Are your midlife clients experiencing unexplained weight gain, mood changes, brain fog, sleep disruption, or rising concerns about longer-term cardiovascular and cognitive health?

This one day course examines a whole-body, functional approach to the menopause transition equipping you with the clinical knowledge, testing tools, and evidence-based strategies to assess and address its multi-system impact in practice.

This one-day CPD course takes a functional, systems-based approach to menopause, beginning with the hormonal transition and the far-reaching consequences of hormone decline across the body and brain. It then moves through four key clinical domains:

•Metabolic health: insulin resistance, weight, sarcopenia, and mitochondrial function

•Cardiometabolic health: lipid changes, ApoB, blood pressure, endothelial function, and cardiovascular risk

•Brain health: mood, cognition, anxiety, and oestrogen-neurotransmitter interactions

•Gut health: the estrobolome, microbiome shifts, motility changes and systemic impacts

Join us for this live online CPD course with Christine Bailey in the Kitchen RNutr, BANT, AFCMP who will be answering questions throughout the day!

What if fermentation was more than a food trend?

In this fascinating conversation, Ukrainian chef and author Olia Hercules reflects on food, identity and resilience, sharing memories of Ukraine and discussing how fermentation became her “act of resistance” following the war in Ukraine. She explores the therapeutic power of cooking, the connection between neurodiversity and food, and why preserving recipes and traditions matters in times of crisis.

A moving and deeply human piece about nourishment, memory and survival.
