Table 2. Body weight gain and food efficiency ratio in mice fed high fat diet with lactic acid bacteria for 6 weeks.

	ND1)	HFD	HFD + Q180
Body weight gain (g)	3.33 ± 0.51NS3)	6.12 ± 3.14	5.07 ± 1.26

All values are the mean ± SD (n=6).

¹⁾ND, normal diet; HFD, high fat diet with saline solution; HFD+Q180, high fat diet with L. plantarum Q180 (10⁹ CFU/day).

²⁾Food efficiency ratio = total body weight gain/total food intake.

^3)NSValues in a row are not significantly different at p<0.05.
