Every 12 years, our skeletons undergo a complete transformation.

Prof. Tim Spector and Prof. Cyrus Cooper discuss how to avoid Osteoporosis, a condition where bones become fragile, significantly increases the risk of fractures from minor incidents, often without any noticeable symptoms. Worldwide, it affects one in three women and one in five men over fifty, leading to pain, potential disability and loss of independence.

In today’s episode, Jonathan, Tim and Cyrus ask the question: How can understanding osteoporosis and implementing targeted lifestyle changes enhance bone health and reduce the risk of fractures?

Cyrus Cooper is a Professor of Rheumatology at the University of Southampton, where he is also the Director of the MRC Lifecourse Epidemiology Unit and Vice-Dean of Medicine. In addition, he’s a Professor of Musculoskeletal Science at the Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences at the University of Oxford.

Tim Spector is one of the world’s top 100 most-cited scientists, a professor of epidemiology, and scientific Co-Founder at ZOE. Tim trained originally in rheumatology and epidemiology.

Our bodies naturally follow a roughly 24-hour cycle, called our circadian rhythm. And every cell has a rhythm.

As we get older, we tend to lose muscle, making us more prone to falls and less able to live independently. Though we can't stop aging, staying active helps keep our muscles strong and our bodies healthy for longer.

Prof. Karyn Esser is a specialist in how the body's natural rhythms affect muscles. Today, she guides us through the latest research and shows that it's always possible to harness the power of your muscles to enhance your quality of life. She is a professor in the Department of Physiology and Aging at the University of Florida, where she’s also the co-director of the University of Florida Older Americans Independence Center.

In today's episode of ZOE Science & Nutrition, Jonathan and Karyn explore the body's internal clocks and ask: why do our muscles have their own schedule, and is there an ideal time of day to exercise?
