Your food is secretly controlling 12 critical hormones | Dr Helen O'Neill

Описание: Hormones control almost every system in your body. They are like an orchestra playing, so when one instrument is a little off-key, it affects the whole system. If you feel tired, anxious, or are gaining weight, your hormones may be involved.

In this episode, leading reproductive expert Dr Helen O’Neill explains how hormone health affects fertility, metabolism, and mental health for both men and women.

The core question is simple: if hormones run your body, how much influence do you have over them?

Alongside ZOE’s head nutritionist, Dr Federica Amati, Helen explores the links between hormones and fatigue, anxiety, weight gain, fertility, and metabolic health. The episode covers thyroid health, chronic pain, sperm health, and why gut hormones play a central role in appetite and weight regulation. We also examine why some female-specific conditions remain misunderstood or undiagnosed, and how better data may help change that.

Most importantly, this episode focuses on what you can do to take back control. With emerging science suggesting that diet plays a key role in hormone regulation, you’ll hear how fibre, plant diversity, healthy fats, and key micronutrients support gut hormone production and fertility. You’ll also learn why changes made over three months may meaningfully influence fertility, and why conception is always a shared responsibility.
