Obesity has increased greatly in recent years in the UK. Some commentators have attributed this to people becoming greedier in a consumer society; however, obese people should not be blamed for their condition when it is the food environment in Europe that has changed. Obesity results from a combination of genetic factors and a fast-food culture that provides an easy supply of cheap, sugary and processed snacks and meals that are high in calories. This is compounded by the shift to more sedentary lifestyles both at work and in leisure time, which has led to a lack of exercise.
