Insulin resistance has quietly become the connective tissue behind half of modern medicine's biggest problems: obesity, type 2 diabetes, fatty liver, heart disease, PCOS, and even Alzheimer's. It rarely shows up as a diagnosis on its own, which is exactly why so many doctors and scientists have spent hours on podcasts trying to explain it in plain language. We combed through our full library of episode summaries to find the conversations that actually teach you something, not just the ones that mention the term in passing.
Below are ten episodes worth your time, ranked by how much real, usable information each one packs in. You'll find metabolic scientists making the case that insulin (not calories) drives fat storage, GPs who reversed their patients' diabetes with a few carb swaps, and specialists connecting insulin resistance to fields you wouldn't expect, like psychiatry and cardiology. Pick the one that matches your angle in, or work through the list.
Female Hormone Health, PCOS, Endometriosis, Fertility & Breast Cancer | Dr. Thaïs Aliabadi
Andrew Huberman sits down with OB/GYN Dr. Thais Aliabadi for a deep dive into PCOS, and insulin resistance sits at the center of it. Aliabadi explains that 70 to 80 percent of PCOS patients don't ovulate, even with seemingly regular cycles, and that the syndrome is bound up with insulin dysfunction from the start of her stepwise treatment plan through GLP-1s. She also drops a striking personal reveal: a lifetime-risk calculation led her to a double mastectomy that uncovered cancer no one was looking for. Listen if you or someone you love has been brushed off with a vague PCOS diagnosis and wants a real framework for what's happening hormonally.

Max Lugavere joins Joe Rogan to unpack his documentary Little Empty Boxes, and the insulin angle here is the sleeper: researcher Suzanne de la Monte's framing of Alzheimer's as 'type 3 diabetes,' a form of insulin resistance in the brain. Lugavere lays out the retracted 2006 amyloid paper that misdirected sixteen years of research, then ties ultra-processed food directly to dementia risk, noting each 10 percent bump in ultra-processed intake tracks with a 25 percent higher Alzheimer's risk. This is the episode for anyone who thinks of insulin resistance as a weight problem and hasn't connected it to brain health yet.
Read the full episode notesInsulin Expert: How To 'Drain' Your Liver of Fat (Do This!)
Bikman makes his central argument in the most direct terms possible: remove insulin from the equation and it becomes 'completely impossible' to get fat no matter what you eat, a claim he backs by pointing to type 1 diabetics who skip insulin and stay lean even overeating. He also live-tests exogenous ketones on a visibly skeptical Steven Bartlett, and shares that a single shot of ketone supplement dropped his own blood pressure from 139/90 to roughly 110/70 in an hour. Anyone curious about the science behind low-carb and keto diets, minus the internet hand-waving, should start here.
Read the full episode notesFatty Liver Expert: The Toxic Ingredient Silently Filling Your Liver With Fat - Dr David Unwin
This is the most practical entry on the list. NHS GP David Unwin explains how he converted an entire practice to low-carb eating after one furious patient proved him wrong, and now says 93 percent of his pre-diabetic patients get back to normal blood sugar. His glycemic-load visuals land hard: 150 grams of boiled rice works out to about 10 teaspoons of sugar, and a bottle of barbecue sauce holds roughly 30. He's also disarmingly honest that his own financial incentives once kept patients on metformin longer than necessary. Ideal for anyone who wants a doctor's playbook, not just the theory.

A cardiologist with roughly a quarter-million patients behind him argues that heart disease is fundamentally driven by chronically high insulin and visceral fat, not just cholesterol. Jamnadas describes supervised fasts running from 72 to 183 days that reversed diabetes and dropped one patient from 400 to 210 pounds, and makes the contrarian case that over-doing aerobic cardio can leave people with more coronary disease than sprinters and lifters. He also claims nearly 70 percent of homes carry some mold toxicity that can worsen artery disease. Worth it for anyone focused on heart health who has never heard insulin discussed as the root cause.

Best known for his reversal on the COVID vaccine, cardiologist Aseem Malhotra also makes a sharp, less controversial case here: insulin resistance, not statin-worthy cholesterol, is the most important biological driver of arterial plaque. He cites data claiming statins extend life by only about 4.2 days over five years in industry-funded trials, and notes only one in eight US adults has all five metabolic-health markers in the normal range. The vaccine material will grab headlines, but the insulin resistance and lifestyle-medicine segment is the reason it's on this list. Good for skeptics of mainstream cardiology who want the metabolic argument laid out.
Read the full episode notesThe Insulin & Glucose Doctor: This Will Strip Your Fat Faster Than Anything!
Bikman's second appearance on this list goes broader than the first, arguing insulin resistance is the shared root of Alzheimer's, heart disease, PCOS, and even erectile dysfunction, and that roughly 88 percent of US adults carry some degree of it. He splits the causes into a 'fast lane' of stress and inflammation and a 'slow lane' of enlarging fat cells, and claims a Swedish longevity study found the longest-lived people had good glucose control alongside high cholesterol, complicating the standard cholesterol narrative. He also flags that 40 percent of weight lost on GLP-1 drugs is lean mass, including muscle and bone. Listen for the widest-lens view of why insulin resistance matters across the whole body.

Dr. Boz treats insulin resistance as measurable 'trash' building up in the body and brain, and gives listeners an actual tool for tracking it: her 'Dr. Boz ratio,' dividing blood glucose by blood ketones. The case studies are the hook, including a 41-year-old Down syndrome patient with Alzheimer's who spoke a three-syllable word for the first time after three weeks of keto, and her own mother's cancer markers dropping 70 percent in six weeks on diet alone. She's also candid that she personally couldn't reach ketosis for nine months despite being a physician. Best for people who want a concrete, numbers-based way to know if their protocol is working.
Read the full episode notesGlucose Goddess: The 10 Glucose Hacks!
The Glucose Goddess returns with the most immediately actionable episode on the list: ten small changes that flatten glucose spikes without cutting a single food out. Two stand out, eating your meal in order (veggies, then protein and fat, then starch) can cut a meal's glucose spike by up to 75 percent, and a tablespoon of vinegar before eating can cut it by up to 30 percent. She also argues PCOS often isn't a distinct condition so much as a cluster of insulin-resistance symptoms, present in 60 percent of cases. Great starting point for anyone who wants results this week, not a research briefing.
Read the full episode notesThe Keto Psychiatrist: What Keto Is Really Doing To Your Body! Can It Cure 43% Of Mental Illness?
A Harvard-trained psychiatrist makes the least expected connection on this list: insulin resistance and brain inflammation as drivers of depression, bipolar disorder, schizophrenia, and ADHD. Ede cites a study where 43 percent of patients with treatment-resistant bipolar disorder, depression, or schizophrenia reached clinical remission on a ketogenic diet, and shares her own story of a health crisis in her 40s that resolved on a low-carb, meat-heavy diet she says 'should theoretically kill me.' She also notes children with obesity and adults with type 2 diabetes are each about twice as likely to have ADHD. Essential listening for anyone treating mental illness as purely psychological and ignoring the metabolic piece.
