  #304 - Did Low-Fat Diets Drive the Obesity Epidemic? | Dr. Arne Astrup & Mike Haney 30.07.2026 1u 17min

  For decades, we've been told that eating less fat is one of the healthiest things we can do. That advice reshaped the foods we buy, the way we think about weight loss, and even how parents feed their children.But what if we misunderstood fat in the first place?In this episode, nutrition researcher Dr. Arne Astrup traces how the war on fat began, why many of its core assumptions haven't held up under decades of research, and what we've learned instead. Rather than asking whether fat is "good" or "bad," he argues that the more useful questions are: What foods actually keep us healthy? Why do some people gain weight more easily than others? And what happens when we reduce nutrition to single nutrients instead of whole foods?Free course: Improve your metabolic healthGet our free email course on how glucose, nutrition, exercise, sleep, and measurement can help you build habits that support better energy and long-term health: ⁠⁠⁠⁠⁠⁠⁠https://levels.link/wnl⁠🎙️ About the Guest: Dr. Arne Astrup is a physician, nutrition researcher, and Professor Emeritus at the University of Copenhagen whose research focuses on obesity, appetite regulation, dietary fats, and cardiometabolic health.

  #303 - Why Healthcare Needs an Intelligence Layer | Dr. Robert Wachter & Mike Haney 15.07.2026 1u 17min

  Almost everything your doctor knows about you comes from a snapshot: a blood pressure reading, an annual lab, a handful of numbers meant to represent a constantly changing human body.That's beginning to change. New sensors promise far more continuous health data, and AI may finally give us the ability to interpret it. But medicine has been through a data revolution before, and almost none of what people initially promised actually happened.In the first episode of NextLevel, Mike Haney sits down with Dr. Robert Wachter, Chair of the Department of Medicine at UCSF and one of medicine's leading thinkers on technological change, to ask what healthcare's messy transition from paper to electronic records can teach us about the AI era.Wachter explains why digitizing medicine didn't transform care on its own, why your doctor is already overwhelmed by data, and why simply sending them continuous feeds from your watch, ring, or future sensors would make the problem worse.The missing piece is an intelligence layer: a system capable of deciding what matters, helping patients act when they can, and pulling clinicians in when they're actually needed.They also explore how AI is changing the balance of knowledge between doctors and patients, the danger of trusting systems that are usually right, what healthcare can learn from airplane cockpits, and why collecting more health data may be much easier than figuring out what any of it means.Free course: Improve your metabolic healthGet our free email course on how glucose, nutrition, exercise, sleep, and measurement can help you build habits that support better energy and long-term health: ⁠⁠⁠⁠⁠⁠https://levels.link/wnl⁠🎙️ About the Guest: Dr. Robert M.

  #301 - What Actually Moves the Needle on Cardiovascular Risk | Dr. Kevin Maki & Mike Haney 18.06.2026 1u 18min

  High cholesterol. Elevated ApoB. A positive CAC score. Now what?Most people quickly find themselves trapped between two extremes: simplistic advice to “cut saturated fat” and online influencers insisting cholesterol doesn’t matter at all.In this episode of A Whole New Level, Mike Haney sits down with clinical research scientist Dr. Kevin Maki to cut through the confusion.Drawing on more than 35 years of cardiovascular research, Maki explains why heart disease risk is about much more than LDL cholesterol alone. He breaks down the roles of inflammation, blood sugar, family history, kidney function, and lipoproteins, while also making a clear case for something many people resist: LDL and ApoB still matter. A lot.The evidence increasingly suggests that when it comes to atherosclerosis, lower for longer is better. That has important implications for diet, statins, and how early we should intervene.Mike and Dr. Maki also tackle saturated fat, seed oils, red meat, industry-funded research, and how to separate evidence from online nutrition debates.Free course: Improve your metabolic healthGet our free email course on how glucose, nutrition, exercise, sleep, and measurement can help you build habits that support better energy and long-term health: ⁠⁠⁠⁠https://levels.link/wnl⁠🎙️ About the Guest: Dr. Kevin Maki is founder and Chief Science Officer of Midwest Biomedical Research and an Adjunct Professor in the School of Public Health at Indiana University.

