Obesity

Obesity can often be defined as a condition in which excess body fat has accumulated to such an extent that health may be negatively affected. Obesity is assessed by BMI (Body mass index). Obesity is often associated with diseases such as certain types of cancer, asteoarthritis and cardiovascular diseases. Therefore as a result, obesity has been found to reduce life expectancy. The primary treatment for obesity is dieting and physical exercise.

Obesity has mostly increased because of the changes in portion sizes. Portion sizes have changed a great deal over the past 50 years. For example in 1950 a ‘Burger King’ burger was 2.8 oz, whereas in 2004 ‘Burger King’ burger was 4.3 oz. This therefore shows that the fat intake has increased making obesity rise. Another reason as to why obesity may have increased is that fast-foods etc have become cheaper and more accessible. There is no real surprise as to why fatty foods are so popular; some people argue it is due to the high advertisement of fatty foods. Finally another reason as to why obesity has increased is because lifestyles of many people have changed. Recent studies have shown that people who get 20 to 30 minutes of exercise most days are less likely to be obese. Your obesity risk is even lower if you combine an active lifestyle with a low-calorie diet. Therefore if you tend to sit at a desk or on a sofa most of your time, then your obesity risk is higher.
