This film explores an interactionist approach to obesity:
Part 1: shows how cultural and environmental changes have altered our relationship with food and created an ‘obesogenic environment’.
But why isn’t everyone obese?
Part 2: filmed at the Dept. of Neuroscience at Cambridge University, Professor Giles Yeo explains the role of genetics in making some people more vulnerable to hunger and obesity than others.
Part 3: looks at new research from University College London that illustrates how the interaction of environmental change and genetic vulnerability is creating a growing cycle of obesity that some experts believe could make the current generation of children the first to die before their parents.
