Schematic representation of the intermittent, extended access to a palatable diet procedure used in this study. Briefly, subjects were divided in two groups: a first group received a regula chow diet ad libitum daily (Chow/Chow), and a second group received two days of chow diet followed by a day of a highly palatable, chocolate flavored, high-sugary, diet (Chow/Palatable). For brevity, the first 2 days (chow only) and last day (chow or palatable per diet condition) of each cycle are referred to as C and P phases.
