How many ways to lose weight?

I am overwhelmed by the amount of products there are now a days to help us lose weight! I always want to know the best weight loss pills that work fast but come on! There are so many different brands and different kinds of products. When you turn the TV on, there are advertisements for so many different ways to lose weight! Then you go in to talk to an expert in a health store and you get the run around about 100 products and told that "it is up to you." Why can't there just be a couple products to choose from? wow!
