Causes of obesity
Obesity is an increasing, global problem with social, cultural and psychological causes. The human body has a mechanism to balance energy intake (food) and energy expenditure (activity). In the current age, day-to-day energy expenditure can be low because of the availability of mechanized transport and labour-saving devices in the home and at work. Simultaneously, irregular eating patterns and consumption of high- energy foodstuff can lead to failure of the inbuilt energy balancing mechanism. Some individuals may have a genetic predisposition to obesity and a low metabolic rate that makes them particularly vulnerable. Very few people have a specific hormonal problem that is responsible for obesity.
