whole story.
Dr. Phyllis Pobee (22:30): Right — variants in DIO2 influence how much T4 converts to active T3. If that conversion is impaired, you don’t get the metabolic regulation you need, and reduced T3 means slower metabolism, weight gain, and fatigue. People hear ‘T3, T4’ and get lost, so I love that you clarified it: it’s not just about normal T4, it’s about whether the conversion to T3 is actually happening.
Dr. Regina Druz (23:30): And it’s like a switch, because in functional medicine we look upstream of thyroid — and what’s upstream is cortisol. When cortisol is high or won’t clear, the body can flip the fork in the road and make reverse T3, the ‘anti-hormone’ that blocks T3’s effects, so you burn nothing and store everything. That’s the essence of root-cause medicine — making sure the whole pathway works, not just dumping more product at the end.
Dr. Phyllis Pobee (25:00): Exactly. Sometimes we get caught up thinking that if we just add more at the end, we’ll get the result — instead of looking upstream. With a genetic program, I’m not just saying ‘you have a SNP here or there’; I’m connecting them so women see there’s a pattern, an intricate biochemical circuitry, and we can regulate some of it.
[26:00] Estrogen, Aromatase & Menopausal Weight Gain
Dr. Regina Druz (26:00): Now the loaded one — estrogen. Women tell me they gained ten pounds in six months and have no idea why. I went through it myself: never overweight, then perimenopause plus stress, and suddenly I saw numbers I hadn’t seen since pregnancy. What’s actually happening to these hormones as women get older?
Dr. Phyllis Pobee (27:30): Estrogen plays a critical role in body-fat distribution, metabolism, and weight regulation, and the genetic variations explain why women often say ‘I gained weight just like my mom.’ Take the aromatase gene, CYP19A1, which converts testosterone into estrogen: high-activity variants raise estrogen and promote fat storage in the hips, thighs, and lower belly, while low activity contributes to low estrogen, poor muscle tone, and more visceral fat. Then the receptors, ESR1 and ESR2, control how your body responds to estrogen — ESR1 variants are linked to higher fat storage and difficulty losing weight in menopause. And COMT, which clears estrogen in the liver: slow COMT leads to estrogen buildup, bloating, and fluid retention, while fast COMT breaks estrogen down too quickly, leading to low estrogen and worse menopausal symptoms.
Dr. Phyllis Pobee (30:00): So why the weight gain? As estrogen declines in menopause, fat shifts from the hips and thighs to the belly, and metabolism slows — so with variants in FTO, ADRB2, and ESR1, you store fat and gain weight on the exact same diet and routine that used to work. That’s what frustrates everyone.
Dr. Regina Druz (31:00): Let’s unpack the two receptor types. We’ve had these receptors our whole lives — so as hormones fluctuate, and we pass transiently through estrogen dominance early in menopause, is that dominance acting preferentially on one receptor over the other, and is that genetically driven?
Dr. Phyllis Pobee (31:45): Definitely — it’s the receptor that determines how estrogen plays out in your body. Knowing this before menopause lets you prepare. You can support estrogen detox with cruciferous vegetables — broccoli, cauliflower — fiber, or supplements like DIM; balance carbs and protein, because estrogen-sensitive women do better with moderate carbs and higher protein; do strength training to balance estrogen and preserve muscle; and manage stress, because high cortisol worsens estrogen-related weight gain. So don’t be too quick to hop on hormone therapy without understanding your genetics.
[34:00] Don’t Rush HRT: Know Your Genes First
Dr. Regina Druz (34:00): I’m so glad you said that, because I see a worrisome trend: a proliferation of direct-to-consumer hormone dispensaries handing out prescriptions without addressing the genetic and detox pathways or where someone stands on cortisol. If you’re a cortisol carrier and estrogen dominant, bioidentical hormones may not help — they may do the opposite — and that’s often exactly when these women land in cardiology with high blood pressure, abnormal lipids, and chest pain. Some physicians also bump up testosterone in menopausal women. Your thoughts?
Dr. Phyllis Pobee (35:30): I’ve seen benefits depending on the symptom — some women sleep better on testosterone — but keep in mind some of that testosterone converts to estrogen, so if you’re already estrogen-dominant, adding it can worsen your symptoms. I’m on the fence; since we’re usually dealing with weight, I focus more on clearing excess estrogen — detoxifying — especially in slow-COMT women.
Dr. Regina Druz (36:30): I tell my COMT patients: you’re a smart, sensitive, super-achiever — which also means you’re not breaking estrogen down well. And there are different set points from woman to woman: a level that’s right for one woman would make another feel terrible because she’d be estrogen-predominant. It’s a moving target.
[37:30] Your Genetic Avatars: The Ones to Know
Dr. Regina Druz (37:30): If you had to name the genetic variabilities every woman heading toward perimenopause should know about herself, what are the top few?
