Amomum tsao-ko Crevost et Lemaire (Zingiberaceae) is a medicinal herb found in Southeast Asia that is used for the treatment of malaria, abdominal pain, dyspepsia, etc. The aim of this study was to investigate the effect of an ethanol extract of Amomum tsao-ko (EAT) on obesity and hyperlipidemia in C57BL/6 mice fed a high-carbohydrate diet (HCD). First, the mice were divided into five groups (n = 6/group) as follows: normal diet, HCD, and HCD+EAT (100, 200, and 400 mg/kg/day), which were orally administered with EAT daily for 84 days. Using microcomputed tomography (micro-CT) analysis, we found that EAT inhibited not only body-weight gain, but also visceral fat and subcutaneous fat accumulation. Histological analysis confirmed that EAT decreased the size of fat tissues. EAT consistently improved various indices, including plasma levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein, high-density lipoprotein, atherogenic index, and cardiac risk factors, which are related to dyslipidemia—a major risk factor for heart disease. The contents of TC and TG, as well as the lipid droplets of HCD-induced hepatic accumulation in the liver tissue, were suppressed by EAT. Taken together, these findings suggest the possibility of developing EAT as a therapeutic agent for improving HCD-induced obesity and hyperlipidemia.

1. Rats fed on a protein-free high-carbohydrate diet for 7 days metabolized dimethylnitrosamine at only 55% the rate of rats fed on a commercial diet. 2. Dimethylnitrosamine was metabolized by liver slices from rats fed on the protein-free diet at less than half the rate attained by slices from rats fed on a commercial diet. But kidney slices from these rats metabolized dimethylnitrosamine at the same rate as kidney slices from rats on a commercial diet. 3. Methylation by dimethylnitrosamine (70mg/kg body wt.) of N-7 of guanine of the liver RNA and DNA of rats fed on a protein-free diet was only slightly higher than in rats fed on a normal diet given 27mg/kg body wt. In contrast, the methylation by dimethylnitrosamine of guanine in kidney nucleic acids of these rats was three times that in the rats fed on a normal diet. 4. In rats fed on a protein-free diet the incidence of kidney tumours produced by a single dose of dimethylnitrosamine is increased.

Schisandrae Fructus (SF), the fruit of Schisandra chinensis (Turcz.) Baillon, has been used for the treatment of liver injury and metabolism-related disorders in China. The objective of this study was to investigate the effects of supplementation with ethanol extract of SF seed (EtSF-S) on serum/hepatic lipid and glucose levels as well as fecal total cholesterol (TC) contents in mice fed a normal diet (ND) or high-fat/fructose diet (HFFD) containing 15% lard oil and 15% fructose. Female ICR mice (18–20 g in body weight) were fed with ND or HFFD for 3 months, and then EtSF-S was added to both chow diets at increasing concentrations of 1, 5, and 10% (w/w). Thirty days later, serum and hepatic lipids, including TC, triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and glucose, were measured. Dietary supplementation with EtSF-S reduced hepatic TC (36 and 18%) and TG levels (38 and 28%) and increased serum HDL/LDL ratio (16 and 26%) in both ND- and HFFD-fed mice, respectively. Moreover, supplementation with EtSF-S elevated serum HDL (31%) in HFFD-fed mice and reduced serum LDL (27%) in ND-fed mice. EtSF-S treatment reduced fat mass (40%) in ND-fed mice and increased fecal TC contents (33%) in HFFD-fed mice. EtSF-S supplementation decreased hepatic glucose contents (29%) in both ND- and HFFD-fed mice. However, diet supplemented with EtSF-S elevated serum TG levels (up to 123%) and hepatic size (28%), but more importantly, suppressed the body weight gain (approximately 130%) in mice fed with HFFD. These findings suggested that dietary supplementation with EtSF-S as natural herbal function food may be a useful strategy for the treatment of patients with fatty liver disease or overweight without a high intake of sugar and fat.

