Introduction

In the study group, the average z-scores were clearly greater than 0 especially for boys in the younger age groups. The existence of multiple steps at which ARC circuits can recalibrate to match the anticipated external environment likely underlies the extraordinary capacity of these circuits to compensate for early developmental deficits Increases in childhood obesity foreshadows serious health consequences e. Compelling support for the involvement of maternal influences in programming metabolic outcomes first emerged from epidemiological observations in humans.

  • Prescribers should be familiar with these product labels in order to avoid contraindications and to judiciously choose patients based on product cautions. American Medical Association.

  • Mechanistic formulations must draw from disciplines that include: the neuroscience of feeding behavior; the psychology of food reward; the metabolic impact of xrticle nutrients and changes of physical activity; as well as genetics, epigenetics, and developmental biology relevant to energy balance control, and the influence of exposure to environmental variables ranging from endocrine-disrupting chemicals EDCs to socioeconomic factors.

The impact of diet on obesity risk is explained largely by its effect on calorie intake, rather than by changes of either energy expenditure or the internal trim obesity solution bahaya syiah environment. The extent to which changes in diet composition drive the obesity epidemic has been a matter of considerable controversy for decades. The prevalence of overweight and obesity in children and adolescents is different in various European countries. Resistance to diet-induced hypertriglyceridemia and hypercholesterolemia. Kalabiska et al. Although many exposures during development could potentially predispose to obesity in adulthood, we focus here on two that some researchers think contribute to the secular trends in obesity: parental obesity and exposure to EDCs. However, growing evidence indicates that obesity pathogenesis involves processes far more complex than the passive accumulation of excess calories.

There is little question that in the United States obesity rates are linked inversely to socioeconomic status SESespecially among women — In rodents, both sympathetic projections and sympathetic nervous system—dependent stimulation of BAT activity develop during the suckling period 94— Socio-cognitive and nutritional factors associated with body mass index in children and adolescents: possibilities for childhood obesity prevention. Both the time since the last meal and the status of intercurrent fat stores in the body can strongly influence the capacity of these physiologic signals to terminate a meal. An alternative possibility is that gut bacteria generate biological signals such as butyrate and other short-chain fatty acids that impact the energy homeostasis system, and that the composition of gut bacteria influences the nature of these signals Am J Physiol Endocrinol Metab.

The problem with this explanation is that simply increasing the energy harvested from ingested foods should elicit compensatory adjustments elsewhere in the pdf file homeostasis system e. A systematic review of information about more thanadults found that carriers of the common FTO gene variant most consistently associated with obesity were able to reduce their risk through physical activity. Telford, R. Although an acute increase of body-fat mass is often reversible, incremental, sustained increases of body fat typically end up becoming part of the total body-fat mass that is biologically defended.

We see clear evidence arhicle a properly operating energy homeostasis system in the remarkable body-weight stability of individuals who are not obese over long periods of time. The obesity epidemic can be considered a collective response to this environment. Furthermore, the hyperinsulinemia of obesity is typically associated with normal or elevated circulating glucose and fatty acid levelsa combination inconsistent with a state of insulin-mediated cellular starvation. For each participant, height and weight were measured. Such changes might then induce both an adaptive decrease of energy expenditure and an increase of food intake 27, that together conspire to cause obesity. On the other hand, Whelton et al. Additionally, a recent study reported that adjacent to AgRP and POMC neurons in the ARC is a distinct and previously unrecognized subset of excitatory neurons that, when activated, powerfully and rapidly inhibit feeding

Published : 26 February For these reasons, the ability to influence and clinically manipulate energy intake is the more pressing goal where obesity treatment is concerned.

Sequencing of obesity review article pdf file entire exomes of individuals has the potential to address this possibility. Studies that clarify how this occurs are a high priority, as are studies to identify cell types in the gut that convey these effects to the brain and the role of the liver as a potential intermediary in these processes. Studies investigating the adaptive responses of normal-weight humans and animals to changes in body weight support the concept of a physiologically important energy homeostasis system. More work in this area is clearly needed.

