Dr. Mark Hyman on Resetting Your Health in 10 Days: Gut Health, Inflammation, Sleep and Supplements

High-Level Overview

Mel Robbins gives listeners a free "appointment" with Dr. Mark Hyman, a functional medicine physician, author of 14 New York Times bestsellers, founder of the UltraWellness Center and head of strategy and innovation at the Cleveland Clinic Center for Functional Medicine. Mel explains she went to his clinic after a breakdown about a year earlier that combined anxiety, grief and menopause symptoms, and says his team's advice made a profound difference. The central idea is that the body is a self-healing, self-repairing system: take out what harms it, put in what it needs, and it knows what to do.

The tone is upbeat, fast-paced and practical, with Mel repeatedly slowing Dr. Hyman down to define terms like inflammation, cruciferous and hormones. The conversation moves from big-picture ideas about food as information and the gut-brain connection to a 10-day eating experiment, specific tools for anxiety and sleep, a short supplement list, hormones, longevity, and a moving testimonial from one of Mel's producers.

The Discussion Explores:

• Functional medicine and the body's built-in ability to heal itself
• Food as information that changes genes, hormones, brain chemistry and the microbiome
• The gut-brain connection, leaky gut and hidden inflammation
• A 10-day reset: what to cut out and what a day of eating looks like
• Anxiety, ADHD and the root-cause approach, including a striking case story
• The five things that cause imbalance and the ingredients the body needs to thrive
• Sleep habits, non-negotiable supplements, magnesium and hormones
• Connection, longevity, health span and testing your own biomarkers

Deep Dive into Main Ideas

The body as a self-healing system

Dr. Hyman says he doesn't really treat disease; he helps the body do what it's supposed to do by getting rid of the bad stuff and putting in the good stuff. Nobody is born with an owner's manual, he jokes, and most of us know our iPhones better than our bodies. Mel compares it to a cut on your hand, which heals without a prescription. Most people don't connect what they eat, the toxins they're exposed to, their stress, sleep and movement with how they feel, and they don't realize how close they are to feeling good.

He makes a striking claim: in group programs combining diet changes with gentle movement and simple body practices, he has seen the average person reduce symptoms across all conditions by about 70% within six days. He jokes about "FLC syndrome" (feeling like crap), and Mel wonders whether so many people are used to feeling bad that they don't know how good they could feel. Dr. Hyman uses the image of standing on your foot your whole life without knowing what it feels like when you get off it. He introduces the exposome, the sum of everything you've experienced, eaten, thought and been exposed to, and says your life isn't a genetic destiny: every cell, your DNA and your microbiome respond to your environment in real time.

Food is information, and the gut is a second brain

When Mel offers the metaphor of food as fuel for a car, Dr. Hyman says it's more exciting than that: "food is not just calories, it's information, it's instructions, it's code" that turns your biology up or down with every bite, changing gene expression, hormones, brain chemistry, the immune system and the microbiome. People rarely connect their food with their mood, asthma, irritable bowel or anxiety.

Mel explains that the brain and gut form from the same embryonic tissue and stay connected, which is why the gut is called the second brain. Dr. Hyman says he discovered this through patients: when he treated their guts and put them on anti-inflammatory diets, they reported better focus, mood and sleep as a side effect. His book The UltraMind Solution is subtitled about fixing your broken brain by fixing your body first. He describes a gut microbe, Akkermansia, which researchers found produces GABA, the calming neurotransmitter that drugs like Valium act on, showing how the right gut bacteria can influence whether you feel calm or depressed.

Hidden inflammation and leaky gut

Inflammation, he explains, is visible on the outside as a sore throat, an infected cut or a swollen knee. But silent inflammation inside the body doesn't turn red; in the brain it can show up as depression, ADD, anxiety or insomnia, and it drives heart disease, cancer, diabetes and dementia. Aging itself involves what he calls inflammaging, one of the hallmarks of aging in his book Young Forever. About 70% of the immune system sits in the gut, so when the wrong bacteria dominate and the gut lining becomes leaky, food proteins and bacteria cross into the body and the immune system reacts, creating inflammation that can show up as asthma, arthritis, depression and more.

