Jillian gets a full physical

5 of 7
Having survived Dr. Oz and Dr. Roizen's surprise house call, Jillian had a complete physical exam at Dr. Roizen's center at Northwestern Memorial Hospital in Chicago. She underwent a stress test and met with a dermatologist and an allergy specialist.

When Jillian gets her test results, she's shocked. "Your calendar age is 42.6, as you know," Dr. Roizen says. "But your Real Age is 56."

"When he said I was 56, that was harsh," Jillian says. "It's like someone walking up to you and asking you when the baby's due and you're not pregnant."
