But some strains of rats, perhaps most of them, willnot grow obese on high-fat diets, and even those that do will grow fatter on a high-fat, high-carbohydrate diet than a high-fat, low-carbohydrate diet. Moreover, to induce obesity even in susceptible rodents, the percentage of fat in the diet has to be greater than 30 percent, and usually closer to 40 or even 60 percent (which still makes only some strains of rats fat). Though 30 percent sounds like a low-fat or moderate-fat diet for humans, it’s far greater than anything rats would normally consume, either in the wild or in the laboratory. It’s what researchers will call apharmaceutical dosage of fat. Rat chow is typically 2–6 percent fat calories. Rats will also fatten when fed large amounts of carbohydrates in the form of sugar. Moreover, other animals fatten on carbohydrates, including pigs—whose digestive apparatus is most like that of humans among experimental animals—cattle, and monkeys.

I had now read four memoirs, all strikingly different in their depictions of the visual experience of blinded people: Hull with his acquiescent descent into“deep blindness”; Torey with his “compulsive visualization” and meticulous construction of an internal visual world; Tenberken with her impulsive, almost novelistic visual freedom, along with her remarkable and specific gift of synesthesia; and Lusseyran, who identified himself as one of the “visual blind.” Was there any such thing, I wondered, as a typical blind experience?
