20 - Hormones and metabolism: Unlocking the science with Professor Franck Mauvais-Jarvis

“I don’t understand why we’re not shouting this from the rooftops, a simple medicine, a natural hormone, that can reduce the risk of both diabetes and breast cancer. That’s incredibly important, isn’t it?”

This week, Dr Louise Newson is joined by Franck Mauvais-Jarvis, Professor of Medicine at Tulane University and an endocrinologist specialising in metabolism.

In this episode, they dive deep into the science behind oestradiol’s crucial role in maintaining a healthy metabolism, reducing inflammation throughout the body, and supporting memory and cognition.

Professor Mauvais-Jarvis explains how improving mitochondrial function, often referred to as the “powerhouse of the cell,” boosts metabolism and helps prevent metabolic diseases such as diabetes. He also highlights the vital, often overlooked role of testosterone in women’s health.

Together they address common misconceptions stemming from the 2002 Women’s Health Initiative (WHI) study and set the record straight on the benefits of body-identical hormones.

Be sure to check out Professor Franck Mauvais-Jarvis’s book, Principles of Precision Hormone Therapy: Healthy Aging and Prevention of Chronic Disease , which presents cutting-edge scientific data and insights from leading experts, including Dr Louise Newson, on the vital role of hormone optimisation in healthy aging.
