Glutamine-based treatment in the prevention study does not decrease weight gain but improves serum lipid metabolism in mice with diet-induced obesity. a Experimental design of the prevention study. b Curve of body weight changes (n = 10). c Body weights before euthanizing the mice (n = 10). d Body composition (n = 10). e Food intake (n = 6 to 8). f Water intake (n = 7 to 8). g Rectal temperature (n = 10); h Serum TG levels (n = 10). i Serum CHOL (n = 10). j Serum HDL (n = 10). k Serum LDL (n = 10). l Serum urea (n = 10). m Serum AST (n = 10). n Serum ALT (n = 10). o Serum Gln (n = 10). Values are shown as the mean ± SEM. * Significantly different from the SD group. # Significantly different from the HFD group. Significance: * or #, p < 0.05; ** or ##, p < 0.01; *** or ###, p < 0.001. TG, triglycerides; CHOL, cholesterol; HDL, high-density lipoprotein; LDL, low-density lipoprotein
