A fact-check

3/10Science Score

Tom Brady said

Celebrity health advice, checked against the science.

Arnold SchwarzeneggerAge 78

9/10Science Score

Arnold Schwarzenegger said“Eat enough protein and keep lifting, and you hold on to your muscle as you age.”

The science saysStrongly supported. Protein plus resistance training is one of the best-proven ways to protect aging muscle.

Why this scoreBacked by multiple clinical trials.

Verdict: Real, and worth copying.

Jane FondaAge 88

6/10Science Score

Jane Fonda said“Stay strong and keep moving as you get older, or you end up dependent on everyone else.”

The science saysWell supported. Large population studies tie lifelong activity to a longer, more independent life.

Why this scoreDecades of population studies agree.

Verdict: Forty years on, the data still agrees with Jane.

Chris HemsworthAge 42

8/10Science Score

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.

Why this scoreBacked by large population studies.

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

Jennifer AnistonAge 57

6/10Science Score

Jennifer Aniston said“A daily scoop of collagen peptides keeps your skin, hair, and joints younger.”

The science saysPartly true. Trials show collagen can help skin, but the strongest results come from industry-funded studies, and the hair and joint case is thin.

Why this scoreTrials exist, but sellers funded them.

Verdict: It works on skin. It also works for the company she runs.

Halle BerryAge 59

6/10Science Score

Halle Berry said“The ketogenic diet reversed my health problems and slows down my aging.”

The science saysHalf right. Keto can lower blood sugar in the short term, but 'reversed it' is a louder claim than the trials will sign off on.

Why this scoreTrials show short-term help only.

Verdict: Keto earns a B. 'Reversed it' is grading on a curve.

Gwyneth PaltrowAge 53

7/10Science Score

Gwyneth Paltrow said“A long daily intermittent fast, coffee then bone broth, keeps me well and detoxed.”

The science saysOverstated. Intermittent fasting works about as well as simply eating less, with no special detox or longevity magic.

Why this scoreTrials show it works like any diet.

Verdict: Skipping breakfast is a tool, not a detox spell.

Joe RoganAge 58

5/10Science Score

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.

Why this scorePopulation studies, not clinical trials.

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

Jennifer LopezAge 56

2/10Science Score

Jennifer Lopez said“I don't drink alcohol or caffeine, and that is why my skin doesn't age.”

The science saysMostly backwards. Skipping heavy alcohol may help your skin, but blaming coffee runs against the evidence, and she now sells a cocktail line.

Why this scoreThe evidence leans the other way.

Verdict: Skip the wine if you like. Keep the coffee.

David SinclairAge 56

3/10Science Score

David Sinclair said“Taking resveratrol every day helps slow down human aging.”

The science saysNot established in people. Resveratrol extended life in mice on a rich diet, but human trials and a failed drug program never showed the benefit.

Why this scoreProven in mice, not in people.

Verdict: Spectacular in a mouse, unproven in a professor.

Tom BradyAge 48

3/10Science Score

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.

Why this scoreNo solid evidence either way.

Verdict: Tomatoes are fine. Eat the tomatoes.

Bryan JohnsonAge 48

3/10Science Score

Bryan Johnson said“A strict protocol of food, sleep, exercise, and more than one hundred daily supplements can measurably slow how fast you age.”

The science saysNot established. The basics help, but slowing human aging with a large supplement stack is unproven, and a routine of one person cannot prove it works for anyone else.

Why this scoreToo early, and tested on one person.

Verdict: Measure all you want. The anti-aging headline is running ahead of the evidence.

How a fact-check works

A famous claim, checked against the evidence.

We take what a famous person says about living longer, then check it against the evidence. Each claim gets a Science Score for how well research backs it, and every profile ends in a plain verdict. The portraits are original icons of the habit, never real photographs.

How it works

Every claim gets a Science Score.

We never tell you a habit works because someone famous does it. The Science Score grades one thing only: how strongly published research supports the exact claim, from a single anecdote to multiple clinical trials.

Science Score, 0 to 10

One number, grading one thing: how strongly published research supports the exact claim, anchored to the standard evidence hierarchy. Nothing is invented to fit a story.

9 to 10 trials7 to 8 observational5 to 6 mixed3 to 4 preliminary

Sourced, every time

Every claim is tied to a real public statement, and every score is anchored to named, citable research. No invented quotes, no studies that do not exist.

What we will not do

We grade the claim and the evidence, never the person. No invented quotes, no claims of endorsement, no promises that any habit reverses aging or cures disease.
