First they called Tyra fat. Then they called the cast of "Gossip Girl" curvy. But now the absurd preoccupation with thinness has reached the animal kingdom.

Nineteen dolphins at a Japanese marine park were put on a low-fat diet when their daily performances reportedly suffered due to weight gain. The plump porpoises reportedly added about 22 pounds of girth over the summer and have since "started failing to hit jumping targets and keep upright while treading water."

The suspected culprit? Fatty mackerel.

According to the park spokesman, the trainers have put the dolphins on an exercise regimen and started them on a modified diet featuring low-cal treats like whitefish. So far, it seems to be working.
