Our previous studies have demonstrated the biological effects of alginic acid as a brown algae (Undasia pinnatisda) component on inhibitory action of obesity using animal model. This study was designed to investigate the effect of brown algae (BA)-noodles ($10\%,\;20\%$ and $40\%$) on inhibitory action of obesity in Sprague-Dawley (SD) male rats for 4 weeks. Body weight gain in SD rats for 4 weeks resulted in a marked inhibition ($7\%,\;17\%\;38\%$, respectively) by administration of $10\%,\;20\%$ and $40\%$ BA-noodles compared with control group. Total energy intake and feed efficiency in SD rats for 4 weeks resulted in a marked inhibition ($6\%,\;16\%\;37\%$ and $10\%\;20\%\;40\%$, respectively) by administration of $10\%\;20\%$ and $40\%$ BA-noodles compared with control group, but gross efficiency was not observed in these BA-noodle groups. Rohrer index and TM index as an obesity markers in SD rats for 4 weeks significantly decreased ($10\%\;15\%$ and $22\%$, respectively) by administration of $10\%,\;20\%$ and $40\%$ BA-noodles compared with control group. These results suggest that inhibitory effect of obesity in SD rats for 4 weeks may be due to decreases of body fat content resulted in a decrease of feed efficiency and energy intake by these BA-noodles.
