Stanford-trained physician Peter Attia, MD, wants Americans to think differently about aging. In an interview with CBS News’ 60 Minutes, he said the last 10 years of life—what he calls the “marginal decade”—are often marked by rapid declines in strength and independence. More than 90% of U.S. seniors live with at least one chronic disease, according to the Centers for Disease Control and Prevention.
Attia argues that waiting for disease to develop has failed too many people. His “Medicine 3.0” approach shifts focus to prevention decades earlier, including strategies meant to reduce risk for heart disease, cancer, diabetes, and dementia. “My goal is to make the marginal decade as enjoyable as possible,” Attia told CBS News.
The Exercise and Nutrition Habits That Predict How Long You’ll Stay Strong
Attia treats fewer than 75 patients, many of them billionaires paying six-figure annual fees, as reported by CBSNews. Their program begins with advanced physical testing in Austin, Texas, including assessments of muscle mass, mobility, and cardiovascular fitness. He explained to CBSNews that VO2 max, the body’s ability to use oxygen during intense exercise, is one of the strongest predictors of lifespan.
A similar style of longevity performance testing is now being offered to the public at Biograph’s New York City and San Fransisco clinics, according to the company.
Attia recommends about 10 hours of weekly exercise across strength training, steady-state cardio, and high-intensity intervals to help maintain muscle and slow age-related decline. He also advises patients to prioritize protein intake to prevent frailty. Tools like DEXA scans are used to identify early risks such as low bone density or harmful visceral fat.
Mental Health and Social Connection Matter Too
Attia told CBS News that longevity isn’t limited to physical training. After decades of personal mental health struggles, he now emphasizes that counseling, stress management, and strong social connection play key roles in living longer. Research cited by CBS links supportive relationships with improved long-term health outcomes.
Some experts question whether costly MRI screenings and experimental therapies improve lifespan. Attia maintains that most of his approach—exercise, nutrition, sleep, and connection—remains accessible without a concierge medical practice. You have to take a much longer arc on prevention, he told CBS News.
