The Barbi Twins are Back!

The Barbi Twins are back with a new one two punch - reinventing health and weight maintenance while saving animals.

Infamous for their beauty and bulimia, the ladies let TMZ in on the "Things People Don't Know About Them", "Eating Disorders" and their new book entitled "The Eco-Anti Diet."

The Twins hope the book encourages people with compulsive eating issues, by helping to boost their metabolism and re-shape their body. All proceeds from the diet book go to animal rescue charities.

Catch a glimpse of the Barbi Twins talking about their new book, a clip of an animal rights film project they are consulting on featuring Howard Stern's girlfriend Beth Ostrosky and a new calendar the twins created featuring animals rescued from Hurricane Katrina.

And don't worry, we have the Barbi Twins pin-up calendar too (like we would leave that out).
