The increase in the prevalence of malnutrition by excess, specifically obesity, has led to the search of new factors, which influence the development of this pathology like the perception of body weight and nutritional condition. The study was performed in students of the Nutrition and Dietetics Career of the University del Mar, with the aim to relate the perception of their corporal image with their nutritional status and fat and lean cellular compartments. Anatomical figures, proposed by Montero were used. Weight height, brachial circumference and triceps skin fold were used to determine IMC, CHM, AHM and AGB. A trend was observed to the overestimation of the nutritional condition to the fat compartment (pp<0,001).
