This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand how different types of snacks affect your brain's response to food and your feeling of fullness during a diet. You'll spend 12 weeks on a weight-loss program and eat either walnuts or pretzels as your daily snack—whichever group you're randomly assigned to. The study team will use brain imaging to see if the type of snack you eat changes how your brain reacts to food.
Many people struggle with hunger and cravings while dieting, and researchers think the type of snack you choose might make a real difference in how satisfied you feel. This study will help scientists understand whether certain snacks are better at controlling appetite from a brain perspective.

Over 12 weeks, you'll follow a reduced-calorie diet and eat the snack assigned to your group (walnuts or pretzels) every day. You'll meet with study staff weekly—some meetings will be virtual, and you'll have in-person visits every 2–3 weeks. You'll also have brain imaging scans at certain points to let researchers see how your brain is responding to food during the diet.
