    What’s Wrong With Me?” What AI Gets Right — And What It Gets Really Wrong

    In this episode, I explore where AI can genuinely help with health questions, where it can fall dangerously short, and how to use it more wisely before trusting it with decisions that really matter. AI tools like ChatGPT, Claude, Grok, and Gemini can be useful for understanding lab results, summarizing a doctor’s visit, preparing questions before an appointment, or making sense of complicated medical language. But when people ask AI, “What’s wrong with me?” or “Should I go to the hospital?” the answer can depend heavily on whether the user provides enough clinical context. I tested this myself with two invented scenarios: hand pain and a concerning headache. In both cases, the AI gave general guidance but failed to ask key questions a physician would naturally ask, such as my age, whether symptoms came on suddenly, whether I had experienced this before, or whether there was relevant family history. When I explicitly asked the AI to interview me first, the answers improved dramatically. Research supports that concern. A recent Nature Medicine study found that when real users interacted with AI about clinical scenarios, the AI gave the correct triage recommendation in only about 43% of cases and often underestimated urgency. The problem was not always that AI lacked medical knowledge. It was that users often did not provide enough information, and the AI did not reliably ask for what it needed. Another Nature Medicine study tested ChatGPT Health using complete clinical vignettes. Even with all the information provided, the AI struggled with the most urgent and least urgent cases. It sometimes recognized serious diagnoses but recommended delayed care when immediate emergency care was appropriate. That suggests the issue is not just knowledge, but judgment. AI does perform better in lower-risk, supportive roles. It can translate medical jargon into plain language, explain abnormal lab results, organize a visit summary, and help patients prepare better questions for their doctor. Recording a medical visit with the doctor’s permission and then using AI to create a personal summary can be especially helpful, though AI-generated clinical notes still need careful physician review. The most practical strategy is simple: before asking AI for health guidance, tell it, “Before you respond, please ask me all the questions you need to give me accurate information about my situation.” This does not make AI a doctor, but it can make the interaction more useful and less incomplete. Takeaways: AI can be helpful for understanding, organizing, and preparing for healthcare conversations, especially when the stakes are relatively low. AI is not yet reliable enough to determine whether symptoms are urgent or whether you should go to the ER. When using AI for health questions, ask it to interview you first, and when symptoms feel serious, unusual, sudden, or frightening, do not rely on AI as your final decision-maker. Send us Fan Mail

    #69 Being Happy: Physiology Often Beats Insight

    In this episode, I explore a difficult but important idea: when it comes to depression, anxiety, fear, and emotional suffering, changing physiology often works better than understanding the story behind the pain.  I begin with a simple question: why do we assume insight should heal us? As human beings, we naturally look for patterns and explanations, but explanation is not the same as relief. I share two personal examples—my years of dysthymia that lifted quickly with Wellbutrin, and my exercise-related fears that insight alone never resolved—to show how biology can sometimes succeed where understanding falls short. From there, I look at everyday examples that make this idea easier to grasp. A bad night of sleep can worsen emotional balance, while a good night of sleep can make the world feel more manageable again. Likewise, structured breathwork can calm the body and improve mood, suggesting that sometimes the body changes first and the mind follows. Sleep-loss review and breathwork trial are two examples I discuss.  I then turn to more dramatic examples in mental health treatment. ECT can improve severe depression without requiring a better narrative about the past, and vagus nerve stimulation offers another reminder that mood is also a biological state. I also touch on emerging research around psilocybin and neuroplasticity , while emphasizing that this area remains early and experimental.  Finally, I explore therapies that work not by increasing insight, but by retraining the nervous system. Exposure-based approaches can reduce fear through repeated safe contact with what scares us, and I discuss why I’m personally experimenting with EMDR as a way to loosen the connection between exertion and fear. My goal is not to dismiss therapy, but to make a clearer distinction: insight can be meaningful, but it does not always reduce suffering. Sometimes the nervous system needs calming, retraining, or direct biological support.  Takeaways If understanding your sadness, anxiety, or fear has not brought relief, it may be worth exploring approaches that target sleep, breathing, body state, or brain physiology directly. Don’t confuse explanation with treatment. And remember: sometimes the path to feeling better begins not with a better story, but with a different state.  Send us Fan Mail

