This week Brett interviews Stephan Guyenet, author of the book The Hungry Brain about the science of over eating. With a background in biochemistry and neuroscience Stephan brings a great understanding of the research to the table and is able to explain the concepts in a very easy to understand and honest way. Stephan shares what he has learnt from examining non-industrialised societies, not only  and the way they lived and ate but also the way their brains were wired and why to come up with a very comprehensive understanding of why our brains react the way they do in our modern society. So if you want to understand why your brain is subconsciously telling your body to do the wrong thing even when you are consciously trying to tell your body to do the right thing then this is the episode for you!
