Episode 144 | Cortisol Rhythms and Insulin Resistance

Insulin resistance isn't necessarily an all-or-nothing condition. Skeletal muscle can become insulin resistant while other tissues continue responding differently—and the pancreas may compensate by producing enough insulin to keep fasting glucose and HbA1c looking completely normal. In this episode of The Health Pulse, we explore a fascinating piece of metabolic research suggesting that when stress hormones are released may matter independently of how much is released. We begin with the normal circadian rhythm of cortisol. Rather than remaining constant throughout the day, cortisol typically rises around the biological morning and declines toward night, with additional ultradian pulses layered onto that daily rhythm. This changing signal helps synchronize metabolism with the body's internal clock. But what happens when that rhythm becomes flattened? We examine a controlled Cell Reports mouse study that manipulated glucocorticoid timing while avoiding the usual confounding effect of simply increasing overall hormone exposure. The animals developed substantial adiposity despite eating a standard diet, but their metabolic dysfunction looked strikingly different from conventional diet-induced obesity. One of the most interesting findings was tissue-specific insulin resistance. Skeletal muscle developed pronounced insulin resistance while adipose tissue retained comparatively greater insulin responsiveness and capacity to store lipid. That altered pattern of fat handling was accompanied by relative protection from the severe fatty liver typically associated with diet-induced metabolic dysfunction. The study provides an important mechanistic lesson, but also an important limitation: these findings come from mice and should not be treated as proof that flattened cortisol rhythms produce the same metabolic phenotype in humans. We then translate the physiology into a broader clinical framework. When skeletal muscle becomes resistant to insulin, pancreatic beta cells can compensate by secreting increasingly large amounts of insulin. This hyperinsulinemia can maintain normal glucose for a considerable period, potentially allowing metabolic dysfunction to develop before conventional glucose markers become abnormal. We also explain why detecting abnormal cortisol timing isn't as simple as ordering one morning cortisol level. A single measurement provides a snapshot, while circadian dysfunction is fundamentally about the shape and timing of a rhythm. Instead of trying to diagnose this physiology from cortisol alone, we discuss metabolic measurements that can provide additional context, including fasting insulin alongside fasting glucose, HOMA-IR, and insulin measurements during an oral glucose tolerance test. Finally, we explore practical signals that help reinforce circadian organization: consistent sleep and wake times, bright light during the biological morning, reducing excessive light exposure at night, appropriate meal timing, and regular physical activity. Resistance training adds another advantage because muscle contraction can stimulate GLUT4 translocation and glucose uptake through pathways involving AMPK that are less dependent on insulin signaling. The takeaway isn't that disrupted cortisol rhythms explain every case of insulin resistance or weight gain. It's that metabolism depends not only on how much of a signal the body receives, but also where and when that signal occurs. Sometimes the first sign of insulin resistance isn't high blood sugar. The body may simply be working much harder to keep that blood sugar looking normal. 📞 Need lab work done from the comfort of home?

