Chris Hemsworth said“I carry a high-risk Alzheimer's gene, so I lean on exercise, sleep, and stress control to fight back.”

The science saysSupported. Big studies link regular exercise to meaningfully lower dementia risk, though they cannot promise it for any one person.

Verdict: He can't out-run his genes, but he can make them sweat.

Joe Rogan said“Regular sauna sessions can cut your risk of dying and add years to your life.”

The science saysReal but observational. Frequent sauna use is tied to lower mortality in large cohorts, but that is correlation, not proof, and the cold plunge is along for the ride.

Verdict: The sauna science is real. The coffin-dodging guarantee is not.

Tom Brady said“Avoiding nightshade vegetables like tomatoes and peppers lowers inflammation.”

The science saysNo good evidence supports cutting nightshades for inflammation in healthy people. They are nutrient dense, and the TB12 method itself later added them back.

Verdict: Tomatoes are fine. Eat the tomatoes.

Wim Hof said“My breathing and cold method lets you consciously control your immune system.”

The science saysGenuinely mixed. One real randomized trial showed his method can blunt a lab-induced immune response, but it was 24 healthy young men, not proof of everyday immunity.

Verdict: A real PNAS paper, skated way past what twenty-four guys can carry.

Tom Hanks said“Get back to your high-school weight and you essentially beat type 2 diabetes.”

The science saysSupported. A major trial showed significant weight loss put type 2 diabetes into remission for nearly half of people, with bigger losses doing better.

Verdict: His doctor's one-liner is basically a clinical trial protocol.

Jack LaLanne said“Exercise is king and nutrition is queen: together, you have a kingdom.”

The science saysStrongly supported. Decades of large studies tie regular activity and whole-food eating to longer life. Only the juicing he sold outruns the evidence.

Verdict: The kingdom checks out. The science would just decline the juicer.

Cristiano Ronaldo said“I don't touch alcohol, after what it did to my father.”

The science saysSupported. The best modern evidence finds no safe protective level of alcohol, so avoiding it sidesteps a real, dose-dependent risk.

Verdict: There is no safe pour, so the empty glass ages best.

Mick Jagger said“Jagger says daily dancing and gym work, drilled for weeks before a tour, are what keep him fit enough to perform two-hour shows at 80-plus.”

The science saysStrong and consistent: regular physical activity, including aerobic dance, robustly lowers all-cause mortality and supports healthy aging, even when started later in life.

Verdict: The grind he says he dreads is exactly the kind of habit the mortality data rewards.

Rich Roll said“Roll says switching to a whole-food plant-based diet transformed how he felt within a week or two and fueled his endurance career.”

The science saysReasonable: plant-predominant diets are consistently associated with lower cardiovascular and overall mortality in large cohorts, though the dramatic '7 to 10 days' transformation is personal anecdote, not measured outcome.

Verdict: The diet pattern earns its reputation; the one-week miracle is a story, not a study.

Peter Attia said“Attia argues that raising your VO2 max (cardiorespiratory fitness) is one of the most powerful things you can do to lower your risk of dying early.”

The science saysLarge cohort studies consistently link higher cardiorespiratory fitness to substantially lower all-cause mortality.

Verdict: The fitness-mortality link is real and large, but it is association, not proof that raising VO2 max adds years.

Paul McCartney said“McCartney says that beyond his ethical reasons, a health argument entered the picture once he heard that eating a lot of red meat isn't good for you.”

The science saysCohort studies link high red and especially processed meat intake to modestly higher mortality, though the certainty for unprocessed red meat is low.

Verdict: Cutting back on red meat, processed meat most of all, is a reasonable bet, but the size of the personal benefit is modest and uncertain.

Clint Eastwood said“Eastwood credits decades of twice-daily Transcendental Meditation as a tool that helps him manage stress.”

The science saysSmall randomized trials and meta-analyses suggest modest reductions in blood pressure and stress, but the studies are small, often run by TM-affiliated researchers, and results conflict.

Verdict: Meditation is safe and may take the edge off stress and blood pressure, but the longevity case for TM specifically is thin and contested.

Arianna Huffington said“Huffington argues that sleep is the foundation of health and performance, and that thriving has to begin with it.”

The science saysLarge meta-analyses link both short and long habitual sleep to higher all-cause mortality, supporting sleep as a core health behavior.

Verdict: On this one the evangelist is right: chronically short sleep is a real, measurable risk, not a hustle perk.

Christie Brinkley said“Brinkley says being vegetarian gives her a lot of energy and reflects an awareness of food as fuel.”

