Diet pill that works

My neighbor is having so many problems when it comes to dieting.  She has spent thousands of dollars over the years on diet pills and diet plans. None of them seems to work but on the other hand she never does anything to exercise. She's quite a fun person so I expressed to her that it would be fun to pick up a dance aerobic video so we could do it together. Now if we could just find a diet pill that works it will help out with her big problem.
