Introduction: The Calorie Restriction (CR) model aims to reduce the total calories eaten per week. The two most common ways to achieve the desired caloric deficit (% CR) are to reduce intake every day or to establish intermittent fasting or severe restriction days, where the impact of the restriction is more important, has less impact on the loss of mass muscle, and adherence to the diet model is more facilitated. It is proposed to work on a CR model close to 40% of the normal caloric content, intercalating 3 days of severe restriction (600-800Kcal) per week with the rest of habitual intake, over a period of 6 weeks.

Content of the research: Eighteen healthy and physically active subjects followed a caloric restriction pattern (34.3 ± 15.4%) for 6 weeks, in which they maintained their regular physical activity. At the beginning and at the end of the experiment the body composition by densitometry was determined and the weight loss and its distribution in the different tissues were quantified. The consequences of diet were also evaluated in hematological and biochemical parameters.

Conclusions: A considerable weight loss is achieved, mainly at the expense of the fat mass (predominantly
