Low-Carbohydrate Diets More Successful Than Standard Dieting



  • Intermittent, low-carbohydrate diets were superior in lowering blood levels of insulin, which can lead to cancer.
  • Low-carbohydrate diet two days per week resulted in greater weight loss than standard daily dieting.
SAN ANTONIO — An intermittent, low-carbohydrate diet was superior to a standard, daily calorie-restricted diet for reducing weight and lowering blood levels of insulin, a cancer-promoting hormone, according to recent findings.

Researchers at Genesis Prevention Center at University Hospital in South Manchester, England, found that restricting carbohydrates two days per week may be a better dietary approach than a standard, daily calorie-restricted diet for preventing breast cancer and other diseases, but they said further study is needed.

“Weight loss and reduced insulin levels are required for breast cancer prevention, but [these levels] are difficult to achieve and maintain with conventional dietary approaches,” said Michelle Harvie, Ph.D., SRD, a research dietician at the Genesis Prevention Center, who presented the findings at the 2011 CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 6-10, 2011.

Harvie and her colleagues compared three diets during four months for effects on weight loss and blood markers of breast cancer risk among 115 women with a family history of breast cancer. They randomly assigned patients to one of the following diets: a calorie-restricted, low-carbohydrate diet for two days per week; an “ad lib” low-carbohydrate diet in which patients were permitted to eat unlimited protein and healthy fats, such as lean meats, olives and nuts, also for two days per week; and a standard, calorie-restricted daily Mediterranean diet for seven days per week.

Data revealed that both intermittent, low-carbohydrate diets were superior to the standard, daily Mediterranean diet in reducing weight, body fat and insulin resistance. Mean reduction in weight and body fat was roughly 4 kilograms (about 9 pounds) with the intermittent approaches compared with 2.4 kilograms (about 5 pounds) with the standard dietary approach. Insulin resistance reduced by 22 percent with the restricted low-carbohydrate diet and by 14 percent with the “ad lib” low-carbohydrate diet compared with 4 percent with the standard Mediterranean diet.

“It is interesting that the diet that only restricts carbohydrates but allows protein and fats is as effective as the calorie-restricted, low-carbohydrate diet,” Harvie said.

Dietitians Are Buying Coke’s Line: Sugar, Fluoride, Artificial Colors are SAFE for Children!


The credentialing arm of the American Dietetic Association, the Commission on Dietetic Registration (CDR), has approved a program created by the The Coca-Cola Company Beverage Institute for Health and Wellness.This covers what it calls “urban myths” about the safety of food ingredients. Participating in this program will earn registered dietitians Continuing Professional Education unit credits.

“Children’s Dietary Recommendations: When Urban Myths, Opinions, Parental Perceptions & Evidence Collide,” tells dietitians that fluoride, sugar, artificial colors and nonnutritive sweeteners have been “carefully examined for their effects on children’s health, growth, and development.” The presenter, Dr. Ronald Kleinman, “explores prevalent misconceptions about these food ingredients” and suggests ways the dietitian can help quell unnecessary “concern among parents about their children’s health.”

At first glance, Dr. Kleinman should know what he is talking about. He is physician-in-chief at Massachusetts General Hospital for Children, chief of the Pediatric Gastrointestinal and Nutrition Unit, and Associate Professor of Pediatrics at Harvard Medical School. Couldn’t sound better, could it? But he has also received a great deal of money from industry sources—like artificial infant formula manufacturers Mead Johnson and Nestle Ltd. His study on optimal duration of breastfeeding was funded by Gerber Products. He also served as a paid expert witness for Gerber when they were sued for deceptive advertising. And he contributed to a brochure intended for children entitled “Variety’s Mountain” produced by the Sugar Association.

Now he’s being sponsored by the Coca-Cola Company and telling dietitians that the ingredients in Coke which everyone is alarmed about are safe. The dietitians, in turn, will be telling parents that their fears are unfounded, and Coke can sell more Coke to kids.

Program materials include gems like “[a] majority of studies so far have not found a link between sugar and behavior in children generally or children diagnosed with attention deficit hyperactivity disorder.” This is certainly news to us, since we have seen many studies that say the opposite. Apparently the dietitians are to teach us that any connection between artificial colors and neurotoxicity, or fears of the dangers of fluoride, are imaginary and come from hysterical (or at least unduly concerned) parents.

As we reported recently, sugar and artificial sweeteners are anything but safe. Fluoride poses a significant risk to the kidneys. And commonly used food dyes pose risks which include hyperactivity in children, cancer (in animal studies), and allergic reactions. Even the Center for Science in the Public Interest, an organization that supports nuking food, agrees with this. And the British government and European Union have taken actions that are virtually ending the use of dyes throughout Europe.

The ADA is sponsored by the soda and junk food industries—which we feel greatly tarnishes the organization’s credibility. And you may recall that the ADA has mounted a state-by-state campaign to make sure that its Commission is the only one which will be accepted as a credentialing body for both registered dietitians and nutritionists.

There are, of course, significant philosophical differences between nutritionists and dietitians—they represent two different fields of study and practice. By accepting only a single credentialing agency—one run by the dietitians, not nutritionists—state boards are establishing a “one-size-fits-all” standard which removes all competition, essentially handing the ADA a government mandated monopoly over nutritional therapy.

Unfortunately, the Nevada bill we told you about last month passed both the Assembly and the Senate and was signed by the governor on June 5th. While some amendments were made, the most troubling parts of the bill still remain: only registered dietitians can practice “dietetics,” which is defined by the law to include nutrition assessment, evaluation, diagnosis, counseling, intervention, monitoring and treatment—everything that a good nutritionist does and should do.

We also told you about an ADA bill in New York, S.3556. The state’s Senate Finance Committee met on June 13 and decided to pass the bill to the Rules Committee so that it could be considered on the Senate floor. They are trying to rush these bills through, because next week the Assembly is scheduled to finish its work for the year, unless the chair calls a special session in the fall. Please click on our New York Action Alert here.

The ADA’s power grab is a complete travesty. We will keep fighting it state by state until we restore competition in nutritional counseling and stop gagging PhD-trained nutritionists who don’t become dietitians.
