Being fat causes problems for everyone  Obesity causes huge medical costs - in the USA alone, around 150 billion dollars [6]. This is because obesity is linked to Type 2 Diabetes, cancer, heart problems, strokes, asthma and other medical problems.  Many of these diseases need lifelong treatment following expensive diagnosis, and often emergency treatment.  This not only has human effects, but causes problems for the economy due to being less productive at work and taking lots of medical leave. Due to obesity’s costs (financial and otherwise) to society, it can’t be considered as something that only affects individuals any more [7].
