93% or more of American adults are metabolically unhealthy by conventional thresholds — and by optimal ranges the figure is closer to 99% — because the healthcare and ultra-processed food industries profit from chronic disease, not from its prevention.
2
All the major chronic diseases of the modern West — heart disease, diabetes, Alzheimer's, cancer, depression, infertility, PCOS, erectile dysfunction — are different cell-type manifestations of one underlying problem: mitochondrial dysfunction and the cellular energy crisis it creates.
3
The five freely available metabolic biomarkers (fasting glucose, triglycerides, HDL, blood pressure, waist circumference) are the minimum dashboard every person should read themselves — optimal thresholds are substantially tighter than the 'normal' ranges doctors cite.

Food is molecular information that literally 3D-prints the next version of your body; choosing nutrient-dense, unprocessed food from healthy soil is the highest-leverage single intervention for restoring cellular energy production.

Read your own five metabolic biomarkers from your last annual physical
WhatPull your last blood panel and check five numbers: fasting glucose, triglycerides, HDL cholesterol, blood pressure, and waist circumference. Compare to both the conventional thresholds and the optimal thresholds.
WhenToday, from any existing blood panel. Repeat at least annually.
DoseOne-time review takes 10 minutes. Repeat annually or whenever dietary/lifestyle changes are made.
For whomEveryone, particularly the 93%+ of American adults who fall outside optimal ranges.
WhyThese five markers directly reflect mitochondrial function and cellular energy production. High triglycerides signal that excess glucose is being converted to fat because cells cannot process it. Elevated fasting glucose signals insulin resistance — itself a protective mechanism for overloaded mitochondria.
CaveatsConventional 'normal' thresholds are not optimal. Optimal targets: fasting glucose less than 85 mg/dL, triglycerides less than 70 mg/dL, HDL greater than 50 (women) / greater than 40 (men), blood pressure approximately 110/70, waist less than 32–34 inches (women) / less than 35 inches (men). If on medication for any of these, you are already outside the metabolic health threshold.
Means: 'If your fasting glucose is under 100, triglycerides under 150, HDL above 40 for men, above 50 for women, waist circumference less than 35 inches for women, less than 40 inches for men, and blood pressure less than 130 over 85, and you are not on medication — you are in the 6.8% categorized as metabolically healthy.' But this is the conventional floor, not the ceiling. Hyman adds: 'Your triglycerides should not be 150, they should be in the 70s. Your blood sugar shouldn't be 100, it should be in the 80s. Your blood pressure shouldn't be 130/80, it should be like 110/70.' The implication: if you meet the conventional threshold, you may still be far from optimal.
Mechanism
Fasting glucose rises when insulin resistance blocks glucose entry into cells. Triglycerides rise when the body converts excess blood glucose to fat for storage. Both reflect mitochondrial overburden — the cell's protective response to energy-conversion failure.
Five of the signals from your body that there may be bad energy brewing are your levels of fasting glucose, triglycerides, HDL cholesterol, blood pressure, and waist circumference.
Also said
“By the time your blood sugar starts going up this can be going on for decades. The insulin resistance... is a better way to test for it.”— Fasting glucose is a lagging indicator — fasting insulin rises first, often a decade before glucose becomes abnormal.
Use continuous glucose monitoring for real-time metabolic feedback
WhatWear a continuous glucose monitor for at least two to four weeks to observe blood sugar response to specific meals, sleep quality, stress, and exercise. Look for minimal glucose spikes and consistent time-in-range.
WhenAny time you want to understand your personal metabolic response to food and lifestyle choices. Especially valuable when adopting a new dietary pattern.
DoseA minimum two-week wear reveals both postprandial patterns and fasting baseline trends.
For whomAnyone wanting to personalize their diet. Critical for people with elevated fasting glucose, triglycerides, or waist circumference.
WhyBlood glucose is the fastest, most direct proxy for mitochondrial energy metabolism that can be measured non-invasively in real time. Postprandial spikes that stay elevated reflect insulin resistance. Low, flat responses to a given food confirm that food is a good metabolic match for that individual.
