VICTORA, AU─ Hunger and weight gain may increase as people age, because key appetite control cells in the brain degenerate over time, a university scientist discovered.
The research, published in Nature, found that the more carbs and sugars one consumes, the more their appetite control cells are damaged. Thus, study author Dr. Zane Andrews said, the attack on appetite-suppressing cells creates a cellular imbalance between the need to eat and the message to stop.
Those most at risk are 25 to 50 year-olds, Andrews said.
Andrews said these findings could be one explanation for adult-onset obesity.
