Project « Reward mechanisms in obese patients »

In this 2-year research project, we investigate the psychological and cerebral underpinnings of food reward mechanisms in obese patients. More specifically, we investigate 2 sub-components of food reward: i) the pleasure during food consumption (liking) and ii) efforts an individual is willing to invest to be delivered with food (wanting).
We present healthy and obese participants with solutions (such as chocolate milkshakes) while their brain activity is recorded.
To do so, we use a gustometer, a device allowing the delivery of liquids in an extremely precise fashion, which is fMRI (functional Magnetic Resonance Imaging)-compatible.
We hope to better understand how food reward mechanisms differ between healthy and obese individuals, but also how they differ between obese individuals following weight loss.
