High Performance Health

In this conversation, Kristen shares the habits she believes have made the biggest difference, from sleep-wake consistency and strength training to high-intensity intervals, low-intensity aerobic work, daylight exposure and finishing food earlier in the evening. She also explains what to prioritise when time is limited — and why women do not necessarily need huge amounts of exercise to create meaningful physiological adaptations.

KEY TAKEAWAYS

HRV Can Change — Kristen says her HRV more than doubled over roughly a decade, showing that autonomic resilience is modifiable.

Sleep Consistency Comes First — Keeping sleep and wake times stable is the biggest lever she prioritises.

Strength Training Is Foundational — Resistance training supports physical capacity and is one of her core recommendations.

You Still Need Cardio — Strength alone is not enough for optimal cardiovascular fitness, resting heart rate and HRV.

Short HIIT Can Be Enough — A few brief hard intervals each week can create meaningful adaptations, especially if you are starting from a low baseline.

Zone 2 Supports Recovery — Kristen views lower-intensity aerobic work as a recovery tool that builds the base for harder efforts.

Light and Meal Timing Matter — Daytime light exposure and stopping food two to three hours before bed can support sleep and recovery.

Gary Brecka and I get into intermittent fasting, estrogen dominance, belly bloat and anxiety in perimenopause, and how the right test can show you exactly what your body is missing.

Ever feel like you're doing everything right, yet your lower belly won't shift and your mind won't switch off at night? So many women tell me this, and Gary gave me answers I hadn't heard from any other guest. I share how I found out I carry the MTHFR variant, something no one mentioned to me when I was pregnant. Gary explains why fasting can backfire when your HbA1c is already low, why the pace of your gut may matter more than food sensitivity tests, and how anxiety and gut issues can share one root. It's not about trying harder. It's about getting the right data.

WHAT YOU WILL LEARN

- Why the band around your lower belly, flanks and lower back can be estrogen-driven water retention, not fat, and how it can clear in 10 to 21 days

- What happens when a narrow eating window reads as starvation, from a lower thyroid signal to a slower metabolism

- How a 24-hour urine DUTCH test shows the estrogen to progesterone ratio a single blood test can miss

- Why lying awake ruminating, brain fog until midday and gut issues can share one root, and why Gary looks at methylfolate first

In this video, I explain the three mistakes that stop women over 40 getting the benefits of creatine, from taking a dose designed for young men to quitting before your muscles have had time to fill up. I also share the research on creatine for muscle, strength, sleep, brain energy and bone health after menopause, plus exactly how much to take for your goal and the easiest way to make it a daily habit.

Prof. Tim Spector and I talk about gut health, mood, inflammation and fermented foods in perimenopause, and the three diet changes he recommends to start today.

Microbiome pioneer, ZOE co-founder and Good Mood Food author Prof. Tim Spector explains why midlife mood changes are not psychosomatic: shifting hormones alter your gut microbes, which changes the inflammation and metabolic signals reaching your brain through the vagus nerve. He shares why serotonin was never the real lever, why inflammation and stable metabolism are, and why people in ZOE’s studies report better mood and energy within two weeks of changing their diet.

His three changes: 30 plants a week, three fermented foods a day and an overnight gut rest. We also cover ultra-processed food, protein versus fiber, HRT and dementia risk.

WHAT YOU’LL LEARN

- How perimenopause changes your gut and your mood

- Why inflammation matters more than serotonin

- Which ultra-processed foods to cut first

- His three gut changes to start today

Can HRT actually help women in midlife build muscle and reduce visceral fat — or is lifestyle still doing most of the heavy lifting? In this conversation, Dr. Federica Amati explains what her research found, where HRT may be helpful, and why it should be seen as one tool rather than the main driver of body composition.

She also explains why building muscle, eating well, moving regularly and protecting sleep before menopause can create a valuable buffer for later life. And for women already well into menopause, her message is equally important: meaningful change is still possible, but the fundamentals need to be built consistently into everyday life.

KEY TAKEAWAYS

HRT Is Not a Muscle-Building Shortcut — Dr. Amati says HRT alone will not increase muscle mass or reduce visceral fat.

HRT May Still Help Indirectly — Better symptom control and sleep can give women more energy to exercise and move regularly.

Lifestyle Remains the Biggest Driver — Exercise, nutrition, sleep and daily movement have a greater impact on muscle, bone and visceral fat.

Build Muscle Before Menopause If You Can — Going into menopause with more muscle and strong habits gives you a better starting point.

It Is Never Too Late — Women who are years into menopause can still transform their health.