Episode 143 | IL-6 and the Hidden Risk of Heart Failure

Your hsCRP comes back in the “normal” range. Does that mean inflammation isn't contributing to your cardiovascular risk? For people with type 2 diabetes, the answer may be more complicated. In this episode of The Health Pulse, we explore emerging evidence connecting interleukin-6 (IL-6), insulin resistance, and heart failure—and why one of the most commonly measured inflammation markers, hsCRP, may not always capture the full story. We begin with the cardiorenal-metabolic connection. Type 2 diabetes doesn't affect glucose in isolation. Insulin resistance, vascular dysfunction, kidney disease, sodium retention, visceral adiposity, and chronic inflammation can interact to increase pressure and volume stress on the heart. Over time, these disturbances can contribute to cardiac remodeling and conditions such as heart failure with preserved ejection fraction (HFpEF). Then we compare two biomarkers that are often discussed as though they measure the same thing: IL-6 and high-sensitivity C-reactive protein (hsCRP). IL-6 is an upstream signaling cytokine produced by multiple tissues and immune cells, including dysfunctional adipose tissue in chronic metabolic disease. CRP sits farther downstream: inflammatory signaling, including IL-6, stimulates the liver to produce it. That distinction may matter when trying to understand the biological processes driving risk rather than simply detecting a generalized inflammatory response. We examine findings from an analysis connected with the long-running Look AHEAD trial, where IL-6 showed a stronger relationship with incident heart failure than hsCRP in adults with type 2 diabetes. The findings raise an important question: could upstream inflammatory signaling reveal cardiometabolic risk that a conventional downstream marker sometimes misses? There is also a more hopeful side to the story. Lifestyle intervention can influence inflammatory biology. Improvements in physical activity, body composition, metabolic health, and visceral adiposity can reduce chronic inflammatory signaling, including IL-6. But IL-6 comes with an important paradox. During exercise, contracting skeletal muscle can temporarily release large amounts of IL-6 as a myokine involved in fuel mobilization and adaptation. That short-lived physiological pulse is very different from persistently elevated IL-6 associated with dysfunctional adipose tissue and chronic immune activation. Context matters. We also explain why IL-6 isn't ready to become a simple standalone screening test. Levels can vary with infection, exercise, timing, inflammatory disease, and other factors, and routine clinical interpretation remains less standardized than established cardiovascular biomarkers. Instead, we zoom out to the broader cardiometabolic picture. Depending on the individual, markers such as HbA1c, fasting insulin, ApoB, eGFR, urine albumin-to-creatinine ratio, and BNP or NT-proBNP can help evaluate different components of metabolic, kidney, vascular, and cardiac risk. The lesson isn't to replace hsCRP with IL-6. It's to recognize that inflammation is a network, not a single number—and a reassuring laboratory result should always be interpreted within the larger metabolic picture. 📞 Need lab work done from the comfort of home?

Episode 142 | The Normal Blood Sugar Trap

What does it actually mean to reverse type 2 diabetes? If medications bring your HbA1c back into the normal range, has the disease improved—or has the glucose simply been controlled? In this episode of The Health Pulse, we examine a revealing clinical trial in people with newly diagnosed type 2 diabetes. An aggressive four-drug strategy normalized glucose in roughly 90% of participants during 16 weeks of treatment. But after the medications were withdrawn, that early advantage did not translate into higher rates of sustained, medication-free remission. That difference exposes one of the most important concepts in metabolic health: normalizing a biomarker while treatment is being taken is not the same as changing the underlying disease state. We begin with HbA1c, one of the most useful tools for diagnosing and monitoring diabetes, but a marker that cannot tell the entire metabolic story by itself. Glucose may improve while insulin resistance, hyperinsulinemia, ectopic fat, fatty liver, and cardiovascular risk remain. We then follow type 2 diabetes deeper into the liver and pancreas. As excess energy begins accumulating in tissues that aren't designed to store large amounts of fat, lipid intermediates can interfere with insulin signaling. The insulin-resistant liver continues releasing glucose while the pancreas compensates by producing more insulin. Over time, increasing metabolic pressure can impair beta-cell function, including the rapid first-phase insulin response needed to control glucose after meals. This helps explain why early intervention matters—and why diabetes risk can't be reduced to BMI alone. We explore the personal fat threshold, the idea that individuals differ in how much fat they can safely store before excess energy begins accumulating ectopically in organs such as the liver and pancreas. From there, we examine strategies capable of reducing that metabolic pressure. Substantial weight loss when appropriate, carbohydrate restriction, resistance training, and metabolic surgery can reach the problem through different mechanisms. We explain how muscle contraction can stimulate glucose uptake through pathways involving AMPK and GLUT4 with less dependence on insulin, and how metabolic surgery can rapidly alter appetite, nutrient signaling, and gut hormones such as GLP-1. Finally, we discuss what deeper metabolic monitoring can add beyond HbA1c, including fasting insulin, HOMA-IR, C-peptide, triglycerides, and ApoB. These markers can provide additional context about insulin demand, endogenous insulin production, lipid metabolism, and cardiovascular risk. Remission is an extraordinary goal, but it shouldn't be confused with a cure. Even after glucose returns to the non-diabetic range without glucose-lowering medication, long-term monitoring remains important because metabolic dysfunction and hyperglycemia can return. If you're tracking type 2 diabetes using HbA1c alone, this episode will help you ask a more important question: are we simply lowering the glucose—or reducing the metabolic pressure that made it rise in the first place? 📞 Need lab work done from the comfort of home?

