Table 2. Effect of fasting during 48-h on body weight gain, plasma glucose, insulin and triglycerides levels and somatic indices.

	Body weight gain (g)	Glucose (mg/dl)	Insulin (ng/ml)	Triglycerides (mg/dl)	Somatic index. Liver (g/100 g BW)	Somatic index. Epididymal (g/100 g BW)	Somatic index. Visceral (g/100 g BW)
Fed	41.2 ± 2.5	120 ± 1.5	2.3 ± 0.3	162 ± 13	3.7 ± 0.1	0.96 ± 0.05	0.68 ± 0.04
Fast	11.6 ± 4.4*	91 ± 1.1*	0.44 ± 0.07*	68 ± 4.7*	2.6 ± 0.08*	0.88 ± 0.05	0.49 ± 0.05*

Values are expressed as mean ± SEM. *P < 0.05 vs. fed, t-test, n = 6. Somatic index was calculated as the ratio between tissues weight and body weight and was expressed as g/100 g body weight (BW).
