The effects of optimized slowly digestible starch (SDS) and resistant starch (RS) from rice starch on weight gain and lipid metabolism in mice (C57BL/6J mice) fed a high-fat diet were investigated. The optimum conditions for SDS were obtained at the pullulanse concentration (${\chi}_1$) of $498{\mu}L$, storage temperature) (${\chi}_2$) of $47^{\circ}C$, and A/C cycle (${\chi}_3$) of 5, and for RS, were determined to be $838{\mu}L$ (${\chi}_1$), $62^{\circ}C$ (${\chi}_2$), and a cycle of 3 (${\chi}_3$) using response surface methodology (RSM). Mice fed SDS and RS for 6 weeks showed both significantly decreased weight gain and fat pad weight (p<0.05). Significant decrease in total lipid, triglyceride, and cholesterol concentrations in serum and liver was observed in both SDS and RS group compared to HFD groups (p<0.05). Although both of intake SDS and RS significantly contributed to beneficial effects, RS groups was more effective than SDS group in all parameters.
