Killer Carbs: Scientist Finds Key To Overeating As We Age:
"A Monash University scientist has discovered key appetite control cells in the human brain degenerate over time, causing increased hunger and potentially weight-gain as we grow older. The research by Dr Zane Andrews, a neuroendocrinologist with Monash University's Department of Physiology, has been published in Nature.
Dr Andrews found that appetite-suppressing cells are attacked by free radicals after eating and said the degeneration is more significant following meals rich in carbohydrates and sugars.
'The more carbs and sugars you eat, the more your appetite-control cells are damaged, and potentially you consume more,' Dr Andrews said."
