Breaking news: When you don’t have to worry about finding people to have sex with, you start eating more cupcakes.

A new study in Switzerland just proved something your tight pants have been telling you for a long, long time: Getting married makes you chubby.

Researchers studied more than 10,000 people, and found that married people weigh an average of four-and-a-half pounds more than single people.

Here’s the strange part: They’re putting on that weight even though they’re eating healthier. Married people are more likely to eat organic food, unprocessed foods, and fruits and vegetables than single people.

But they also exercise a lot less. Obviously that makes you gain weight over time — even though you’re eating better food.
