Introduction: Mindsets At The Mind–Body Interface
Andrew Huberman introduces Dr. Alia Crum, her roles at Stanford, and the central theme: how mindsets—our core beliefs about stress, food, exercise, and medicine—deeply influence physiology and performance. He previews key examples, such as allergy treatments and drug side effects shaped by expectations, and frames the episode as a toolkit for examining one’s own mindsets.
- •Crum is a tenured psychology professor, clinical psychologist, and former Division I athlete who directs the Stanford Mind & Body Lab.
- •Her work shows beliefs about food, stress, exercise, and medications can alter biological responses and treatment outcomes.
- •Listeners are invited to reflect on their own mindsets about stress, food, exercise, relationships, etc. to make the conversation more actionable.
- •Huberman emphasizes the importance of mindset research for daily routines, performance, and well-being.

Defining Mindsets And Their Role In Simplifying Reality
Crum defines mindsets as core assumptions that orient expectations, explanations, and goals in specific domains, using examples like stress-is-enhancing vs. stress-is-debilitating. She connects this to Carol Dweck’s growth vs. fixed mindsets about intelligence and explains how mindsets simplify complex realities but can substantially influence motivation and outcomes.
- •Mindsets are simplifying assumptions about domains such as stress, intelligence, food, medicine, and exercise.
- •Growth vs. fixed mindset: believing intelligence is malleable tends to increase effort, resilience, and learning behaviors.
- •Mindsets help us navigate complexity but are not neutral; they shape what we attend to, how we interpret events, and what we do.
- •Crum’s lab expands mindset research beyond motivation to include physiological effects.
- 27:30 – 38:40
Milkshake Study: Beliefs About Food Alter Hunger Hormones
Crum describes her Yale milkshake experiment showing that beliefs about a food’s caloric content change the body’s ghrelin response even when the actual shake is identical. Expecting an indulgent, high-calorie shake led to a steeper ghrelin drop—greater satiety—than expecting a sensible, low-calorie shake, reshaping her own views on dieting and deprivation.
- •Participants consumed the same ~300-calorie shake twice but were told once it was 620-calorie “indulgent” and once a low-calorie “sensible” shake.
- •Ghrelin, the hunger hormone, dropped threefold more when participants believed the shake was indulgent.
- •Believing you’re “dieting” or eating something insufficient can keep the body in a physiologically hungrier state, potentially slowing metabolism.
- •An “I’m having enough, this is satisfying” mindset around healthy eating may be metabolically more adaptive than a chronic deprivation mindset.
- •This was an early demonstration that beliefs about food can cause measurable physiological changes, not just shifts in taste or self-reported fullness.
- 38:40 – 45:20
Placebo, Nocebo, And Belief Effects Beyond Sugar Pills
The conversation broadens to placebo and nocebo effects, clarifying that belief effects extend far beyond inert pills and into everyday behaviors like eating and exercising. Crum explains her framework: placebo responses arise from social context, beliefs, and the body’s natural capacities, and she introduces nocebo effects where negative expectations generate negative outcomes.
- •Traditional placebo research shows belief alone can change asthma, blood pressure, pain, and immune function.
- •Most clinical trials compare drug vs. placebo but rarely placebo vs. doing nothing, obscuring pure belief effects.
- •Crum prefers the broader term “belief effects,” since many of her interventions are not literal placebos but reframings.
- •Nocebo effects: being told about side effects or risks increases the likelihood and intensity of those experiences.
- •Belief, attention, and physiology jointly shape symptoms and treatment responses.
- 45:20 – 55:20
Exercise Mindsets: Housekeepers, ‘Enoughness,’ And Mortality Risk
Crum presents the hotel housekeepers study, where simply re-labeling their work as exercise improved health markers without measurable behavior change. She then discusses large-scale data showing that perceiving oneself as less active than others predicts higher mortality, independent of actual activity, and reflects on her own shift from chronic “never enough” exercise thinking.
- •Hotel housekeepers were expending significant energy but mostly believed they “didn’t exercise.”
- •Telling half of them their work met exercise guidelines, and explaining associated benefits, led to weight loss and ~10-point systolic blood pressure reductions over 4 weeks.
