Leptin selectively decreases visceral adiposity and enhances insulin action.

Intraabdominal adiposity and insulin resistance are risk factors for diabetes mellitus, dyslipidemia, arteriosclerosis, and mortality. Leptin, a fat-derived protein encoded by the ob gene, has been postulated to be a sensor of energy storage in adipose tissue capable of mediating a feedback signal to sites involved in the regulation of energy homeostasis. Here, we provide evidence for specific ...

Decreased visceral adiposity accounts for leptin effect on hepatic but not peripheral insulin action.

Leptin decreases visceral fat (VF) and increases peripheral and hepatic insulin action. Here, we generated similar decreases in VF using leptin (Lep), β3-adrenoreceptor agonism (β3), or food restriction (FR) and asked whether insulin action would be equally improved. For 8 days before the in vivo study, Sprague-Dawley rats ( n = 24) were either fed ad libitum [control (Con)], treated with Lep o...

Magnesium supplementation enhances insulin sensitivity and decreases insulin resistance in diabetic rats

Objective(s): Diabetes mellitus has been suggested to be the most common metabolic disorder associated with magnesium deficiency. This study aimed to investigate the effects and mechanisms of magnesium supplementation on insulin receptor activity in elderly type 2 diabetes using a rat model and to provide experimental evidence for insulin resistance improvement by magn...

Visceral adiposity, insulin resistance and cancer risk

BACKGROUND There is a well established link between obesity and cancer. Emerging research is characterising this relationship further and delineating the specific role of excess visceral adiposity, as opposed to simple obesity, in promoting tumorigenesis. This review summarises the evidence from an epidemiological and pathophysiological perspective. METHODS Relevant medical literature was ide...

Insulin and leptin as adiposity signals.

There is now considerable consensus that the adipocyte hormone leptin and the pancreatic hormone insulin are important regulators of food intake and energy balance. Leptin and insulin fulfill many of the requirements to be putative adiposity signals to the brain. Plasma leptin and insulin levels are positively correlated with body weight and with adipose mass in particular. Furthermore, both le...