Dr. Phyllis Pobee (38:00): First, know if you’re a cortisol carrier — postmenopausal stress and high cortisol drive persistent belly fat and sugar cravings. Second, know if you’re a sugar shaper — more prone to insulin resistance, which worsens as estrogen falls. Third, know your dopamine — are you a dopamine driver? Many of us powered through life with low dopamine, then find ourselves always at the fridge, self-medicating with high-sugar food for a dopamine rush. And a fourth: MTHFR — I call these women fatigue fighters; they may need methylated B vitamins. Many cravings are really nutrient deficits: I used to crave chocolate intensely, and it was a magnesium deficiency, because today’s soil isn’t what it was 30 or 40 years ago. So you can be overfed but undernourished. These are the genetic avatars I describe in my book, Lean Genes — twelve avatars that become the story of you.
[42:00] GLP-1 Drugs: Helpful Tool or Missing the Root?
Dr. Regina Druz (42:00): In a previous show I talked about the three O’s sabotaging women’s weight loss — over-fasting, over-restricting carbs, and over-stressing. But someone will say, ‘Who cares — just give them Ozempic.’ You just gave me a universal heart-attack sign on camera, so for those listening on audio, go to YouTube. What do you think of weight-loss pharmacotherapy?
Dr. Phyllis Pobee (43:00): People like these drugs because they get rid of the food noise — but that’s telling a story. If you’re craving because of a nutrient deficiency, silencing the food noise doesn’t fix the underlying issue, the cortisol, or the hormone imbalance. And when you come off, you’ve slowed your metabolism and lost muscle, so you regain rapidly — as fat, not muscle — and end up worse metabolically than when you started. So I’m not a big proponent.
Dr. Regina Druz (44:00): I agree, though my use case in cardiology is a bit different — we use them to lower inflammation and reduce fat around the heart and its vessels. Semaglutide trials showed cardiac benefits that didn’t track one-to-one with weight loss, because of fat remodeling in those locations. But we typically use modified, microdosed regimens to mitigate side effects, built on a lifestyle foundation — because without that foundation, you can’t sustain success.
Dr. Regina Druz (45:30): Hi everyone, it’s Dr. Regina here. Many of my colleagues and I are seeing patients arrive with self-ordered blood tests. When this trend started, I thought it would help — who doesn’t want more access to their health data? But too often self-ordered labs lead to more confusion and frustration: patients come in with a pile of results and are no better off. That’s why we created HeartWell Toolkits — a curated collection of at-home blood and genetic markers focused on heart and brain health that gives you the data you need to make informed, actionable decisions.

[46:30] Epicardial Fat, Polygenic Scores & Working With Dr. Pobee
Dr. Regina Druz (46:30): You asked how the heart reacts to drastic weight loss. In humans we mostly have data in a specific group — heart failure with preserved ejection fraction, where the number looks fine, even too good, but the heart is thick and often wrapped in a layer of epicardial fat that squeezes it and even infiltrates the muscle, almost like cancer cells. With imaging and AI we can now quantify the fat around the heart and its vessels, and higher amounts track with worse outcomes — new and progressing atrial fibrillation, coronary microvascular dysfunction, and this ‘obesity-phenotype’ heart failure. Semaglutide and SGLT2 inhibitors have shown real benefit there. We just don’t yet know the long-term effect on heart muscle in people who don’t start with those big fat deposits.
Dr. Regina Druz (49:30): Fascinating. What’s your take on polygenic risk scores — pulling many variants together rather than single SNPs?
Dr. Phyllis Pobee (50:00): It all tells a story — some SNPs are protective, some are risk factors — so you can’t judge from a single snapshot. Pulling in more pieces strengthens our protocols and treatment plans, and we use that a lot. People often think one genetic test equals another, but they’re very different in the information they provide and how it’s assembled.
Dr. Regina Druz (51:30): Agreed — the essence of personalization is endo-phenotyping: finding the genetic connections that make sense and giving patients actionable steps that don’t waste their time and money. How do people work with you?
Dr. Phyllis Pobee (51:50): Head to geneticweightloss.com — you can get your questions answered, pick up my book Lean Genes, learn about the genetic avatars, and book a consultation. You can also find me on Instagram and YouTube at GeneLean360. I’d love to connect.
Dr. Regina Druz (52:30): You heard it here — I’m enjoying your book, Phyllis (I’m halfway through, I’ll admit). I love that you sort people into genetic phenotypes, because that’s true personalization: actionable, not magical — built block by block, but, as your own story shows, absolutely possible.

Frequently Asked Questions
What is a “cortisol carrier,” and why does it stall weight loss?
