What is the evidence regarding medical nutrition therapy for people with HIV infection?
Seven studies were evaluated regarding medical nutrition therapy (MNT) and/or nutrition counseling in people with HIV infection. One study, completed prior to highly active antiretroviral therapy, stressed that early intervention may prevent progressive weight loss. Four studies regarding MNT reported improved outcomes related to energy intake and/or symptoms (with or without oral nutritional supplementation) and cardiovascular risk indices, especially with increased frequency of visits. Two studies regarding nutritional counseling (non-MNT) also reported improved outcomes related to weight gain, CD4 count and quality of life
