The modern generation consumes more food than the body requires, resulting in a greater amount of energy in the  body than it is able to burn and this leads to weight gain. One consequence of this overconsumption is that people lose the ability to realize that they have consumed enough food, and continue to eat more than required. The problem increases over the years, and as one get older, even smaller quantities of food can cause alarming weight increases. This weight gain can cause serious health problems and can also have an effect on one's self-confidence. Thus, obesity is now considered as a chronic disorder, and to treat and control this disorder, one needs to understand how the body deals with fat.