Mel shares that her daughter's disordered eating damaged her gut bacteria, leading to bloating and spiking anxiety. Dr. Hyman describes a healthy gut simply: you shouldn't notice it, with no bloating, heartburn or significant gas, and a well-formed bowel movement that takes a couple of minutes. When we eat, we feed trillions of microbes; sugar, starch, processed food, artificial sweeteners, gums and additives harm them.

The 10-day reset

His challenge: "Change your diet and see what happens," not for a year but for 10 days, because "Anybody can do anything for 10 days." Cut out anything from a package, can or box, sugar and sweetened drinks, alcohol, gluten, dairy and processed food; some people may also drop grains and beans for a short time. Eat protein, vegetables, nuts, seeds, berries and healthy fats like olive oil. A sample day: eggs with tomatoes, avocado and olive oil for breakfast; a big colorful salad with canned wild salmon and pumpkin seeds for lunch; and a small piece of fish, chicken or meat for dinner with three-quarters of the plate vegetables. He eats cruciferous vegetables (the broccoli family, including cabbage, collards and Brussels sprouts) daily, saying they help detoxify cells.

Mel adds that your cells are literally built from what you eat, so you choose between cells made from Doritos or from salad and fish. "Your body is the smartest doctor in the room," he says; notice when joint pain, reflux or migraines disappear. If you're already bargaining for artificial sweeteners, he says, that's a sign of biological sugar addiction. He argues it isn't people's fault: blaming individuals with the calories-in, calories-out and moderation narrative is "just a big fat lie" that keeps people ashamed and lets the food industry off the hook, since processed food is made to be addictive.

Anxiety, ADHD and treating root causes

Dr. Hyman compares anxiety and depression to saying you have a headache: they describe symptoms, not causes. The cause might be life stress, trauma, toxins, the microbiome or too much sugar. He starts with lifestyle: the 10-day reset, gentle movement and his "take five" practice, five slow breaths in and out for five seconds each, five times a day, such as before meals. Breathing moves the diaphragm, which the vagus nerve passes through, calming the nervous system and lowering stress hormones.

He tells the story that set him on this path: a 12-year-old with severe ADHD, kicked out of kindergarten and on seven medications, who also had asthma, irritable bowel, headaches, muscle cramps and signs of yeast overgrowth. He was living on junk food and deficient in magnesium, zinc and B vitamins, with gluten sensitivity, bad gut bacteria and some lead. After cleaning up his diet and adding a multivitamin, fish oil, magnesium, vitamin D and probiotics, the boy returned two months later with his ADD and his other symptoms gone, and his handwriting went from illegible to perfect. Mel realizes her son Oakley's story parallels this: diagnosed with severe dyslexia and put on ADHD medication, he stopped the meds in eighth grade and transformed in a school where the cafeteria served only healthy food, even his handwriting changing.

He also distinguishes true allergies, fast and potentially deadly like peanut or bee sting anaphylaxis, from delayed food sensitivities that cause low-grade, long-term symptoms like brain fog. For example, dairy makes him congested and gives him pimples, but sheep or goat products with A2 casein don't.

Five things to remove, and what to add

The body isn't that complicated, he says. The five things that throw it out of balance are bad food, stress (physical or psychological, defined as the perception of a real or imagined threat), toxins, an unhealthy gut with bad bugs, and allergens or sensitivities. The ingredients for health are nutrients (people are often low in omega-3s, vitamin D, B vitamins, iron, zinc and magnesium), balanced hormones, clean air and water, movement, active relaxation such as breathing, yoga, meditation, prayer or journaling, and seven to eight hours of sleep minimum.

Connection, meaning and purpose are also ingredients for health. He says in his book that curing heart disease and cancer would add about five to seven years to life expectancy, while curing loneliness and building connection and purpose would add seven years or more. "Connection is medicine," he says. Mel shares that she's about 30 days without alcohol and finds it life-changing, clearer and more present.

