Dr. Oz and Laura

5 of 8
Laura also stopped at the Cleveland Clinic for a battery of tests with RealAge expert Dr. Michael Roizen. The results? "She actually is living pretty well," Dr. Roizen says. "It turns out she's really lucky. Everything she has is reversible."

A lung scan showed no signs of emphysema or cancer. Laura's stress test and heart scan also looked pretty good, but Dr. Roizen says there's still room for improvement. "It's not optimal, but she'd already started walking for the week and was getting better," he says. Blood tests indicated a few abnormalities, but Dr. Roizen says those are caused by extra weight on her body.

Laura took her test results as good news and has started reversing some of her bad habits. "I get my 10,000 steps in a day. I haven't had an ounce of junk, a bad carb or a sweet," she says. "It's all fruits, vegetables and steel-cut oatmeal."

Laura says she's also added a daily cocktail to her diet—a vitamin cocktail. It's a habit Dr. Oz says she absolutely must continue after a bone scan revealed she has osteoporosis. "Osteoporosis, which is a big problem for folks, starts when you're 20 years of age, not when you're 60 years of age," Dr. Oz says. "So if you're not getting enough vitamin D, you need to supplement that. And if you're smoking, you're going to waste away that bone."
