Most people assume aging means slowing down — but longevity expert Dr. Peter Attia says that doesn’t have to be true. According to the Stanford-trained physician, many Americans “fall off a cliff” around age 75 — a point where health, strength, and independence decline sharply. But, he says, with the right habits, that plunge can be prevented — or even reversed.

“In your seventies, most people see a huge drop-off in their physical and mental health,” Attia told 60 Minutes. “At 75, both men and women fall off a cliff.”

Yet his message isn’t one of inevitability — it’s one of empowerment. With deliberate lifestyle changes, Attia says it’s possible to extend not just lifespan, but what doctors now call healthspan — the number of years lived free from disease and disability.

Dr. Douglas Vaughan, director of Northwestern University’s Potocsnak Longevity Institute, explained that the key lies in lifestyle. “Stopping smoking, drinking less, maintaining a healthy weight, exercising, avoiding processed foods, and prioritizing sleep all extend healthspan,” he told Fox News Digital.

Attia shared five major strategies he uses with his patients to help them stay strong and independent deep into old age.

1. Train Like Life Is a Sport

Attia says the single best predictor of longevity is fitness — specifically, a high VO₂ max (a measure of cardiovascular capacity). “Your VO₂ max predicts your risk of death from any cause, even more than blood pressure, cholesterol, or smoking status,” he said.

He personally logs about 10 hours of exercise per week, mixing fat-burning cardio, high-intensity intervals, and strength training. Maintaining muscle, mobility, and endurance, he says, should be treated like a lifelong sport.

2. Eat More Protein Than You Think You Need

Current nutritional guidelines, Attia argues, undershoot the amount of protein needed for healthy aging. He recommends doubling the standard protein intake to help preserve muscle mass, support immunity, and reduce disease risk as the body ages.

3. Track the Right Health Metrics

Attia emphasizes testing that goes beyond traditional bloodwork. He uses DEXA scans to monitor bone density and body composition, along with fitness metrics like VO₂ max to track how efficiently the body uses oxygen during exertion.

4. Don’t Neglect Emotional and Mental Health

Physical health alone isn’t enough. “By working hard on our physical health, we can reduce the rate of decline,” Attia said. “But if we’re deliberate and active on our emotional health, it can actually improve.” He encourages practices that nurture connection, gratitude, and purpose — qualities that have been shown to lengthen lifespan.

5. Optimize the “Marginal Decade”

Finally, Attia says everyone should think ahead to what he calls the marginal decade — the final 10 years of life. “The marginal decade’s not going anywhere,” he said. “We will all have a final decade. The question is — what kind of shape do you want to be in when it arrives?”
Attia’s message is clear: aging is inevitable, but decline doesn’t have to be. The key isn’t just adding years to life — it’s adding life to those years.
