Allitol is a rare sugar alcohol obtained by reducing d-allulose (d-psicose). However, information on the effects of long-term dietary allitol intake is limited. This study aimed to investigate the effect of allitol supplementation, as a sugar substitute, on body fat accumulation in rats compared with sucrose, rare sugar d-allulose, or erythritol. Thirty-two male Wistar rats (3 wk old) were fed experimental diets including 5% sucrose, allitol, erythritol, or d-allulose for 8 wk ad libitum. Weight gain, food intake, and food efficiency did not differ among the groups. The total body fat mass and percentage, and intra-abdominal adipose tissue weights were significantly lower in rats fed with the allitol diet than in those fed with the sucrose diet. These body fat indicators tended to be lower in rats fed with the erythritol and d-allulose diets than in those fed with the sucrose diet, but there was no significant difference. The serum glucose-lowering effect obtained in rats fed with the d-allulose diet did not appear in rats fed with the allitol diet. These results suggest that the anti-obesity effect of allitol may be equal to or greater than that of d-allulose.
