Depression can make healthy food unappetizing until only junk food and chocolate seem attractive. If junk food is all you can get yourself to eat, you may experience excessive weight gain. Do not worry; your appetite for healthy food will return with depression treatment.
When your weight is changing, it is hard to know how much is too much. The American Psychiatric Association criteria suggest that loss or gain of more than 5 percent of your natural body weight may be caused by unipolar major depression. Your doctor can tell you more.
