Cholesterol is an essential substance for the body. The role of cholesterol as material hormones,cell membranare needed by the body. This conditionchanges into a distrubtion if the cholesterollevels in the blood increase. Weight becomes one of this trigger. The consumption of high-fat foodsincrease weight which resulting in the increase of cholesterol cases. The purpose of this study was todetermine the level of correlations between weight and cholesterol levels after being given a high-fatdiet.The study used rats (Rattus norvegicus) sex male, 16 rats with age between 1-2 months. Rats weightrange between 100-150 gr and in healthy conditions. The giving of high-fat diet were in the form ofchicken feed, duck eggs, goat oil, lard and flour for 8 weeks. The data measurement done by scales andmeasuringcholesterol levels through the end of the tail by means of easy touch. The data analysis weredone to understand level of correlation between variables. The presentation of the data used tables. Theresults showed body weight of rats did not change after administration of a high-fat diet. The cholesterolslevels of the subjects were high. Theadministration of high-fat diet from egg yolk dan goat oilcouldincrease the level of cholesterol. There was a correlation between weight and cholesterol levels afterbeing given a high-fat diet (p <0.5). It was needed to repeatthe measurements to determine changes incholesterol levels and other factors that affect thigh blood to cholesterol levels.

In the present study, the methanolic extract of Moringa oleifera leaves (MEMOL) was evaluated for antiobesity activity in rats. The antiobesity potential of MEMOL was studied against high fat diet-induced obesity (HFD) in rats. In this study, chronic administration of HFD in rats produced hypercholesterolemia (116.2 ± 0.27 mg/dL), which led to an increase in the body weight (225 gr), total cholesterol, triglycerides (263.0 ± 4.69 mg/dL), and attenuation in the levels of HDL (34.51 ± 2.20 mg/dL) as well as changes in body temperature of animals. Treatment of obese rats with MEMOL for 49 days resulted in a significant (P<0.001) change in body weight, total cholesterol, triglycerides, and LDL level along with a significant (P<0.001) increase in body temperature as compared to the HFD-induced obesity. MEMOL treated rats also showed a significant decrease in the level of liver biomarkers, organ weight, and blood glucose level. Further, rats treated with MEMOL (200 mg and 400 mg/kg) show reduced atherogenic index (1.7 ± 0.6 and 0.87 ± 0.76). The results indicate that the rats treated with Moringa oleifera (MO) have significantly attenuated the body weight without any change in the feed intake and also elicited significant thermogenic effect and to act as hypolipidemic and thermogenic property in obesity related disorders.

: Probiotic dark tea (PDT) is a novel kind of dark tea produced by fresh albino tea leaves and fermented with specific probiotics. Our study demonstrates that PDT can ameliorate high-fat diet-induced overweight and lipid metabolic disorders and shows no acute or subacute toxicity in Sprague-Dawley (SD) rats. Daily intragastric administration of 5% PDT infusion for 14 days caused no obvious effect on general physiological features and behaviors of rats. Oral administration of 1%, 2%, and 3% of PDT infusion for six weeks had no influence on the biochemistry and histopathology of rats’ organs and blood, as well as the body weight and ratios of organ/body weight. To investigate its anti-obesity activity, SD rats were randomly divided into four groups, treated with normal diet + water (Group I), high-fat diet + water (Group II), high-fat diet + 3% traditional dark tea infusion (Group III), high-fat diet + 3% PDT infusion (Group IV). After six weeks, the body weight, serum total triacylglycerol (TG) and serum total cholesterol (TC) levels of rats in Group II were significantly increased and the high-density lipoprotein cholesterol (HDL) levels were significantly decreased compared with those in the other three groups. Both traditional dark tea and PDT treatment effectively counteracted the adverse effect of a high-fat diet in SD rats. These results suggest that PDT could be applied for the prevention of obesity, which ameliorates overweight and lipid metabolic disorders and which shows no acute or subacute toxicity.

