What is Obesity?
Overweight and obesity are defined as abnormal or excessive fat accumulation in the body that presents a risk to health. Obesity will have a negative effect on health, leading to reduced life expectancy and/or increased health problems. According to WHO, Obesity is one of the most serious public health problems of the 21st century.
Obesity isn’t just a cosmetic concern. It increases risk of diseases and health problems such as heart disease, diabetes and high blood pressure.In 2013, the American Medical Association classified obesity as a disease.
Obesity means having too much body fat. It is different from being overweight, which means weighing too much. The weight may come from muscle, bone, fat, and/or body water. Both terms mean that a person’s weight is greater than what’s considered healthy for his or her height.
Obesity occurs over time when one eats more calories than use. The balance between calories-in and calories-out differs for each person. Factors that might affect our weight include our genetic makeup, overeating, eating high-fat foods, and not being physically active.
Is Obesity a new disease of the new world?
Hippocrates wrote that “Corpulence is not only a disease itself, but the harbinger of others”. As early as 6th century BC, the pioneer Indian surgeon Sushruta related obesity to diabetes and heart disorders. He recommended physical work to help cure it and its side effects. Thus Obesity is prevalent since the ancient times, but has reached epidemic proportions globally in the 21st century.
