New research offers insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. The findings advance knowledge about leptin and weight gain, and also suggest a potential ...

Leptin is a molecule that is well known in obesity research; it is released by white fat cells, reducing appetite and contributing to the maintenance of healthy levels of blood sugar and weight. The ...

Leptin, the hormone secreted by fat cells that plays an important role in food intake, has been described for the first time in a cold-blooded vertebrate, the South African clawed frog Xenopus. Leptin ...

Twenty years after the hormone leptin was found to regulate metabolism, appetite, and weight through brain cells called neurons, Yale School of Medicine researchers have found that the hormone also ...

Your body maintains a biological “set point” for weight, beyond calories, through powerful hormonal and neural feedback loops that make it resist weight loss.

To keep the human brain supplied with energy when food was scarce, mammals evolved the ability to switch from burning carbohydrates to burning fat in order to preserve skeletal muscle that would ...

New Haven, Conn. -- In a new study, Yale researchers offer insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. Their findings advance knowledge about leptin and ...

The fundamental biology of leptin and the leptin system is summarised. The hormone is produced in several organs, but primarily white adipose tissue, and is subject to acute regulation, particularly ...

Researchers have discovered in fruit flies a key metabolic hormone thought to be the exclusive property of vertebrates. The hormone, leptin, is a nutrient sensor, regulating energy intake and output ...

Obesity and cancer are two major health challenges of our time, yet the link between them remains only partially understood. New research now highlights a molecular chain of events in estrogen ...

Before a baby is ever born, critical supply chain problems with nutrition and oxygen can result in premature birth or even death and increase the child and mother's lifelong risk of cardiovascular ...
