Metabolism exogenous obesity – Dyslipidemia in Obesity: Mechanisms and Potential Targets

The abnormalities described thus far include: impaired glucose tolerance, resistance to ketosis, impaired fatty acid mobilization with fasting or epinephrine administration, inhibition of glycolysis, increased urinary ketosteroid and ketogenic steroids, excessive insulin response following a glucose load, and impaired secretion of growth hormone with starvation.

Interactions between genes, obesity and lipid levels but also with the type of dietary fat consumed have recently been described [,]. Given that diets high in simple sugars and processed carbohydrates tend to be calorie-dense, metabolsim in satiety-promoting fiber and other nutrients, affordable, widely available, and often heavily marketed, it is perhaps not surprising that such diets can favor an increase of overall energy intake. Evidence that reduced NEAT contributes independently to obesity pathogenesis stems from the observations that NEAT tends to be lower in individuals who are obese vs lean, and it does not appear to change in response to either weight gain in normal weight subjects or weight loss in subjects who are obese Although such individuals exist, they are rare

Nascent HDL particles acquire free cholesterol from peripheral tissues. Alternatively, LPL-enriched remnants of chylomicrons and VLDL may be transported to the tissues where interaction with proteoglycans and lipoprotein receptors lead to particle removal. Lipoprotein lipase LPLan enzyme that hydrolyzes circulating apolipoprotein-bound acylglycerides at the surface of many cell types including adipocytes and myocytesalso appears to affect the partitioning of fatty acids in ways that affect both absolute and relative fat mass. Recent work has identified several unique and unanticipated properties of AgRP neurons.

Li, X. Deeb S. Additionally, fatty liver, accompanied by insulin resistance and diabetes, is usually observed in lipodystrophic patients, where the exogenus liver usually progresses to cirrhosis. Conclusions The pathophysiology of the typical dyslipidemia observed in obesity is multifactorial and includes hepatic overproduction of VLDL, decreased circulating TG lipolysis and impaired peripheral FFA trapping, increased FFA fluxes from adipocytes to the liver and other tissues and the formation of small dense LDL. Nguyen, J. As noted earlier, in free-living adults, energy intake and expenditure are tightly coupled over long time intervals.

A key question, therefore, is how the energy homeostasis system comes to defend an elevated level of fat mass analogous to the defense of elevated blood pressure in patients with hypertension. Thus, some individuals who are obese may simply require more leptin and hence body fat to fully engage relevant neurocircuits Such effects seem worthy of investigation independent of the impact of BPA exposure on obesity risk.

In summary, beyond the contribution of visceral fat-secreted adipokines to cardiovascular disease, the presence of cardiac ectopic fat does also contribute: firstly, due to mechanical functions, and secondly, due to cardiac ectopic fat-released adipokines which would link the ectopic cardiac fat depot, the vasculature, and the myocardium, thus playing key roles in the pathogenesis of cardiovascular disease.

Endogenous obesity is endogenous merely in the sense that in the creation of such a disproportion a fall in the rate of oxidation in the body plays a role.

These observations are consistent with the theory that the undernourished fetus experiences changes in the energy metabolism exogenous obesity system that are adaptive when limited nutrient availability persists, but become maladaptive in a nutrient-rich environment Tenkanen L. Incidence of coronary heart disease events in a normal population is inversely related to the serum HDL-cholesterol concentration - low levels carry an increased coronary risk HDL is thought to be anti-atherogenic and high HDL levels are cardioprotective. Because this inhibitory input becomes quiescent during fasting, AgRP neurons are activated and increase the drive to eat. These data collectively support the notion that developmental exposure to either undernutrition or obesity can increase susceptibility to obesity in offspring, and that the timing of exposure strongly influences such effects.

General perspectives on metabolism exogenous obesity pathogenesis have swung from early conceptualizations of obesity as a storage disease of adipose tissue analogized presumably to some of obewity earliest identified inborn errors of metabolism by Garrod to more recent brain-centric models, in which the brain, by virtue of its operational control of food intake and energy expenditure, imposes excess calories on passive adipocytes.
