Arguing with your partner can not only be bad for your relationship but also your waistline, a new study claims.
Having a row was linked to an appetite-triggering hormone which can make us head straight for the fridge, researchers found.
The study's authors at Ohio Sate University discovered that hostile exchanges were often followed by a surge in the 'hungry hormone' ghrelin, which could lead to binging on junk food.
But the study found that the hunger pangs only affect people who are of a healthy weight or overweight, not obese, reports the Daily Mail.
Correlation between marital distress and poor food choices
For the study, couples ate a meal together before trying to resolve one or more conflicts in their relationship.
They then completed questionnaires about themselves and had samples of blood and saliva taken. This was so levels of a key stress-related hormone and numbers of certain immune cells could be tested.
But they said there was nothing to suggest the arguments had caused hunger, but that there was a strong correlation between the two.
Previous studies have found hungry people are more likely to lose their temper because when we haven't eaten enough, our brain lacks the energy needed to exercise self-control.
It is hoped the latest research will lead to a greater understanding of the link between marital difficulties and health problems.
