Did Scientists Just Discover Why Some Old People Get So Skinny?


These obvious signs of aging happen for a multitude of reasons.

For instance, skin begins to wrinkle as it begins to lose elastin and collagen. Eyesight also begins to fade as your eyes’ lenses begin to harden; the nerves in your eyes begin to operate out of whack, and musculature ceases to perform at the same level. 


Approximately 15-20% of seniors lose weight when they experience a condition known as “anorexia of aging.” The exact causes for this unintentional weight loss are yet to be determined.



According to researchers at Plymouth University in the United Kingdom, a possible reason so many elderly people waste away is because they always feel full…even if they haven’t eaten for some time.


And really, why would you want to eat if you felt full?







Here’s what the researchers found:

“The researchers measured their levels of PYY, ghrelin, and glucagon-like peptide 1 (GLP-1) – a hormone that is responsible for reduced appetite and the release of insulin – at regular time intervals over a 3-hour period.



When the subjects with high levels of PYY were asked about their next meal, they reported they didn’t really enjoy eating it and they therefore decided to reduce how much they ate after their first meal.


Further testing in PYY levels and weight loss needs to be conducted, but I would hazard a guess they’re going to conclude with similar results.

Do findings like this surprise you at all?
