Daily vitality: the felt sense of having gas in the tank.

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.

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.