The science saysPlant-based diets are associated with lower heart disease and mortality risk, but the specific claim that they boost personal 'energy' is not directly established.

Verdict: Good for the heart on the data; the 'energy' part is her experience, not a proven effect.

Jamie Lee Curtis said“Curtis says getting and staying sober from opioids and alcohol is the reason she is still alive.”

The science saysStrong and consistent: alcohol and opioid use are major drivers of early death, and abstaining substantially lowers that risk.

Verdict: Staying sober is one of the few life choices with mortality data this lopsided behind it.

Serena Williams said“Williams says shifting toward a mostly plant-based diet left her feeling no weaker and actually gave her more energy.”

The science saysHealthy plant-based eating patterns are linked in large cohorts to lower cardiovascular and all-cause mortality, though the benefit depends on diet quality rather than the 'plant-based' label.

Verdict: Her plates lean the way the heart data points, even if the energy boost is the part science can't grade for her.

Anthony Hopkins said“Hopkins credits stopping drinking 50 years ago, after a blackout behind the wheel, for the long life he is still living.”

The science saysHeavy alcohol use is a well-established driver of premature death, and large analyses find mortality risk climbs with the amount consumed, so quitting heavy drinking plausibly adds healthy years.

Verdict: The mortality data backs the instinct: for a former heavy drinker, quitting is about as close to a longevity move as a single habit gets.

Cher said“Cher says working out is simply part of who she is and that regular exercise keeps her feeling strong and youthful.”

The science saysStrong and consistent: regular physical activity and muscle-strengthening work are reliably associated with lower mortality and better aging.

Verdict: The science backs the habit, not the headline: lifelong movement tracks with healthier aging, even as good genes and survivorship flatter the picture.

Jared Leto said“Leto credits two decades of a mostly vegetarian/vegan diet plus good sleep for his health and youthful appearance.”

The science saysMixed but leaning favorable: vegetarian diets track with lower ischemic heart disease risk, though the evidence is observational and 'youthful looks' is not a measurable endpoint.

Verdict: A plant-leaning plate and steady sleep are sensible bets, but neither is a documented fountain of youth.

Pink said“Pink says she values being physically strong and trains hard, including multiple daily workouts on tour, as part of who she is.”

The science saysStrong and consistent: regular physical activity and muscle-strengthening work are reliably linked to lower mortality and healthier aging.

Verdict: The strength habit is one of the best-supported bets in this whole series, even if a touring pop star's training volume is more than most people need.

Warren Buffett said“Buffett argues that because six-year-olds have the lowest death rate, eating like one, including five Coca-Colas a day, is the safest way to live.”

The science saysRefuted: large cohort studies tie regular sugar-sweetened soda to higher, not lower, risk of death and cardiometabolic disease.

Verdict: The joke is great and the longevity is real, but the evidence runs the other way: his diet looks like a habit he survived, not one that helped.

Tim McGraw said“McGraw says building a demanding daily workout routine took the place of alcohol after he quit drinking and is what got him healthy and lean.”

The science saysStrong and consistent: regular physical activity lowers all-cause mortality, and cutting heavy drinking reduces health risk, so the combination is well supported.

Verdict: Trading the liquor cabinet for the gym is one swap the long-term data clearly rewards.

Gisele Bündchen said“Bündchen says she stays fit and clear-headed by doing exercise she enjoys outdoors, such as horseback riding, biking and skiing.”

The science saysStrong and consistent: regular physical activity of almost any kind lowers all-cause and cardiovascular mortality and also supports mood and cognition.

Verdict: Choose the movement you will actually keep doing: the data rewards the habit, not the venue.

Martha Stewart said“Stewart says drinking homegrown green juice every morning is an essential part of her diet and contributes to her successful aging.”

The science saysEating plenty of vegetables is strongly tied to better health, but juicing them specifically for anti-aging is not supported and the juice loses much of the fiber of whole produce.

Verdict: The vegetables are doing real work; the word anti-aging is doing the marketing.

Bob Odenkirk said“After his on-set heart attack, Odenkirk says he keeps his heart healthy with regular workouts, statins, and routine check-ins with his cardiologist.”

The science saysFor someone who has already had a heart attack, statins plus regular exercise are among the best-proven ways to lower the risk of another one.

Verdict: This is textbook secondary prevention: do not skip the medicine or the movement.

Shaquille O'Neal said“O'Neal urges people with snoring and daytime fatigue to get evaluated and treated for sleep apnea instead of ignoring it.”

