Do friends describe you as spontaneous and impulsive? Or are you more calculated and predictable? 
According to a new study published in the Journal of Personality and Social Psychology, your answers could impact the number you see on the scale.

After examining 50 years of data, researchers found that people who are high on neuroticism and low on conscientiousness are likely to go through cycles of gaining and losing weight throughout their lives.

In fact, impulsivity was the strongest predictor of who would be overweight (those who were on the impulsive end weighed an average of 22 pounds more than those who were more conscientious).

The theory: People who are impulsive tend to give in to temptation and lack the discipline to stay on track. After all, maintaining a healthy weight usually requires following a healthy diet and getting regular exercise -- a tall order for those of us who are a little rash.
 
If you're impulsive, don't give up just yet. We've got a few tips on how you can keep your weight in check.

-    Plan ahead. Prepare for unknown cravings by tucking easily portable snacks like granola bars, string cheese or pre-measured baggies of trail mix in your purse, backpack or briefcase. If a hectic schedule routinely makes it hard for you to make a healthy meal, collect menus from your favorite take-out restaurants and identify a few balanced choices in advance, before you're ravenous.

-    Get a buddy. If someone expects you at the gym, it's not as easy to stay in bed. And don't underestimate the power of true confessions. Knowing you'll have to come clean to your buddy about indulgent bouts of mindless eating may make you think twice before hitting the fridge.

-    Watch the liquid courage. Calories from alcohol add up fast. A buzz kill, yes, but you'll thank us later. Alcohol stimulates appetite and lowers inhibitions, and makes impulsive folks, well, a little more impulsive. So indulge in a virgin Mojito or sip on club soda with a little OJ. Still jonesing for a "real" drink? Make sure you imbibe with food. That slows the entry of alcohol into the bloodstream and helps you recognize when you're full.