Episode 141 | Beyond The Diet Wars

Is keto better because of carbohydrate restriction—or simply because people lose weight? Does a Mediterranean diet have unique metabolic advantages? And if calories and weight loss are identical, does the type of food you eat still matter? In this episode of The Health Pulse, we examine a tightly controlled randomized feeding study published in Cell Metabolism that offers an unusually clear way to investigate those questions. Instead of relying on food diaries, calorie estimates, or participants' ability to follow a diet at home, researchers provided the food and adjusted energy intake so participants following ketogenic, Mediterranean, and very-low-fat plant-forward diets all lost approximately the same 10% of body weight. That design helps separate two variables that nutrition research often struggles to untangle: the metabolic effects of weight loss itself and the effects of macronutrient composition. The results reveal an important organ-specific story. In skeletal muscle, insulin sensitivity improved substantially across the dietary approaches, suggesting that losing excess body fat itself may be a dominant driver of improved muscle glucose metabolism. The liver told a different story. Despite matched weight loss, the ketogenic diet produced substantially greater reductions in liver fat and improvements in hepatic insulin sensitivity. We explore the physiology that may help explain this difference, including changes in insulin and glucagon signaling, reduced carbohydrate availability, and suppression of de novo lipogenesis—the pathway through which the liver converts excess carbohydrate into fatty acids. That distinction matters because fatty liver and hepatic insulin resistance can appear early in the progression toward metabolic disease. We connect these findings with prediabetes, MASLD, fasting insulin, triglycerides, and continuous glucose monitoring, including why normal fasting glucose doesn't necessarily mean glucose regulation is normal throughout the day. We also tackle one of the most controversial parts of ketogenic nutrition: cholesterol. LDL cholesterol and ApoB are related, but they don't measure exactly the same thing. We explain why ApoB provides information about the number of circulating atherogenic particles, why lipid responses to carbohydrate restriction vary substantially between individuals, and why measurements obtained during active weight loss need to be interpreted in context. The larger lesson isn't that researchers have finally discovered one perfect diet. It's that different dietary strategies may produce different metabolic effects even when weight loss is identical—and those differences can matter depending on whether the primary problem is liver fat, insulin resistance, glucose control, cardiovascular risk, or something else. Finally, we discuss how laboratory testing can help personalize the decision, including fasting insulin, HbA1c, triglycerides, ApoB, liver enzymes, and CGM data, along with an important safety consideration for people taking glucose-lowering medications. In particular, combining substantial carbohydrate restriction with SGLT2 inhibitors can increase the risk of euglycemic diabetic ketoacidosis and requires appropriate medical guidance. If you're tired of hearing that either carbohydrates, fat, or calories explain everything, this episode offers a more useful framework: weight loss matters—but macronutrients can still influence what happens inside individual organs. 📞 Need lab work done from the comfort of home?

Episode 140 | Where Does Morning Glucose Come From on Keto?

Here are the episode description and companion blog embed intro. I’d keep the distinction between physiological glucose sparing and pathological insulin resistance central to this one. 🎙️ The Health Pulse – Episode Title: Why Is My Fasting Glucose High on Keto? The Dawn Phenomenon Explained Episode Description: Your CGM stays nearly flat all day. You're eating very few carbohydrates. You're producing ketones. Then you wake up and your fasting glucose is unexpectedly high. Where did that glucose come from? In this episode of The Health Pulse, we explore the physiology behind elevated morning glucose on a ketogenic or very-low-carbohydrate diet and explain why a higher fasting glucose doesn't automatically mean your diet has stopped working—or that you've developed diabetes. We begin with the dawn phenomenon. Sleep isn't metabolically inactive. As morning approaches, your circadian system coordinates changes in hormones including cortisol, growth hormone, glucagon, and catecholamines, signaling the liver to increase glucose availability in preparation for waking. That glucose doesn't have to come from last night's carbohydrates. Even during nutritional ketosis, the body maintains some circulating glucose. Through gluconeogenesis, the liver can produce it from substrates including glycerol, lactate, and glucogenic amino acids. We explain why this process is highly regulated and why the popular claim that “too much protein just turns into sugar” oversimplifies the physiology. Then we tackle the more complicated question: when is elevated fasting glucose a normal adaptation, and when should it raise concern? During prolonged carbohydrate restriction, skeletal muscle can reduce its reliance on glucose and preferentially use fatty acids, helping preserve glucose for tissues with greater glucose requirements—a phenomenon often described as adaptive glucose sparing. We examine this concept alongside controlled research showing that ketogenic diets can alter glucose tolerance, highlighting why a single glucose reading cannot tell you whether the underlying physiology is healthy or pathological. The metabolic context matters. We discuss how fasting insulin, HbA1c, triglycerides, ketones, HOMA-IR, and C-peptide, together with CGM patterns and clinical context, can help distinguish compensatory hyperinsulinemia and metabolic dysfunction from a low-insulin, carbohydrate-restricted state. We also explain why morning glucose needs a clean baseline. Poor sleep, sleep apnea, psychological stress, late-night meals, intense evening exercise, caffeine, illness, and normal day-to-day hormonal variation can all influence what appears on your meter the next morning. The takeaway is simple: don't diagnose your metabolism from one fasting glucose value. A morning glucose reading is one frame of a much larger metabolic movie. If you're following keto, low-carb, or using a CGM to understand your metabolism, this episode will help you interpret that mysterious morning rise with physiology instead of fear. 📞 Need lab work done from the comfort of home?

