No but Elisabeth jumps out a window, falls off a horse and jumps from a ship into the sea (this last one is the closing image of the films so her fate is left ambiguous, but in reality she didn’t die)
The film is not about her eating disorder but it is a frequent theme. Elisabeth restricts (it is shown several times) and instructs someone else to toward the end. People gossip about her weight (and her appearance in general) and she is insecure about her appearance
