I have decided to do my report on what I feel is the most horrible disease, obesity. One day while watching TV. I came across this talk show, which featured over weight people who are at great risk of dying due to their complications from obesity. Writing about obesity, has given me an opportunity, to learn more about this killer disease of 21st century.
The clinical definition of obesity is excessive body fat, defined as weight at least 20% more than optimum. It is usually caused by sedentary habits and a diet high in fat, alcohol, or total calories. Calories consumed but not used are stored as fat. Rare causes include glandular defects and excess steroid. This is usually expressed in terms of body mass index (BMI), which is derived by dividing one’s weight by the square of one’s height (Allison & Saunders, 2000).
· Obesity tends to run in families, suggesting a genetic link. Yet families also share diet and lifestyle habits that may also contribute to obesity. Separating these from purely genetic factors is not easy.
nvironment also strongly influences obesity. This includes lifestyle behaviour such as what a person eats and his or her level of physical activity.
