But Now Am Found by Nina Kiriki Hoffman (F&SF, October-November 1995) sees a woman wake up in her bed to find two other bodies beside her. She realises that they are versions of herself, Fat Self and Little Self. They subsequently keep her captive in her apartment and force feed her:
“Eat,” said Little Self, and it and Fat Self worked together to get her out of bed and into the kitchen. Little Self tied her to a chair with clothesline, and Fat Self cooked pancakes. The kitchen smelled of sizzling butter, and flour marrying eggs and milk. Little Self got out the ice cream Iris had hidden in the tiny freezer compartment, the secret shame she couldn’t resist, even though she had been dieting and exercising rigorously for five years. She still cheated some nights when the loneliness overwhelmed her. Mornings after those nights, she adjusted her exercise regimen to work off the extra calories.
Now Little Self was holding out a spoonful of chocolate chocolate mint. Iris heard her stomach growl. She opened her mouth. p. 95
Later, when the woman is allowed to exercise, she sees Little Self grows larger; this cycle of eating and exercising goes on for some time (the woman is trapped in her apartment, and realises that someone else must be doing her job).
Then, at the end of the story, she wakes up one morning to find they have been joined by a scrawny and starved and crying version of her: the final line is “Overnight, the population of the city expanded. Trails of crumbs led the lost home.”
I have no idea what these final lines have to do with the rest of the story (and, even if I did, I don’t have much interest in surreal fantasy stories about first world problems like dieting or body image).
