Weight gain increased strikingly in rats with extended access to the cafeteria diet compared to the chow-only or restricted access groups (Fig. 1a).

The development of obesity in extended access rats was closely associated with a worsening deficit in brain reward function, reflected in progressively elevated BSR thresholds
