It sure is easier to eat that fifth slice of pie when you know your sex life doesn't depend on impressing strangers anymore.
According to a new study, the number one cause of weight gain is being in a relationship.
Going on vacation came in second, and trying to comfort yourself after a break-up came in third.
The study found 62% of people say they've gained at least 14 pounds since they got into a committed relationship.
And three out of four people said their significant other ALSO gained weight since they got together.
The study also found about half of couples burp in front of each other, 25% pass gas in front of each other, and 25% of women shave their legs and armpits less often.
