For Maribeth
Maribeth, I am very interested in this thread because I have been researching the pros and cons of diets such as Atkins for my own use. I have read all your posts and respect your opinion.
Nancy324 referred to an article, “What If It’s All Been a Big Fat Lie” in the New York Times:

Maribeth, this article made a big impression on me, as did articles and books I read by authors promoting a higher fat diet (like Atkins). You offered to show research that bolstered your arguments. I am hoping you will use that research to address quotes from several prominent sources in the NY Times article because I do admit I found it most convincing.
Eleftheria Maratos-Flier, director of obesity research at Harvard's Joslin Diabetes Center, is quoted as saying, “For a large percentage of the population, perhaps 30 to 40 percent, low-fat diets are counterproductive… They have the paradoxical effect of making people gain weight.''
Richard Veech, a National Institute of Health researcher who studied medicine at Harvard and then got his doctorate at Oxford University with the Nobel Laureate Hans Krebs. “Doctors are scared of ketosis… They're always worried about diabetic ketoacidosis. But ketosis is a normal physiologic state. I would argue it is the normal state of man. It's not normal to have McDonald's and a delicatessen around every corner. It's normal to starve.'' “Veech calls ketones 'magic' and has shown that both the heart and brain run 25 percent more efficiently on ketones than on blood sugar. “
“In the early 70's, J.P. Flatt and Harvard's George Blackburn pioneered the ''protein-sparing modified fast'' to treat postsurgical patients, and they tested it on obese volunteers. Blackburn, who later became president of the American Society of Clinical Nutrition, describes his regime as 'an Atkins diet without excess fat' and says he had to give it a fancy name or nobody would take him seriously. The diet was 'lean meat, fish and fowl' supplemented by vitamins and minerals. 'People loved it,' Blackburn recalls. 'Great weight loss. We couldn't run them off with a baseball bat.’ “
Taubes also cites the results of five studies, including one “led by Gary Foster at the University of Pennsylvania, Sam Klein, director of the Center for Human Nutrition at Washington University in St. Louis, and Jim Hill, who runs the University of Colorado Center for Human Nutrition in Denver. The results of all five of these studies are remarkably consistent. Subjects on some form of the Atkins diet -- whether overweight adolescents on the diet for 12 weeks as at Schneider, or obese adults averaging 295 pounds on the diet for six months, as at the Philadelphia V.A. -- lost twice the weight as the subjects on the low-fat, low-calorie diets.“ “In all five studies, cholesterol levels improved similarly with both diets, but triglyceride levels were considerably lower with the Atkins diet.”
David Ludwig, a researcher at Harvard Medical School who runs the pediatric obesity clinic at Children's Hospital Boston: ''Grain products and concentrated sugars were essentially absent from human nutrition until the invention of agriculture, 'which was only 10,000 years ago.''
Ludwig also wrote an article published in the
Journal of the American Medical Association about what he calls "Endocrinology 101." Taubes summarizes from this article 'that we are simply hungrier than we were in the 70's, and the reason is physiological more than psychological. In this case, the salient factor -- ignored in the pursuit of fat and its effect on cholesterol -- is how carbohydrates affect blood sugar and insulin. In fact, these were obvious culprits all along, which is why Atkins and the low-carb-diet doctors pounced on them early."
Ludwig does not recommend the Atkins diet because he says he believes such a very low carbohydrate approach is unnecessarily restrictive; instead, he tells his patients to effectively replace refined carbohydrates and starches with vegetables, legumes and fruit.
Maribeth, I found this most interesting, since this is exactly the diet Atkins recommends after his dieters finish Induction and move on to a maintenance diet. In fact, (from what I’ve read) I do respectfully submit that you might be incorrect to say Cynthia isn’t doing real Atkins, because her consumption of brown rice and fruit is allowable on the maintenance diet. Again, I say this with the greatest of respect, because you are obviously well-educated on this subject and I may indeed be wrong.
But from what I’ve read, it all depends on a person’s tolerance for carbohydrates. Atkins allows as many good quality carbs as a person can take without them starting to gain weight again. For athletes and highly active people, this would of course mean they could consume more carbohydrates than sedentary individuals and therefore still be “doing Atkins” without it being detrimental to peak performance.
Regarding cholesterol, Taubes claims that the National Institute of Health used shoddy science when “they had failed to demonstrate at great expense that eating less fat had any health benefits. But if a cholesterol-lowering drug could prevent heart attacks, then a low-fat, cholesterol-lowering diet should do the same,” a hypothesis that fueled the “low-fat diet is good for you” campaign.
I realize you have a real life, Maribeth, and I have included many quotes. (I did cut several out to shorten this post!) Please answer at your convenience. I thank you for all your past and future input on this issue. And now, I will go back to lurkdom!
