It is well known that obesity is a severe, self-inflicted health problem of epidemic proportions in the developed world. It is without doubt that there are medical risks associated with obesity - hypertension, heart disease, type 2 diabetes, cancers and so on. In addition, the obese are more likely to suffer low esteem, social disadvantage and reduced libido. Denmark has imposed taxes on some products - butter, crisps and mince - and British Prime Minister David Cameron, at the Conservative Party Annual Conference in 2011, raised the possibility of a similar tax in the United Kingdom.
