A widely prescribed class of weight-loss and diabetes medications may be doing more than improving metabolic health. Drugs such as Ozempic and Wegovy have transformed the treatment of obesity and type 2 diabetes, helping millions lose weight and improve metabolic health. But scientists are increasingly uncovering effects that extend far beyond the scale. Research has [...]

Some effects can be traced to chemical signals inside appetite neurons.

Scientists may have found the brain-cell switch that determines how long Ozempic’s weight-loss effects last. Researchers at the National Institutes of Health (NIH) have gained new insight into how GLP-1 receptor agonists such as semaglutide produce their weight-loss effects. While scientists have long known which areas of the brain are involved, much less has been [...]