  #300 - Who Should Take GLP-1s? The Science of Obesity, Appetite & Weight Loss | Dr. Robert Kushner & Mike Haney 04.06.2026 1u 14min

  What are GLP-1 drugs actually doing in the body, who are they for, and why might some people want to think twice before treating them like a six-month shortcut?For years, obesity treatment focused largely on behavior: eat less, move more, stay motivated. Yet many people lost weight only to regain it. According to obesity medicine pioneer Dr. Robert Kushner, that wasn’t a failure of willpower. It was a failure to fully understand the biology driving weight regulation.In this episode of A Whole New Level, Mike Haney sits down with Kushner, one of the leading figures in obesity medicine and a lead investigator on the landmark STEP trials, to discuss how GLP-1 medications are changing the field. He explains why these drugs may be the first treatments capable of helping patients “fight biology with biology,” why appetite regulation appears to work differently in different people, and why many patients describe a dramatic reduction in food noise after starting treatment.But this conversation goes beyond how the drugs work. Kushner also addresses one of the biggest questions facing obesity medicine today: who should actually take these medications? He explains why obesity specialists evaluate far more than a number on the scale, why someone hoping to lose a modest amount of weight may want to think carefully before pursuing treatment, and why successful long-term health still requires changes that no medication can provide.They also discuss obesity as a disease, the promise and limitations of telehealth prescribing, and why maintaining weight loss often requires something deeper than motivation: a shift in identity.Free course: Improve your metabolic healthGet our free email course on how glucose, nutrition, exercise, sleep, and measurement can help you build habits that support better energy and long-term health: ⁠⁠⁠https://levels.link/wnl⁠🎙️ About the Guest: Dr. Robert Kushner is Professor Emeritus of Medicine and Medical Education at Northwestern University Feinberg School of Medicine and one of the pioneers of modern obesity medicine.

  #299 - Do Athletes Really Need More Carbs? | Dr. Andrew Koutnik & Mike Haney 21.05.2026 1u 31min

  Most athletes are told the same basic rule: the harder you train, the more carbs you need. But Dr. Andrew Koutnik argues the science is more complicated.In this episode, Mike Haney talks with Dr. Koutnik about how the body fuels exercise, why muscle glycogen may not explain “hitting the wall” as neatly as many people think, and why blood glucose, brain energy, insulin, and metabolic flexibility may matter more than conventional sports nutrition advice suggests.They discuss whether athletes really need 60, 90, or even 120 grams of carbs per hour, why some athletes may perform well on far less, and how to think about fueling as an individual experiment rather than a universal rule.

  #298 - Why AI Won’t Replace Doctors—But Will Change Everything Else | Dr. Ami Bhatt + Mike Haney 07.05.2026 1u 9min

  We can measure more about our health than ever before. Wearables track everything from heart rhythms to glucose trends, and AI can now identify patterns clinicians might miss. But more data does not automatically mean better health outcomes.In this episode, cardiologist and digital health expert Dr. Ami Bhatt joins Mike Haney to explore why medicine still struggles with prevention, how continuous health data can help patients take more agency, and where AI may actually improve care—not by replacing doctors, but by helping clinicians navigate the right information at the right time.They discuss the promise and pitfalls of wearables, the challenge of turning constant streams of health information into useful action, and why the future of medicine may depend on what Dr. Bhatt calls “collaborative intelligence”: humans and AI working together to make better decisions earlier.Free course: Improve your metabolic healthGet our free email course on how glucose, nutrition, exercise, sleep, and measurement can help you build habits that support better energy and long-term health: ⁠⁠⁠⁠⁠https://levels.link/wnl⁠About the guest: Dr. Ami Bhatt is the chief innovation officer (CIO) at the American College of Cardiology and the Chair of the FDA Digital Health Advisory Committee.

