Walnut Consumption in a Weight Loss Intervention: Effects on Weight Change, Satiety and Potential Mediating Factors
In Brief
A clinical study evaluating Walnut-rich weight loss diet and Standard weight loss diet for Overweight and Obesity. Completed, enrolled 100 participants across 1 site.
Detailed Summary
This study investigates whether walnuts help to promote weight loss, associated with increased meal satiety and satisfaction, in 100 overweight and obese men and women who are participating in a 6-month behavioral weight loss intervention. Participants will be randomly assigned to a walnut-enriched reduced-calorie diet or a standard reduced-calorie diet. Body weight, risk factors for cardiovascular disease, and self-reported feelings relevant to satiety and appetite will be measured at baseline and 3- and 6-month follow-up. Also, the response of gastrointestinal tract hormones following meals with or without walnuts will be measured in a subset of study participants (n=20). Results from this study will contribute to understanding the role of nuts in weight control, including further knowledge of the mechanisms, and will expand knowledge of how nuts in the diet may contribute to the prevention and management of obesity.

Timeline
Interventions
Composition of prescribed diets will be based on individual preferences, with the goal of reduced energy intake and increased energy expenditure. During the 6-month intervention, study subjects will participate in individualized counseling and group sessions, with in-person, telephone, email and text message contacts to provide support and behavioral guidance and strategies. Walnuts will be provided to participants. The overall content of the intervention consists of key elements of cognitive-behavioral therapy for obesity. The physical activity component emphasizes planned aerobic exercise, increased physical activity in the lifestyle, and strength training.
