However, Glaser (2007) clearly defined obesity as unhealthy condition, not a disease. According to him, when more extra calories are stored in fat cells overtime, especially kids who have taken in more calories become bigger. Therefore those who ate too much calories by with few or no active physical activities have great chance to gain weight or become obese. However, he argued that it cannot be denied that sometimes obesity runs in families. With this, Glaser exactly believed that there are some other factors causing the disease aside from the level of calorie intake.
However, what seems to be hurting about obesity is that it stands as the reason for other complications such as other diseases and medical conditions. Smith (1999, p. 1 - 16) was able to discuss the contemporary and undesirable effects of obesity. He discussed the association between obesity and overall mortality, obesity and its effects on the heart and blood vessels, obesity and its effects on the respiratory system, obesity and its association with high blood pressure, obesity and its effect on blood lipids, obesity and its association with type II diabetes, psychosocial consequences of obesity, obesity and its effects on other body systems and the cost of diseases associated with obesity.
The good thing about obesity is that there is an available measure for it and that it is based on standard making its detection so easy and simple. The levels of adiposity going over a prespecified cut-off are the criteria for overweight or obesity (Cole and Cachera, 2002, p. 15). They explained that adults with 25 kg/m2 body mass index (BMI) are overweight and those who have 30 kg/m2 body mass index are considered obese.
They pointed out that applying these cut-offs to children would screen them at different ages and will be complicated further by the differences of maturation. Body Mass Index (BMI) in simple terms is the simple measure of obesity by comparing a person’s weight with his or her weight (Hicks, 2008, p. 14-21). The use of BMI to classify obesity can be considered to provide useful measure of obesity according to the World Health Organization (2000, p. 9). According to Hicks, people as they grow older gain weight because their bodies tend to slow down in converting food into energy.
He also added that a child who is obese has greater chance of becoming obese adolescent and adolescents who are obese are most likely to become obese adults. What causes obesity? Too much attention has been given to obesity today due to the reason as mentioned earlier, that excess body weight has been viewed to bring serious public health challenges and overweight is responsible for the widespread occurrence of large proportion of disease in the WHO European region (WHO Europe, 2007, p.
