Ghrelin stimulates food intake in rats fed a high-fat diet.

Group-diet Type	Saline or Ghrelin Challenge	Food Intake (kcal/rat)
AIN-76A	Saline	2.3 ± 0.51
	Ghrelin	4.6 ± 0.5*
High-fat	Saline	8.5 ± 1.2†
	Ghrelin	12.2 ± 1.0*†

1 = mean food intake ± SEM; N = 8–12 rats/group,

^*p<0.05 vs. saline.

^†p<0.05 vs. respective group of AIN-76A fed rats.