    When Acupuncture and Massage Work—and When They Don’t

    This episode explores what massage and acupuncture can genuinely help with, where the benefits appear to be mostly short term, and where the evidence simply does not support the bigger claims. Massage and acupuncture are widely used, and many people spend real time, money, and hope on them. I walk through an important distinction: feeling better is not the same as changing the underlying problem or speeding healing. A treatment may reduce pain, soreness, anxiety, or tension without actually fixing injured tissue or altering the course of recovery. I also explain why the research can be so tricky to interpret. When massage or acupuncture is compared with no treatment, the results often look encouraging. But when they are compared with a sham treatment, the benefits usually shrink. That matters because even light touch, attention, expectation, and the ritual of care may create real symptom relief on their own. I discuss this challenge using a recent JAMA Network Open review. For massage, the strongest case is short-term symptom relief. I review studies showing benefit after surgery, including improved pain, anxiety, and relaxation in cardiac surgery patients and better perceived comfort after colorectal surgery But when massage is studied for neck pain, low back pain, or post-exercise recovery, the picture is much more mixed. It may help soreness or pain in the short term, but it does not clearly improve function, healing, or athletic performance, as seen in reviews on neck pain, low back pain and sports recovery For acupuncture, I look at the areas where evidence is more promising and where it is less convincing. A recent review found possible benefit for delayed vomiting during cancer care and a Cochrane review found that acupuncture may help with migraine prevention For chronic low back pain, acupuncture may help compared with no treatment, but it is not clearly better than sham acupuncture, according to a Cochrane review.  For tennis elbow, the evidence suggests possible short-term pain relief, but not strong proof of lasting benefit or faster recovery, based on this systematic review Takeaways: Massage seems most helpful for relaxation, short-term relief, and reducing soreness, but not for clearly accelerating healing. Acupuncture appears to have narrower evidence-based uses, especially migraine prevention and possibly delayed vomiting in cancer care. When claims expand into fixing injuries, correcting structure, boosting immunity, or treating a wide range of unrelated conditions, the evidence becomes much weaker. Send us Fan Mail

    #67: Why Smart People Fall For Health Headlines

    “All natural.” “Doctor recommended.” “Used for 5,000 years.” If you’ve ever felt your hand reach for a product before your brain finishes thinking, you’re not alone and you’re not broken. We dig into why health hype works even on people who know better, and how to build a simple mental pause that protects your everyday health decisions. We start with a personal story from the vet’s office that exposes a universal trap: confusing sequence with proof. From there, we separate two forces that drive modern health misinformation. First are logical fallacies, the broken arguments baked into headlines and wellness marketing, like appeal to nature and appeal to authority. Second are cognitive biases, the shortcuts in our own minds, like the halo effect, social proof, pattern seeking, and narrative bias. Once you can name both, you can stop the “feels true” reaction from taking over. Then we pressure-test three familiar hype machines: AG1-style supplement marketing, ancient-tradition claims around remedies like turmeric, and detox cleanses built on fear of “toxins” and the comfort of a single root cause. You’ll leave with a clear toolkit, including the exact questions to ask about evidence, expertise, mechanisms, and randomized controlled trials, so you can evaluate health claims without cynicism and without getting played.

    #67 Stress Reduction: What Actually Works—and What’s Just Wellness Hype

    Stress is everywhere and so is the marketing. Nearly half of US adults say they feel stressed often, and the wellness world is ready with a supplement, a lab panel, or a pricey device for every symptom. We wanted a cleaner answer: what is stress, what can we measure at home, and what actually reduces stress in a way that’s grounded in real studies rather than hype. We start by defining stress in a practical way: stress rises when the demands you perceive exceed the resources you think you have. That helps explain why stress can feel so intense even when there’s no single “stress blood test” to prove it. From there, we walk through simple, objective tracking tools you can use right away, led by the Perceived Stress Scale (PSS-10). We also talk about supportive signals like resting heart rate and heart rate variability (HRV), and why cortisol testing often creates more confusion than clarity in day-to-day life. Then we get into what works. The strongest evidence supports unsexy basics like better sleep and regular exercise, plus approachable mind-body tools like breathwork and mindfulness meditation. We also cover two surprising areas with research behind them: music therapy and aromatherapy (often lavender). Finally, we call out common red flags and popular myths, including “adrenal fatigue,” questionable supplement stacks, and consumer vagus nerve stimulation gadgets that borrow credibility from real implantable medical devices without delivering real proof. If you want a plan you can trust, we outline an N of 1 stress reduction experiment: measure your baseline, test one change for a week or two, re-measure, and keep only what moves your numbers and your life.

    #66: A big coffee study won't change what I do....

    Visit my website Bold claims make great headlines; clear evidence makes better habits. We take a hard look at the widely shared study suggesting two to three cups of coffee cut dementia risk by 20 percent and unpack what those numbers really mean for your brain and your daily routine. First, we break down the Harvard JAMA research: massive cohorts of nurses and physicians, decades of follow-up, and self-reported diet data that carry real strengths and built-in limits. We explore why observational studies can’t prove causation, how confounders like sleep, exercise, and income can bend results, and why tea showing similar benefits while decaf shows none points to caffeine yet refuses a tidy explanation. Then we translate relative risk into absolute terms to show how a big percentage drop can still be a small difference in real life, and we discuss the publication bias that comes from testing many hypotheses and promoting only the eye-catching hits. Next, we turn to trials where the science gets sharper. The CRAVE study randomized coffee days in healthy adults with continuous heart monitoring and found no rise in atrial abnormalities that lead to atrial fibrillation, though there was a bump in benign PVCs. For those with a history of AF, the DCAF trial offers a surprise: participants who kept drinking coffee had almost half the recurrence rate compared with those who quit, suggesting caffeine didn’t worsen outcomes and might even help. The message for most people is reassuring—coffee isn’t the arrhythmia trigger it’s often made out to be. Our bottom line is practical and personal. If coffee fits your life and doesn’t wreck your sleep, enjoy one or two cups without expecting miracles. Protect your rest first, because sleep debt is a far clearer risk to cognition than a second espresso is a remedy. Stay curious, ask how a study was designed, and look for consistent results across methods before changing routines.

