What If Your Doctor Is Wrong About Aging?

Is your biological age older or younger than your birthday? In this episode, I break down the 12 hallmarks of aging, how epigenetic clocks measure how fast you’re actually aging, and how to slow biological aging naturally with habits you can start this week. Here’s what most of us were never told: two people born the same year can be a decade apart biologically, and that gap is not random. It’s driven by twelve identifiable processes, from chronic inflammation and cellular senescence to mitochondrial dysfunction and gut dysbiosis. The best part? Randomized trials show that everyday choices, like an anti-inflammatory diet, regular exercise, quality sleep, time-restricted eating, and stress management, can measurably slow the pace of aging, and in one eight-week trial, even reverse epigenetic age. We’ll also talk about the debate over whether aging is a disease, what DNA methylation tests like DunedinPACE actually tell you, and where longevity science is headed next. What you’ll learn: * The 12 hallmarks of aging and how each one shows up in your body * How epigenetic clocks and DNA methylation testing measure biological age * The clinical trials showing lifestyle changes can slow and even reverse biological aging * How fasting and time-restricted eating activate autophagy, your cells’ recycling system * Why chronic inflammation and gut health accelerate aging, and the foods that help * What to know before buying a biological age test Dr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-your-doctor-is-wrong-about Check out the Habit Healers Community: https://www.skool.com/habithealers/about This is a public episode.
