Research finds ovarian hormones play genes like a fiddle

A complex relationship between genes, hormones and social factors can lead to eating disorders in women. Kelly Klump, Michigan State University eating disorder expert, has made monumental strides in deciphering how these factors interact. In her latest discovery, she has found that during the menstrual cycle, ovarian hormones act like a master conductor – they turn genetic risk on and off in the body.

Research links impulsivity and binge eating

Do you get impulsive when you’re upset? If so, this could be putting you at risk for binge eating.

According to Kelly Klump, professor of psychology at Michigan State University and senior author, the more impulsive you are, the more likely it is you’ll binge eat when experiencing negative feelings.  

Season's eatings

‘Tis the season of plenty of food and drink.  While celebrating should be joyful, for some women, it’s not. All the holiday temptations can add another layer to an already complicated biological process.

It’s well known that women undergo hormonal changes every month due to the menstrual cycle. These changes can cause women to eat more, which is a natural, biological occurrence. 

However, Michigan State University Foundation Professor Kelly Klump has found that the increased food intake causes some women to become much more preoccupied with their body weight and shape. This intensified obsession can increase the risk of developing eating disorder symptoms.  


Two strains of rats, cans of vanilla frosting and a theory have helped MSU professor of psychology Kelly Klump take one step closer to finding the genetic causes, and eventually a treatment, for binge eating.

In her latest research, Klump decided to use rats to help identify different biological and genetic factors that contribute to binge eating.