A ‘cortisol carrier’ is Dr. Pobee’s term for someone whose genetics — particularly variations in the NR3C1 glucocorticoid-receptor gene — cause prolonged cortisol elevation under stress. Normally cortisol should peak in the morning and fall at night, but in a cortisol carrier it stays elevated and doesn’t clear. Because cortisol receptors exist throughout the body, that sustained elevation slows metabolism, promotes fat storage (especially around the abdomen), impairs insulin sensitivity, and drives inflammation — a recipe for stubborn weight gain and fatigue. It also explains why intense, twice-a-day exercise can backfire for some people, as it did for Dr. Pobee herself. The practical fixes she suggests include stress-management techniques, magnesium-rich foods, adaptogens like ashwagandha, light walks, protected sleep, and limiting late, heavy meals and pre-bed screens. This is educational information; talk to your clinician before making changes or starting supplements.
Why is it harder for women over 30 — and through menopause — to lose weight?
Because three interconnected hormone systems shift, each shaped by your genes. Estrogen begins declining around 30 and changes where fat is stored; in menopause, fat moves from the hips and thighs to the belly and metabolism slows, so the same diet and routine that once worked stops working. Genes for the aromatase enzyme (CYP19A1), estrogen receptors (ESR1/ESR2), and estrogen clearance (COMT) determine how strongly these effects hit. Layered on top are cortisol (chronic stress) and thyroid (T4-to-T3 conversion, influenced by DIO2), plus rising insulin resistance. Dr. Pobee calls this the ‘Bermuda Triangle’ of cortisol, thyroid, and estrogen. Understanding your genetic tendencies ahead of time lets you prepare — supporting estrogen detox, balancing carbs and protein, strength training, and managing stress. Any testing or treatment should be individualized with your physician.
Can your genes really explain why diets haven’t worked for you?
Dr. Pobee’s central message is that genetics provide a personalized roadmap, not a one-size-fits-all plan. Single-nucleotide polymorphisms (SNPs) — tiny ‘typos’ in genes — influence how you handle cortisol, convert thyroid hormone, metabolize estrogen, respond to insulin, and even why you crave certain foods (a chocolate craving, for example, may signal magnesium deficiency, since modern soil is depleted). She groups patterns into ‘genetic avatars’ (such as cortisol carriers, sugar shapers, dopamine drivers, and fatigue fighters) to make the information actionable. Both physicians stress combining genetics with bloodwork and looking at the whole picture — polygenic patterns rather than a single SNP — because some variants are protective and some raise risk. Genetic testing should be interpreted with a qualified clinician, and results used to guide, not replace, individualized care.
Are GLP-1 weight-loss drugs (like Ozempic) a good solution?
Both doctors urge nuance. Dr. Pobee cautions that these drugs quiet ‘food noise’ but don’t fix underlying nutrient deficiencies, cortisol problems, or hormone imbalances — and that stopping them, after metabolism has slowed and muscle has been lost, often leads to rapid regain as fat, leaving people metabolically worse off. Dr. Druz notes a different cardiology use case: these medications (and SGLT2 inhibitors) can reduce inflammation and the fat around the heart and its vessels, and trials have shown cardiac benefits that don’t track one-to-one with weight loss. In her practice they’re typically used in modified, ‘microdosed’ regimens to limit side effects — and always built on a lifestyle foundation, without which results aren’t sustainable. Decisions about any medication should be made with your own physician based on your individual situation.

Key Terms Referenced in This Episode
Cortisol Carrier: Dr. Pobee’s term for someone whose genetics cause prolonged, hard-to-clear cortisol elevation under stress — driving belly fat, cravings, and weight-loss resistance.
SNP (Single-Nucleotide Polymorphism): A tiny ‘typo’ in a gene — a single-letter change — that can alter how a hormone or enzyme works.
NR3C1 (Glucocorticoid Receptor): The gene for the cortisol receptor; certain variants leave cortisol elevated longer under stress.
COMT: An enzyme/gene that clears estrogen (and dopamine); slow variants cause estrogen buildup, fast variants clear it too quickly.
Aromatase (CYP19A1): The enzyme that converts testosterone into estrogen; its activity level shifts fat storage and estrogen balance.
Estrogen Receptors (ESR1/ESR2): Genes controlling how the body responds to estrogen; variants are linked to higher fat storage and menopausal weight-loss resistance.
Estrogen Dominance / Predominance: A relative excess of estrogen (often from poor clearance) tied to bloating, fluid retention, and stubborn weight.
DIO2 & T4→T3 Conversion: T4 is the storage thyroid hormone; DIO2 variants impair its conversion to active T3, slowing metabolism.
Reverse T3: An inactive ‘anti-hormone’ the body can make instead of T3 — often when cortisol is high — blocking metabolism.
Insulin Resistance (IRS1): Reduced cellular response to insulin; worsens as estrogen falls and promotes fat storage and energy crashes.
Genetic Avatars: Pobee’s groupings (e.g., cortisol carriers, sugar shapers, dopamine drivers, fatigue fighters) that turn many SNPs into an actionable ‘story of you.’
Epicardial Fat: Fat wrapping the heart that can constrict and infiltrate the muscle — linked to atrial fibrillation and obesity-related heart failure.
Polygenic Risk Score: A combined read of many gene variants — some protective, some risky — giving a fuller picture than any single SNP.
