Obesity and its Causes
On the surface, the cause of obesity seems simple: if a person consumes more calories than he can burn as energy through physical activity, then you'll gain weight. But like many things, the simple explanation is often incomplete. The risk factors that contribute to obesity can be a complex combination of genetics, socioeconomic factors, metabolic factors and lifestyle choices, among other things. Some endocrine disorders, diseases and medications can also cause weight to increase. There are many deductions of obesity in an individual alike.The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories expended. An increased intake of energy-dense foods that are high in fat; and an increase in physical inactivity due to the increasingly sedentary nature of many forms of work, changing modes of transportation, and increasing urbanization. Changes in dietary and physical activity patterns are often the result of environmental and societal changes associated with development and lack of supportive policies in sectors such as health, agriculture, transport, urban planning, environment, food processing, distribution, marketing, and education.
