Stanley Ulijaszek is Professor of Human Ecology and Director of the Unit for Biocultural Variation and Obesity, University of Oxford. Obesity rates have increased dramatically worldwide. Given the magnitude of the problem in both developed and developing countries, it is of utmost importance that academic work focuses on the various dimensions of the pandemic. Despite strong work in public health, psychology, and anthropology, there remains a knowledge gap concerning social and cultural aspects of the emergence of obesity among many of the worlds’ populations. Ethical dimensions of both individual and population obesity will be examined in this presentation.