CaveatsCGM reflects glucose only — other metabolic parameters (fasting insulin, triglycerides, inflammatory markers) require blood tests. CGM data can cause anxiety in people prone to health obsessiveness; use it as information, not judgment.
Means co-founded Levels Health specifically to democratize CGM outside the clinical setting. The platform pairs the sensor with food logging and gives users direct feedback on glycemic response. Hyman describes a patient who used CGM and discovered his blood sugar was dysregulated despite a perfect diet and lifestyle — the culprit turned out to be environmental toxins, identified only because the CGM made the persistent dysregulation undeniable. Without CGM, the toxin hypothesis would never have been pursued.
Personal experience
Means: 'If I wake up in the morning and I look at my continuous glucose monitor and I am in the very healthy normal range with minimal glucose spikes over the past 24 hours and I wake up and I feel incredible with no symptoms — I know that my strategy is working.'
We now have the tools at our disposal at home to understand more about our bodies and how our personal choices are working for our biology than we've ever had in human history.
Run a comprehensive metabolic biomarker panel beyond the standard five
WhatAdd fasting insulin, high-sensitivity CRP, uric acid, liver enzymes (ALT/AST), and lipoprotein fractionation (ApoB, LDL particle count) to the standard five-marker metabolic screen.
WhenAt baseline and annually, or more frequently when optimizing. Especially critical before relying on conventional 'normal' results that may mask early dysfunction.
DoseOne blood draw. Function Health's basic panel includes all of these and approximately 100 additional markers.
For whomAnyone who has received a 'normal' panel from their physician but still has symptoms, excess weight, or family history of metabolic disease.
WhyThe standard five metabolic syndrome criteria are lagging indicators — they shift only after years of insulin resistance. Fasting insulin rises first. High-sensitivity CRP reflects systemic inflammation. Uric acid rises with fructose overload and is an early metabolic distress signal. ApoB is a better cardiovascular risk predictor than LDL-C. None of these appear on a standard annual physical.
CaveatsLess than 1% of Quest Labs tests include insulin or lipoprotein fractionation — most doctors will not order these proactively. Patients may need to request them specifically or use a direct-to-consumer service.
Hyman: 'I asked the head of Quest Labs — how many of your lab tests include insulin? Less than 1%. How many include lipoprotein fractionation? Less than 1%. But these are the most essential things you need to know and we're completely blind to it.' Means: 'By the time your blood sugar starts going up this can be going on for decades. The insulin resistance is a better way to test for it. Go deeper into fasting insulin and high-sensitivity CRP.'
Mechanism
Insulin resistance typically precedes overt hyperglycemia by 10–20 years. During that period, fasting insulin is elevated while fasting glucose remains normal — the pancreas compensates by secreting more insulin to overcome cellular resistance. Only when beta-cell capacity is exhausted does glucose rise.
The next level is to go deeper into other biomarkers that can give you even more nuance — things like fasting insulin and high-sensitive CRP, liver function tests, and uric acid.
Eat the five elements of Good Energy eating at every meal
WhatStructure meals around five functional food categories: fiber, antioxidants, healthy protein, omega-3 fats, and probiotic/fermented sources. Any dietary pattern can deliver these if built around real, unprocessed foods.
WhenEvery meal. Use the grocery store as a pharmacy — hunt for the functional categories rather than following a rigid meal plan.
DoseOngoing. Within a few days, cell membrane fatty acid composition begins shifting. Within weeks, inflammatory markers improve.
For whomAnyone rebuilding metabolic health. Dietary pattern agnostic — works equally for plant-forward and animal-forward approaches.
WhyThese five categories provide the structural and functional information cells need: fiber feeds the microbiome and slows glucose absorption; antioxidants modulate gene expression; protein provides amino acids for mitochondrial enzymes; omega-3s correct the pro-inflammatory omega-6:omega-3 ratio; probiotics maintain the gut barrier that prevents endotoxin-driven inflammation.
CaveatsThe framework requires avoiding ultra-processed foods regardless of macronutrient framing. Keto chips made from seed oils and vegan protein bars full of refined additives are not in any of these five categories.
