Eating Behaviour

Designer Tomás Louro worked with researcher Luca Savorelli to produce this poster that visualises a theoretical model to assess the ideal body weight as seen by society from a welfare and health perspective.

Luca did his PhD at the Department of Economics and he describes the motivation behind his research.  He says ‘the increasing concern of the policy maker about eating behaviour has focused on the spread of obesity and on the evidence of people dieting despite being underweight. As the latter behaviour is often attributed to the social pressure to be thin, some governments have already taken actions to ban ultra-thin ideals and models.This research explores the extent to which the increasing role model size becomes desirable and aims to propose a theoretical frameworks to assess whether increasing the ideal body weight is socially desirable both from a welfare and health point of view.’


This is a theoretical piece of research.

Main Findings…

If being overweight is the average condition and the ideal body weight means being thin, increasing the latter may increase welfare by reducing social pressure. By contrast, health may be impaired since people are induced to depart even further from their healthy weight. Given that in the US and in Europe people are on average overweight, we conclude that these policies, even if welfare improving, may exacerbate the obesity epidemic.
