On a mission to turn losing weight into a positive experience, Rick Gallop recruited volunteers with a body mass index of 33 or over–in other words, the hard cases–to participate in an e-clinic he would run from his website. For 13 weeks he introduced them to the basics of the G.I. Diet, answered their questions, taught them how to shop, cook and eat out, coached them through the hurdles and helped them develop strategies for dealing with cravings and the emotional reasons why we eat.