Means: 'If you can learn basically your favorite foods in each of those categories and just craft your meals based on those principles, which can come from any dietary pattern, you are going to give your cells the building blocks and the information to have good structure.' Hyman adds the practical heuristic: when he walks into a grocery store he is hunting — specifically targeting cruciferous vegetables (isothiocyanates for antioxidant gene expression), shiitake mushrooms (beta-glucans), phytochemical-rich berries, omega-3-rich sardines, and olive oil with oleocanthal. Everything else fades into the background.
Mechanism
Isothiocyanates in cruciferous vegetables activate Nrf2, the master antioxidant transcription factor. Curcumin in turmeric modulates NF-kB inflammatory signaling. Omega-3 EPA/DHA incorporate into cell membranes and shift eicosanoid production toward resolution rather than initiation. Probiotic foods and fiber maintain intestinal permeability, preventing lipopolysaccharide translocation which is a direct trigger for insulin resistance.
The five elements of good energy eating — fiber, antioxidants, healthy protein, omega-3 fats, and probiotic sources. If you can learn your favorite foods in each of those categories you are going to give your cells the building blocks and information to have good structure.
Source food from farmers markets and good-soil producers as the primary upgrade
WhatPrioritize food from farmers markets, CSAs, and producers using regenerative or organic practices — not as a luxury add-on, but as the primary sourcing strategy. Shift budget away from packaged goods toward raw ingredients from traceable sources.
WhenAs soon as possible. Even partial adoption — one farmers market trip per week — provides meaningful nutrient density improvement.
For whomEveryone. Especially critical for people relying on a high-calorie but micronutrient-poor modern diet.
WhyDepleted soil produces food with fewer micronutrients and phytochemicals per calorie. Cells are blind — they can only use what is floating around them. If a cell needs selenium to build a glutathione antioxidant enzyme, and the soil-depleted food it received contains no selenium, that enzyme cannot be built regardless of how many calories are consumed.
CaveatsFarmers market food is not always organic or regeneratively farmed — asking about soil practices and pesticide use matters. For people in food deserts, frozen organic produce is a viable alternative to fresh conventional.
Means: 'The closer you can get to food that is from good soil — so it's enriched with more nutrients — and unprocessed, the more of that 70 metric tons of information that you're building yourself from will be helpful material. Right now it's not only empty, it's harmful.' The 70-metric-ton figure: we take in approximately that mass of food matter in a lifetime, and it is constantly being turned into and 3D-printing the next version of the body. The quality of that material directly determines the quality of the output.
The closer you can get to food that is from good soil — enriched with more nutrients — and unprocessed, more of that 70 metric tons of information that you're both building yourself from and that is dictating the function of your body will be helpful material.
Treat yourself as the CEO of your own health using N-of-1 data
WhatStop delegating health decisions entirely to doctors, the science, or influencers. Use personal biomarker data (CGM, comprehensive blood panels, wearables) alongside symptom tracking to evaluate what works for your biology specifically. Change one variable at a time and observe the effect.
WhenImmediately. Start by reading your existing blood panel with Good Energy optimal thresholds as a reference.
DoseOngoing. The N-of-1 experiment has no endpoint — it is a permanent operating mode.
For whomEveryone managing chronic symptoms, attempting dietary changes, or navigating a healthcare system that has failed to resolve their condition.
WhyThe NIH classifies N-of-1 studies (yourself as your own control) as the highest level of evidence. This is the one study design that is free, personalized to your genetics and microbiome, and cannot be funded or biased by industry. No population-level RCT can tell you how your specific cells respond to a specific food — only your own biosensors can.
CaveatsN-of-1 experimentation requires literacy in what biomarkers to measure and what direction of change is meaningful. The goal is not to replace doctors but to arrive at appointments with data rather than symptoms alone.
Means: 'I say don't trust doctors, don't trust the science, don't trust influencers — trust yourself... We are living in an age where the incentives are working against us. But in the last three years we now have the tools at our disposal at home to understand more about our bodies than we've ever had in human history.' Hyman: 'The highest level of evidence according to the National Institute of Health is N-of-1 studies — meaning you are your own control. You do something, you change something, you see what happens.'
