So what's the biggest cause of those extra pounds? Sixty-four per cent of respondents said they no longer felt pressure to look their best to attract a mate. Eating out frequently is another culprit for weight gain, according to 41 per cent of those surveyed. And 34 per cent of people blamed take out and drinking at home for the uptick in pounds.
This isn't the first time studies have shown that dating derails dieting. Earlier this year, researchers from the University of Queensland found that couples have higher BMIs than singletons, despite eating healthier and being more active, Mens Health US reported. People in relationships typically spend more time eating together, watching TV, and drinking alcohol. Even though many couples eat healthy food, their portions tend to be larger.
Of course, snagging a mate doesn't need to kill your healthy habits. Instead of vegging with pizza and wine, try hitting the gym together. Researchers at Santa Clara University found that working out with a partner makes people feel more energetic and happier than working out solo.
