Obesity counseling should focus on neurobehavioral processes, not personal choice, researchers say
Date:7/31/2011

em, a neural pathway in the brain also known as the reward circuit. Food reward includes both the experience of pleasure one receives from eating and the motivational drive to obtain and consume highly palatable foods. Those with greater sensitivity to reward have stronger food cravings for sweet and fatty foods. This biologically-based sensitivity, coupled with easy access to delicious snacks and fast food outlets, makes one highly vulnerable to overeating and weight gain.

  • Inhibitory Control Beyond the intensity of food cravings is the ability to suppress urges to eat high-calorie foods. Controlling behavior despite a strong motivation to eat is largely mediated by the brain's prefrontal cortex, which is considered critical for self-control, planning and goal-directed behavior. The dorsolateral region of the prefrontal cortex has been implicated in the decision to engage inhibitory processes for the purpose of self-regulation, and this brain area becomes activated when dieters choose healthy food options over tastier options.

  • Time Discounting A third factor that likely contributes to the low success rates of dietary interventions for obesity is the human tendency to devalue delayed rewards.

    "Most of us would rather receive $200 today rather than $300 a year from now," said Appelhans.

    Similarly, the immediate pleasure from eating has a greater effect on decision making than the more delayed health benefits of weight loss.

    The link between time discounting and body weight is reflected neuroanatomically because it is governed by the same brain regions associated with food reward and inhibitory control the mesolimbic dopamine system and the prefrontal cortex.

    "Obesity is heavily influenced by genetic vulnerabilities and a toxic food environment," said Appelhans. "However, counselors can help patients control their weight through strategies focused on the interaction between the brain and th