The science saysChronically short sleep and untreated obstructive sleep apnea track with higher mortality, but trials show treatment mainly improves symptoms while its effect on hard heart outcomes hinges on how many hours a night the therapy is actually used.

Verdict: Getting apnea evaluated is genuinely smart, but a treatment only protects you for the hours you actually stick with it.

Kevin Hart said“Hart says running began as preparation for a film role and turned into a permanent lifestyle that keeps him fit.”

The science saysRegular running is consistently associated with lower all-cause and cardiovascular mortality in large cohorts, with meaningful benefit even at modest weekly doses.

Verdict: You don't need to run fast or far to win here: it's the showing-up week after week that does the work.

Michelle Obama said“Obama says she stays fit by mixing weights, kickboxing and lots of cardio, plus some yoga, to keep it fun and avoid boredom.”

The science saysCombining strength training with regular aerobic exercise is among the best-supported strategies for lower mortality and healthier aging.

Verdict: A textbook mix: strength plus cardio is about as evidence-backed as fitness advice gets.

Zac Efron said“Efron says eating purely vegan changed how his body metabolizes food, turns it into energy and how he sleeps, and was great for his routine.”

The science saysWell-planned plant-based diets are linked to lower heart disease and cancer risk, but the specific metabolism, energy and sleep improvements he describes are individual and not established outcomes.

Verdict: Good for the heart on paper: the energy-and-sleep magic is a personal report, not a proven effect.

Bill Clinton said“Clinton says he adopted a near-vegan, plant-based diet after heart problems to maximize his chances of long-term survival.”

The science saysPlant-predominant diets reliably lower LDL cholesterol and are linked to lower cardiovascular risk, making this a well-founded choice for someone with established heart disease.

Verdict: For a high-risk heart patient, a whole-food plant-based shift is one of the better-supported bets you can make.

Woody Harrelson said“Harrelson says he eats mostly raw vegan because cooked meals make his energy drop.”

The science saysA plant-heavy diet has real benefits, but there is no good evidence that raw food specifically boosts energy, and strict raw diets carry documented nutritional risks.

Verdict: The vegan base is reasonable; the 'raw equals more energy' part is folklore, not physiology.

Al Roker said“Roker credits daily walking, alongside a lower-carb diet, with keeping weight off and supporting his health.”

The science saysRegular walking, measured by daily step counts, is consistently linked to lower all-cause mortality and better cardiometabolic health.

Verdict: Sensible and well-supported: walking is one of the most reliably beneficial habits a person can keep.

Ringo Starr said“Starr credits eating broccoli with every meal and blueberries every morning with keeping him young and active.”

The science saysVegetable- and berry-rich diets track with better heart and brain health, but no single food keeps a person young.

Verdict: Good food, oversold benefit: the diet is genuinely healthy, but broccoli and blueberries are not a fountain of youth.

Julianne Moore said“Moore says simple daily habits, hydration, yoga and movement that improves blood flow, limiting sugar and alcohol, and challenging herself intellectually, support her long-term brain health.”

The science saysReasonably supported in direction: exercise that boosts blood flow is one of the better bets for protecting aging cognition, though the softer habits she names are far less proven and no single habit guarantees anything.

Verdict: The blood-flow instinct is sound; the rest is sensible living dressed up as brain hacks.

Nick Jonas said“Jonas says that living with type 1 diabetes has not stopped him from training hard, and that hard physical exercise is a normal part of how he lives with the condition.”

The science saysExercise is recommended for people with type 1 diabetes and improves cardiometabolic risk, though it complicates blood sugar control rather than simplifying it, which is exactly the nuance Jonas gestures at.

Verdict: Correct, and unusually honest about the part that is hard.

Rob Lowe said“Lowe credits stopping drinking and staying inside a recovery community for sustaining his health and life over three decades.”

The science saysCutting alcohol use lowers mortality risk, and strong social ties independently track with longer survival, so both halves of what he describes have real support.

Verdict: Two habits, both backed: less alcohol and more people.

50 Cent said“Despite owning a champagne and cognac business, 50 Cent says he does not actually drink, faking sips to keep a clear head.”

The science saysAvoiding alcohol removes a well-documented driver of cancer, liver and cardiovascular harm, and recent large analyses find no clearly protective level of drinking.

Verdict: Selling the bottle while skipping the drink is, health-wise, the smart side of the trade.

Chris Pratt said“Pratt publicly took on the Daniel Fast, a 21-day Bible-inspired plan of prayer and largely plant-based eating.”

