Social and psycological problems:

Obese people are always being discriminated by the society and being less welcome as compare to slim and attractive ladies. In traditional Chinese population there is mis-conception and believed that obesity is simply as a behavioral problem, which is voluntary, and usually associated with some degree of moral deficiency, from want of self-control to unrestrained gluttony. This attitude posted additional stress to obese individual and may lead to depression, low self-esteem with social avoidance, and severely affect their social and interpersonal relation.
