Have you ever wondered why you always seem to have such a hard time eating healthy? Well, according to researchers at Deakin University, it may have something to do with your personality. In their study published in the journal Nutrition, they explain that those with “open” and “conscientious” personalities are more likely to eat more fruits and vegetables and say no to unhealthy eating habits compared with their peers.

However, this doesn’t necessarily mean that you're doomed to suffer junk food binges and crash diets forever. Michael Mantell, senior fitness consultant for behavioral sciences for the American Council on Exercise, says that while being open and conscientious does help push people to become more disciplined eaters, there is no long-term association, reports Prevention.com.

This means you can use those existing traits or strive to develop them to help you get into the habit. At the end of the day, you have the final say on what you put in your mouth.
