The Science of Women’s Energy, Hormones, and Feeling Like Yourself Again - with Dr Stacy Sims

If you have ever wondered:

💭 “Why do I feel exhausted, foggy, or flat even though I am doing all the ‘right’ things?”
💭 “Why does what used to work for my body suddenly feel wrong?”
💭 “How do I support my energy, hormones, and health without fighting my body?”

this episode is for you.

In this deeply informative and empowering conversation, Tess and Layne welcome world leading exercise physiologist and nutritional scientist Dr Stacy Sims into the studio to unpack the science of women’s bodies, hormones, and energy across every stage of life.

Layne opens up about the moment she realised she was losing herself. Fatigue, brain fog, mood changes, and the quiet fear that something was wrong. Tess shares what it was like watching her best friend struggle and not knowing how to help, until science finally provided clarity and relief. Together, they trace the path that led Layne to Dr Sims, and the practical tools that helped her reclaim vitality, presence, and confidence in her body again.

Dr Sims explains why women are not small men, how decades of research failed to include female physiology, and why so many common wellness trends actively work against women’s hormonal health. From intermittent fasting and under fuelling, to training styles that drain instead of build, she breaks down what actually supports female energy, cognition, sleep, and long term health.

This episode is not about perfection or fear. It is about education, empowerment, and understanding what to look for so you can respond early, not panic late. Whether you are in your twenties, approaching perimenopause, or navigating menopause, this conversation reframes what is possible when science finally reflects women.

You will hear about:

The science behind female hormones and why women respond differently to food, stress, and training
Why intermittent fasting and under eating can disrupt sleep, mood, and metabolism in women
How protein, creatine, adaptogens, and strength training support brain and body energy
The difference between sprint interval training and high intensity training for fat loss and health
How heat therapy, sleep, and stress regulation improve mood, cognition, and resilience
What partners can do to better support women through perimenopause and menopause
Why knowledge, not fear, is the key to navigating this stage of life with confidence.