  #297 - Does Most Chronic Disease Come Down to “Energy Flow?” | Greg Mushen and Josh Clemente 23.04.2026 1u 35min

  Metabolic health is often simplified to a matter of blood sugar, but at its root, it is a complex system of energy substrate signaling. While many view chronic disease as an inevitable part of aging, a systems-thinking approach reveals that maintaining high "flux"—the capacity to efficiently move and clear energy through the body—is the primary lever for longevity. Without the stimulus of regular movement, even the most optimized diet can fail to prevent the accumulation of metabolic waste that leads to insulin resistance and heart disease.In this episode, we sit down with Greg Mushen, a technologist who turned his engineering mind toward his own biology after conventional medicine failed to address his chronic health issues. Mushen breaks down his "Theory of Flux" and why he believes the key to disease resistance lies in meeting our body's "clearance burden". From studying the activity levels of hunter-gatherer populations to debunking myths about walking and V2 max, Mushen provides a data-driven framework for optimizing health through the lens of evolutionary biology and systems engineering.Sign Up to Get Your Free Ultimate Guide to Glucose: ⁠⁠⁠⁠⁠⁠https://levels.link/wnl⁠⁠⁠⁠⁠In this episode, we cover:The Theory of Flux: Understanding health as the dynamic capacity to move nutrients and fuel through the system rather than a static set of markers.Insulin Resistance Reimagined: Why blood sugar is a symptom, not the root cause, and how fat accumulation in the liver and muscle disrupts signaling.The Power of PAL: Why a Physical Activity Level (PAL) of 2.0 is the "golden ratio" observed in disease-free subsistence populations.Walking vs. HIT: De-bunking the idea that you need high intensity to improve V2 max and why the "area under the curve" for oxygen consumption is what matters.The Saturated Fat Paradox: Comparing the Messiah and Chimané populations to understand how high activity levels can mitigate the risks of high-fat diets.Fiber as a Sensor: Why fiber is more than just "throughput" and acts as a critical environmental sensor for metabolic signaling.The "Walking Grifter" Philosophy: Why walking is the most under-leveraged tool for increasing metabolic flux with the lowest recovery cost.🎙 What Greg Mushen & Josh Clemente discuss:[00:53] — Greg’s transition from tech engineering to "debugging" his own biology.[06:55] — The mold exposure and chronic fatigue that sparked a deep dive into primary literature.[11:36] — How correcting a copper deficiency became a "point of light" for understanding micronutrients.[20:53] — Lessons from the Messiah: High saturated fat intake paired with extreme physical activity.[25:26] — Defining Flux: The capacity to clear substrate and prevent metabolic accumulation.[30:26] — The PAL 2.0 threshold: Why doubling your basal metabolic rate is the key to warding off chronic disease.[51:10] — Lipid Kinetics: Using the "sink and drain" analogy to understand LDL residence time.[01:00:19] — The Integral of Oxygen: Why walking 15,000 steps can be as effective for V2 max as short bursts of HIT.[01:17:16] — Why Greg changed his mind on plant-based vs. animal protein.[01:28:24] — Greg's personal stack: From 15k steps and resistance training to PD5 inhibitors and custom fiber blends.Levels helps you see how food affects your health, empowering you with the tools needed to achieve health goals and improve healthspan.

