As an undergraduate student in Perth, Amanda’s inability to lose weight prompted her to start a career in medical research so she could find a solution. She’s since lost 28 kilos and has kept it off for over 10 years. During her PhD at the University of Geneva, Amanda discovered pathways by which a natural brain chemical called neuropeptide Y inhibits weight loss in times of scarcity. Since joining the Garvan Institute in 1998, Amanda’s team has made major inroads to understanding how neuropeptide Y interacts with other natural chemicals in the brain to bring on the ‘famine reaction’, the survival mechanism that prevents many people from losing excess weight.
 
 
 

The aim of Amanda’s current research is to find ways to block neuropeptide Y and other mediators of the famine reaction so that more people can attain and maintain a healthy body weight.

Why women should eat less, move more and consider wearing transdermal patches during menopause

MEDIA RELEASE: 24 Nov 2008
Weight and appetite experts from around the world met at a conference in Bangkok earlier this year to discuss sex differences in obesity. One line of discussion looked at factors leading to women’s weight gain during menopause, and how it might be avoided.
 
 

Glimpse the future of medical research at Garvan Open Day

MEDIA RELEASE: 18 Jul 2008
Garvan will open its doors on Sunday 17th August from 10am to 1pm for Open Day, giving the public the opportunity to meet and talk with leading scientists and learn about the future of science and medicine from some of the sharpest minds in Australia.
 
 

Natural gut hormones may provide a treatment for obesity

MEDIA RELEASE: 08 Jan 2008
Garvan researchers have shown that a hormone released naturally from the gut could be used to treat obesity and Type 2 diabetes. After a meal, the hormone peptide YY (PYY) is released from the gut and acts on the brain, contributing to a feeling of satiety. Researchers foresee the use of this hormone as a weight loss medication.
