The Ultimate Health Checklist

After getting some tough love from Dr. Oz and Dr. Roizen, Laura decided to take action. Over the past 12 months, she completely transformed her health by following the Ultimate Health Checklist. So far, she's lost nearly 40 pounds! "[You have] a new lease on life!" Oprah says. "Fantastic."

In fact, Laura's lifestyle changes have added years to her life expectancy. The results of her latest Real Age test show that this 45-year-old now has the health of a 41-year-old woman! "By taking better care of yourself and becoming conscious of the way you live and your choices, you've taken almost 20 years off of your age," Oprah says.

The first thing Laura did to improve her health was kick her nicotine addiction. "I never thought I would quit smoking," she says. "The first couple [of] days were a little rough, but after that, I don't think about it. I don't want one. I don't want a puff."

Next, Laura overhauled her diet. "I would say that my diet was absolutely horrific, [a] kill you kind of diet," she says. "It was nothing but grease and fat." These days, Laura starts the morning with a cup of coffee and a bowl of steel-cut oats or a cup of yogurt mixed with fresh fruit. "My fruit of choice for breakfast is blueberries—high in antioxidants," she says. "I sprinkle my food with the flaxseed meal. Flaxseed is high in omega-3 s. It's a good fat."

No healthy lifestyle is complete without a commitment to exercise. Laura says she's stopped taking the elevator and instead walks up five flights of stairs. "It's very important for me to maintain my 10,000 to 15,000 steps a day," she says. "A year ago, I could not have thought ever of coming up five flights of stairs. Now. it's a piece of cake."

Laura is also dealing with stress differently. "Before when I was stressed out, it was a smoke-a-thon," she says. "I would smoke and smoke and then eat and eat." Now, Laura says she takes a walk or meditates when times get tough. "It's a mind-body-spirit thing going on here," she says. "Your mind's better, your spirit's better. I'm calm. I'm relaxed. I just feel good."

If you want to feel better and start living your best life, Oprah says to start by answering one question: Why you are worthy of getting healthy this year?
