diet pills

Do you suppose scientists will ever create a true diet pill? I mean, right now we have pills like phentermine which work okay, but take time. I wonder if they will ever create a pill that works fast. I know that there is certainly a demand for a pill or some other quick fix way to become skinny, but I honestly doubt they will ever succeed at creating that. I just think there are a lot of things with the human body that we may want, but I just don't think we can control everything.
