In our colony, yellow obese mice were longer than nonobese littermates and yellow males were heavier than yellow females. Weight gain was greatest on high fat diets. If the yellow mice were given a possibility to exercise (activity cages), they lost weight. Resistance to cold was good. Fasted blood glucose levels were normal, fed levels frequently elevated in males. Yellow male and female mice showed a degree of insulin resistance; yellow males showed a marked hyperglycemic response to growth hormone, ACTH, cortisone, and glucagon. Blood total lipids were elevated in yellow mice, with the females exhibiting hypercholesterolemia. As in other forms of ‘metabolic’ obesity, blood ketones were decreased by an 18 hours fast.

Quercetin is a flavonoid that has been shown to have health-promoting capacities due to its potent antioxidant activity. However, the effect of chronic intake of quercetin on the gut microbiome and diabetes-related biomarkers remains unclear. Male C57BL/6J mice were fed HF or HF supplemented with 0.05% quercetin (HFQ) for 6 weeks. Diabetes-related biomarkers in blood were determined in mice fed high-fat (HF) diets supplemented with quercetin. Mice fed the HFQ diet gained less body, liver, and adipose weight, while liver lipid and blood glucose levels were also lowered. Diabetes-related plasma biomarkers insulin, leptin, resistin, and glucagon were significantly reduced by quercetin supplementation. In feces, quercetin supplementation significantly increased the relative abundance of Akkermansia and decreased the Firmicutes/Bacteroidetes ratio. The expression of genes Srebf1, Ppara, Cyp51, Scd1, and Fasn was downregulated by quercetin supplementation. These results indicated that diabetes biomarkers are associated with early metabolic changes accompanying obesity, and quercetin may ameliorate insulin resistance.

Abstract Indian gooseberry (Phyllanthus emblica L.) is widely used in Ayurvedic medicine, traditional Chinese medicine, as well as traditional medicine to treat health complications including disorders of diabetes and obesity. The aim of this study was to investigate the effects of Indian gooseberry fruit on anxiety-related behaviors and memory performance in high-fat diet-induced obese mice. C57BL/6 mice were randomly divided into four groups (n = 11 pre group); group 1: normal diet control, 2: normal diet treated with Indian gooseberry fruit juice, 3: high-fat diet control, and 4: high-fat diet treated with Indian gooseberry fruit juice. Each mouse was orally and daily administrated with 5mL/kg of Indian gooseberry fruit juice. After six weeks, all groups were tested for blood glucose levels, anxiety and memory performances, and the level of interleukin 6 (IL-6) in the hippocampus. The results revealed that the treatment with Indian gooseberry juice for six weeks produced a significant decrease in blood glucose levels (P <0.05). In anxiety-related behaviors, Indian gooseberry juice showed a remarkable decrease in self-grooming behavior (P <0.001). In addition, there was a significant increase in memory performance in the high-fat diet treated with Indian gooseberry fruit juice compared to the high-fat diet control (P <0.05). Furthermore, the level of inflammatory cytokine IL-6 in the hippocampus was significantly decreased after oral administration of Indian gooseberry fruit juice (P <0.05). These findings suggest that Indian gooseberry fruit can serve as a natural nutritional treatment for preventing high-fat diet-induced cognitive impairment.

Adipose tissue metabolism in vitro was studied, after substitution for several weeks of synthetic low-carbohydrate, high-fat (saturated or unsaturated) diets for the standard chow diet, in obese hyperglycemic mice and in their nonobese littermates. In tissue from nonobese mice fed the high-fat diets, glucose metabolism to CO2 and to fatty acids was diminished in the absence of added hormone, while glucose carbon incorporation to glyceride-glycerol was increased. Under insulin (0.1 unit/ml) stimulation, total glucose uptake was relatively decreased by the diets, as was glucose metabolism to CO2, to fatty acids, and to glycogen; however, glucose carbon incorporation to glyceride-glycerol was unaltered. Under epinephrine stimulation, the sum of glucose carbon recovery was less after high-fat feeding. No effect of high-fat feeding was detected on base-line rates of free fatty acid release nor on the effects of insulin or epinephrine on this process. No differences were found between the effects of saturated- or unsaturated-fat diets on any parameters. The metabolism of adipose tissue from obese mice was slightly, if at all, affected by high-fat feeding. These results are discussed in reference to the normal adaptation to low-carbohydrate, high-fat diets and to the metabolic abnormalities present in obese hyperglycemic mice.

On choline-free diets containing 10, 18, and 28% casein, the total liver lipids of ducklings were found to be 34.8, 25.0, and 13.8% respectively. Supplementation of the 10% casein diet with 0.5% methionine increased the liver lipids. The same amino acid has no effect at the intermediate level of casein while it is lipotropic at the 28% casein level. In similar experiments with a purified soybean protein (low in methionine) fed at levels of 12, 21.7, and 27.9%, the liver lipids were 31.8, 26.6, and 27.6% respectively. These values do not differ significantly from each other. Methionine was found to be lipotropic at any of these three levels of soybean protein, and more so as the level of the soybean protein increased in the diet. From these results, it is concluded that the purified soybean protein used is a nonlipotropic protein, while casein is definitely lipotropic in ducklings. The lipotropic activity of methionine is closely related to the quality and quantity of the protein in the diet. On high fat diets containing 22, 32, and 42% fat, choline had no lipotropic effect. The average liver lipids for all groups ranged from 11 to 15%. High fat diets are less inducive of fatty livers than high carbohydrate diets. Ducklings fed a fat-free, choline-free basal diet presented livers with an average total lipids of 18%. Supplementing the basal diet with 1% cholesterol increased the liver lipids to 22%. Inositol is lipotropic either in the presence or absence of cholesterol, but choline was much more effective under similar conditions. The two lipotropic factors have a synergistic action and the reduction of the liver lipids is primarily on the glyceride fraction. Cholesteryl ester was at its lowest value in the group fed the basal diet supplemented with inositol only.

Abstract Background: Excessive consumption of high-fat diets is associated with disordered metabolic responses, which may lead to chronic diseases. High-fat diets containing different types of fatty acids lead to distinct alterations in metabolic responses of gut-brain axis. Methods: In our study, normal male C57BL/6J mice were fed to multiple high fatty acid diets (long-chain and medium-chain saturated fatty acid, LCSFA and MCSFA group; n-3 and n-6 polyunsaturated fatty acid, n-3 and n-6 PUFA group; monounsaturated fatty acid, MUFA group; trans fatty acid, TFA group) and a basic diet (control, CON group) for 19 weeks. To investigate the effects of high-fat diets on metabolic responses of gut-brain axis in obese mice, blood lipids were detected by fast gas chromatography, and related proteins in brain and intestine were detected using Western blotting, ELISA, and immunochemistry analysis. Results: All high-fat diets regardless of their fatty acid composition induced obesity, lipid disorders, intestinal barrier dysfunction, and changes in gut-brain axis related factors except basal diet in mice. For example, the protein expression of zonula occludens-1 (ZO-1) in ileum in the n-3 PUFA group was higher than those in the MCSFA and CON group (all Ps < 0.05). The expressions of insulin in hippocampus and leptin in ileum in the MCSFA group were all higher than those in other groups (all Ps < 0.05). Conclusions: The high MCSFA diet had the most effect on metabolic disorders, and the high n-3 PUFA diet had the least effect on changes in metabolism.
