Weight gain and serum hormonal parameters in different mouse groups after 14 weeks of dietary intervention.

Experimental groups	Body weight gain (%)	Insulin (ng/ml)	Leptin (ng/ml)
SD group	35.03 ± 4.02	0.47 ± 0.04	9.29 ± 0.37
HFD group	62.30 ± 4.39*	2.09 ± 0.29*	36.53 ± 2.70*
HFD+Bif group	44.00 ± 2.66#	1.05 ± 0.21*#	29.78 ± 2.57*#

SD group: control mice receiving a standard diet; HFD group: obese mice receiving a high-fat diet; HFD+Bif group: obese mice receiving HFD and a daily dose of 1 x 10⁹ CFU B. pseudocatenulatum CECT 7765 by gavage during 14 weeks. Data are expressed as mean ± standard error of the mean of each mouse group (n = 10 per group).

Significant differences were established by ANOVA and post hoc Bonferroni's test at *p<0.05 versus SD group and ^# p<0.05 versus HFD group.
