Have a laugh at the Journal of the American College of Nutrition
O.k. In our Low-Carb Studies section, we have placed a request for any links to research proving low-carb diets to be unhealthy.
Well, a user sent me a very patronizing email, cannot quote it since I don't have his/her permission. They essentially said all you need is to use a search engine! and supplied this link:
Fad diets may do more harm than good, UK study finds
The study results were published in last monthıs Journal of the American College of Nutrition.
Many Americans are losing weight on so-called ³fad² diets ~ but in the process, they could be putting themselves at greater risk for developing coronary heart disease, according to a University of Kentucky College of Medicine study published in the October issue of the Journal of the American College of Nutrition.
A team of researchers led by James W. Anderson, professor of medicine and clinical nutrition in the UK College of Medicine, performed a critical review and computer analysis of eight popular weight-loss diets. He was joined by David Jenkins, professor of medicine and clinical nutrition at the University of Toronto, and Elizabeth Konz, a doctoral candidate in nutrition at UK.
Eight weight loss diets were analyzed in the UK study: Sugar Busters!, Protein Power, The Zone and Dr. Atkinsı New Diet Revolution were compared with moderate diets, Dr. Andersonıs High-Fiber Fitness Plan and the American Diabetes Association/American Dietetic Association Exchange Diet. The other two analyzed, the Pritikin Diet and the Ornish Diet, are on the opposite extreme of many of the popular diets, stressing a very low fat, high carbohydrate, vegetarian diet.
The researchers found that Protein Power and Dr. Atkinsı New Diet Revolution had negative effects --raising cholesterol levels, which have been linked with an increased risk for coronary heart disease.
The Atkins and Protein Power diets were found to be the highest in total and saturated fat compared to dietary guidelines. Long-term use of the diets likely would increase significantly serum cholesterol concentrations and risk for coronary heart disease, Anderson said.
³Of course, weight loss contributes to the lowering of cholesterol, but high-fat diets such as the Atkins diet increase the risk for heart attacks and strokes by raising LDL cholesterol -- the bad stuff -- and increasing the tendency for blood to form clots, which are the forerunners of most heart attacks and strokes,² Anderson said.
The protein content of four of the diets (Sugar Busters!, Protein Power, The Zone and Dr. Atkinsı New Diet Revolution) is almost double the recommended daily allowances. High animal protein intakes have been linked to higher risks for coronary heart disease. This high protein load may lead to kidney damage, especially in people with diabetes or those who have high blood pressure, Anderson said.
Sugar Busters! and The Zone diets werenıt found to cause any harm, but the researchers also did not find any evidence supporting the dietsı health claims.
³Overall, the best diet for general health promotion, weight loss and weight maintenance is a high-carbohydrate, high-fiber diet that is low in fat,² Anderson said.
Now, reading this, I though wow! How could I have missed this! A study on "patients" proving Atkins and PP raise bad cholestrol.
So, I did a search for the original study this article is quoting, and here's what the "study" is about
Health Advantages and Disadvantages of Weight-Reducing Diets: A Computer Analysis and Critical Review

Background: Some weight-loss diets are nutritionally sound and consistent with recommendations for healthy eating while others are "fad" diets encouraging irrational and, sometimes, unsafe practices.
Objective: The purpose of the study was to compare several weight loss diets and assess their potential long-term effects.
Design: Eight popular weight-loss diets were selected (Atkins, Protein Power, Sugar Busters, Zone, ADA Exchange, High-Fiber Fitness, Pritikin and Ornish) to be non-clinically analyzed by means of a computer to predict their relative benefits/ potential harm. A summary description, menu plan and recommended snacks were developed for each diet. The nutrient composition of each diet was determined using computer software, and a Food Pyramid Score was calculated to compare diets. The Mensink, Hegsted and other formulae were applied to estimate coronary heart disease risk factors.
Results: Higher fat diets are higher in saturated fats and cholesterol than current dietary guidelines and their long-term use would increase serum cholesterol levels and risk for CHD. Diets restricted in sugar intake would lower serum cholesterol levels and long-term risk for CHD; however, higher carbohydrate, higher fiber, lower fat diets would have the greatest effect in decreasing serum cholesterol concentrations and risk of CHD.
Conclusions: While high fat diets may promote short-term weight loss, the potential hazards for worsening risk for progression of atherosclerosis override the short-term benefits. Individuals derive the greatest health benefits from diets low in saturated fat and high in carbohydrate and fiber; these increase sensitivity to insulin and lower risk for CHD.
I made in bold the key points. But to emphasize it, here's what they did:
No patients (that's why they said non-clinical) were involved, just computer software that was programmed
to give results. i.e. the computer is told:
If the fat intake is above 50%, output an increase in cholestrol
If diet is low-fat, make results really good
It is a computer software based on nutritionists "recommendations".
Unfortunately, the public will be fooled by it, just as Ms. Vikki Franklin (writing for the University of Kentucky) was fooled, or tried to fool the public. The report/article she wrote, made no mention of this computer software that "simulated" the results, and talked about it is if they were actual results!
Sadly, this fraud works. And since the medical community and nutritionists cannot find any scientific bases for their calims against low-carbing, they just had to fake the results.
