There is new evidence that the happier you are in your marriage, the more likely it is that you will gain some extra weight.
Researchers followed 169 newlywed couples for four years.
They found spouses who are more satisfied tend to gain more weight, and spouses who are less satisfied tend to gain less weight.
The lead researcher, Andrea Meltzer, an assistant professor of psychology and a social psychologist at Southern Methodist University, in Dallas says, "What is less clear is the role of marital satisfaction in marital weight gain."
She also stressed that the association doesn't prove a cause-and-effect link.
