Weight gain is not always linked to stress, according to new research. Researchers in London reviewed three dozen previously published studies on the relationship between stress and weight gain.

In the review published in the journal "Obesity," researchers found no link in 69 percent of those studies.

Most participants in the studies were followed between one and seven years.