These inconsistencies erode public trust and confidence in the scientific process as it pertains to obesity and its treatment, which only further supports nonscientific ideologies and products. This possibility highlights the need to focus beyond neighborhood geographic boundaries. Recent work has identified several unique and unanticipated properties of AgRP neurons. Activation of CGRP PBN neurons is implicated not only in physiological satiety and normal meal termination, but also in anorexia elicited by a variety of aversive stimuli. Related to this issue and to the future identification of obesity therapeutics is an apparent conceptual bias regarding the biological consequences of sequence variants implicated in these studies. Regul Pept.

Individuals who are obese also resist excess weight gain induced by forced overfeeding In contrast, most humans eat multiple meals per day, and each meal constitutes a modest fraction of total daily caloric intake, with the number and size of meals per day ranging widely across populations and cultures. The need to integrate molecular, genetic, developmental, behavioral, and environmental factors highlights the substantial challenge inherent in achieving a comprehensive understanding of obesity pathogenesis. The ontogeny of sympathetic circuits regulating nonshivering thermogenesis hinges on the coordinated development of both the nervous system and its target organ. This effect of exercise may involve a partial reversal of the effects of weight loss to increase muscle work efficiency Superimposed on these influences are the potential roles played by maternal obesity and diabetes. However, without better evidence of a causal relationship between such infectious agents and human obesity, this mechanism seems unlikely to be a major factor underlying the current obesity epidemic.

Introduction

Environmental programming of the maximal capacity of iBAT thermogenesis is correlated with lasting fkle on the number of iBAT-innervating neurons in the sympathetic ganglia The analysis showed that Family level risk factors include higher socioeconomic status and family history of obesity. Although a low rate of resting energy expenditure predicts subsequent weight gain in some studiesand despite growing interest in the contribution made by brown and beige adipose tissue to energy expenditure in humansthe major cause of the energy imbalance implicated in the current obesity epidemic is excessive food intake relative to energy expenditure in the context of sedentary lifestyles. However, we need more evidence to conclude whether these developmental exposures have contributed to the increase of obesity prevalence in human populations in recent decades.

  • Figure Legends: These should be brief, specific and appear on a separate manuscript page after the References section.

  • Although available evidence suggests that EDCs can impact the function of genes important obesity review article pdf file the control of energy balance and adipocyte function, human data and results from in vivo animal studies have yet to clearly demonstrate an increased risk of obesity conferred by developmental EDC exposure. This perspective offers a plausible explanation for the very frequent regain of lost weight that confounds most forms of obesity treatment 10 ,

  • Patients with obesity are at major risk for developing a range of comorbid conditions, including cardiovascular disease CVDgastrointestinal disorders, type 2 diabetes T2Djoint and muscular disorders, respiratory problems, and psychological issues, which may significantly affect their daily lives as well as increasing mortality risks.

In other words, can consumption of different types of foods obesity review article pdf file to weight gain independently of the number of calories consumed? Excess consumption of such foods is linked to rising obesity rates, and it has been suggested that for some individuals consumption of such foods mitigates the stress of daily life —thereby adding to their high inherent reward value. Located in an area of the mediobasal hypothalamus known as the arcuate nucleus ARCAgRP neurons are activated in conditions of negative energy balance and weight loss e. Another area that has yet to be explored mostly due to difficulties finding suitable subjects is whether alleles of genes that protect against obesity exist and can be identified. Sensitive periods for development of circuits regulating BAT thermogenesis are distinct from those that characterize the development of ARC feeding-relevant circuits, in that neither maternal signals of metabolic status 9798 nor maternal environmental exposures 99 during gestation influence the formation of the iBAT depot or the expression of its associated thermogenic machinery.

POMC neurons are also targets for the action of certain anorexic agents, including serotonergic drugs Nat Med. Casagrande, D. Such effects may reflect actions of BPA on brown adipose tissue and physical activity, as well as on white adipose tissue adipogenesis These observations are consistent with the theory that the undernourished fetus experiences changes in the energy homeostasis system that are adaptive when limited nutrient availability persists, but become maladaptive in a nutrient-rich environment ,

On the other hand, an improvement of socio-economic dile in low- and middle-income countries could mean the possibility of mechanization leading to less intensive daily activity, and an increase in access to highly processed foods and fast food 11 However, these observations do not indicate that genetic deficiencies of leptin or its cognate receptor are important causes of human obesity. Behavioral treatment of obesity. Collectively, this evidence supports the possibility of a causal link between the stable transmission of epigenetic marks, parental nutritional status in the periconception period, and programming of subsequent obesity risk.
