High Performance Health

This episode highlights key points from our discussion on recognizing cognitive changes before Alzheimer’s disease reaches a later stage. We talk through early signs that can be easy to dismiss, including changes in memory, word-finding, emotional tolerance, recognizing faces, and navigating familiar places.

We also explore why a change from your own normal cognitive function matters and why earlier evaluation may create more opportunity to understand what is affecting the brain. The discussion also looks at the proposed shift from the brain’s normal “connection” processes toward a protective response when it perceives physiological stress or other insults.

She more than doubled her HRV in under a decade, and the behaviour that moved it most was not training, supplements or sleep duration, but going to bed and waking at the same time.

This week I sat down with Global Head of Human Performance at WHOOP and author of Aligned, Dr Kristen Holmes, to unpack why sleep-wake consistency is the foundation of a resilient nervous system in midlife.

WHAT YOU WILL LEARN

- Why is sleep-wake consistency a stronger predictor of mortality and disease than how long you sleep?

- How does the contrast between your day and your night affect the severity of menopause symptoms?

- What is the physiological sigh, and why did it outperform other anxiety-reducing techniques in the research?

- Can you really raise your HRV, and how much of it is genetic rather than modifiable?

- Why does eating late at night suppress both sleep quality and overnight recovery?

- Why do unresolved trauma and an outcome-driven identity keep your nervous system stuck in fight or flight?

Your heart is ageing faster than you think. It stiffens between 35 and 50, and shrinks between 50 and 65. For years this was written off as an unavoidable part of getting older. It isn't.The right type of exercise has been shown to reverse almost 20 years of cardiac ageing, and it takes far less time than you've been told.

If you're exercising more than ever but still feel exhausted, or pouring hours into cardio with nothing to show for it, this episode explains what's really happening in your heart, your mitochondria and your metabolism after 40, and the exact way to train smarter, not longer.

WHAT YOU'LL LEARN

- Why is my heart ageing faster after 40 and can I reverse it?

- Why do I feel tired but wired in perimenopause?

- What is the Norwegian 4x4 protocol and is it safe for women over 40?

- Do I really need 10,000 steps a day?

- How do squats after meals improve blood sugar and lower mortality risk?

Naturopathic doctor and author of The Cortisol Cure, Dr. Erin Kinney, explains why cortisol isn't the villain we think it is, but a "fix it" hormone you earn through rest and spend through everything else. She unpacks why decades of overspending leave midlife women with a depleted account, why that stubborn belly fat took years to build via insulin resistance, and why the instinct to push harder with more cardio and fewer calories only drains you further.

WHAT YOU'LL LEARN

- Why cortisol is your "fix it" hormone, not just a stress villain

- Why your midlife belly fat took years to build, and why you need cortisol to lose it

- How the body robs your sex hormones, then floods you with tired-but-wired adrenaline

- Why pushing harder with more cardio and fewer calories backfires

- How to tell your account is overdrawn, from morning fatigue to crashing after workouts

- Why building muscle, not cardio, is the top lever for flipping insulin resistance

- Which everyday activities are secretly a spend versus a deposit

- Which adaptogens and nutrients refill the account, and why carbs matter more than you think

The 3 Best Supplements for Mitochondria, Energy & Longevity in Menopause

Get my free Longevity Stack Masterclass and Supplement Guide for women to learn how to build a personalised supplement stack: https://academy.angelafosterperformance.com/free-longevity-stack-masterclass

In this episode, Angela explains how mitochondria produce energy, why mitochondrial function can become less efficient with age and hormonal change, and the three advanced supplements she personally uses as part of her longevity strategy: NAD precursors, urolithin A and MitoQ.

You’ll discover how each targets a different aspect of mitochondrial health — energy production, mitochondrial renewal and protection against oxidative stress — and why supplements work best when layered on top of the fundamentals of sleep, nutrition, exercise, cardiovascular fitness, stress management and, where appropriate, optimising hormones.

KEY TAKEAWAYS

Why Energy Can Change in Menopause — Declining oestrogen can influence mitochondrial biogenesis and the efficiency of cellular energy production.

NAD for Cellular Energy — NAD plays a critical role in helping mitochondria convert food and oxygen into ATP, the energy currency of your cells.

Urolithin A for Mitochondrial Renewal — Urolithin A supports mitophagy, the body’s natural process for clearing damaged mitochondria and making room for healthier ones.

MitoQ for Mitochondrial Protection — MitoQ is designed to reach the mitochondria directly and help protect them against oxidative stress generated during energy production.

TIMESTAMPS AND KEY TOPICS

01:38 — Three different ways to support mitochondrial health

02:50 — Supplement #1: NAD and cellular energy production

04:10 — Supplement #2: Urolithin A and mitophagy

06:22 — Supplement #3: MitoQ and oxidative stress

08:01 — Why supplements should come after the foundations

08:16 — Angela’s longevity supplement protocol and free masterclass
