"They didn't get everything right," Louise Foxcroft, author of Calories and Corsets: A History of Dieting Over 2,000 Years, told Gastropod, "but they did know that a healthy mind and a healthy body made for a healthy society"—for individuals and for society. So the onus on diet and on having an ideal body—it's always been a much more difficult concept for women, and that's reflected in our modern diet culture as well." And she has developed her own diet, the iDiet, which she notes is the only diet program ever clinically shown to reduce hunger during weight loss.
