Is Obesity a Public Health Problem?

It is often claimed that there is an obesity epidemic in affluent countries, and that obesity is one of the most serious public health problems in the developed world. I will argue that obesity is not an ‘epidemic’ in any useful sense of the word, and that classifying it as a public health problem requires us to make fairly controversial moral and empirical assumptions. While epidemiological evidence suggests that the prevalence of obesity is on the rise and can lead to serious health problems ranging from diabetes to cardiovascular disease, this does not by itself show that obesity is a public health problem.