- •In national datasets, self-perceived activity level relative to others predicted death rates over 21 years, sometimes more strongly than actual activity levels.
- •Feeling chronically “insufficient” in activity can be harmful; a mindset of “getting enough” seems protective.
- •Public health messaging that many people fall short on exercise may unintentionally demotivate and physiologically harm some individuals.
- 55:20 – 1:08:20
Diet Debates, Social Media, And Mindset’s Role Across Eating Styles
Huberman raises the contentious landscape of diet tribes—plant-based, omnivore, carnivore, fasting—and asks whether mindset effects partly explain why adherents in each camp report feeling great. Crum argues that both objective nutrients and beliefs matter, and that believing in one’s chosen regimen, plus community reinforcement, likely amplifies benefits, while guilt and self-judgment can dampen them.
- •Crum refuses to pick a “best diet” but emphasizes that belief effects likely operate within every eating style.
- •Total dietary impact combines objective nutrient effects with beliefs, social context, and bodily adaptation.
- •Strong positive beliefs about a diet—and alignment with a supportive community—may enhance perceived and real benefits.
- •Conversely, chronic self-criticism about not adhering to a chosen diet can add harmful stress on top of any physiological effects.
- •Crum urges moving away from dualisms: mind vs. body, placebo vs. drug, or single “right” diets.
- 1:08:20 – 1:26:40
Stress Mindsets: From ‘Stress Will Kill You’ To ‘Stress Can Grow You’
Crum recounts how prevailing public health messages paint stress as uniformly harmful, while the scientific literature reveals a more nuanced picture including stress-induced focus, cognitive sharpening, physiological “toughening,” and post-traumatic growth. She introduces the concept of stress-is-enhancing vs. stress-is-debilitating mindsets and describes a corporate experiment where brief videos reframing stress reduced symptoms and improved performance.
- •Public discourse overwhelmingly portrays stress as toxic, but research shows it can also facilitate adaptation and growth.
- •Crum defines stress broadly as encountering or anticipating adversity in pursuit of goals; by definition, it attaches to what we care about.
- •She and colleagues developed a stress mindset measure and found that a more enhancing mindset correlates with better health, well-being, and performance.
- •In a UBS field study during the 2008 financial crisis, nine minutes of stress-is-enhancing video over one week shifted mindsets, reduced physical symptoms, and improved self-rated job performance.
- •Watching stress-is-debilitating videos did not worsen outcomes, likely because that narrative was already deeply familiar; the enhancing narrative provided new, empowering information.
- 1:26:40 – 1:37:30
Navy SEALs, Challenge vs. Threat, And Physiological Pathways Of Stress
Discussing stress mindsets in extreme environments, Crum shares findings from Navy SEAL trainees, one of the few groups that, on average, endorse a stress-is-enhancing mindset. This mindset predicted successful completion of BUD/S and better peer ratings. Huberman and Crum connect these findings to hormonal pathways—like DHEA and testosterone increases under acute stress—and to the idea that mindsets may function as a bridge between conscious appraisal and autonomic physiology.
- •Most populations show a stress-is-debilitating tilt; SEAL trainees uniquely show a stress-is-enhancing tilt on average.
- •Among BUD/S candidates, a more enhancing mindset at baseline predicted higher completion rates, faster obstacle course times, and more positive peer evaluations.
- •A stress-is-debilitating mindset tends to produce “freak out” (hyper-react) or “check out” (deny/avoid) responses; enhancing mindsets prompt “how can I use this?” behaviors.
- •Preliminary data suggest enhancing mindsets correlate with more moderate cortisol responses and higher DHEA under stress, consistent with “toughening.”
- •Huberman notes mechanistic plausibility: stress hormones and neuromodulators (dopamine, epinephrine, anabolic hormones) are biochemically linked and can be channeled toward growth or breakdown depending on context and appraisal.
- 1:37:30 – 1:57:20
Reframing Stress: Acknowledge, Welcome, And Utilize
Crum offers a practical three-step method to transform one’s relationship to stress from something to fight or escape into a resource for action. She emphasizes redefining stress as neutral—arousal tied to meaningful goals—with effects that are not predetermined. Huberman connects this to physiological advantages of the stress response, such as sharpened vision and faster information processing.
