Popis: The intake of processed foods of high calorie density is associated with weight gain and changes in lipid and cardiovascular metabolism. However, the modification of eating habits is possible due to, among other factors, information provided to patients about the foods/nutrients ingested. The present investigation observed the impact of nutritional counseling on anthropometric and on biochemical indicators in a blind controlled study. Therefore, a single investigator counseled obese workers divided into three groups over a period of 42 days. A control group (CG) received no counseling. GLi50 received 60 g/d linseed and 50% of the energy supply as carbohydrates; GRi50 received 60 g/d raw ground rice and 50% of the energy supply as carbohydrates, and GLi32 received 60 g/d linseed and 32% of the energy supply as carbohydrates. A total of 118 vo- lunteers started the protocol and 52 completed it. The most consumed foods were rice, beans, bread, manioc flour, soy oil, red meat, and eggs. CG did not show any modifications. The remaining groups, regardless of diet composition, showed a reduction of anthropometric measurements, be- sides reduced glycemia, cholesterolemia, triglycerides and insulinemia, as well as reduced peripheral resistance to the action of insulin. More important than supplementation or the proportion of carbohydrates ingested, nutritional coun- seling was the common factor for adequacy of energy intake, weight loss and improved biochemical indicators. Nutrition counseling can be a viable and economically strategy for helping patients with life style diseases.
