Chances are if you dine out with Dr. Mehmet Oz, he won’t be staying for dessert.

“One of my pet peeves with restaurants is when they push dessert. It’s metabolic suicide,” Oz told me recently after the taping of "The Dr. Oz Show" on NBC at Rockefeller Center in New York City. As one of the studio audience participants, I got to watch Dr. Oz in action and gain a better understanding of his media mission to help viewers improve their lives.

“We try to get people into wellness," he said. "But it’s not really a health show. It’s about life.”

Topics on the show this day included the body pains you shouldn’t ignore, tips on buying food and health products in bulk and discerning which outrageous alternative health treatments are actually legitimate. Hint: leeches can play an important role in modern medicine.

Assertive with Oz

Now about that dessert. Oz, who is a cardiac surgeon as well as vice-chair and professor of surgery at Columbia University, is concerned about the significant health consequences of obesity in America. But, he says, “It’s really a 100 calorie problem.”

He explains that by cutting 100 calories when you can (i.e., skipping dessert) or by burning 100 calories through exercise, most folks can prevent weight gain.

“You need assertiveness training to dine out," he said. "You have to ask the waiter not to bring the bread and butter. Look online at the menus ahead of time. Even fast food restaurants have healthier options today.”

And if you can’t find a healthier version of your favorite restaurant food, "The Dr. Oz Show" can show you how to make your own at home.

Do you like fried rice? In a segment called “Fake Out -- Take Out,” a Dr.Oz fan prepared a lightened up version of shrimp fried rice that featured edamame beans, quinoa and ponzu sauce, which is lower in sodium than soy sauce. Audience members tasted and approved.

“Number one, you have to give them foods that they like, foods that taste good and happen to be good for you," Oz said. "The ponzu sauce was a smart idea.”

Calorie savings shared on the show revealed that a typical order of take-out fried rice contains 1,000 calories, while the “Fake Out” lighter recipe contained only 360 calories.

Dr. Oz gained fame as a medical expert on "The Oprah Winfrey Show" for over five seasons and has authored best selling books with Dr. Michael Roizen, including "YOU: On a Diet" and "YOU: Losing Weight." "The Dr. Oz Show" has earned daytime Emmy awards for best informative talk show host in 2010 and 2011.

After observing the morning taping, I met Dr. Oz in his office, where he had changed out of the tailored suit he’d worn for the show and into comfy blue scrubs and a black T-shirt. His was relaxed and welcoming even though he was preparing to tape another episode in the afternoon. I felt as if I was being greeted by a family physician who’d known me for years and told him that’s how he appears when he greets the guests who are "patients" on his show.

“I think that’s something that’s lost in American medicine,” he said, “Someone who knows your parents. It’s about identifying a quilt of symptoms.”

Oz’s lunch

Even though topics presented on his show run the gamut from flossing to fibromyalgia, Oz said, “Good nutrition is the foundation of the show. When I walk into a grocery store I see all of the healthy foods and it’s like a pharmacy.”

I looked at the scripts arranged on his desk and noticed a plate of food. Guess what he was having for lunch? A serving of the winning recipe for healthy alternative take-out -- the shrimp fried rice. How about that? Oz is a doctor who takes his own medicine.
