Some people unfortunately fall for the fad that they can lose weight fast. While this may be possible theoretically, it is not the best thing to do. The problem is that people who try to go for rapid weight loss end up causing damage to their bodies because they may be tempted to excessively use diet pills, without being aware of the dangers of diet pills. Even those who go off food completely are not aware of how much harm they may end up causing to their bodies in the long run.
