Brief Summary

Background: Weight gain can lead to obesity and diabetes even in people living with human immunodeficiency virus (HIV). Researchers want to see if the technique intermittent calorie restriction can help overweight people with HIV as an alternative to traditional diets. Objective: To see if intermittent calorie restriction leads to weight loss and improved blood sugar in obese people with HIV. Eligibility: Adults ages 18-65 with HIV who are obese and do not have diabetes Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Before starting treatment, participants will:

  • Have a nutritional consultation
  • Get a pedometer to record daily steps
  • Test a restricted diet for 1 day
  • Have a body x-ray At the baseline visit, participants will have:
  • Blood drawn after they drink a sugar drink
  • Questions about their health and eating
  • A nutritional consultation
  • Resting energy expenditure measured. Participants will fast overnight. Then they will lie down while a plastic bubble goes over the head and a plastic sheet covers the upper body. Oxygen flows into the bubble.
  • Liver stiffness test. A wand on the stomach releases sound waves like an ultrasound. For 12 weeks, some participants will be on a standard diet. Others will restrict how much food they eat 2 days a week. On those days they will eat about 25% of their recommended calories. Participants will keep a diary of their diet and steps. Participants will have 4 visits during the 12-week diet and 1 visit 12 weeks after the diet ends. They will repeat previous tests.

Outcome Measures

Primary Outcomes (2)

  • Change in Weight

    The effect of intermittent fasting was measured by change in weight between baseline and at week 12

    Assessed before 12-week intervention (baseline) and at week 12

  • Change in Insulin Sensitivity

    The effect of intermittent fasting on insulin sensitivity was measured by change in homeostatic model assessment of insulin resistance (HOMA-IR) between baseline and week 12. Homeostasis model assessment of insulin resistance (HOMA-IR) is a method to measure insulin sensitivity. Optimal insulin sensitivity is a HOMA-IR ratio less than 1. Levels above 1.9 signal early insulin resistance, while levels above 2.9 signal significant insulin resistance.

    Assessed before 12-week intervention (baseline) and at week 12

Secondary Outcomes (6)

  • Change in Controlled Attenuation Parameter (CAP) Score

    Assessed before 12-week intervention (baseline) and at week 12

  • Change in Visceral Adipose Tissue

    Assessed before 12-week intervention (baseline) and at week 12

  • Change in Lipid Panel Levels

    Assessed before 12-week intervention (baseline) and at week 12

  • Change in C-reactive Protein (CRP) Levels

    Assessed before 12-week intervention (baseline) and at week 12

  • Change in Beck Depression Inventory (BDI) Score

    Assessed before 12-week intervention (baseline) and at week 12

  • +1 more secondary outcomes

Study Arms (2)

Intermittent Fasting diet

EXPERIMENTAL

HIV positive subjects with body mass index ≥30 kg/m2 (obese) consume approximately 25% of their daily calories for 2 non-consecutive days per week, normal diet for the other 5 days, and receive healthy lifestyle counseling for 12 weeks.

Behavioral: Intermittent fasting

Standard of Care diet

ACTIVE COMPARATOR

HIV positive subjects with body mass index ≥30 kg/m2 (obese) receive nutritional and healthy lifestyle counseling for 12 weeks.

Other: Standard of Care

Interventions

Subject will consume approximately 25% of their daily calories for 2 days per week. The other 5 days they will eat their normal diet

Intermittent Fasting diet

Subject will receive standard of care recommendations for healthy diet and lifestyle
