You know the look- older people who look anorexic yet feel fine. Is there something about growing older that leads to such weight loss in basically healthy people? Apparently so, at least according to researchers in the United Kingdom. Appearing in the journal Appetite, a new study suggests that production of peptide YY, a hormone that signals to your body that you are full, increases as you age. So it may be that the 15-20% of seniors who experience a loss of appetite and unintentional weight loss are responding to this hormone increase. Further research needs to confirm these findings but it’s possible this study will lead to new therapeutic approaches for these seemingly anorexic elders. Want more info on this new research?
