In The Hunger Fix, Dr. Pam Peeke uses the latest neuroscience to explain how unhealthy food and behavioral "fixes" have gotten us ensnared in a vicious cycle of overeating and addiction.

Luckily, we are all capable of rewiring, and the very same dopamine-driven system can be used to reward us for healthful, exciting, and fulfilling activities.