Don't trust doctors, don't trust the science, don't trust influencers — trust yourself. We literally can have the answers and don't need to give away our trust to other people outside of us that profit off our confusion.
Advocate for systemic food policy change as a personal health intervention
WhatVote based on candidates' positions on food policy. Contact representatives directly about: removing added sugar from school lunch programs, eliminating industry conflicts of interest from FDA/USDA advisory boards, and reforming the farm bill to subsidize nutrient-dense food rather than commodity crops turned into refined carbohydrates and seed oils.
WhenOngoing. Electoral cycles provide the highest-leverage intervention points.
For whomAll citizens and taxpayers. Especially parents of school-aged children and voters in agricultural states.
WhyIndividual dietary change is necessary but insufficient when the policy environment makes ultra-processed food artificially cheap and real food artificially expensive. Farm bill subsidies make nutrient-poor commodity crops cheaper per calorie than vegetables. Industry-captured regulatory bodies embed unhealthy guidance into institutional systems.
CaveatsPolicy change is slow relative to personal dietary change. Both levels of intervention are necessary simultaneously.
Means articulates the quadruple-payment structure: every American pays for cheap processed food four times — at the store, through farm bill subsidies, through environmental remediation, and through Medicaid/Medicare for the resulting chronic disease. 'The food industry spends more on lobbying than any other industry, including oil.' Hyman adds: 'The person who is in their office every single day lobbying is the person the representative is going to get the most information from — and right now that is the food industry.'
We've got to change the farm bills to incentivize the production of non-toxic, real, nutrient-dense food rather than toxin-covered commodity crops that get turned into processed food.

Less than 1% of Americans are at truly optimal metabolic health
~18 min
The commonly cited 6.8–7% figure for 'metabolically healthy' adults is based on conventional thresholds, not optimal ones. Casey Means argues that when you tighten the targets — triglycerides into the 70s, fasting glucose in the 80s, blood pressure 110/70 — the fraction who are genuinely optimal collapses to under 1%.
Why this matters: The public debate about metabolic health severity is systematically distorted by using thresholds calibrated to 'when to medicate' rather than 'what is optimal.' The true scale of the crisis is an order of magnitude worse than reported.
Background
The 93% figure comes from the NHANES trial (National Health and Nutrition Examination Survey), which defines metabolic syndrome by high cholesterol, high blood sugar, high blood pressure, overweight, or prior cardiovascular event.
Hyman's Function Health platform has tracked over three million biomarkers from a health-forward early-adopter population. Even in this group, 95% had elevated lipid particles, 89% had elevated small LDL particles, and 56% had high ApoB. Means's point is that the NHANES criteria represent the threshold for pharmaceutical intervention, not for health. By optimal standards — triglycerides in the 70s not 150, glucose in the 80s not 100 — the fraction who are actually thriving is tiny, and the epidemic is effectively universal.
I'd guess it's less than 1% of Americans are actually optimally healthy.
Also said
“93% of us have high cholesterol high blood sugar high blood pressure have had a heart attack or stroke or are overweight. 93% of us.”— Establishes the baseline crisis figure before tightening to optimal thresholds.
All modern chronic disease is one disease: mitochondrial energy failure expressed in different cell types
~25 min
Casey Means frames the full spectrum of Western chronic disease — from PCOS to Alzheimer's, cancer to depression, erectile dysfunction to premature blindness — as a single underlying process: mitochondria failing to convert food energy to ATP, expressing differently based on which cell type is underpowered.
Why this matters: The fragmented-specialties model of medicine treats these as unrelated diseases. The mitochondrial-energy-crisis model explains them all with a single mechanism and a single family of root-cause interventions.
Background
Means left a Stanford-trained surgical career specifically because she could not reconcile the disconnect between the specialization model and what she was observing about systemic metabolic dysfunction.
