One hundred overweight and obese participants were randomly assigned to the standard diet or the walnut-enriched diet in the context of a behavioral weight loss intervention (walnuts provided approximately 15% of total energy intake). During the clinic visits, at the beginning and after 3 and 6 months, body measurements, blood pressure, physical activity, lipids, tocopherols (antioxidants) and fatty acids were obtained.
The study observed that both study groups reduced body weight, body mass index and waist circumference. Also systolic blood pressure decreased in both groups at 3 months, but only the walnut-enriched diet group maintained a lower systolic blood pressure at 6 months. On the other hand, the walnut-enriched diet group reduced total cholesterol and LDL (“bad”) cholesterol at 6 months.
The study concluded that a walnut-enriched reduced-energy diet may promote weight loss. Although weight loss was associated with improvements in cardiovascular disease risk factors, the walnut-enriched diet promoted more favorable effects on LDL cholesterol and systolic blood pressure.
