What do you mean, outdated? Schwartzbein Principal, Protein Power, Carb Addicts Diet, Sugarbusters... all are valid, proven plans with many satisfied followers. Snoop around the forums for each, and you'll likely find someone with the same goals and requirements who are having a GREAT experience with them and would be happy to give you plenty of information on their personal experiences on them.

There really is nothing new under the sun... the flashy, overhyped "new and improved" plans coming out now are basically variations on a theme...
