Defining Clinical Leptin Resistance - Challenges and Opportunities
Abstract
The lack of a universally accepted definition of the term “leptin resistance” led the National Institutes of Health to hold a workshop, “Toward a Clinical Definition of Leptin Resistance”. Leptin resistance is generally defined as the failure of endogenous or exogenous leptin to promote anticipated salutary metabolic outcomes in states of over-nutrition or obesity, although the hormone's inability to promote desired responses in specific situations results from multiple molecular, neural, behavioral, and ...

Leptin Resistance: A Possible Interface of Inflammation and Metabolism in Obesity-Related Cardiovascular Disease
Nonstructured Abstract
Leptin is an adipocyte-derived hormone and cytokine that regulates energy balance through a wide range of functions, including several important to cardiovascular health. Increased circulating leptin, a marker of leptin resistance, is common in obesity and independently associated with insulin resistance and cardiovascular disease (CVD) in humans. Mechanisms of leptin resistance include genetic mutation, leptin self regulation, limited tissue access and ...

Leptin and Obesity: Role and Clinical Implication
Abstract
The peptide hormone leptin regulates food intake, body mass, and reproductive function and plays a role in fetal growth, proinflammatory immune responses, angiogenesis and lipolysis. Leptin is a product of the obese (ob) gene and, following synthesis and secretion from fat cells in white adipose tissue, binds to and activates its cognate receptor, the leptin receptor (LEP-R). LEP-R distribution facilitates leptin’s pleiotropic effects, playing a crucial role in regulating body mass via a negative feedback mechanism between ...

Leptin resistance: underlying mechanisms and diagnosis
Abstract: Leptin and its receptors have been identified as key regulators of body weight and energy homeostasis. A decrease in tissue sensitivity to leptin leads to the development of obesity and metabolic disorders, such as insulin resistance and dyslipidemia. Mechanisms underlying the development of leptin resistance include mutations in the genes encoding leptin and its receptors, as well as proteins involved in self-regulation of leptin synthesis and blood–brain barrier permeability. Leptin resistance encompasses a complex ...

The Leptin System and Diet: A Mini Review of the Current Evidence
Abstract
Leptin promotes satiety and modulates energy balance and weight. Diet-induced obesity leads to leptin resistance, exacerbating overeating. We reviewed the literature on the relationship between diet and leptin, which suggests that addressing leptin resistance through dietary interventions can contribute counteracting obesity. Albeit some limitations (e.g., limited rigor, small samples sizes), studies in animals and humans show that diets high in fat, carbohydrates, fructose, and sucrose, and low in protein are ...

Dietary Components in the Development of Leptin Resistance
ABSTRACT
Classically, leptin resistance has been associated with increased body fat and circulating leptin levels, and the condition is believed to contribute to the onset and/or maintenance of obesity. Although a great deal is known about the central nervous system mechanisms mediating leptin resistance, considerably less is known about the role of diet in establishing and maintaining this altered hormonal state. An exciting new finding has recently been published demonstrating the existence of leptin resistance in normal-weight ...

Leptin, Obesity, and Leptin Resistance: Where AreWe 25 Years Later?
Abstract: Leptin, a hormone that is capable of eectively reducing food intake and body weight, was initially considered for use in the treatment of obesity. However, obese subjects have since been found to have high levels of circulating leptin and to be insensitive to the exogenous administration of leptin. The inability of leptin to exert its anorexigenic eects in obese individuals, and therefore, the lack of clinical utility of leptin in obesity, is defined as leptin res stance. This phenomenon has not yet been ...
