d-Allulose supplementation normalized the body weight and fat-pad mass in diet-induced obese mice via the regulation of lipid metabolism under isocaloric fed condition

A number of findings suggest that zero-calorie d-allulose, also known as d-psicose, has beneficial effects on obesity-related metabolic disturbances. However, it is unclear whether d-allulose can normalize the metabolic status of diet-induced obesity without having an impact on the energy density. We investigated whether 5% d-allulose supplementation in a high fat diet(HFD) could normalize body fat in a diet-induced obesity animal model under isocaloric pair-fed conditions.
Methods and results
Mice were fed an HFD with or without various sugar substitutes (d-glucose, d-fructose, erytritol, or d-allulose, n = 10 per group) for 16 wk. Body weight and fat-pad mass in the d-allulose group were dramatically lowered to that of the normal group with a simultaneous decrease in plasma leptin and resistin concentrations. d-allulose lowered plasma and hepatic lipids while elevating fecal lipids with a decrease in mRNA expression of CD36, ApoB48, FATP4, in the small intestine in mice. In the liver, activities of both fatty acid synthase and β-oxidation were downregulated by d-allulose to that of the normal group; however, in WAT, fatty acid synthase was decreased while β-oxidation activity was enhanced.
Taken together, our findings suggest that 5% dietary d-allulose led to the normalization of the metabolic status of diet-induced obesity by altering lipid-regulating enzyme activities and their gene-expression level along with fecal lipids.
