Overindulge this holiday season? You may have just powered your next road trip.

A Beverly Hills plastic surgeon decided to turn waste fat into biodiesel. Dr. Craig Alan Bittner used the fat from his patients for his Ford SUV and his girlfriend's Lincoln Navigator. Bitter wrote on his now defunct lipodiesel.com, "Not only do they (patients) get to lose their love handles or chubby belly but they get to take part in saving the Earth." Classy.

Bitter faced some big problems for his creative fueling. For starters it’s illegal to use medical waste to power vehicles in California. But that’s not much of a problem anymore, because he closed his practice in November and moved to South America.

Bitter’s big change likely doesn’t have to do with just the health code. It seems that during the gas crisis a few months ago others were also taking advantage of the Krispy Kreme-sourced fuel. Three patients are suing the practice for not only allowing Bittner’s girlfriend and assistant to perform surgeries without a medical license, but also taking too much fat and leaving them disfigured.