Introduction: Sedentary lifestyle and excessive calorie intake are risk factors for CVD. We have demonstrated the cardioprotective effect of exercise in aged mice and the critical role of visceral adiposity and its profibrotic secretome in increasing cardiovascular risks in obesity and aging. The association between exercise, lowered plasma leptin and reduced inflammatory leukocytes has been recently shown in patients with atherosclerosis. It remains unclear whether elevated plasma leptin can preserve or alter cardiovascular function in obesity. Methods: We analyzed the effect of high fat diet (HFD) in C57BL/6J male mice on the heart in terms of function, structure, histology and key molecular markers. Two interventions were used: 1) active fat mass loss via exercise (daily swimming) during HFD; 2) passive fat mass loss via surgical removal of the visceral adipose tissue (VAT lipectomy) followed by HFD. Results: HFD increased body weight and adiposity, leading to higher plasma leptin, glucose and insulin levels, compared to control diet (CD) mice. HFD impaired left ventricle (LV) structure (hypertrophy, interstitial fibrosis) and cardiac function (echocardiography, in vivo hemodynamics). Atria of HFD mice had enhanced pro-inflammatory protein production. Exercise reduced circulating leptin levels in HFD mice by 50%, in line with fat mass loss. In contrast, lipectomy reduced visceral fat mass, but body weight, adiposity and plasma leptin did not change. Both exercise and VAT lipectomy improved cardiac contractility, reversed collagen deposition and oxidative stress in HFD mice. Both interventions downregulated LV pro-inflammatory markers. We proved the role of leptin in cardiac remodeling in vitro by incubating primary cardiac fibroblasts with hyperleptinemic plasma from HFD mice. Remarkably, plasma from HFD-EX (exercise) suppressed the fibro-proliferative and pro-inflammatory responses of cardiac fibroblasts. Conclusions: Leptin directly contribute to cardiac fibrosis in obesity via activation and proliferation of cardiac fibroblasts. Understanding how leptin signals to the heart might have implications in a wide range of CVD, potentially helping early stratification and personalized care.

The effect of the extract of Ligustrum lucidum fruits (LFE) and its major secoiridoid (LFS), (8- E)-nüzhenide, on obesity was investigated using high fat-diet (HFD)-induced C58BL/6J obese mice. LFE and LFS were administered at the doses of 300 mg/kg and 30 mg/kg, respectively, for 6 weeks. The anti-obesity activity was evaluated by measuring body weight, epididymal fat and metabolic plasma parameters. On Day 42, the body weight of the LFS-treated group was significantly lower compared with the HFD-treated group. Body weight gain was also reduced by 23.2% and 32.0% in the LFE- and LFS-treated groups, respectively, compared with the HFD group. In addition, the weight of the epididymal fat in the mice was significantly decreased in the HFD+LFS group. The food efficiency ratios (FERs) of the HFD+LFE and HFD+LFS groups were also lower compared with the HFD group with the same food intake. Metabolic parameters that had increased in the HFD group were decreased in the HFD+LFE and HFD+LFS groups. In particular, the increased triglyceride values were significantly reduced in the HFD+LFS group. These results show that treatment with LFE and LFS decreased HFD-induced obesity, mainly by improving metabolic parameters, such as fats and triglycerides. Therefore, LFE and LFS have potential benefits in regulation of obesity.