Means uses the analogy: we have over 200 cell types, each with a distinct job. When the mitochondria underpowers a retinal cell, you get diabetic retinopathy. When it underpowers a myocyte, you get cardiomyopathy. When it underpowers an ovarian cell, you get PCOS. When it underpowers a neuron, you get depression or Alzheimer's. These are not different diseases — they are one disease with a different address. The conventional system invented 40+ specialties to manage the addresses. Functional medicine asks why every address is sick at the same time.
All of the symptoms and diseases that we are facing and suffering from in the modern Western world are fundamentally the same disease. They are diseases of metabolic dysfunction, insulin resistance.
Also said
“It can look like polycystic ovarian syndrome, erectile dysfunction, fatty liver disease, stroke, heart disease, Alzheimer's dementia, cancer, depression, anxiety, migraine, fibromyalgia — it can look like almost anything.”— Completes the inventory of cell-type manifestations of the same mitochondrial failure.
The food and healthcare industries form a $10+ trillion revolving door that profits from chronic disease
~42 min
Every institution in America that touches health — hospitals, pharma, insurance, ultra-processed food companies — makes more money when people are sick. Fast food companies and insurance companies are co-investors. Ultra-processed food creates the patient pool; the healthcare system monetizes it.
Why this matters: Understanding this structural dynamic is the prerequisite for trusting one's own data over expert consensus, which is a core message of Good Energy.
Background
U.S. healthcare spend grew from $1.6 trillion in 2000 to $4.3 trillion by the time of recording — roughly 25% of GDP and the fastest-growing industry in the country.
Means describes the devil's bargain: food companies profit by making products people are biologically addicted to. Healthcare profits when those same people present with chronic disease. Pharmaceutical companies fund 60% of mainstream media advertising, which suppresses both investigative journalism and TV segments about food-health connections. Hyman recounts being uninvited from the Today Show after proposing a 100-calorie comparison of Oreo snack packs versus blueberries — the segment was killed because it implied processed food was harmful.
Every single institution in America that touches our health makes more money when we are sick and they make less money when we're healthy.
Also said
“The fast food industry was invested in by the insurance companies... recently the fast food makers and processed food makers called the CEO of Novo Nordisk stressed about losing their market — or stomach share.”— Concrete example of the financial integration between the food and healthcare industries.
Industry-funded research systematically corrupts nutrition science
~65 min
Studies on artificial sweeteners, dietary fat, and other contested topics are routinely funded by the American Beverage Association, Coca-Cola board members, and pharmaceutical companies. The evidence hierarchy itself is structurally biased toward pharmaceutical interventions because only drugs can have a placebo-controlled trial design.
Why this matters: Teaches a practical heuristic: before accepting any nutrition study, check who funded it. The design constraint that makes RCTs the gold standard also makes lifestyle interventions systematically un-studyable by that standard.
Background
Means refers to a specific sweetener study funded by the American Beverage Association (formerly the American Soda Pop Association) and another authored by a Coca-Cola researcher on the board of the International Sweeteners Association.
The structural problem: a randomized controlled trial requires a placebo, which requires a pharmaceutical. Dietary and lifestyle interventions cannot be blinded. So the hierarchy of evidence is built around a study design that, by construction, favors drugs over food. Hyman: 'The first thing you look at is who funded the study. What are the conflicts of interest?' Means: 'When 95% of the people who made the USDA food guidelines have a conflict of interest with the processed food industry, of course there's going to be more leniency towards those foods.'
You have to be very smart and the first thing you look at is who funded the study, what are the conflicts of interest.
Also said
“Baked into the hierarchy of evidence is a bent towards medication... if you're doing exercise or a dietary intervention you can't have a placebo.”— Explains the structural, not just financial, corruption of nutrition evidence hierarchies.
Food quality changes cell membrane composition within days
~115 min
Cell membranes are made of dietary fatty acids. The ratio of omega-3 to omega-6 fats in a person's membranes is almost entirely determined by what they eat — and shifts in just a few days. The inflammatory mediators the immune system secretes are literally made by snipping fatty acids off cell membranes.
Why this matters: Gives a concrete, fast-acting mechanism for why food quality matters at the cellular level — not abstract wellness language, but molecular membrane biochemistry that changes within days of dietary change.
