With the holiday season in full swing, a new study was released that found a correlation between a positive mood and weight loss in women.
The research was published in the November/December issue of the journal General Hospital Psychiatry, and looked at 203 women between the ages of 40 and 65 who had an average Body Mass Index of 38.3.
The women were separated into two groups that both focused on weight loss. However, one also monitored the participants' depression levels during the study period.
After six months, it was found that among women whose depression score on the Hopkins Symptom Checklist decreased by half a point, a total of 38 percent had lost 5 percent of their body weight.
Lead author Gregory Simon, M.D., of Group Health Research Institute in Seattle, explained that he expected a "relationship" between depression and exercise, but that the nature of the relationship was still unclear.
"We see in our study that they go together, but we can't say which causes which," Simon said.
One possibility could be the diet itself. Earlier this year, a study published in The British Journal of Psychiatry found that people who ate junk food were more likely to suffer from depression.
