Neurons in the human brain play a crucial role in appetite, satiety, and metabolism. Research has revealed more about the neuronal circuits that are involved in these processes, as well as obesity.

Leptin is a hormone that comes from fat cells. It helps control food intake by sending signals about hunger to the hypothalamus in the brain. This process regulates appetite. Leptin regulates energy ...

NEW YORK (Reuters Health) - Studies in obese mice suggest that a sensor in the brain that normally detects the fat hormone leptin -- causing a series of events that keep energy balance in check -- ...

Most obese patients grow resistant to satiety signals from the hormone leptin. A new study shows that leptin sensitivity can be restored in mice, leading to weight loss. Worldwide obesity rates have ...

Hormone absence or inactivity is common in congenital disease, but hormone antagonism remains controversial. Here, we characterize two novel homozygous leptin variants that yielded antagonistic ...

Leptin is a hormone – a chemical messenger that helps different body parts work together. Leptin sends a signal to your brain that helps you feel full and less interested in food. You may hear it ...

Obesity has become a global epidemic affecting diverse populations and leading to metabolic syndrome across different sexes and age groups. A significant aspect of obesity is the development of leptin ...

Those little fruit flies floating around the ripening cantaloupes pack some fat between their tiny wings. They’re cold-blooded and burn their fat to warm up. “They have really beautiful fat, the flies ...

Loss of a protein essential for degrading mRNA from the forebrain of mice leads to increased appetite and the onset of obesity, a new study finds. Obesity is an increasingly serious public health ...

In a new study published in iScience, researchers created mutant mice without XRN1 in the forebrain. XRN1 is a protein that plays a crucial role in degrading mRNA. The scientists found that production ...

Medically reviewed by Danielle Weiss, MD Key Takeaways Hormonal belly is when your belly gets big from hormones being out of balance.Hormone imbalances that can cause a hormonal belly include cortisol ...

Researchers have identified a protein that plays a key role in how the brain regulates appetite and metabolism. Loss of the protein, XRN1, from the forebrain, resulted in obese mice with an insatiable ...
