HUNGER HORMONES MAY HOLD KEY TO OBESITYScientists are predicting that weight could be controlled in the future with hormone treatment. American researchers have identified hormones in the brain they claim are responsible for controlling appetite. By manipulating the levels of two chemicals they believe eating could be inhibited, providing a direct means of controlling weight and eating disorders.Scientists at the university of Texas Southwestern Medical Center, Dallas, conducted experiments on laboratory rats in which the hormones, orexin-A and orexin-B, were applied to the brains. The results showed the chemicals stimulated the rats' appetites, promoting them to eat more food then previously. When food intake was limited the rats were found to produce more of the hormones as they became hungrier. Tests are now under way to see if the rats' appetite can be decreased by inhibiting the hormone. --> return to menu / back ... (click) --> return to top of the page (click) |