    #65: Can I Eat All the Salt That I Want?

    You read everywhere that you “should” cut salt—especially if your blood pressure is up. But salt also makes food enjoyable. In this episode, I walk through the human evidence (not animal studies) and frame salt as a risk–benefit tradeoff: when does sodium meaningfully matter, for whom, and how can you test your sensitivity? Big questions we answer If you have high blood pressure: does lowering salt always help?If your BP is normal but you have heart/kidney risk: does salt matter?If you’re basically healthy: how worried should you be?Key takeaways Sodium is essential (nerves, muscles, fluid balance)—the issue is dose and individual response.Most sodium comes from packaged/restaurant foods (not your salt shaker).Salt restriction lowers BP, but the average effect is modest compared with typical BP meds (context matters).Salt sensitivity varies: roughly ~30% of healthy people and ~40–50% of people with hypertension may be “salt-sensitive” (with higher rates in older adults, women, and some ancestry groups).If you’re salt-sensitive—especially with hypertension—being mindful of sodium is likely worth it. If you’re not, the “must be low-salt for everyone” story is less clear.Practical: Do an N-of-1 salt sensitivity test Measure home BP daily (or a few times/day) for a weekGo lower-sodium for 1–2+ weeks (at least within guidelines, possibly lower)Track BP changeAdd salt back and watch what happensOptional: repeat the low-salt phase for confirmation  If BP shifts meaningfully (often ~3–5 mmHg+), you may be salt-sensitive.Food reality check (why sodium adds up fast) ~10% of a 2,300 mg/day sodium “budget”: 2 slices bread, 1 Tbsp ketchup, or a pinch of salt~1/3: 1 cup canned soup, 1 slice pizza, or a Big Mac~1/2: frozen lasagna, a few deli slices, or a 6” cold-cut sub  Cooking mostly from whole foods makes staying lower-sodium much easier.Studies & resources mentioned (links embedded) CDC hypertension awareness/treatment/control stats: https://www.cdc.gov/nchs/products/databriefs/db511.htm Hypertension outcomes review (risk of events/death): https://pmc.ncbi.nlm.nih.gov/articles/PMC8292050/ Population sodium/BP overview (JACC): https://www.jacc.org/doi/10.1016/j.jacc.2019.11.055 DASH-Sodium trial (NEJM): https://www.nejm.org/doi/full/10.1056/NEJM200101043440101 Sodium restriction meta-analysis (BP/outcomes): https://pmc.ncbi.nlm.nih.gov/articles/PMC12624901/ Salt sensitivity overview (AHA/Hypertension): https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.123.17959 Heart failure trials/meta (salt restriction): https://www.ahajournals.org/doi/10.1161/CIRCHEARTFAILURE.122.009879 Salt substitute trial (NEJM): https://www.nejm.org/doi/full/10.1056/NEJMoa2105675 Call to action Are you going to run your own N-of-1 salt test?

    #63 The Million Dollar Question: Which Health Predictions Actually Help You Live Longer?

    Can you predict when “bad things” will happen to your health—and more importantly, can you do anything about it? In this episode, I break down which prediction tools actually help you live long and well (because you can act on them), and which ones are mostly expensive fortune-telling. Joined by cardiologist Dr. Anthony Pearson (author of The Skeptical Cardiologist), we dig into heart-risk calculators, dementia genetics, and why biological age clocks aren’t ready for prime time. Guest: Dr. Anthony Pearson, cardiologist and writer of The Skeptical Cardiologist (Substack) Key topics & takeaways Why “prediction” only matters if it changes what you do—and improves real outcomes.A red flag to watch for: is the person promoting the tool also selling the test, supplements, or “hacks” to fix it?A sobering reality check: even doctors’ YouTube claims often lack strong evidence (and the least evidence-based content gets more views).Heart disease risk equations: the gold standard in prediction because we can reduce risk factors (BP, LDL/ApoB, smoking, diabetes) and clinical trials show outcomes improve.But even good tools miss people: a study of 65-year-olds who had heart attacks found many were labeled “low risk” beforehand.Dementia genetics (ApoE): ApoE4 raises risk (especially E4/E4), but it’s not destiny. You can’t change genes—so the value of testing depends on whether it motivates healthy behaviors or creates anxiety.Biological age clocks: fascinating research, messy consumer product. Different tests disagree, repeat testing can vary wildly, and most importantly—no proof that “lowering” a clock improves health outcomes or longevity.