The science saysA short Daniel Fast can nudge cholesterol and blood pressure down over three weeks, but the evidence is one small trial with no long-term or longevity outcomes.

Verdict: A three-week faith fast can move a few numbers, but it is a reset, not a longevity plan.

Kevin Smith said“Smith says that after his near-fatal heart attack he skipped keto and went vegan to lose weight and protect his heart.”

The science saysShifting toward healthful plant-based eating is consistently linked to lower heart-disease risk, and intensive plant-based lifestyle programs have even reversed coronary disease.

Verdict: The heart benefits are real, but it's healthful plant foods and weight loss, not spuds alone, doing the work.

Denzel Washington said“Denzel Washington says staying physically active, mainly through years of boxing, is key to keeping his body in shape as he ages.”

The science saysStaying physically active is one of the most robustly evidence-backed ways to lower the risk of early death.

Verdict: The science is squarely in his corner: keep moving.

Jennifer Hudson said“Jennifer Hudson says she maintains her weight by controlling portions and balance rather than by depriving herself.”

The science saysPortion size has a real, measurable effect on how much people eat, so controlling it is a sound weight-management strategy.

Verdict: Portions do the heavy lifting: the science backs her plate.

Angela Bassett said“Bassett says it is important to keep moving, and that prioritizing movement and health now shapes how well we age.”

The science saysStrongly supported: regular physical activity is one of the best-documented ways to lower all-cause mortality and preserve function with age.

Verdict: Keep moving: the science backs her plainly.

Viola Davis said“Davis says that after a prediabetes diagnosis she changed her diet and exercise, and that lifestyle choices are within a person's power to prevent or manage the condition.”

The science saysLarge randomized trials show that diet and exercise sharply reduce progression from prediabetes to type 2 diabetes.

Verdict: The move she credits is one of the best-tested interventions in all of preventive medicine.

Richard Branson said“Branson says looking after his body through daily exercise is what gives him the energy to achieve anything.”

The science saysRegular exercise is one of the most reliably supported health habits there is, though the specific claim that it hands you extra energy is real but smaller than the enthusiasm suggests.

Verdict: Right habit, slightly oversold feeling: the body benefits are rock solid, the energy rush is partly expectation.

Bruce Springsteen said“Springsteen says he stays in touring shape with light weightlifting to stay toned and treadmill walking, having given up running.”

The science saysStrong and consistent: both light resistance training and regular walking are independently linked to lower all-cause mortality, including in older adults.

Verdict: A low-key routine that happens to line up almost exactly with what the longevity data rewards.

Elle Macpherson said“Macpherson says eating an alkaline diet keeps her body lighter, cleaner and full of energy.”

The science saysWeak: the body tightly regulates its own blood pH, and systematic reviews find no good evidence that an alkaline diet prevents disease or changes health outcomes.

Verdict: Eating your greens is great; the pH story bolted onto it isn't what makes it work.

Idris Elba said“Elba says he defines fitness as combat readiness: enough conditioning and strength to last five rounds in a ring.”

The science saysTraining that combines cardiorespiratory conditioning with muscle-strengthening work is among the best-supported lifestyle predictors of lower mortality, even though nobody has studied five-round readiness as an endpoint.

Verdict: A vivid benchmark wrapped around a genuinely well-evidenced habit.

Lewis Hamilton said“Hamilton says switching to a fully plant-based diet made him feel physically better than at any point in his life, with higher energy, more strength in the gym, and no bloating.”

The science saysWell-planned plant-based diets are reliably linked to better cholesterol and lower cardiovascular risk, but the specific claims about energy, strength and skin are personal impressions rather than tested outcomes.

Verdict: The heart numbers hold up better than the mirror does.

Chris Paul said“Paul says switching to a plant-based diet started as a performance experiment and became permanent because of how his body felt and recovered.”

The science saysPlant-based eating patterns are consistently associated with lower cardiovascular risk in cohort studies, but the evidence that they improve athletic performance or recovery is thin and mostly neutral.

Verdict: Good bet for the heart, unproven as a performance edge.

Eric Topol said“After decades of prescribing mostly aerobic exercise, he says resistance training is the piece older adults should not skip, and he took it up himself in his seventies.”

The science saysStrong and consistent: muscle-strengthening activity is linked to lower all-cause mortality in pooled cohorts, and resistance training reliably improves strength and physical function in older adults in randomized trials.

Verdict: One of the few longevity habits where the trial data and the cohort data point the same way.