Better sleep

His sleep advice: keep a regular sleep schedule to align with your circadian rhythm; get about 20 minutes of morning light, even on cloudy days, or use a full-spectrum light box, which helps melatonin production later; avoid screens two to three hours before bed or wear blue-blocker glasses, since our bodies evolved without light bulbs; consider magnesium at night; and take a hot bath with Epsom salt, which contains magnesium, and lavender drops, which he says lower cortisol, for about 20 minutes before bed. Keep the bedroom for sleep and sex, with no TV, cool (68 degrees or lower) and dark, using earplugs and eye shades if needed.

Supplements, magnesium and hormones

His non-negotiables, for under a dollar a day: a cleanly made multivitamin without fillers and in bioavailable forms; vitamin D3 taken with food containing fat, roughly 1,000 to 5,000 units (he notes government guidance says up to 4,000 is safe); and fish oil, since he says over 90% of people are deficient in omega-3 fats, which make up the brain and cell membranes and regulate inflammation. Magnesium depends on symptoms: anything irritable, twitchy or spasmy, such as anxiety, palpitations, constipation, muscle or foot cramps and eye twitching can signal deficiency. Soda (through phosphoric acid in dark colas), caffeine, alcohol and stress all cause the body to dump magnesium in urine. Electrolytes like potassium from vegetables and broths also help cramps.

On hormones, he describes them as the body's communication and command systems, controlled by the hypothalamus. Men go through andropause, with lower testosterone, libido and muscle, while women's hormones change every decade, from PMS to perimenopause and menopause. In their 30s and 40s, women face imbalances in sex hormones, thyroid (often underdiagnosed), stress hormones and insulin, which drives belly fat. You don't need to treat each separately; addressing lifestyle and root causes helps all of them reset. When Mel asks about midsection weight despite a healthy lifestyle, he suggests checking thyroid, insulin resistance and testosterone, likening the body to a symphony that needs a conductor.

Testing, longevity and a listener's transformation

For people who can't afford functional medicine care, Young Forever includes questionnaires he says can reveal about 80% of what's going on. He also co-founded Function Health, which lets people order over 100 biomarkers at Quest labs without a doctor's order for about $500, versus what he says would normally cost $15,000, with results interpreted through a functional medicine lens. He wants people to be "the CEO of their own health," adding: "I don't want to manage people's symptoms. I want people to get better." He believes addressing about 10 underlying causes of aging could extend healthy life by decades, and he wants to be riding bikes, horseback riding and making love at 100 or 120, closing the gap between health span and lifespan. Mel's 85-year-old mother-in-law, who skydives and walks five miles a day, is her example.

On probiotics, he says diet matters most: feed your gut fiber, fruits and vegetables, fermented foods like sauerkraut, kimchi and miso, prebiotic foods like asparagus, artichoke, plantain and jicama, and polyphenol-rich foods like green tea, pomegranate and cranberry, which Akkermansia loves. Avoid gut-busting sugar, additives and unnecessary antibiotics, acid blockers and anti-inflammatory painkillers. He cured his own colitis this way. The episode closes with producer Donna, who had severe back pain, bad asthma and 43 allergies until she heard Dr. Hyman's audio program; after changing her diet and exercising, she's off medication, no longer allergic to the studio dogs, and has run 27 5Ks and climbed Mount Washington twice.

Conclusion

Dr. Mark Hyman's message is that much of what makes people feel unwell, from brain fog and anxiety to cramps, poor sleep and inflammation, comes from a handful of fixable inputs: processed food, stress, toxins, an unhealthy gut and sensitivities. The practical starting point is a 10-day reset of whole foods, protein and plenty of vegetables, plus simple habits like five slow breaths, morning light, a consistent sleep schedule and a few basic supplements. Behind the tips is a bigger idea: the body is intelligent and responsive, connection is as powerful as medicine, and by treating root causes rather than managing symptoms, people can feel better within days and extend how many years they stay healthy. As always, the tips are shared as reported and don't replace personal medical advice.
