S.D.M Protocol

The VLCKD approach

The S.D.M. diet is based on a medical dietetic protocol called VLCKD (Very Low Calorie Ketogenic Diet) , studied by Prof. Blackburn of Harvard University in 1971.

It is a normoproteic protocol, with a daily intake of protein equivalent to the physiological requirements. It is also a low-calories regime due to the reduced introduction of carbohydrates and lipids. It is a dietetic therapy aimed to achieve rapid weight loss through three stages: weight loss, transition and maintenance.

Over time, the effectiveness of the protocol favored its spread worldwide becoming a reference diet for many specialists who deal with overweight and obesity.


The protocol includes three basic phases: A first phase of real slimming, a second transition phase, which consists in the gradual reintroduction of foods mostly with carbohydrate content, and a third maintenance phase, aimed at achieving a balanced diet.

stages of the diet

Professor Blackburn, of Harvard University, defines the first protocol of the Protein Diet. He calls this study PSMF or Protein Sparing Modified Fasting.


Professor Marineau translates the tag PSMF with the expression "Jeune proteiné", in English Fast Protein. In fact, It was essentially a clearer distinction between the Blackburn method and the high-protein diets like the Atkins one. During the following years the diet got positive feedback: the spread of the Protein Diet method began and millions of patients were successfully treated.


The Protein Diet acquires validation of the Protocol by the US Department of Health.


Professor Bjorntorp deepens the study of the protocol and publishes the result of his researches on Lancet Magazine.


From 2003 to 2010, the Protein Diet (VLCKD) starts to be suggested by the Finnish Ministry as the first intention therapy to be introduced in the program for the prevention of obesity associated with risk factors such as type 2 diabetes , glucose intolerance, dyslipidemia and hypertension.


The Italian Association of Dietetics and Clinical Nutrition (ADI) states that "the ketogenic diet can be considered as an interesting alternative to other treatments especially when a rapid weight loss is required , since it helps to contain the global risk of health and patients' motivation".(1)
