Do you comfort eat when you are blue?

New research has found hormones in people with depression could be making them gain weight

A team of researchers at the 51²è¹Ý (UOW) and the (IHMRI) has found that people who are depressed are at higher risk of weight gain.

Gaining weight puts them at risk of other health problems later in life including heart
disease and metabolic syndrome.
Comfort eating is often believed to be the cause of expanding waist lines in people with depression, but how or why food is used to help cope with stress or sadness is unclear.

“Our study investigated several pathways that might be related to comfort eating in depression. We measured weight, body mass index (BMI), depression symptoms and eating behaviours as well as hormones,” said PhD candidate Jessica Mills.

The team of researchers also includes, Dr , Professor and Dr .

The team measured appetite hormones including grehlin, which should stimulate appetite and leptin, which should reduce feelings of hunger.

For people suffering depression the research suggests they may experience hormonal dysregulation.

Early findings suggest excessive eating may be linked to an insensitivity to hormonal signals, by which the usual signals of being hungry or full are not being received properly.

“The results showed comfort eating was more common in people with depression than those without, and was more common in females than males,“ Jessica Mills said.

“This indicates that excessive eating in depression may be more closely related to hormones than previously realised, rather than just being related to psychological issues.”

A new, larger study is soon to get underway in the Illawarra which will follow participants over a period of 12 months. It is hoped this trial will help determine which comes first – do hormones caused the comfort eating or does comfort eating affect the hormones?

The study is published in the journal .

The team has also published a study on similar work in the  last year.