Both apolipoprotein gene polymorphism and high-carbohydrate diet have been found to be associated with serum lipid levels. However, the effects of their interaction on serum lipid profiles have not been well elucidated yet. We assessed the hypothesis that the subjects with different genotypes of the -75G/A polymorphism in the promoter region of the apolipoprotein A-I gene ( APOA1 ) have different serum lipid responses upon a high-carbohydrate diet. Fifty-six healthy university students (27 males and 29 females, 22.89±1.80 years) were given a washout diet of 54% carbohydrates for seven days, followed by a high-carbohydrate diet of 70% carbohydrates for six days without total energy restriction. Anthropometric indexes and serum lipids at baseline, after the washout diet, and after the high-carbohydrate diet, as well as the APOA1 -75G/A polymorphism were analyzed. The male A carriers of the APOA1 -75G/A polymorphism consistently had higher levels of apolipoprotein A-I ( p =0.008 at baseline, p =0.031 after the washout diet, and p =0.009 after the high-carbohydrate diet diet), but higher levels of high-density lipoprotein cholesterol (HDL-C) only at baseline ( p =0.048) and after the high-carbohydrate diet ( p =0.042) than the males with the GG genotype, and experienced increases in HDL-C ( p =0.023) and apolipoprotein A-I ( p =0.012) and decreases in body weight ( p =0.017) and body mass index (BMI) ( p =0.018) after the high-carbohydrate diet when compared to those after the washout diet. In conclusion, the high-carbohydrate diet can increase the serum HDL-C and apolipoprotein A-I concentrations in the males carrying the A allele of the APOA1 -75G/A polymorphism. The effects are associated with the decreases of body weight and BMI. These results may provide experimental evidences for the personalized dietary interference in the country with the largest population in the world.

The purpose of this study was to examine the metabolic consequences of a moderate variation in dietary fat content of male endurance athletes during submaximal exercise. Six males (age, 29.8 ± 11 years; weight, 72.3 ± 10 kg) · with an average maximum oxygen uptake (V̇O2max) of 66 ± 10 ml/kg/min were tested on their normal diet and 3 experimental diets. The energy contributions from protein, carbohydrates, and fats were 16/59/22 (3% alcohol), 14/53/33, 13/72/15, and 16/61/23% for the normal diet (N), fat supplemented diet (F), high carbohydrate diet (C), and adjusted normal diet (AN), respectively. The F diet was designed to significantly increase fat content compared to the normal diet and be easily maintained by the athletes. Caloric content of the F, C, and AN diets were adjusted to meet estimated total daily energy expenditure. The difference between the N and AN diets is that the AN has been adjusted to meet estimated total daily energy expenditure. The diets were randomly assigned after substrate utilization testing on the N diet and were consumed for 7 days prior to testing. Substrate utilization was recorded at steady state (73 ± 1.4% of V̇O2max) while running on a treadmill for 40 min. There were no significant differences in respiratory exchange ratio between any of the dietary manipulations. No significant differences were observed for lactate, V̇O2, or HR during submaximal testing on the N, F, C, and AN diets. These data indicate that a fat supplemented diet did not affect substrate utilization during 40 min of steady-state submaximal exercise when compared to a high carbohydrate diet or the participant’s normal and adjusted normal diets.

Activating Transcription Factor

Chronic feeding of HCD (high-carbohydrate diet) is one of the major contributors to the prevailing of metabolic diseases. ATF4 (activating transcription factor 4) has been shown to play an important role in the regulation of glucose metabolism and obesity development; however, it is unclear how ATF4−/− mice respond to HCD. In the present study, we show that 8 weeks of HCD results in significant higher accumulation of TAGs (triacylglycerols) in livers and impairment in glucose tolerance in ATF4+/+ mice, but not in ATF4−/− mice, compared with those on a normal diet. Meanwhile, energy expenditure is further enhanced by HCD in ATF4−/− mice. Moreover, we show that ATF4 deficiency suppresses HCD-induced SCD1 (stearoyl-CoA desaturase 1) expression, furthermore, oral supplementation of the main product of SCD1 oleate (18:1) increases TAG accumulation in livers of ATF4−/− mice. Taken together, these results suggest that ATF4 deficiency is protective for HCD-induced hepatic steatosis and impairment of glucose tolerance and insulin sensitivity. Furthermore, the resistance to hepatic steatosis is at least in part due to suppression of SCD1 expression under HCD.

