"Want to know the secret to losing weight? Eat less and exercise more. Not sold? Join the club. Bookstores are brimming with shelf upon shelf of diet books, all offering their own strategies for making that spartan prescription a bit easier to stomach."

"The king of the bestseller list, "Dr. Atkins' New Diet Revolution" (HarperCollins, 2002), and brainchild of now deceased cardiologist Robert Atkins was first published in 1972 and sparked a low-carb, high-protein nationwide craze. The idea behind the diet is that restricting carbs -- the body's preferred source of energy -- prompts it to burn fat instead. Despite criticism by the medical community that the diet is unhealthful, at one point a few years ago, Americans, at the rate of 1 in 6, were turning up their noses at hamburger buns and heading straight for the burger."

"Previous research also has suggested that the Atkins plan makes it easier to lose weight, and a new study lends credence to that notion. Writing in the Journal of the American Medical Association, researchers at Stanford University compared four popular, brand-name diets, with Atkins coming out slightly ahead. The study participants who gobbled up the steak, eggs and cheese also fared better on cholesterol and blood pressure measures than those on the other diets."

"What's more, the women assigned to the Atkins diet lost a tad more weight. Yet experts were surprised by how little, on average, that was: just over 10 pounds, from a starting weight averaging 190 pounds. And those were the biggest losers. Women on the other diets lost less than 6 pounds. Many experts don't see the study endorsing Atkins but rather underscoring how tough a chore it is to shed inches."

""There's no easy solution and no magic formula as far as weight loss goes," says Alice Lichtenstein, a nutritional biochemist with the Friedman School of Nutrition Science and Policy at Tufts University, Medford, Mass."

"The other three diet regimens the researchers examined include the Zone diet by Barry Sears, a biochemist and nutrition scientist, favoring a 40-30-30 percent balance of carbs, protein and fat, and the diet developed by internist Dean Ornish, which calls for lots of good carbs and no more than 10 percent of calories from fat. Lastly, the researchers included the LEARN (Lifestyle, Exercise, Attitudes, Relationships and Nutrition) program, which adheres to the U.S. Department of Agriculture food pyramid and promotes a diet of about 60 percent carbs and less than 10 percent saturated fats."

"The study participants, 311 premenopausal women who were obese or overweight with an average age of 41, received some initial hand-holding. But after eight weekly classes, they were on their own, armed with only the diet book to guide them."

"By year's end, the average weight loss was just over 10 pounds for the Atkins group, almost 6
