The nutritional pattern is linked to changes in the prevalence of overweight (OW) and obesity (OB), which are risk factors for insulin resistance (IR). However, this link varies from population to population. There are no studies on the population of the Capital City of San Luis, Argentina, on the possible link between nutritional pattern, nutritional status and IR. Our central hypothesis is that changes in nutritional habits determines changes in the prevalence of OW / OB and therefore changes in the incidence of IR in this population. To test this hypothesis we conducted a quantitative, observational, transversal and descriptive study in a sample of 78 patients including men (n=40) and women (n=38) between 18 and 80 years living in the central neighborhoods of the city of San Luis between 2015-2017. Of these patients nutritional data were obtained through an standardized food-frequency questionnaire, anthropometric measurements (weight, height and waist circumference) and a blood sample for biochemical analysis. These data allowed us to relate the nutritional pattern, nutritional status and IR. The total population was composed of 22% OW and 9% Type 1-OB according their body mass index (Kg / m2). Analysis of the nutritional pattern showed that the studied population consumes: 14% of the group of grains and legumes, 18% fruits and vegetables, 8% meat and eggs, 7% milk, 1% oil seeds and nuts and 17% sweets and fats. Water consumption was 30% of the average consumption. Waist circumference (cm)?a marker of central obesity was greater in 37% and 17% of women and men, respectively, thus those have an increased metabolic risk. Of all patients surveyed baseline glycemia (mg / dL) was normal in 90%, while 6% was hypoglycemic. 4% of the total population showed cholesterol concentration at the upper limit (i.e., close to 200 mg/dL). The HDL-c was reduced (
