We must also look at the logic behind dieting. Oftentimes, people desperately want to lose weight but cannot because they consume an excess amount of calories than their bodies need. A lot of times, this is caused by emotional eating or overeating. If we as human beings ate only when we were hungry and stopped when we were full, the diet industry would not nearly be as huge as it is today. But, it is not that simple.
People eat when they are tired, lonely, and sad or feeling isolated.
Sometimes people eat when they are joyous or really happy. In either case, appetite suppressants would not be helpful since people are not eating to satisfy hunger. Human beings are the only species in the universe that have such a problem with obesity. This is probably due to our over abundance of food sources and our tendency to link other emotions with feelings of hunger and food. Every other species of animal eats for survival and no other reason.