- •Step 1: Acknowledge you’re stressed—notice and name it instead of suppressing or denying.
- •Step 2: Welcome it by asking, “What does this stress signal that I care about?” Stress is a marker of values, not just a problem.
- •Step 3: Utilize it—channel the extra energy, focus, and arousal into pursuing the underlying goal instead of trying to extinguish stress itself.
- •Managing or ‘coping with’ stress is often framed as fighting or escaping; leveraging stress seeks to work with it.
- •Huberman notes the stress response is highly generic and comes “for free;” the choice lies in how we frame and employ it.
- 1:57:20 – 2:14:40
Media, Influencers, And The Cultural Construction Of Food Mindsets
Crum turns to the cultural origins of mindsets, especially around food, detailing work from her lab on movies and social media influencers. Analyses reveal that most on-screen and influencer-featured foods are objectively unhealthy, and that unhealthy foods are consistently described with exciting, indulgent language, while healthy foods are framed as boring or depriving—shaping collective mindsets about what’s desirable.
- •Four main sources of mindsets: upbringing, culture/media, influential others (e.g., clinicians), and conscious choice.
- •Brad Turnwald’s work shows that 70–90% of foods depicted in top-grossing movies or by major influencers would fail UK advertising standards for nutritional quality.
- •Unhealthy foods tend to be described using language of excitement, fun, danger, sexiness, and indulgence.
- •Healthy foods, when shown, are often framed as “good for you but boring,” associated with restraint, recovery, or obligation.
- •Audience engagement data show more likes and positive responses for unhealthy-food posts, reinforcing this pattern.
- •Crum argues this culture fuels the mindset that healthy foods are inherently less pleasurable, which can undermine healthy eating efforts.
- 2:14:40 – 2:26:20
Mindsets In Medicine: Side Effects, Allergies, Cancer, And Vaccines
Returning to her roots in placebo research, Crum describes ongoing work integrating mindset interventions with active medical treatments. She highlights a peanut-allergy desensitization study where reframing side effects as signs of the immune system learning reduced anxiety, lowered symptom burden, and improved immunologic outcomes, exemplifying how treatment contexts and explanations can be deliberately designed for better experiences and results.
- •Crum aims to move beyond drug-vs-placebo paradigms to optimizing active treatments by shaping mindsets around them.
- •In a pediatric peanut-allergy protocol, children gradually ingest growing doses of peanut to build tolerance, a process rife with frightening symptoms.
- •Framing side effects as unfortunate but meaningful signs that the body is learning to tolerate peanuts (rather than pure harm) reduced anxiety and symptoms.
- •Immune markers showed better tolerance outcomes in the mindset-reframed group, indicating real physiological benefits.
- •Similar work is being explored in cancer treatment, COVID-19 vaccination, and other medical contexts to enhance efficacy and experience.
- •Crum emphasizes that the key is not mere “positive thinking,” but accurate, mechanistically grounded explanations delivered in empowering ways.
- 2:26:20 – 2:39:10
Meta-Mindsets, Parenting, And Practical Mindset Audits
In closing, Crum introduces the concept of meta-mindset—the ability to notice, evaluate, and intentionally reshape one’s own mindsets. They discuss how to apply this in everyday life and parenting, such as avoiding rigid food rules that inadvertently glorify dessert and vilify vegetables, and instead cultivating mindsets that healthy foods are indulgent and that stress is natural and potentially growth-promoting.
- •Meta-mindset: first recognize that you have mindsets filtering reality, then ask what their downstream effects are.
- •Rather than debating whether a mindset is objectively ‘true,’ assess whether it is helpful or harmful for your health, relationships, and goals.
- •Crum advises treating yourself like a scientist: observe, hypothesize about mindset effects, experiment with alternative frames.
- •In parenting, she prioritizes instilling adaptive mindsets over micromanaging behavior (e.g., not forcing dinner just to earn dessert, which reinforces unhealthy narratives).
- •Her own priorities include: healthy-indulgent mindsets about food, stress-as-natural-and-potentially-enhancing, and later, positive mindsets about physical activity.
- •Huberman commits to regularly asking, “What is the effect of my mindset about X?” as a practical self-audit tool.
- 2:39:10
