Hey friends,

Most longevity conversations focus on labs, supplements, and biomarkers. This week’s guest, Roderick Lambert, goes deliberately upstream of all of that.

After 15 years of struggling with obesity and a doctor warning him at 35 that he could have a heart attack within five years, Roderick overhauled his life, lost 24kg in seven months, and never looked back. Today he coaches people aged 40–60 on the root causes of metabolic decline and accelerated aging.

The calories in, calories out model isn’t just bad advice. It’s physically inaccurate.

You’ll discover:

* Why mitochondrial dysfunction is the root cause of most chronic diseases

* How fat produces up to 6x more usable energy than glucose

* Why the 40–60 window is your last real chance to turn back the clock

* The role of light, circadian biology, and coherence in cellular health

* Why “you can’t get well in the environment you got sick in”

* How to build habits that stick, without willpower

Cheers, Nina
