In Rock What You've Got, Katherine Schwarzenegger tells of growing up as the daughter of both a famous bodybuilder-turned-blockbuster celebrity and a mother who also built a successful career in front of the camera. Katherine's mother, Maria Shriver, faced her own pressures growing up under the strict food rules of mom Eunice Kennedy Shriver, who was 5-foot-9-inch tall and never weighed more than 100 pounds during most of her adult life.

As a result, "Mom never forced us to eat or stop eating," she writes. "She never policed us."

Her father, on the other hand, is remembered much more as a food watchdog. He was more prone to ask, "Are you sure you need that second helping?" and point out how many calories were in the muffin she was eating. And it was no fun for the kids in the house when he was gearing up to film a movie and would tear through the house, trashing all the ice cream and junk food, his daughter told the campus magazine at the USC Annenberg School for Communication & Journalism, where she expects to complete her degree in 2012.

She also writes how she felt growing up as a Kennedy - revealing that she felt like a misfit during summers at her family's compound on Cape Cod. The hairstyle, multiple earrings and dark nail polish she wore to express herself in LA made her feel "a little like the black sheep in my conservative extended family," she writes. The questions and criticism from her cousins made her feel "insecure and lost."

But she credits her parents with the strict but supportive upbringing that made her feel secure and ultimately steered her toward mature decisions.
