Aww true love. All the songs on the radio are about you, you feel all warm and fuzzy inside ...and you’ve gained weight?!
It is bad news for everyone but the commitment –phobic I’m afraid. A study published in the Obesity Medical Journal found that those who co-inhabit are more likely to gain weight then their single counterparts. It gets worse if you are married. Those who are married double their chances of becoming obese.
The reasons for this are adopting your partners eating habits and portion sizes, eating out more often and prioritising differently (the gym falls way down on the list).
The good news is that couples who decide to lose weight and eat healthier tend to be more successful than their single counterparts if they diet together.
