Um NYT, Reuters and AP just announced the scientific study. Give
me a break instead of nit-picking.

Are you trying to compare a starving Ethiopian to a overly healthy north American?

um read what I said. North Americans 100 years ago had the same diet. Europeans had a vegetable and carb-rich diet. Do I really need to compare the Atkins diet to a starving Ethiopian. Give me a break. I only have to look at history and anthropology to figure that out. I never made a normative statement that claimed Atkins was unhealthy, rather that it was an enormous change in diet. I said "Its too big of a difference for me"

You then state a qualifying remark......."...but even in short periods of Atkins eating (as weightlifters do), there is no evidence to show that it is safe conclusively. Sorry....you are misinformed again. Debate the merits anyone?

Im sorry but I did not include the word "conclusive". The science that you quote is a collection of studies that fail to look at a number of factors. Here is a review of the major supporting studies as provided by Atkins.com
<u>Atkins</u>
====Abbasi, F., McLaughlin, T., Lamendola, C., et al., "High Carbohydrate Diets, Triglyceride-Rich Lipoproteins, and Coronary Heart Disease Risk," The American Journal of Cardiology, 85, 2000, pages 45-48.
Only looked at the overall cholesterol with a controlled diet that was very low in cholesterol. Did not look at Kidney, liver, or Pancreas. The diet was only performed for a year and no follow-up checks were done after a year.
====Ball, S.D., Keller, K.R., Moyer-Mileur, L.J., et al., "Prolongation of Satiety After Low Versus Moderately High Glycemic Index Meals in Obese Adolescents," Pediatrics, 111(3), 2003, pages 488-494.
only looks at insulin responses in adolsecents. Short study period.
====Bravata, D.M., Sanders, L., Huang, J., et al., "Efficacy and Safety of Low-Carbohydrate Diets: A Systematic Review," The Journal of the American Medical Association, 289(14), 2003, pages 1837-1850.
The
Atkins Website quotes the conclusion of the
The Journal of the American Medical Association study,
"There is insufficient evidence to make recommendations for or against the use of low-carbohydrate diets, particularly among participants older than age 50 years, for use longer than 90 days, or for diets of 20 g/d or less of carbohydrates. Among the published studies, participant weight loss while using low-carbohydrate diets was principally associated with decreased caloric intake and increased diet duration but not with reduced carbohydrate content."[/b]
Also interesting is that the synthesis was from a number of studies, none of which had a test period of more than a year "The included studies were highly heterogeneous with respect to design, carbohydrate content (range, 0-901 g/d), total caloric content (range, 525-4629 kcal/d),
diet duration (range, 4-365 days)...
Only 5 studies (nonrandomized and no comparison groups) evaluated these diets for more than 90 days."
What Atkins.com does not mention is that
the conclusion drawn by Bravata, Sanders and Huang is based on a whopping 107 studies.
====Brehm, B.J., Seeley, R.J., D’Alessio, D.A., et al., "Effects of a Low Carbohydrate Diet on Body Weight and Cardiovascular Risk Factors", College of Nursing and College of Medicine, University of Cincinnati. Also appears as Brehm, B.J., Seeley, R.J., Daniels, S.R., et al., "A Randomized Trial Comparing a Very Low Carbohydrate Diet and a Calorie-Restricted Low Fat Diet on Body Weight and Cardiovascular Risk Factors in Healthy Women," The Journal of Clinical Endocrinology and Metabolism, 88(4), 2003, pages 1617-1623.
6 month study, 3-months of follow up. Still less than a year. They conclude that "These results indicate that for short periods of time, a low carbohydrate, ketogenic diet is efficacious in causing weight loss and has no deleterious effects on cardiovascular risk factors. " but they do not even try to claim that the study applies to long-term use of the Atkins diet.
====Brown, R.C., Cox, C.M., "Effects of High Fat Versus High Carbohydrate Diets on Plasma Lipids and Lipoproteins in Endurance Athletes," Medicine and Science in Sports and Exercise, 30(12), 1998, pages 1677-1683.
three months of eating Atkins, all people tested were athletes and a low-cholesterol diet was used. They also only got 50% of their calories from fat which is fairly low for Atkins. The study concludes a very vague and uninteresting, "According to this study, a high-fat diet may not have adverse effects on performance or blood lipid profiles. Including up to 50% total calories as fat had no negative effects on the total and LDL cholesterol levels of well trained athletes"
====Campbell, L.V., Marmot, P.E., Dyer, J.A., et al., "The High-Monounsaturated Fat Diet as a Practical Alternative for NIDDM," Diabetes Care, 17(3), 1994, pages 177-182.
