Table 5.

Body weight, weight gain and food intake during the experiment in lean ad libitum (a.l.), obese pair fed (p.f.), and obese a.l. Zucker rats receiving diets with 8 % walnut oil (W8), 14 % walnut oil (W14) and 14 % lard (L14)

Weight gain (g/week)	W8	11.2 ± 1.3^a	16.7 ± 1.7^b	20,3 ± 1.7^c
	W14	11.0 ± 1.6^a	16.8 ± 3.4^b	20.3 ± 3.5^c
	L14	10.6 ± 1.4^a	15.3 ± 2.8^b	18.8 ± 3.6^c
Food intake (g/day)	W8	13.2 ± 0.4^a	13.2 ± 0.1^a	16.4 ± 1.2^b
	W14	12.8 ± 0.6^a	13.2 ± 0.1^a	16.3 ± 0.9^b
	L14	13.3 ± 0.3^a	13.4 ± 0.1^a	16.5 ± 0.5^b

Data are expressed as mean ± SD (n = 9–10). Values in a common row of the identical intervention labeled by different letters are significantly different between phenotypes

Significant differences within phenotypes are labeled by * (p < 0.05 compared to W8)
