The high prevalence of obesity coupled with chronic inflammation and immune activation places human immunodeficiency virus (HIV)-infected individuals at increased risk for metabolic complications emphasizing the need for more aggressive management of obesity and related co-morbidities in the aging HIV-infected population. The most effective treatment for obesity and metabolic syndrome is lifestyle modification, usually with a combination of caloric restriction and increased exercise. Intermittent caloric restriction (ICR) or intermittent fasting simplifies caloric restriction by severely limiting calories only a few days per week and allowing ad lib diet on the other days. Weight loss benefits are similar to those seen with conventional diets, however, data suggests possible added health benefits from intermittent fasting. We propose to study the benefits of a 2-5 ICR strategy on weight, insulin resistance, and cardiovascular disease markers in obese HIV-infected adults with features of the metabolic syndrome. In a prospective pilot study, 50 HIVinfected adults will be randomized 1:1 to ICR or standard-of-care instruction of healthy diet and lifestyle for a 12-week intervention period. We hypothesize that ICR (2 days per week) will be an effective and acceptable diet strategy that will result in significant weight reduction, improvements in insulin sensitivity, and related metabolic parameters.
