As a strategy for the prevention of symptoms and control of signals in patients with the Human Immunodeficiency Virus (HIV), the nutritional monitoring features a supporting role to drug treatment. This study aimed to report the clinical case of an HIV-1 carrier with the evaluation of nutritional counseling. A decrease in anthropometric measurements was observed (17.2% in weight, 11% in waist circumference, and 11% in arm circumference). The replacement of foods that are source of simple sugars with fruits and vegetables, decreased intake of carbohydrates in 31.7%, control of liver enzymes (glutamic oxaloacetic transaminase and glutamic pyruvic transaminase), and bilirubin balance has led to the disappearance of scleral conjunctiva jaundice. Frequency to consultations and maintenance of medications (antiretroviral therapy) were also observed. These results reinforce the importance of a nutritional approach in the treatment of Aids.
