Reports have surfaced of a professor with a mania for self-examination. His line of inquiry, however, is not of the Socratic philosophical sort. An expert in computer science, he is collecting data on his bodily functions. To improve his diet (and reduce his weight) he tracks what he eats down to the calorie. He straps sensors to his body to measure his caloric burn while exercising. Unsettlingly, it has been reported, the professor “is deep into the biochemistry of his feces . . . [keeping] detailed charts of their microbial contents [and has] been known to haul carefully boxed samples out of his kitchen refrigerator to show incautious visitors.”
It would be easy to wave off this news as nothing more than another sideshow in the human carnival. But after reading The Metamorphoses of Fat, the case of the coprological computer scientist seems less strange. Indeed, instances of eggheads obsessing over their bodily inputs and outputs go way back. Sanctorius, a professor at Padua during 1611-24, erected a “weighing chair” and, for 30 years, used the room-sized contraption to tabulate his weight and attribute the fluctuations to what he consumed and excreted. The research methods may be peculiar, but the topic of study is not idiosyncratic: Who among us has not counted calories or tried a diet (South Beach, Atkins, paleo, etc.) in the hopes of improving one’s appearance, elevating one’s energy, lengthening one’s life? The quest to comprehend the relationship between eating and health is commonplace.
George Vigarello shows, often amusingly, that the Western world has always drawn associations between human constitution and the size and weight of the body. Whether being fat or thin or somewhere in between was desirable has depended on the basis for the judgment. The dearth of real knowledge as to the operations of the body invited conclusions based on a variety of factors.
At the dawn of the second millennium, for example, overweight men were derided as womanly or weak. Thus, William the Conqueror was mocked for being so fat that he looked pregnant. The French King Louis VI (“the Fat”) was ridiculed in 1135 for being too portly to mount a horse. Very different conceptions of fitness came to the fore in the 14th and 15th centuries: Europe was a world of “hunger, severe restrictions, and food shortages.” Failed harvests, the plague, and other pestilences, as well as crushing poverty, generally contributed to “raising the accumulation of calories into an ideal.” Paradise was imagined as a place where “beer and wine flow like rivers [and] stews and roasts seem to pop out of the soil.” For men, a big belly was a sign of vitality. Long before Rubens, artists celebrated corpulent women. The 14th-century Parisian’s Household Manual (known in English as The Good Wife’s Guide) states that both horses and women should have “beautiful loins and big bottoms.” The fat woman was the fertile woman; the thin one was imagined to be barren.
The aesthetics of body shape varied widely for the next few centuries. The stout were sometimes considered mighty and at other times sick. The scrawny were never considered powerful and were sometimes thought feeble or diseased. Words were invented to distinguish between desirable and undesirable amounts of fat. The French term rondelet, for example, appeared in the “middle of the 16th century to designate a moderate, entirely ‘natural’ roundness.” Meanwhile, lourd conveys an undesirable thickness and torpor.
Notions of virtue and vice entered the mix. Fatness became associated with greediness. Rolls of heft indicated insatiability, an “infinity of oral desire” that demonstrated moral degradation and slovenliness. Class also became a consideration. Fatness went from being a trait of the wealthy to a characteristic of “fieldworkers and mule drivers.” The image of the lower class as obese, ham-fisted brutes became popular by the 17th century: “Beautiful Alison,” a sardonic song from 1633, mocks Alison for having “chubby arms like a mustard barrel” and “a stomach [like] a frozen cabbage.” Not long after, depictions of potbellied bankers and plutocrats flooded paintings and cartoons.
