A total of 100 participants were enrolled and assigned to a 4-month behavioral weight loss intervention (control group) or also prescribed 1.5 oz/day (42 g/day) of pistachios (pistachio group). Participants in the control group were requested to abstain from consuming nuts during the study. Weight, height and waist circumference were measured, and a blood sample was collected at each scheduled clinic visit. The cardiopulmonary fitness of the participants was also assessed. Detailed dietary data were collected from all study participants and physical activity was estimated with a validated questionnaire. Prior to the visit, participants were mailed questionnaires to be completed and brought to the visit.
Researchers observed that regular pistachio consumption was associated with weight loss, and similar reductions in body mass index (BMI) and waist circumference, in overweight/obese adults compared to the control group, and favorable changes in the diet were observed.
In conclusion, pistachios may contribute to a healthy dietary pattern and weight reduction in the context of an energy-restricted diet in a behavioral intervention, and may confer additional health benefits such as a reduction of blood pressure. Additionally, regular pistachio consumption has been associated with healthful shifts in dietary intake and food choices.