  #296 - The Truth About Protein: Why Exercise is the Secret to Muscle Growth and Longevity | Dr. Stuart Phillips & Mike Haney 09.04.2026 1u 10min

  Protein is often hailed as the ultimate nutrient for health and longevity, but the science suggests it is only half of the equation. While social media influencers debate the minutiae of protein grams, researchers have found that the vast majority of protein's benefits are "baked in" only when combined with physical activity. Without the stimulus of exercise, even the most optimized protein intake fails to move the needle on muscle growth or chronic disease prevention.In this episode of A Whole New Level, Mike Haney sits down with Dr. Stuart Phillips, a researcher who has spent over 25 years at McMaster University studying the intersection of protein, exercise, and human health. Dr. Phillips breaks down why the current RDA for protein is likely too low for optimal health and why the methodology used to set those standards is decades out of date.Dr. Phillips explains the "brick wall" analogy of muscle turnover—where synthesis and breakdown are in a constant tug-of-war—and how lifting weights acts as the primary driver for "the bricklayers". From the impact of anabolic resistance in aging to the truth about protein timing and kidney health, he provides a grounded, data-driven perspective on how to maintain a functional reserve of muscle as we age.Sign Up to Get Your Free Ultimate Guide to Glucose: ⁠⁠⁠⁠⁠https://levels.link/wnl⁠⁠⁠⁠In this episode, we coverThe RDA Debate: Why the standard 0.8 g/kg recommendation is a "preventing deficiency" baseline rather than an "optimized health" target.The Power of Exercise: Why 80% to 90% of protein's benefits are dependent on physical activity.Muscle as a Storage Depot: Understanding muscle as a functional reserve that dictates disease resistance and survival.Anabolic Resistance: How inactivity and aging make our cells less efficient at using amino acids.The Myth of Timing: Why the "anabolic window" is more like a "garage door" that stays open much longer than once thought.Protein Quality & Source: Comparing animal vs. plant proteins and why the "food matrix" matters more than isolated powders.Kidney Health: De-bunking the 60-year-old hypothesis that high protein intake causes kidney damage in healthy individuals.🎙 What Dr. Stuart Phillips & Mike Haney discuss:[00:00] — Why exercise is the "big driver" of protein's health benefits.[09:00] — Transitioning from the RDA (0.8 g/kg) to an optimized range of 1.2 to 1.6 g/kg.[30:31] — The limitations of "nitrogen balance" as a methodology for protein needs.[44:45] — Muscle as a structural substrate vs. carbs and fats as fuel.[01:10:05] — Anabolic resistance: Why we lose building efficiency as we age.[01:18:15] — The "Compound Interest" of muscle: Why starting early prevents a late-life mobility spiral.[01:28:10] — Hormones and muscle: The differing impacts of testosterone and estrogen during aging.[01:39:15] — Addressing the concerns regarding high protein intake and kidney function.[01:52:10] — Whole foods vs. supplements: Why the "bricklayers" care about amino acids, but the body cares about nutrients.[01:60:12] — Debunking the immediate post-workout protein shake myth.Levels helps you see how food affects your health, empowering you with the tools needed to achieve health goals and improve healthspan.

  #295 - The Science of Preconception: Measuring Fertility, Toxins, and Generational Health | Dr. Ann Shippy & Josh Clemente 27.03.2026 1u 7min

  Preconception health is one of the most powerful—yet overlooked—windows for influencing a child’s lifelong wellness. While fertility is often discussed in the context of age or medical intervention, emerging research suggests that the months leading up to conception are a critical "time capsule" for epigenetic health.In this episode of A Whole New Level, Levels Founder and CEO Josh Clemente sits down with Dr. Anne Shippy, a board-certified internal medicine physician and author of The Preconception Revolution. Dr. Shippy brings a unique, systems-based approach to fertility, moving beyond basic labs to uncover the root causes of infertility and chronic disease.Dr. Shippy explains why the "check engine light" of infertility is often a signal of deeper metabolic or environmental imbalances—and why age isn't always the primary driver of reproductive success. Drawing on her engineering background and years of clinical practice, she walks through how toxins, mitochondrial function, and the microbiome interact to shape the health of both parents and their future children.Along the way, the conversation explores the practical "mini-experiments" couples can run to optimize their biology—from tightening blood sugar control with CGMs to auditing the "chemical soup" of modern life.

