Summary

This trial will study how eating wild blueberries may help overweight and obese people lose weight and fat. It will also measure effects on hormones, antioxidants, inflammation, blood lipids, glucose, diet, activity and blood pressure.

Who is the study for?
This trial is for overweight or obese men and women with a Body Mass Index (BMI) between 25-40. It's designed to see if wild blueberries help control appetite and support weight loss when mixed into yogurt, compared to a placebo syrup.
What is being tested?
The study tests the effects of wild blueberries on appetite regulation and weight loss over two phases: an initial phase assessing immediate impacts on hunger, glucose metabolism, and hormones; followed by an 8-week period where participants eat the yogurt daily while receiving weight loss counseling.
What are the potential side effects?
Since this trial involves consuming wild blueberries or a placebo with yogurt, side effects may be minimal but could include potential allergic reactions or gastrointestinal discomfort for those sensitive to ingredients in the products.
