There are ~obvs~ so many great benefits of being in a relationship. There's someone to cuddle at night, share your thoughts with and give you company...
...but there is a downside, apparently.
According to a new study conducted at the University of Queensland in Australia, that old wives' tale that being in a relationship makes you put on weight is all too true.
In the extensive study, researchers analysed a decade's worth of data from over 15,000 people and found that couples in happy relationships weighed an average of 5.8kg more than their single counterparts.
What's more, they also discovered that those coupled-up had an average weight gain of 1.8kg per year.
"Marriage (or de-facto relationships) comes with spousal obligations such as regular family meals," the researchers said.
"While they may include more healthy foods such as fruits and vegetables and less fast food, people often consume larger portion sizes and more calories in the company of others than they do alone, resulting in increased energy intake."
The study continued to explain: "Marriage and cohabiting also carry the potential for encouraging unhealthy behaviours, as couples often perform behaviours like eating, watching TV, and drinking alcohol together," state the findings.
Lead author Dr Stephanie Schoeppe told New Scientist magazine: "When couples don't need to look attractive and slim to attract a partner, they may feel more comfortable in eating more, or eating more foods high in fat and sugar."
