Nerys is a human nutrition scientist with a strong interest in clinical trial methodology and evidence-based medicine. Nerys has worked at the University of Manchester and the New York Obesity Research Center at Columbia University in New York City. She is currently Associate Professor in diet and obesity in the Health Behaviours Team at the University of Oxford. Her main interests are how dietary manipulations impact weight management and the regulation of energy intake. She leads a programme exploring the effect of dietary interventions and weight management before, during and after pregnancy can influence health of mothers and their children.

Nerys explains why maintaining a healthy weight is so important. Obesity is a major global health concern, increasing the risk of many chronic diseases and reducing quality of life. Yet today, we are constantly bombarded by clever marketing of unhealthy, ultra-processed foods. Perhaps it’s time to focus on eating for quality rather than quantity. Nerys also explores how a healthy weight supports fertility, pregnancy, and the health of our children, as well as the challenges of weight gain as we age — for both men and women. We discuss the many approaches people take to lose weight — from diet plans and exercise to weight-loss medications — and emphasise the importance of finding a sustainable nutrition plan that truly works for you.