Episode 139 | Insulin Resistance Under The Hood

Your fasting glucose and HbA1c can look normal while your pancreas is working overtime to keep them that way. In this episode of The Health Pulse, we explore intermittent fasting as a strategy for insulin resistance, starting with a metabolic problem that conventional glucose testing can easily overlook: normoglycemic hyperinsulinemia. Insulin resistance often develops long before blood glucose reaches the prediabetes range. As tissues become less responsive to insulin, pancreatic beta cells compensate by secreting more of it. Glucose may remain normal, but the metabolic cost of maintaining that normal glucose continues to rise. So where does fasting fit? We break down what happens when the time between meals increases. As insulin concentrations fall and liver glycogen is gradually depleted, the body becomes increasingly able to mobilize stored fatty acids and produce ketones. Rather than viewing fasting as a magic switch, we explain it as a way of creating longer periods of low insulin signaling and allowing the body to transition between stored and incoming fuels. We also examine the popular connection between fasting and autophagy. While fasting influences nutrient-sensing pathways involved in cellular recycling, there is no universal human “autophagy clock” that suddenly switches on at a specific fasting hour. More fasting isn't automatically better, and aggressive multi-day fasting can introduce nutritional, hormonal, and muscle-preservation concerns. For many people, a more sustainable strategy may be a consistent 12- to 14-hour overnight fasting window, particularly when paired with appropriate meal timing. We explore research on early time-restricted eating, where improvements in insulin sensitivity have been observed even without significant weight loss, highlighting the importance of circadian biology and the potential metabolic consequences of eating late into the evening. But fasting cannot compensate for everything. Adequate protein, resistance training, maintaining skeletal muscle, post-meal movement, sleep, and food quality remain fundamental. Skeletal muscle is a major destination for glucose disposal, making muscle preservation especially important when using fasting or calorie restriction to improve metabolic health. We also discuss who needs to be particularly careful with fasting. People using insulin, sulfonylureas, SGLT2 inhibitors, or other glucose-lowering medications may require medical guidance because fasting can change medication requirements and, depending on the drug, increase the risk of complications such as hypoglycemia or ketoacidosis. Finally, we explain how to look beyond glucose when tracking metabolic improvement, including fasting insulin, HOMA-IR, triglycerides, ApoB, waist circumference, and changes in body composition. Intermittent fasting isn't magic—and it isn't necessary for everyone. But when used appropriately, meal timing can become one tool for reducing constant insulin demand and creating a metabolic environment that supports better insulin sensitivity. 📞 Need lab work done from the comfort of home?

