Dr. Bernstein Urges Look at a Spanish Study That Bolsters the Case for Low-Carb Diets

Our Advisory Board Member Dr. Richard K. Bernstein has courageously championed the low carb diet for 20 years despite the fact that many people thought he was “out to lunch.” Although his patients loved him for helping them control their high BGs and reverse their complications, other medical professionals often criticized his low carb methods.

Recently, Dr. Bernstein alerted Diabetes Health to a 2007 Spanish university study that reaches the same conclusions Dr. Bernstein did 20 years ago.

The study, “Arguments in Favor of Ketogenic Diets” by Joaquín Pérez-Guisado, PhD, a doctor on the medical faculty at the University of Córdoba, was first published in The Internet Journal of Nutrition and Wellness in 2007.

In his abstract, Dr. Pérez-Guisado disputes the current wisdom that the best way to lose weight is by cutting back on calories, chiefly those from fat. Instead, he contends that:

  • Low-carb diets are a much more effective way to lose weight.
  • Such diets preserve muscle mass, reduce appetite and induce thermogenesis (the burning of fat).
  • They promote a non-atherogenic lipid profile (atherogenesis is the build-up of lipid-containing plaques on arterial walls), lower blood pressure and decrease insulin resistance.
  • They should be used to prevent or treat type 2 diabetes and cardiovascular problems.
  • Such diets, although they induce ketosis, do not harm or endanger kidney, liver or heart functions.

None of Dr. Pérez-Guisado’s assertions is new. His extensively footnoted study—there are 181 citations that make up about half of the paper—is a summary of conclusions reached by other scientists and researchers. “Arguments in Favor of Ketogenic Diets” is a compilation of low-carb diet data that will probably become a staple reference for low-carb advocates as the debate over diets continues.