Abstract Objectives The dietary fat content plays an important role in the regulation of chronic metabolic diseases such as obesity and type 2 diabetes. Here, we tested the impacts of triacylglycerol structure on the body weight gain and food intake of mice in a high-fat diet (HFD) setting. Methods Male C57/BL6J mice at 6 weeks old were fed one of the following three diets for 6 weeks, Teklad Rodent Diet chow diet (number 8640), the chow diet containing 36% (w/w) 1,2-Dipalmitoyl-3-oleoylglycerol (PPO), or the chow diet containing 36% (w/w) 1,3-Dipalmitoyl-2-oleoylglycerol (POP). Each group contained 9 mice, and their food intake and BW were measured daily. The mice were euthanized after 6 weeks (12 weeks old) for tissue sample collection. Results Both high HFD groups had significantly higher BW gain and caloric intakes than the chow diet group. Mice fed the POP diet had a lower percentage of BW gain and consumed less accumulated calories than those fed the PPO diet, as well as a significantly lower liver to BW ratio. Since week 4, the body BW rate of the POP group started to be lower than that of the PPO diet group. Conclusions TAG structures in an HFD setting affect the BW gain rate and obesity in mice. The different structures of fat added to affect the food intake and BW gain differently in an HFD setting. In the future, we would like to compare the changes of the hepatic lipogenesis enzyme in these mice. This will help us to understand how the triacylglycerol structures in the diet affect lipid metabolism in mice. Funding Sources Internal.

Abstract Objectives Colorectal cancer (CRC) is one of the most prevalent cancer worldwide. Evidence from epidemiological studies shows that the incidence rate of CRC among elders with age ≥ 50 years is gradually decreased, whereas the rate continuously rise in adults with age &lt; 50 years. Along with the rise of CRC in young adults, a significantly increasing trend in obesity is also observed in youth. The present study aims to investigate how the early-life nutrition influences the intestinal tumorigenesis later in mouse with an age equivalent to an age &lt; 50 years in human. Methods APC1638N mice (4 weeks of age) were fed a low-fat diet (N = 22; LF: 10% kcal from fat) or a high-fat diet (N = 23; HF: 60% kcal from fat) for 8 weeks, which is equivalent to child/adolescent age in humans. After that, all animals were switched to standard chow diet (LabDiet #5P76) and fed for additional 12 weeks before sacrifice. Tumors were examined and the expression tumorigenic Wnt-signaling downstream genes (Cyclin D1, c-Myc and Axin 2) in the intestine were assessed. Results Our results showed that compared to LF group, the body weight of both male and female mice significantly increased after 8-week HF feeding (P &lt; 0.05). After switching to the standard chow diet for further 12 weeks feeding, the increase of body weight in HF group remained, although the degree of magnitude reduced, and a statistical significance only shown in female mice (P &lt; 0.05). There were a higher tumor incidence (P = 0.051) and tumor multiplicity (P &lt; 0.05) in males than female.  No interactions between gender and diet were observed. The HF group had a higher tumor incidence (P = 0.088) and tumor size (P &lt; 0.05) when compared to the LF group. The expression of Wnt-signaling downstream gene, c-Myc, was significantly increased in the HF group at 24-week of age (P &lt; 0.01). Conclusions A short term of high-fat diet in early life tends to promote intestinal tumorigenesis in adults as indicated by a mild increase in tumor incidence and a significant increase in tumor size.

The present study was aimed to evaluate the anti-obesity property of Tamarindus indica seed extract (TSE) on high fat-fed obese rats. TSE was prepared by cold maceration method and qualitative phytochemical studies had been carried out. In vitro cell viability assay (MTT assay) was and oil red staining for evaluating the lipid accumulation in cells was carried out using 3T3-L1 cells, and leptin levels was evaluated by ELISA. In-vivo Obesity was induced in experimental rats by administration of a high-fat diet for 04 weeks. The anti-obesity effect was screened by oral administration of TSE at two different dose levels i.e., 250 and 500mg/kg b. Wt. Along with a high-fat diet for a period of 04 weeks. The anti-obesity activity is estimated in terms of body weight gain, serum triglycerides (TG), Total cholesterol (TC). In -vitro studies revealed that the TSE has no cytotoxic effect, Administration of a high-fat diet for 04 weeks significantly increased the body weight, serum triglycerides, cholesterol. Upon treatment with TSE, a significant dose-dependent alteration in body weight, triglycerides, cholesterol levels were observed, inferring the anti-obesity property of Tamarindus seed extract.
