Atkins wins ... sort of.An Atkins diet Atkins Diet Definition The Atkins diet is a high-protein, high-fat, and very low-carbohydrate regimen. It emphasizes meat, cheese, and eggs, while discouraging foods such as bread, pasta, fruit, and sugar. It is a form of ketogenic diet.

Of or relating to the years or the stage of life immediately before the onset of menopause. premenopausal adjective women (they averaged 187 pounds) to one of four diets: * Atkins: no more than 20 grams of carbs a day for the first 2 to 3 months and 50 grams a day later. * Learn: limited calories, 30 percent of calories from fat, more exercise. * Ornish: only 10 percent of calories from fat. * Zone: limited calories, 40 percent of calories from carbs, 30 percent of calories from protein, 30 percent of calories from fat. Despite those goals, by the end of one year the participants were eating fairly similar diets. Among the differences that remained: carbs were lower (138 grams a day) in the Atkins dieters than in the others (180 to 200 grams a day). And fat was higher (44 percent of calories) in the Atkins dieters than in the others (30 to 35 percent of calories). The results: After one year, the Atkins dieters had lost more weight (10 pounds) than those who followed LEARN (6 pounds), Ornish (5 pounds), or Zone (4 pounds). And all four groups had regained some of the weight they lost after the first six months they were on their diets.

LDL LDL - ["LDL: A Logic-Based Data-Language", S. Tsur et al, Proc VLDB 1986, Kyoto Japan, Aug 1986, pp.33-41]. ("bad") cholesterol didn't change significantly in any group.
