“ Hunger: A Memoir of (My) Body” is no weight-loss memoir, she is quick to explain. Instead, it’s a searing account of the essayist’s lifelong struggle with her weight, which once topped 500 pounds. “The story of my body is not a story of triumph,” Gay writes in the opening pages. Roxane Gay begins her new book - the hardest she’s ever had to write - by describing what it isn’t. Roxane Gay set out wanting to write about fat, but she “started to think, ‘Well, what would it be like to write a memoir of my body?’ ” (Jay Grabiec)
