Americans are gluttons for diet fads. The trouble is, trendy diets—no matter how effective in helping you lose weight—usually fail when it comes to keeping the weight off. And most impose so many restrictions that they make eating a grim duty. The G.I. Diet Cookbook pursues a much more enjoyable strategy. Its 100-plus recipes, created by British food celebrity Antony Worrall Thompson, emphasize satisfaction, not deprivation. The glycemic index focuses on the benefits of low-G.I. foods from every category, including carbohydrates. Because they’re slow to digest, low-G.I. foods make you feel less hungry, allowing you to shed pounds effortlessly. And because the book’s dishes are so varied and delicious, maintaining weight loss is easier than ever before. The G.I. diet is rooted in sound nutritional principles that have long been used by diabetics to control their weight and blood sugar. But Thompson’s culinary ingenuity—and his devotion to preparing food that’s as tasty as it is healthy—has transformed this formerly "medical" diet into one that everyone will find irresistible.
