The way you take care of yourself beyond what you The way you take care of yourself beyond what you eat has incredible power to positively influence your epigenetics (ie gene expression) and therefore your pace of biological aging (and longevity!)

Here’s a quick summary of the lifestyle pillars that will not only help you feel your best but also support your epigenome and healthspan:

✅ Sleep is a fundamental component of health and a powerful - and fast - influencer of the epigenome.
✅ Movement acts like yet another EpiNutrient by turning bad genes off and turning on genes we want activated, and giving you the DNA methylation patterns of a younger person.
✅ A consistent relaxation practice (meditation, breathing exercises, yoga, qigong, tai chi mindfulness and more) may have a profound effect not only on your biological age, but also on the associated, chronic diseases of aging.
✅ Connection: When you are relating to someone else, whether that’s a friend, a partner, a child, or a pet, you are reducing stress (and poorly managed, chronic stress drives biological aging forward like gasoline poured on fire).

When you combine high-quality nutrition with the above lifestyle pillars - like we do in the Younger You program - you function at your best, you feel amazing and best of all, you get to slow down your pace of aging.

What lifestyle practices do you do regularly? Which ones do you struggle with? Comment below!

Pomegranates, walnuts and Urolithin A - what’s t Pomegranates, walnuts and Urolithin A - what’s the connection?

Our gut bugs can transform compounds found in foods, such as pomegranates and walnuts, into Urolithin A - a compound with the ability to stimulate mitophagy and mitochondrial renewal, leading to improved muscle strength and endurance, immune health, cognitive function, and skin health at the cellular level. That’s remarkable!

On the New Frontiers podcast, I chat with Dr. Chris Rinsch, researcher, inventor and co-founder of @timelinenutrition, about the incredible scientific journey of Urolithin A’s discovery and subsequent unfolding of its many benefits, as confirmed by multiple clinical studies.

The single biggest driver of chronic disease isn’t obesity or chronological age, it’s biological age, which can be slowed down at the epigenetic level with targeted interventions.

No magic potions required. Just tweaking your normal lifestyle: food, sleep, exercise, and relaxation, but nothing beyond what most folks consider to be basic self-care.

That is the core of our research and the promise of the Younger You method - a very doable (and highly targeted) diet and lifestyle program. You can find it in the Younger You book or experience one of my Younger You group programs.
