Obesity is a becoming a major health problem in Europe and it's driven to some extent by rising junk food consumption. Junk food has negative externalities and recent research finds that its demand is fairly elastic. If it is so natural to tax cigarettes, why not tax junk food as well?

Obesity at the individual level is a medical problem, but the rapid rise in global obesity is a policy problem. Research on US data shows that the obesity is inversely related to a variety of measures of social and economic advantage. One important factor is years of maternal education, but much of the link between socioeconomic factors and obesity remains unexplained.

The industrialised world is getting fatter with the US showing the way. CEPR DP6191 tracks the data of nearly 6,000 people over six years and finds a strong correlation between obeseity and living in an urban-sprawl area; however it finds that this comes from the fact that people who are more likely to be obese are more likely to move to sprawling neighbourhoods.