Only ten test subjects. All with mild NIDDM. They concluded "the HM diet was,
in the short-term, metabolically better in some aspects than the currently recommended diet for NIDDM"
Brehm, B.J., Seeley, R.J., Daniels, S.R., et al., "A Randomized Trial Comparing a Very Low Carbohydrate Diet and a Calorie-Restricted Low Fat Diet on Body Weight and Cardiovascular Risk Factors in Healthy Women," The Journal of Clinical Endocrinology and Metabolism, 88(4), 2003, pages 1617-1623.
Ten days of eating higher-fat diets doesnt cause any damage. This study was quoted by the LA Times as "Atkins study finds that higher fat diet is healthy for Diabetics" which is grossly over-labeled.
====Coulston, A.M, Liu, G.C., Reaven, G.M., "Plasma Glucose, Insulin and Lipid Responses to High-Carbohydrate Low-Fat Diets in Normal Humans," Metabolism, 32(1), 1983, pages 52-56
The study covered only 11 people and a diet of 10 days. They conclude (with only ten days of research) that diets too high in carbs are unhealthy. This is great to know, but the debate really is between Atkins and balanced diets.
====Dreon, D.M., Fernstrom, H.A., Miller, B., et al., "Low-Density Lipoprotein Subclass Patterns and Lipoprotein Response to a Reduced-Fat Diet in Men," The FASEB Journal, 8(1), 1994, pages 121-126.
"One hundred five men a consumed two diets for six weeks each. " supports the idea that too many carbs are bad for the heart but again is only short-term.
====Dreon, D.M., Fernstrom, H.A., Williams, P.T., et al., "A Very-Low-Fat Diet Is not Associated With Improved Lipoprotein Profiles in Men With a Predominance of Large, Low-Density Lipoproteins," American Journal of Clinical Nutrition, 69, 1999, pages 411-418.
They conclude that cutting back severely on fat isnt necessarily helpful for people with heart disease.
"Thirty-eight men were assigned to follow their "usual" diet (comprising 35% fat) or a very-low-fat diet (less than 10% calories from fat)
for 10 days each" Again it is short-term
====Dreon, D.M., Frey-Hewitt, B., Ellsworth, N., et al., "Dietary Fat: Carbohydrate Ratio and Obesity in Middle-Aged Men," American Journal of Clinical Nutrition, 47, 1988, pages 995-1000.
supports the claim that Atkins helps people lose weight, but we already knew that. It also concludes that "
Men who ate more calories from carbohydrate and plant protein tended to have a lower percentage of body fat"
====Facchini, F.S., Saylor, K.L., "A Low-Iron-Available, Polyphenol-Enriched, Carbohydrate-Restricted Diet to Slow Progression of Diabetic Nephropathy," Diabetes, 52(5), 2003, pages 1204-1209.
Cutting carbs is the real element in reducing diabetes risk, instead of increased protein. Protein still helped and they did not test diets with higher fat content.
====Fagan, T.C., Oexmann, M.J., "Effects of High Protein, High Carbohydrate, and High Fat Diets on Laboratory Parameters," Journal of the American College of Nutrition, 6(4), 1987, pages 333-343.
high-protein diets have high-glucose levels which can impede weight-loss. Not a big deal.
====Farnsworth, E., Luscombe, N.D., Noakes, M., et al., "Effect of a High-Protein, Energy-Restricted Diet on Body Composition, Glycemic Control, and Lipid Concentrations in Overweight and Obese Hyperinsulinemic Men and Women," American Journal of Clinical Nutrition, 78(1), 2003, pages 31-39.
Strangely the study found that
"Weight loss (7.9 +/- 0.5 kg) and total fat loss (6.9 +/- 0.4 kg) did not differ between diet groups."
"Replacing carbohydrate with protein from meat, poultry, and dairy foods has beneficial metabolic effects and no adverse effects on markers of bone turnover or calcium excretion."
They also were less than six months.
====Foster, G.D., Wyatt, H.R., Hill, J.O., et al., "A Randomized Trial of a Low-Carbohydrate Diet for Obesity," The New England Journal of Medicine, 348(21), 2003, pages 2082-2090.
"The low-carbohydrate diet produced a greater weight loss (absolute difference, approximately 4 percent) than did the conventional diet for the first six months, but the differences were not significant at one year. "
Longer and larger studies are required to determine the long-term safety and efficacy of low-carbohydrate, high-protein, high-fat diets.

I see lots of studies that conclude that diets that are too high in carbs are bad, but I dont see any study that has lasted any significant amount of time that concludes that Atkins is healthier. I also see no long-term study that finds that Atkins is healthy over a long period of time. It's a little abusive for me to make you find one, but you called me "misinformed" so I guess justification is your burden there. Im curious. If I really missed a study with a large sample size that lasted more than a year that concluded that a continued Atkins diet is safe then I will apologize and admit to being misinformed.
