Wondering about weight loss

In this day and age where so many people are so worried about their weight for health and yes even vanity reasons, there is no daught that there are a tone of weight loss products on the market. This makes it hard to tell which are the ones that are best for your particular situation. Sort of reminds me of all the different kinds of toothpaste that is out now. Have you noticed? When I was a kid I just remember Crest, Aim and Colgate. I do not remember the different flovers and jobs that certain ones do. Now they even have one to use at night? lol Choices, choices...
