Another obstacle people face when trying to change their bad health habits is the pleasure they get from these unhealthy practices. For example, junk food and sweets are fun to eat. A person may crave her favorite foods and derive great pleasure from eating them. Many unhealthy behaviors are automatic, such as planting oneself in front of the television for several hours each night. Any habit that is pleasurable is difficult to break, and in our society eating junk food and watching hours of TV are two of the strongest.
