There is absolutely no reason why you can't get all the "healthy" fats you
want on a low carb diet. And, I'm not a nut, though I like them.

Orish is not backed up, by any evidence. Zero. I ate Ornish for years,
and I have better blood chemistry now (low carb) than on Ornish.

Eat whatever you want. Your diet isn't based on solid evidence.
Seriously. Check it out -- do the research. Here are some places to
start (see http://www.lowcarbresearch.org/lcr/results.asp):
High Carbohydrate Diets, Triglyceride-Rich Lipoproteins, and Coronary
Heart Disease Risk (Journal Abstract) Added on: 12/3/2002 Hits: 589
From Stanford University and the journal American Journal of Cardiology,
2000: Stanford researchers compared the effects of two diets. One diet was
high carbohydrate (60%) and low fat (25%). The second diet was lower
carbohydrate (40%) and higher fat (45%). They found that group who ate the
high carbohydrate, low fat diet had higher tryglyceride levels and higher
cholesterol levels. Their LDL ("bad cholesterol") did not change. The
researchers concluded that "...it seems appropriate to question the wisdom
of recommending that all Americans should replace dietary fat with
carbohydrate." [This link takes you to an error page at Science Direct.

Lipids, Carbohydrates, and Heart Disease (Scientific Statement) Added on:
1/30/2004 Hits: 346
From the State University of New York in Buffalo and the journal Metabolic
Syndrome and Related Disorders, 2003: In this excellent summary, three
researchers review the existing data on dietary fat and carbohydrate in
relation to heart disease. They conclude that glycemic load and
carbohydrate intake is clearly related to heart disease and type 2
diabetes. They state, "In view of the above observations about the effects
of carbohydrates on oxidative stress and inflammation, it is of interest
that Dr. Atkins foresaw the potential ill effects of carbohydrates in
terms of atherogenesis and heart disease decades earlier." (Adobe Acrobat

Insulin resistance and Risk for Stroke (Journal Abstract) Added on:
9/26/2002 Hits: 165
From Yale University and the journal Neurology, 2002: Researchers from the
Yale School of Medicine reviewed studies published between 1977 and 2001
that related to insulin resistance and stroke. They concluded that there
is a prevalent connection between chronically high insulin levels (insulin
resistance) and stroke.
Effect of High-Carbohydrate Feeding on Triglyceride and Saturated Fatty
Acid Synthesis (Journal Abstract) Added on: 9/25/2002 Hits: 337
From the Rockefeller University in New York and the journal Proceedings of
the Society for Experimental Biology and Medicine, 2000: A researcher
reviews a series of studies that investigate the connection between high
carbohydrate meals and increased triglyceride levels. The researcher
concluded that very low fat, high carbohydrate diets increases the levels
of triglycerides in the blood in both lean and overweight people. She also
concluded that higher fat diets (30% fat or more) decreases triglyceride
levels. She recommended that public dietary recommendations be revised to
take into account the effects of carbohydrate, especially simple
carbohydrate, on triglyceride levels.
Relationship Between Obesity, Insulin Resistance, and Coronary Heart
Disease Risk (Journal Abstract) Added on: 9/18/2002 Hits: 238
From Stanford University and The Journal of American College of
Cardiology, 2002: A group of Stanford researchers, including Dr. Gerald
Reaven, studied the effects of obesity and insulin resistance on cardiac
disease. They measured insulin levels, glucose levels, blood pressure,
total cholesterol, triglycerides, HDL and LDL cholesterol levels in the
study volunteers. They concluded that a chronically elevated glucose level
(insulin resistance) is a risk factor for both cardiac disease and
diabetes that is as powerful as obesity.
Insulin, Insulin-Like Growth Factors and Colon Cancer: A Review of the
Evidence (Journal Abstract) Added on: 7/10/2002 Hits: 284
From Harvard University and The Journal of Nutrition, 2001: This Harvard
researcher reviewed over 250 studies relating to insulin and insulin-like
growth factors and their affects on colon cancer growth. He concluded that
there is strong evidence that high carbohydrate intake and high insulin
production fosters colon cancer growth.
Dietary Fat Intake and Endogenous Sex Steroid Hormone Levels in
Postmenopausal Women (Journal Abstract) Added on: 8/25/2003 Hits: 116
From Harvard University and the International Union Against Cancer
Information Services, 2000: A team of researchers from the Harvard
Department of Nutrition studied 381 postmenopausal women for 4 years. They
reviewed the association between the women's intake of dietary fat and
their levels of sex hormones, including estrogen. They found that there
was no association between dietary fat intake and elevated estrogen. In
fact, they found that the *less* dietary fat the women in the study ate,
the more likely they were to have elevated estrogen, quite to the surprise
of the researchers. They concluded that these results are "inconsistent
with the hypothesis that fat intake predisposes to breast cancer risk by
raising endogenous estrogen levels.
The Healing Power of Your Fork: A Brain Tumor Survivor's Eating Plan
(Advisory Statement) Added on: 7/11/2002 Hits: 556
From The National Brain Tumor Foundation, 2002: This national foundation
instructs brain tumor survivors to avoid sugars and other high fiber, high
glycemic foods because of the scientific evidence that sugar accelerates
tumor growth. They also warn patients to avoid low fat diets because of
evidence that selected dietary fats are beneficial in slowing tumor growth
and decreasing siezure activity. (Adobe Acrobat Reader required) If you

Changes In Renal Function During Weight Loss Induced by High vs
Low-Protein Low-Fat Diets in Overweight Subjects (Journal Abstract) Added
on: 7/12/2002 Hits: 1558
From the Royal Veterinary and Agricultural University, Denmark and the
International Journal of Obesity, 1999: The researchers conducted this
study to assess the renal affects of high vs low protein diets. They found
moderate adaptive alterations in renal size but found no indications of
adverse affects on kidney function.
A Randomized Trial of a Low-Carbohydrate Diet for Obesity (Journal
Abstract) Added on: 6/26/2003 Hits: 2253
From the University of Pennsylvania Medical Center, Washington University
in St. Louis, The University of Colorado, and The New England Journal of
Medicine, 2003: These multi-center researchers conducted a 12 months study
of a low carbohydrate, high protein diet with the conventional high
carbohydrate, low fat, low calorie diet. They found that the low
carbohydrate group lost more weight at 3, 6 and 12 months and had lower
triglyceride levels, and improved HDL cholesterol levels ("good"
cholesterol).
A Low-Carbohydrate as Compared with a Low-Fat Diet in Severe Obesity
(Journal Abstract) Added on: 6/26/2003 Hits: 1454
From the University of Pennsylvania Medical Center and The New England
Journal of Medicine, 2003: A team of medical researchers compared the
effects of a very low carbohydrate diet with the effects of a traditional
low fat, low calorie diet among obese multi-racial men and women, some of
which had diabetes and metabolic syndrome. At the end of 6 months, the low
carbohydrate diet participants lost more weight, had greater drops in
triglyceride levels, and improved insulin sensitivity.
There are tons more.
