On top of what you already know as love can do, just add that it can make a couple gain weight.
A recently published research at the University of North Carolina, a happy couple have what it takes to add weight, and it happens exactly that.
The research involved putting under study more that 8000 people and found out that at least years in happy marriage can give a woman 10.8 kgs more weight.
Women who are not married but lived with their partners gained about 11kg and women who left their partners had gained less than 7kg.
For men, weight comes when they are exiting single hood. In relationship that has been sustained for long, weight gaining was found to be just inevitable.
In a related research, newly married couples take little time to gain weight where the addition of weight is a positive parameter for happiness in marriage.
According to another study published by the New England Journal of Medicine, weight gain by one partner directly affects the other to gain weight by 37%.
To put the study in context, social environment and the habits of couples were founds as the surrounding factors of weight gain among couples. Spending time together for happy couples was a precursor for gain weight which is rare for unhappy couples.
