Business Insider profile: Matt Kaeberlein’s 4 habits for healthier aging
On a February 7, 2026 Business Insider feature, Optispan CEO and longevity researcher Matt Kaeberlein describes how he reshaped his lifestyle after moving from academia to building Optispan in 2023—shifting his focus from “living longer” to maximizing quality of life over time.
He highlights four practical habits:
Cleaner nutrition: reducing ultra-processed foods, moderating red meat, and paying closer attention to added sugars and labels.
Less alcohol for better sleep and consistency: cutting back on drinking—especially at home—after seeing clear impacts on sleep quality.
Training with intent: prioritizing strength training several days per week, pairing it with lower-intensity “zone 2” cardio, and adding an outdoor stair-climbing challenge to build cardiovascular capacity.
Stronger social ties: being more deliberate about maintaining friendships and saying “yes” more often to connection and outings—especially as a midlife male risk factor for social isolation.
