One of the oft-overlooked perks of getting into a relationship is that you can finally stop dieting and going to the gym so much.

Four out of five people gain what's called "love weight" when they get into a serious relationship. A new survey figured out a few reasons why it happens:

  • Eating out more.
  • Adopting a less active lifestyle.
  • Staying home to eat and drink.
  • Exercising less to spend more time together.
  • Trying new foods and restaurants as a couple.
  • Starting a family.
  • Less motivation to keep up your physique.
  • Take more Ubers or taxis together instead of walking places.