Episode 138 | The Insulin Blind Spot

A normal fasting glucose or HbA1c doesn't necessarily mean your metabolism is healthy. For years, the pancreas may compensate for declining insulin sensitivity by producing increasingly larger amounts of insulin—keeping glucose looking reassuringly normal while metabolic dysfunction progresses beneath the surface. In this episode of The Health Pulse, we use Dr. Isabel Cooper's metabolic phenotype framework to explore the progression from normoglycemia with hyperinsulinemia to prediabetes and type 2 diabetes. Instead of looking only at glucose, we ask a more revealing question: how much insulin does your body need to produce to keep that glucose normal? We begin with the early compensatory phase, when insulin resistance develops but pancreatic beta cells can still increase insulin secretion enough to maintain normal blood glucose. This hyperinsulinemic, normoglycemic state can precede conventional diagnostic abnormalities and may provide an earlier opportunity to recognize metabolic dysfunction. From there, we follow the progression into impaired glucose regulation and established type 2 diabetes, eventually examining what happens when beta cells can no longer maintain the enormous insulin demand placed upon them. We also explore C-peptide as a marker of endogenous insulin production and why advanced beta-cell failure can create a very different metabolic picture from early hyperinsulinemic disease. The episode also examines selective hepatic insulin resistance, explaining how the liver can continue producing glucose while insulin-driven pathways contributing to fat production remain active. This helps connect insulin resistance with elevated triglycerides, ectopic liver fat, MASLD, glucotoxicity, lipotoxicity, and increasing cardiovascular risk. We then tackle an important distinction in diabetes management: improving HbA1c versus improving the underlying metabolic physiology. Clinical remission is valuable, but we explore why lower insulin demand, improved insulin sensitivity, reduced ectopic fat, and greater metabolic flexibility provide additional context when evaluating metabolic recovery. Finally, we focus on earlier detection and prevention. We discuss fasting insulin alongside fasting glucose, HOMA-IR, insulin measurements during an oral glucose tolerance test, ApoB, and C-peptide, as well as the influence of skeletal muscle, resistance training, sleep, cortisol, and the personal fat threshold on insulin sensitivity. If you've ever been told that your glucose is normal and assumed that means insulin resistance isn't developing, this episode explains why glucose may be only one part of the metabolic story. 📞 Need lab work done from the comfort of home?

Episode 137 | GKI and Cancer: Can Metabolic Therapy Really Starve a Tumor?

Stop eating sugar and you'll starve cancer” sounds convincing—but cancer metabolism is far more complicated. In this episode of The Health Pulse, we examine the science behind ketogenic metabolic therapy, the Glucose Ketone Index (GKI), and cancer, separating a legitimate area of research from claims that run far ahead of the evidence. We begin with the Warburg effect, the observation that many cancer cells consume large amounts of glucose and rely heavily on glycolysis even when oxygen is available. What appears inefficient from an energy perspective can provide rapidly dividing cells with metabolic intermediates needed to build proteins, lipids, nucleotides, and ultimately new tumor cells. This unusually high glucose uptake is so characteristic of many cancers that modern FDG-PET imaging exploits it to help identify metabolically active tissue. But that doesn't mean removing dietary sugar simply removes glucose from the body. The liver can manufacture glucose through gluconeogenesis, tightly defending blood glucose for tissues that require it. Instead, researchers studying ketogenic metabolic therapy are asking a more nuanced question: can lowering circulating glucose and insulin while increasing ketone bodies such as beta-hydroxybutyrate (BHB) create a metabolic environment that disadvantages certain tumors while continuing to fuel healthy tissue? That brings us to the Glucose Ketone Index. GKI combines blood glucose and ketone concentrations into a single ratio designed to describe the balance between these two circulating fuels. We explain how it's calculated, why researchers use it in metabolic oncology, and why chasing an extremely low GKI without clinical supervision can be dangerous. We also examine the current evidence, including recent research on ketogenic metabolic strategies in aggressive brain tumors. While findings remain scientifically interesting, GKI is not an established cancer-treatment target, and ketogenic therapy has not been proven to replace surgery, chemotherapy, radiation, immunotherapy, or other standard oncology treatments. Safety becomes especially important because cancer changes the metabolic equation. Cachexia, unintended weight loss, inadequate protein and calorie intake, medication interactions, and treatment-related nutritional problems can make aggressive fasting or carbohydrate restriction harmful for some patients. Glucose and ketone readings are also affected by stress hormones, sleep, medications, meal timing, and the dawn phenomenon, making isolated measurements easy to misinterpret. The takeaway isn't that metabolism doesn't matter—it clearly does. It's that metabolic therapy must be studied and applied with the same scientific rigor as any other cancer intervention. If you're interested in cancer metabolism, ketogenic therapy, GKI, or evidence-based oncology nutrition, this episode provides a framework for understanding what's promising, what's uncertain, and why careful medical supervision matters. 📞 Need lab work done from the comfort of home?
