A recent study of over 15,000 Australians has found that people in relationships are more likely to put on weight than those who are single.
Surprisingly thought the study found that couples actually ate a higher quantity of fruit and vegetables and didn't smoke, drink too much alcohol and avoided eating fast food.
The researchers put the weight gain down to a reduced amount of exercise, the effects of having children and they also suspect that those in relationships feel less pressure to look good for their partner.
"When couples don’t need to look attractive and slim to attract partner, they may feel more comfortable in eating more, or eating more foods high in fat and sugar." the researchers said.
So even though there are lots of up sides to being in a relationship, if this study is anything to go by, there are also some obvious downsides too!
