Does Having Bad Memory Impact Weight?

Bad memory might impact a person's weight because not remembering how much one recently ate could make the brain trigger feelings of hunger, according to a 2013 study. For example, participants with amnesia that caused short-term memory loss would report feeling hungry not long after meals because they had forgotten about the previous meal. Researchers believe that people who are able to eat properly sized portions are those whose food memories and stomachs are synchronized — they can remember more accurately their recent meals or snacks and can refer back to them. Another 2013 study found that women who lost weight reported improvements in cognition, which might suggest that obesity itself contributes to bad memory.
