Diet pills are the symptom of a larger problem in western culture; we expect instant results with out expending any energy. A good diet pill that is an end-all for our weight problems sounds reasonable because our culture teaches us that we deserve such things merely for showing up instead of practicing good eating habits and developing a good exercise program.
Although a diet pill can help some people shed weight quickly, there is no such thing as a good diet pill. This is because any effective diet pill is hard on your body and makes you lose weight in a way that makes you very likely to put that weight on again. For many people, diet pills can be the beginning of yo-yo dieting and long term health problems.
