Effects of HFD on basal values in anesthetized rats

	CON (n = 37)	OR (n = 35)	OP (n = 42)
MAP, mmHg	104 ± 3	104 ± 2	110 ± 2
HR, beats/min	357 ± 6	360 ± 7	368 ± 7
Body wt, g
Baseline	266 ± 2	264 ± 2	268 ± 2
4 wk HFD	438 ± 5	425 ± 5	490 ± 5*
∆	173 ± 5	161 ± 5	212 ± 3*

Values are means ± SE; n, number of rats. HFD, high-fat diet; MAP, mean arterial pressure; HR, heart rate; CON, control; OR, obesity-resistant; OP, obesity-prone. Baseline body weight was not obtained in 5 CON, 3 OR, and 5 OP rats.

^*P < 0.05 vs. CON and OR.
