Poor and fat

Studies about the predictors of obesity in the UK have shown that the poorest are most likely to be obese. For example, one University of Glasgow study found that residents of an impoverished Glasgow neighbourhood were more than twice as likely to be obese compared with residents of an affluent neighbourhood only miles away. This pattern holds among children, teenagers and adults; men and women; and across ethnic groups.

In places such as Ethiopia (a low-income country that has had several serious famines in recent decades), the cheapest foods are the least calorie-dense; therefore, the poor systematically lack access to energy-rich foods, and have a higher likelihood of suffering from undernutrition and starvation. By contrast, in a city such as Glasgow, the cheapest foods are the most calorie-dense – kebabs, chips, crisps, pies and puddings, fizzy drinks etc – so the poor there are more at risk from obesity.

Deprived areas in cities , termed "food deserts" in the academic literature about obesity, fundamentally limit the food choices that poor people can make, thereby promoting unhealthy lifestyles, and ultimately, obesity.A basket of healthy food would cost more in a poor part of east London, for example, than it would in somewhere like Fulham.

Another issue is what is termed "food insecurity", or lack of regular, dependable access to food. This can also promote obesity. Imagine that you didn't know where your next meal would come from, and you had a large meal in front of you at the time: what would you do? I would eat the whole thing (probably more than my fill), so that if, in fact, I didn't get a meal later, I would have eaten enough for the day. Now, what if the next meal did come (again, in the same setting of insecurity about where the next meal would come from)? A cycle of insecurity-based overconsumption can set in, ultimately leading to obesity.

A study in the International Journal of Obesity upon following over 11,000 Britons for 33 years, showed that low parental social class at age seven was a significant predictor of obesity at age 33. If a factor as intractable as parental social class can influence obesity risk 26 years later, it is hardly helpful to blame every obese individual for his or her condition.
