I think of the internet as a vast ocean of sewage with a few beautiful little islands scattered here and there. The problem is that swimming through the muck to find those islands is no fun. So consider the links offered here as round-trip airfare to some pretty decent weight loss websites.
The websites I have chosen to link here include those run by government (Federal, State and local), by universities and teaching institutions, by non-profit corporations and, in some cases, by the food industry itself. This is not an exhaustive list and new websites are springing up all the time, so please feel free to alert me if you find material I have overlooked. I've tried to group the sites and the help they offer into logical categories linked below.
