Researcher Sora Shin, an assistant professor at the Fralin Biomedical Research Institute at Virginia Tech has discovered a molecule that triggers the need to eat high fat foods in mice 24 hours after being exposed stress in the form of the scent of cats.

This molecule is found in the hypothalamus section of the brain which is the part of the brain that is connected to changes in the brain that lead to emotional overeating.

 The same molecule is found in people as well as animals. This discovery may lead to treatment methods that can help people who react to the emotionally driven need to overeat, even when they are not hungry.

Sue’s Note: There are many animals, particularly dogs and cats that tend to overeat which result in them becoming obese. Pet owners who have pets that have this problem should consider stress as a factor that causes their pets to overeat. First be sure that the family or friends are not over feeding the pets. If this is not the case the pet owner should evaluate the possibility that stress may be a cause. Since the study showed that the effects of stress can cause overeating 24 hours later, the pet owner should consider events that happened in the last 24 hours. An example would be someone or something that passes the pet’s home when the owner is not home that causes high stress in the pet. In situations where stress is a factor, reducing the amount of food that the pet has access to may cause a greater amount of stress. In this case over the counter calming remedies may help the pet. If not a visit to your veterinarian would be in order explaining to the veterinarian that you suspect stress is a cause of the overeating.
