Diet pills that really work for women?

I have been having a lot of trouble loosing weight lately.
I have tried slim fast, and that really didn't even help :(
Has anyone used any diet pills that have really worked
with low side effects? Also, I want something that gives
me energy, not just weight loss, and maybe something that
kick starts a work out. I have read a lot of reviews about
pills and that makes every one of them seem great.

take decision from expert nutritionist and follow what they recommend.
