Okay, hello and welcome to another episode of Sigma Nutrition Radio. I am your host,

Danny Lennon, and this is episode 404 of the podcast.

And today I am truly honored to be joined by Professor Marion Hetherington.

Professor Heatherington is Professor of Biosychology at the University of Leeds, where her

research is focused on the psychology of appetite across the lifespan. And she has previously been places

like John Hopkins, the NIH, University of Dundee, University of Liverpool, and Glasgow-Caladonian

University before she took up her role in Leeds, where she works within the Human Appetite

Research Unit. And there are so many aspects of her important and very influential work

that I'm really excited to discuss with her today. So on that note, Professor Hetherington,

welcome to the podcast. Thanks for having me. Like I said, I'm very excited to dive into a lot of

these topics. And I think something that might set the stage for people early on is when we think about

this psycho-biological approach to human appetite, you've written really excellently

in some of your work about the mistake we might make if we were to consider appetite solely on the basis of

physiology or psychology, particularly when we think around what drives food intake, and that

they're inextricably linked. I was wondering, could you just frame that for people of what is

the most accurate way we can think of that overlap between physiology and psychology

when it comes to appetite? Well, as a behavioral scientist, I'm very interested in human behavior,

but you just can't get away from the fact that human behavior is driven by really strong

physiological needs.

However, food intake in our society, as everyone is aware, is very much shaped by our culture,

by our cuisine, by our environment, and to a great extent, what we eat is part of our identity. So when we think about psychobiology

of appetite, we're thinking about the behaviours that we express and we think about what drives
