DALLAS - I am about to sit down with the next Oprah, and she's white and a surgeon with a funny name-and a he.

I realize the consensus from TV critics seems to be that Dr. Mehmet Oz is not in fact The Next Oprah. That distinction belongs to Ellen. What TV critics ignore is what has turned Oprah into a trusted friend in many American households - not sugary celebrity interviews, but rather real talk about the issues that affect us.

And so the dark horse to replace her should be the heart surgeon who made it OK for us to talk about the shape of our bowel movements, about our worst habits and vices and freely about our health when he first started appearing on her show. He is the perfect blend of knowledge and Oprah-training.

"Because I'm a male and a surgeon, I'm all about fixing things. You have a problem. I want to fix the problem," Dr. Oz said. "It took me a long time to realize you can't fix an emotion. You just have to be there and let people talk. Learning this helped my marriage, helped my practice."

And helped turn his TV show into a raging success. Of course, the question is: Can this be sustained? How many health problems can there be?

"Of course, that is what people are thinking. That is what I'd be thinking," Dr. Oz said, not chafing at all at the question.

This is where growth has been for him, no longer a doctor's TV show but rather a TV show on which he happens to be a doctor. And I am technically his target demographic: female, a mom and a die-hard Oprah adherent.

His goal is to be the doctor whom our parents had, the guy who had time to listen and did more than write prescriptions. And he, like Oprah, is on a mission to fundamentally change how we treat ourselves - mind, body and soul.

"By the time we are 50, two-thirds of how we age will be driven by our lifestyle," Dr. Oz said. "When people realize, 'My goodness, not only do I control it, only I control it.' Because doctors don't change what you put in your mouth. He can medicate you, which is painting over cracks in foundation. He can put mechanical devices in, but those are poor imitations of what you were born with. Only you can be a world expert on your body."

He had me until he said those dreaded words - lifestyle change. What exactly does that mean? Low carb or low fat? Running or yoga? Calories versus foods?

We have been inundated with so much conflicting information that eventually you just figure you should drink water and pray. So Dr. Oz gives his viewers tips every weekday - what to do, the science of it, and the real-life examples of people grappling with it so that you can do your own three-month turnaround. Here are a half-dozen top tips:

1. No carb, low carb, low fat, no fat, Atkins, cabbage soup - whatever your diet ploy is, know it will not work.

Repeat after Dr Oz: Will. Not. Work.

Let that sink in. Take a moment. Mourn all that money spent on various diet books and shakes and memberships. Now embrace what Dr. Oz calls "the biology of blubber."

"What you need to do is give a little nudge," Dr. Oz said. "If you try to do more than that, the biology is smarter than you are. There is no survival in starvation."

He suggests slicing 100 calories a day, which will drop 11 pounds in a year. Not as sexy as some diets but sustainable and in adherence with the biology of blubber.

2. Never travel without snacks, and Ding Dongs are not a snack.

Neither are 100-calorie snack packs, low-fat brownies or really anything in the low-cal, low-fat fake-food category.

Why not is simple, according to Dr. Oz: "They have to put something else in place of that fat. Low-fat foods don't grow on trees. And when they chemically modify food, it becomes a game for you and your mind can't win."
