N2 - Previous reports have suggested that the abrogation of gastric inhibitory polypeptide (GIP) signaling could be exploited to prevent and treat obesity and obesity-related disorders in humans. This study was designed to determine whether immunoneutralization of GIP, using a newly developed specific monoclonal antibody (mAb), would prevent the development of obesity. Specific mAb directed against the carboxy terminus of mouse GIP was identified, and its effects on the insulin response to oral and to intraperitoneal (ip) glucose and on weight gain were evaluated. Administration of mAb (30 mg/kg body wt, BW) to mice attenuated the insulin response to oral glucose by 70% and completely eliminated the response to ip glucose coadministered with human GIP. Nine-week-old C57BL/6 mice injected with GIP mAbs (60 mg·kg BW−1·wk−1) for 17 wk gained 46.5% less weight than control mice fed an identical high-fat diet (P 0.001). No significant differences in the quantity of food consumed were detected between the two treatment groups. Furthermore, magnetic resonance imaging demonstrated that subcutaneous, omental, and hepatic fat were 1.97-, 3.46-, and 2.15-fold, respectively, lower in mAb-treated animals than in controls. Moreover, serum insulin, leptin, total cholesterol (TC), low-density lipoprotein (LDL), and triglycerides were significantly reduced, whereas the high-density lipoprotein (HDL)/TC ratio was 1.25-fold higher in treated animals than in controls. These studies support the hypothesis that a reduction in GIP signaling using a GIP-neutralizing mAb might provide a useful method for the treatment and prevention of obesity and related disorders.

The following sections of this article will present arguments and evidence in support of the above assumptions and hypotheses. Other evolutionary theories for eating disorders will be briefly reviewed and will be contrasted with the present hypothesis and a number of predictions based upon this hypothesis will be made. Figure 1 presents a brief outline of the reasoning behind the present hypothesis.

Critical periods in childhood for the development of obesity.

The increasing prevalence of childhood obesity, ranked as a critical public-health problem in the 21st century, has led policy-makers in several countries to take preventive actions. The responsibility for obesity prevention among young children lies not only in the hands of parents and families but also in the hands of national governments, local governments, communities, non-profit organizations, the food industry, the media, and schools and local education authorities.

Childhood obesity is associated with a wide range of disorders that affect multiple organ systems. Increased body weights in children may lead, for instance, to insulin resistance, glucose intolerance, hypertension, and orthopaedic problems.1 Some of these conditions produce clinical symptoms in the patient, while others do not. The physiologic and metabolic changes associated with obesity in children tend to follow them into adult life and increase the risks for disease, disability, and death.

Applying the principles of positive emotional plasticity to rewiring the stress response is a novel intervention that merits further evaluation. Stress-processing circuitry is formed early in life or during periods of trauma, and stored in implicit memory systems. Excessive and, especially, inappropriate activation of the stress circuitry strengthens maladaptive circuits and can lead to persistent maladaptive (allostatic) brain states. We hypothesize that with the recognition that dominant neurocircuitry can lead to persistent brain states, a new approach can be utilized for health care treatment of stress-related symptoms and diseases. Potentially, providing an indi-vidual with the skills to reconsolidate those stress citcuits, and thus decrease or reverse allostatic load, may improve health and well-being. Therefore, we propose a new paradigm for health care – focusing on rewiring the stress response in favor of adaptive neuroplasticity

The Obesogen Hypothesis and the Obesity Epidemic | PSR

Obesity is an acquired condition; nobody is born obese. Once an increased amount of body fat is acquired, the body strikes a new, stabilized energy balance.3 So far, published data do not support the idea that this development is reversible. Therefore, a child’s developmental influences are of central interest when searching for effective preventive measures and prevention should start as early as possible.

Evolutionary theory deals with questions of ultimate causation; that is the adaptive function of a certain trait or organ in the ancestral environment. However, evolutionary hypotheses are compatible and consistent with layers of proximate causation. Such proximate explanations will focus on biochemical, physiological, developmental, social and other immediate causes for the expression of a particular characteristic (Symons,1987; Thornhill & Thornhill, 1987).
