In order to better understand how commonly used dietary interventions for obesity influence brain activity and in turn people's ability to adhere to their healthy nutrition plan, the investigators need to study how people's brains react to food cues while undergoing such interventions. Our study will add to our understanding of neural (brain) regulation of hedonic and homeostatic mechanisms (i.e. pleasure and hunger) in influencing adherence to calorie-reduced eating plans.