Background and Objective: Angiotensinogen (AGT) is the unique precursor of the renin angiotensin system. Our previous studies demonstrated that inhibition of AGT markedly reduced development of atherosclerosis and ablated body weight gain induced by a saturated fat-enriched diet. In addition to high fat intake, high carbohydrate consumption is an important component of contemporary diets. The purpose of this study was to determine whether AGT inhibition prevented atherosclerosis and obesity in LDL receptor -/- mice fed a high carbohydrate diet. Methods and Results: Eight week old male LDL receptor -/- mice were randomized to receive either control or AGT antisense oligonucleotides (ASO; 50 mg/kg/week intraperitoneal injection; N = 10 mice/group). Feeding a high carbohydrate diet was initiated after 6 weeks of ASO injection, and maintained for 12 weeks with continuous ASO injection. AGT-ASO administration profoundly reduced plasma AGT concentrations (Control vs AGT ASO: 3582 ± 117 vs 227 ± 15 ng/ml; P<0.001). High carbohydrate diet feeding resulted in profound increases of plasma cholesterol concentrations in both groups. Atherosclerotic lesions in aortic arches were measured using an en face method after termination. AGT inhibition led to significant decreases (P<0.001) in percentage lesion areas of aortic arches. Prior to high carbohydrate diet feeding, there was no difference of body weight between the two groups (Control vs AGT ASO: 26.6 ± 0.6 vs 25.9 ± 0.7 g; P=0.4). Although high carbohydrate diet only increased body weight modestly, mice injected with AGT ASO had less increases of body weight compared to mice injected with control ASO (Control vs AGT ASO: 28.5 ± 0.6 vs 26.8 ± 0.6 g; P<0.05). Echo MRI analyses demonstrated that the lower body weight in mice administered AGT ASO was attributed to less fat mass gain, whereas lean mass was comparable between the two groups. Additionally, AGT inhibition resulted in lower blood hemoglobin A1c (5.5 ± 0.1 vs 5.1 ± 0.1%; P=0.005). Conclusions: AGT inhibition reduces high carbohydrate diet-induced atherosclerosis and body weight gain.

We examined the effect of dietary carbohydrate intake on post-exercise glycogen recovery. Male Institute of Cancer Research (ICR) mice were fed moderate-carbohydrate chow (MCHO, 50%cal from carbohydrate) or high-carbohydrate chow (HCHO, 70%cal from carbohydrate) for 10 days. They then ran on a treadmill at 25 m/min for 60 min and administered an oral glucose solution (1.5 mg/g body weight). Compared to the MCHO group, the HCHO group showed significantly higher sodium-D-glucose co-transporter 1 protein levels in the brush border membrane fraction (p = 0.003) and the glucose transporter 2 level in the mucosa of jejunum (p = 0.004). At 30 min after the post-exercise glucose administration, the skeletal muscle and liver glycogen levels were not significantly different between the two diet groups. The blood glucose concentration from the portal vein (which is the entry site of nutrients from the gastrointestinal tract) was not significantly different between the groups at 15 min after the post-exercise glucose administration. There was no difference in the total or phosphorylated states of proteins related to glucose uptake and glycogen synthesis in skeletal muscle. Although the high-carbohydrate diet significantly increased glucose transporters in the jejunum, this adaptation stimulated neither glycogen recovery nor glucose absorption after the ingestion of post-exercise glucose.