  #294 - Cholesterol Science Explained: Why Your LDL Score Doesn’t Tell the Whole Story | Dr. Ronald Krauss + Mike Haney 12.03.2026 59min

  High cholesterol is one of the most widely discussed—and established—risk factors in medicine. But reams of research now show that while it is key to cardiovascular risk, it is not the whole story.In this episode of A Whole New Level, editorial director Mike Haney sits down with Dr. Ronald Krauss, one of the world’s leading lipid researchers and a pioneer in understanding how different forms of LDL—and the physiological factors around them—affect cardiovascular risk.Dr. Krauss explains why the basic link between cholesterol and heart disease is well established among experts—but also why the standard cholesterol panel often misses the deeper metabolic story. Drawing on decades of research, he walks through how lipoproteins, particle size, triglycerides, and metabolic health interact to determine whether cholesterol actually becomes dangerous.Along the way, the conversation explores why cardiovascular disease remains the leading killer despite statins and decades of research—and how factors like obesity, insulin resistance, and inflammation reshape the lipid landscape in ways that traditional tests may not capture.The result is a clearer framework for understanding cardiovascular risk: not just how much cholesterol is in the blood, but how it’s being transported, how long those particles circulate, and what metabolic conditions are driving them.Sign Up to Get Your Free Ultimate Guide to Glucose: ⁠⁠⁠https://levels.link/wnl⁠⁠In this episode, we coverWhy the cholesterol–heart disease link isn’t actually controversial among researchersCholesterol vs. lipoproteins: why the particles carrying cholesterol matter more than the number itselfSmall dense LDL: how triglyceride metabolism produces the most harmful particlesApoB and particle counts: why many researchers prefer measuring particles instead of cholesterol massLipoprotein(a): the genetically driven risk factor affecting up to a third of the populationMetabolic syndrome: the cluster of conditions that amplifies cardiovascular riskWhy carbohydrates and metabolic dysfunction can drive harmful lipid patternsThe saturated fat debate: why food context and metabolic health matter more than simple fat categories🎙 What Dr. Ronald Krauss & Mike Haney discuss:[01:09] — Why the cholesterol–heart disease link is largely settled science[02:27] — Why cardiovascular disease remains the world’s leading killer[04:42] — Inflammation and metabolic dysfunction in vascular disease[06:12] — The discovery of small dense LDL and why particle size matters[07:14] — Lipoprotein(a) as a major inherited cardiovascular risk factor[09:18] — “Residence time”: why particles that circulate longer cause more damage[11:24] — ApoB vs LDL-C: measuring particles instead of cholesterol mass[13:31] — The HDL paradox: why raising HDL hasn’t improved outcomes[15:28] — Metabolic syndrome and the five markers that amplify risk[17:16] — Why the saturated fat debate misses the bigger metabolic pictureLevels helps you see how food affects your health, empowering you with the tools needed to achieve health goals and improve healthspan.

  #293 - Why You Can’t Exercise Your Way to Weight Loss: The Constrained Energy Model | Dr. Herman Pontzer + Mike Haney 26.02.2026 55min

