In case you missed this episode of the ubiquitous public radio flagship This American Life, the episode Tell Me I'm Fat is one of the best I've heard in years.
I like to think of myself as a person who tries to be aware of his own biases and works to mitigate them. This episode more clearly illustrated the human cost my bias against fat people helps produce than anything I've read or listened to before.
This isn't a comprehensive deep-dive into all the medical and social aspects of obesity; that would consume far more than an hour. It's a collage of voices, speaking from experience. If you have only a few minutes, listen to Elna Baker's piece (starting around 24:45) about how her life changed when she lost a lot of weight. It starts out rather light hearted, but by the end her honesty is searing and painful.
