Worldwide obesity rates have more than doubled since 1990, with nearly a billion people now falling into the category. Though a complex interplay of genes, diet, and environment contribute, 90% of ...

How do mammals manage to eat in situations that cause anxiety, step into exposed spaces, or slow down when anxiety drives them to keep moving? A new study pinpoints a leptin-sensitive circuit in the ...

Worldwide obesity rates have more than doubled since 1990, with nearly a billion people now falling into the category. Though a complex interplay of genes, diet, and environment contribute, 90% of ...

For years, scientists have pointed to leptin resistance as a possible cause of obesity. Research led by investigators at the University of Cincinnati (UC) Metabolic Diseases Institute, however, found ...

Leptin is a hormone that helps manage energy. It signals to your brain when you need food or when you’re satiated. But, leptin resistance can cause the brain to miss this signal, which may contribute ...

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 ...

Leptin-sensing neurons in the lateral hypothalamus (colored green) help to overcome anxiety to enable adaptive behaviour. Input from prefrontal cortex is shown in red. White lines show the activity of ...