  You can’t outrun a bad diet—but it turns out you might not even be able to outrun a good one. In this episode of A Whole New Level, evolutionary anthropologist Dr. Herman Pontzer joins Mike Haney to dismantle the "armchair view" of metabolism and explain why more exercise doesn't necessarily mean more calories burned.Drawing on his groundbreaking research with the Hadza hunter-gatherer community and global meta-analyses, Dr. Pontzer explains the Constrained Energy Model: the phenomenon where our bodies hit a metabolic ceiling and begin "trading off" energy from vital systems like immunity and reproduction to account for physical activity. This conversation reframes weight loss not as a simple math problem of "calories in vs. calories out," but as a dynamic, evolutionary balancing act.Sign Up to Get Your Free Ultimate Guide to Glucose: ⁠⁠https://levels.link/wnl⁠In this episode, we cover:The Myth of Additive Energy: Why adding a 300-calorie run to your day doesn’t actually result in 300 extra calories burned over the long term.The Hadza Paradox: How hunter-gatherers who walk miles every day burn the same amount of total energy as sedentary Westerners.Metabolic Trading: How your body "pays" for exercise by dialing down inflammation, stress responses, and reproductive hormones.The Business of the Body: Why the human body acts less like a simple machine and more like a corporation reallocating a limited budget.The "Set Point" Debate: Whether our bodies are tracking pounds on a scale or the flow of energy in the gut.Practical Weight Management: Why diet is the primary tool for weight, while exercise is the primary tool for everything else.🎙 What Dr. Herman Pontzer & Mike Haney discuss:[0:01-0:52] The Additive Model vs. The Constrained Energy Model[1:24-2:48] Dr. Pontzer's Book Burn[3:33-4:21] Defining Energy Balance[5:15-6:50] Where the "Armchair View of Metabolism" Breaks Down[7:07-8:50] Comparing the Additive Model to the Constrained Energy Model[16:14-18:12] Energy Accounting: Where Daily Calories Go[18:13-20:57] The Body as a Business Metaphor[22:13-23:47] Specific Ways the Body Compensates for Increased Exercise[24:19-25:27] Modifying the Constrained Energy Limit (Diet and Weightlifting)[47:54-51:23] Diet is Key for Weight ManagementLevels helps you see how food affects your health, empowering you with the tools needed to achieve health goals and improve healthspan.

  #292 - Cardiac Imaging Explained: Why You Need a Calcium Score to Know Your Real Heart Risk | Dr. Matthew Budoff & Mike Haney 15.02.2026 53min

  Heart disease risk isn’t just about cholesterol. In this episode of A Whole New Level, Dr. Matthew Budoff explains why coronary artery calcium (CAC) scoring may be the most important test most people aren’t getting—and why imaging your arteries directly can reveal risk that blood tests alone can miss.Drawing on decades of research and data from the landmark MESA study, Dr. Budoff explains how calcium scoring predicts real cardiovascular events, how plaque actually forms and progresses, and why some people with high cholesterol never develop plaque—while others with “normal” labs do.This episode focuses on how to measure your actual cardiovascular risk, not just estimate it.Sign Up to Get Your Free Ultimate Guide to Glucose: ⁠https://levels.link/wnlIn this episode, we cover:Why CAC scoring is one of the strongest predictors of future heart eventsWhy cholesterol is critical—but only explains about half of heart disease riskWhy some people with very high LDL have zero plaque—and others with normal labs have dangerous plaqueWhy CAC is best understood as the “tip of the iceberg” of total plaque burdenWhen to escalate to CT angiography and advanced imagingHow plaque regression is possible—and what interventions actually drive itThe future of cardiac risk prediction: Lp(a), inflammation, and AI-driven plaque analysisThis conversation reframes heart risk around what’s actually happening inside your arteries—not just what shows up in bloodwork.🎙 What Dr. Matthew Budoff & Mike Haney discuss:[01:35] — Coronary calcium is the strongest predictor of heart events[02:38] — What a high calcium score actually means for risk[04:00] — Why rising calcium is not “healing.”[11:07] — The role of fat tissue and inflammation in plaque formation[16:37] — Why do many people with high cholesterol have no plaque[17:55] — Why imaging is the only way to truly know your risk[37:07] — Calcium as the “tip of the iceberg” of total plaque burden[~52:00] — Why CAC is the practical first step before advanced imaging[~1:02:00] — When CT angiography adds critical information[~1:14:00] — How plaque regression actually happens in the real world[~1:22:00] — The next frontier: Lp(a) and inflammation as treatment targetsLevels helps you see how food affects your health, empowering you with the tools needed to achieve health goals and improve healthspan.
