[Lemon:] OK, just in time for your new year's diet, because I know a lot of you are going to do that. Jenny Craig has made some changes in the weight loss plan. Participants in a new program called "Metabolic Max" will get light weight arm bands that track physical activity and calories burned. That's supposed to keep people honest about how much exercise they actually get. The move comes one month after weight watchers made some changes of its own. It fine tuned points system to consume differences, not just calories. But choosing a diet is never easy, of course. And just to make things more complicated, there appears to be a new diet war between the long-established Atkin's diet and the upstart called the Dukan diet. CNN Senior Medical Correspondent Elizabeth Cohen joins us from Miami. Is the Dukan diet or the "duck-en" diet?
[Dr. Elizabeth Cohen, Cnn Senior Medical Correspondent:] We can't reach them. We can't confirm the pronunciation. But it seems like most people are called it the "due-kan" diet.
[Lemon:] So what's going on here?
[Cohen:] It's really interesting. It is the spirit of the late Dr. Robert Atkins, the founder of the Atkins diet, versus Carol Middleton, the mother of the future queen of England. She's been talking about the Dukan diet and how it's done her so much good and how it's helped her lose weight. And you can see she's looking pretty trim. And the Atkins people are none too happy. They said the Dukan diet is trying to copy the Atkins diet but isn't as good as the Atkins diet. In fact the Atkins people sent out a press release with some pretty harsh words. They said that the Dukan diet has "nutritional recommendations that simply don't make sense or are guaranteed to fail." That's pretty strong language "guaranteed to fail." Don?
[Lemon:] Well, I don't understand. So why can't there's only so much you can eat and probably different patterns in which you can eat. Before the Atkins diet, there was the Stillman Water diet, which was basically low or no carbohydrates. Do they own the patent to low- carb diets?
[Cohen:] They seem to think that this is their diet and other people are sort of taking it from them. And I agree with you. I think each diet is just a slight reincarnation of the next diet. But let's talk a little bit about what the Dukan diet is because I think people are familiar with Atkins. It's a high-protein diet, also has four phases like Atkins. And the first phase is you only eat high-protein foods, second phase, you add vegetables every other day. The third phase you reintroduce what they call pleasurable foods. I guess that means carbohydrates and desserts and what not. And then phase four, you eat what you want with some restrictions. And their motto is "Eat as much as you like and forget about cutting calories." The Atkins people say "eat as much as you like," that is a recipe for failure. They said that just can't work and they say Atkins is much more structured.
[Lemon:] OK. So now we know. All right, Elizabeth. Thank you. We appreciate Elizabeth Cohen, our senior medical correspondent. And she is in Miami.