Background
Means frames this through her Good Energy book's first chapter on how food determines structure and function. The omega-3:omega-6 ratio has shifted from roughly 1:1 in ancestral diets to 1:15–20 in the modern American diet, driven almost entirely by industrial seed oils.
The membrane composition cascade: you eat more omega-6 (from seed oils) → more omega-6 fatty acids in cell membranes → when the immune system snips a fatty acid off the membrane to make an eicosanoid → it makes a pro-inflammatory eicosanoid (from omega-6) instead of a pro-resolving one (from omega-3). The same food choice that degrades membrane quality also degrades immune resolution. Nutrigenomics compounds this: every bite of food changes gene expression — curcumin from turmeric modulates inflammatory gene expression, isothiocyanates from cruciferous vegetables modulate antioxidant gene expression.
In just a few days we can change the composition of our cell membranes by what we're actually putting in our mouths and then that has a huge trickle-down effect for how our cells fundamentally function and how our immune system functions.
Also said
“A lot of the inflammatory mediators our immune system makes are actually done by snipping fatty acids off our cell membranes and turning them into inflammatory chemicals.”— The molecular mechanism linking dietary fat quality directly to inflammation rate.
Environmental toxins are an under-recognized driver of insulin resistance
~80 min
Petrochemicals, plastics (BPA, phthalates), PCBs, heavy metals (arsenic), and pesticides are documented in the literature as insulin resistance drivers — but endocrinologists almost never test for them, and no pharmaceutical solution exists, so they are systematically ignored by the system.
Why this matters: Expands the root-cause model beyond food and exercise to environmental toxin exposure — critical for the patients who 'do everything right' but cannot normalize blood sugar.
Hyman describes a patient who ate well, exercised, did not drink, yet had persistently dysregulated blood sugar. After a cellular detoxification protocol targeting heavy metals and petrochemicals, blood sugar normalized for the first time. Means: 'It's not only what we eat — it's petrochemicals, plastics, BPA, PCBs, heavy metals, arsenic. We know this is linked to diabetes. This is in the literature.' The conventional endocrinology visit does not include a toxin panel, and the research funding system does not fund detoxification protocol trials.
It's not only what we eat, it's petrochemicals, plastic, phthalates, PCBs, BPA, heavy metals — all these things, arsenic — all this we know is linked to diabetes. This is in the literature.
The USDA dietary guidelines scientific advisory board's recommendation was overridden by politicians
~185 min
The scientific advisory board for the 2020–2025 Dietary Guidelines for Americans recommended reducing added sugar from 10% to 6% of total daily calories. Political appointees rejected the recommendation. Under George W. Bush, the final determination was changed from a scientific to a political decision.
Why this matters: Concrete recent example of regulatory capture: the science was done, the recommendation was made, and it was explicitly rejected by political decision-makers under food-industry pressure.
Means: 'The people who finalized the guidelines rejected the scientific advisory board's recommendation.' Hyman adds context: when 95% of the advisory board members have conflicts of interest with the processed food industry, even the starting point is compromised. The compounding of industry-funded research, industry-conflicted advisory boards, and political override of scientific recommendations creates a system where the guidelines are structurally incapable of recommending what the science supports.
The scientific advisory board for the guidelines recommended that we decrease the percent of added sugar from 10% to 6% and the people who finalized the guidelines rejected the scientific advisory board's recommendation.
A 'fast food burger' actually costs $100 when all externalities are counted
~192 min
Means argues that the apparent cheapness of ultra-processed food is subsidized four times over: at the register, through farm bill subsidies, through environmental damage to water/air/soil, and through downstream healthcare costs paid by taxpayers.
Why this matters: Reframes the 'healthy food is elitist' argument by showing that cheap processed food only appears cheap because its true costs are socialized. Every taxpayer is paying for UPF whether they eat it or not.
Means: 'You are paying for that food at least four times over. You're paying for the food in the store. You're paying for the farm bill subsidies that made that unhealthy food cheaper. You're paying for the environmental damage of how that food was grown. And you're paying the healthcare dollars for the chronic disease of that food. That Burger is a $100 whether you like it or not.' The farm bill, which subsidizes commodity crops that become refined carbohydrates and seed oils, is the upstream policy lever that makes ultra-processed food artificially inexpensive.
