Metabolic Health, Bones and Nuts During Weight Loss in Adults

This study is looking at how eating peanuts might affect bone health and overall metabolic health (like blood sugar and fats) during weight loss in older adults. Researchers want to see if a daily peanut snack, compared to a nut-free snack, can help improve bone mineral density (BMD) in the hip. You could be eligible if you are between 50 and 75 years old, are a man or a postmenopausal woman, and have a Body Mass Index (BMI) between 25 and 42 (indicating overweight or obesity). The study plans to enroll 44 participants, but its current status is unclear.

Study design: This is an interventional study that aims to enroll 44 participants. You would be randomly assigned to either receive a daily peanut snack or a nut-free snack.
What's involved: You would need to attend about 10 on-site visits in New Brunswick, NJ, USA, over 24 weeks. You would also receive nutrition education and behavior modification instructions for weight loss.
Compensation: Reimbursement for travel is not included.
Follow-up: Your bone mineral density (BMD) in the hip will be measured at 24 weeks from the start of the study.
