...Sieger, 34, a research associate at a Houston-based biomedical research firm, has turned to the Atkins diet, a weight-loss program that seems to defy nutritional wisdom. Most health experts advise you to favor carbohydrates, found in everything from fruits to grains, while going easy on the protein and fat. On the Atkins diet, one is allowed to eat all the protein- and fat-drenched meat and butter one wants but must cut out cereal and bread. And if Sieger is puzzled by certain aspects of the diet--among other things, the initial phase is so low in fiber...
Sieger is just one of the latest wave of Americans willing to try a regimen first promulgated by Dr. Robert Atkins three decades ago. His is the diet that refuses to die, slipping in and out of favor every few years, persistently bucking the skepticism of mainstream nutritionists. Could it really be, as Atkins argues, that low-fat diets, which are typically high in carbohydrates, are bad and that low-carbohydrate diets, which often contain considerable fat, are good? Is it really O.K., as Atkins advocates, to slather mayonnaise all over salmon and tuna and douse asparagus and lobster with...
...carbs, Ornish vs. Atkins. But here is what is new and somewhat startling: there are hints that Atkins may have struck a vein of truth--hints that are intriguing enough to convince some mainstream obesity experts that the approach merits more serious consideration. "Is it just that the Atkins diet is monotonous, and so people eat fewer calories?" wonders Dr. Samuel Klein, director of the Center for Human Nutrition at Washington University in St. Louis, Mo. Or is there something more interesting going on? Something unexpected about food itself, perhaps, or the way we eat it or even what...
...course, the mere suggestion that the Atkins diet and others like it are worthy of scientific attention still makes many experts bristle. Yet it is also clear that the low-fat paradigm has developed some cracks in its facade. It turns out that not all fats are bad for you. Those found in fish, nuts and certain vegetables may actually increase your chances of living a good long life. By the same token, not all diets that are low in fat are necessarily healthy--as anyone who has ever truly considered the difference between a low-fat banana cream...
...level, there is no mystery about why we as a society are fat. We are fat because we consume too many calories and expend too few. Though it is true that the proportion of fat in our diet has fallen from 40% in 1990 to roughly 34% today, the calories available in the food we consume have gone up, from 3,100 calories per capita per day in the 1960s to 3,700 in the 1990s, according to the U.S. Department of Agriculture (USDA). "And that alone," says New York University nutritionist Marion Nestle, "is sufficient to explain the obesity...