That Burger is a $100 whether you like it or not and we are the voters, we are the consumers, it's no one's responsibility but ours.

Good Energy: The Surprising Connection Between Metabolism and Limitless Health by Casey Means MD
Book Sponsored · disclosed
The primary book discussed throughout the episode — Means's synthesis of the metabolic dysfunction epidemic, its causes, biomarker monitoring, food principles, and a four-week action plan.
DisclosureCasey Means is the guest and co-author; Hyman provided a blurb for the cover. Explicit promotion throughout the episode.
Hyman describes it as 'a paradigm-shifting book because it helps us understand what's really at stake here, what the problem is with the why.' The book covers all seven metabolic health vectors (food, stress, sleep, movement, toxin exposure, light exposure, temperature), provides quizzes for each, and includes detailed guidance on reading your own biomarkers. Means's central argument: the solution is simpler than the system wants you to believe, and the complexity is manufactured to maintain dependency.
Good Energy, the surprising connection between metabolism and Limitless Health — it's one of those books that I think is a paradigm-shifting book.
Hyman's book on the systemic food policy failures driving the metabolic health epidemic — farm bills, regulatory capture, USDA conflicts of interest, and actionable advocacy.
DisclosureHost's own book, referenced as the companion policy-focused text.
Means explicitly directs listeners: 'Everyone read Food Fix.' Hyman describes it as covering what executive orders could change tomorrow — removing sugar from school lunches, decoupling the FDA and USDA from industry funding, restructuring farm subsidies. The book makes the policy argument that individual dietary change is necessary but insufficient without systemic reform.
I wrote a book called Food Fix and we talked about some of the policy issues — some things can be done with executive orders that can fix things tomorrow.
Comprehensive blood-testing platform giving individuals access to 100+ biomarkers including the advanced metabolic markers (fasting insulin, ApoB, hs-CRP, uric acid) that standard annual physicals omit.
DisclosureHyman is an investor and co-founder.
Hyman: 'Function Health allows people to go deep inside of the center of the cell and know: is it working?' The platform has tracked over 3 million biomarkers. Key finding: even in a health-forward early-adopter population, 95% had elevated lipid particles and 89% had elevated small LDL particles. The service is positioned as the democratization of precision diagnostics — getting the markers that cardiologists use for high-risk patients to every individual who wants them.
vs alternatives
Standard Quest Labs annual physical includes fewer than 1% of tests with insulin or lipoprotein fractionation. Function Health is the only consumer-facing platform Hyman and Means recommend as a complete metabolic picture.
Function Health allows people to go deep inside of the center of the cell and know: is it working?
Continuous glucose monitor pairing service that connects CGM sensors to an app for food logging, glucose trend analysis, and metabolic scoring. Enables real-time N-of-1 dietary experimentation.
DisclosureCasey Means co-founded Levels Health. Disclosed mid-episode.
Means describes Levels as the democratization of real-time metabolic feedback. The combination of CGM data with food logging allows users to discover their personal glycemic responses — which vary significantly between individuals for the same food — and make evidence-based dietary decisions without waiting for annual bloodwork. Hyman describes using it with patients to identify non-obvious root causes (environmental toxins in one case) that a standard panel missed.
Levels Health is how you can get continuous glucose monitors to really understand your own metabolic health and be empowered to know how your diet and lifestyle is affecting you.

Two-sentence demolition of the appeal-to-authority model in nutrition and health. No other animal outsources its food choices to specialists and no other animal has an obesity/diabetes/Alzheimer's pandemic.
You need to load the body with the highest quality food possible — unprocessed from good soil — because you are going to increase the probability that those little cells are going to have the right thing floating around them to do what you want to do, which is be healthy and not be sick.
The cellular-blindness insight: cells cannot reach for what is not there. The quality of what floats around them is entirely determined by what you put in your mouth.
The system profits off you being confused about what to do. The more research we're publishing on PubMed about nutrition and fitness, the sicker we're getting.
