Help Me Lose Fat Please help?

This might not be the most righteous forum for this query, but since weight loss is a national epidemic, I was thinking that there is going to perhaps be some men or girls here, who have been on any weight loss plans at all. If you have some knowledge whatsoever please share.I am especially confused on what diet item to order, as there are so several alternatives in the market. The most recent hypes on Oprah like hoodia gordonii or green tea don't make this subject any more straightforward. I really don't have an idea where to start, should I get an exact weight loss program, routine of exercises...All I have come to understand is that an alteration is needed. And this change needs to take place now.
