Evolution in body weight gain for sham and abdominal vagal stimulated groups (top left panel). Note that body weight relative to the pre-operative one was significantly reduced in the stimulated group after 45 days of continuous stimulation. This reduction was a consequence of both a diminished daily food intake (top right panel) and an increased resting energy expenditure (bottom right panel). The decreased body weight in the stimulated group was representative of a reduced visceral fat (bottom left panel)
