They studied over 10,000 people and found that married people weigh almost 5 pounds more than single people.  But not because they eat poorly, married people actually eat healthier than single people.

So why do married people weigh more than single folks?  This study came to the conclusion that it is because married people don't exercise as much as single people.

It's not because they are happier than single people, it's simply a lack of exercise.
