Is your depression keeping you from losing weight?

By Dr. Micaela Wexler
If you are having trouble losing weight, it could be due to depression. As a family psychiatrist, this link is very obvious to me, but not to my patients. Studies show that depression and obesity are linked to each other. A meta analysis study published in JAMA in March 2010 shows a that depression can lead to obesity and obesity can lead to depression. (1) A study of Dutch teenagers, published in Obesity in March 2010, showed a clear association between weight status and suicidal behavior in obese adolescents. (2) The same link was found in a later study done on Korean teenagers. (3)
Depression causes physical changes which affect interest, sleep, appetite, sexual drive, and thought processes. Some types of depression cause people to eat and sleep more than normal. If you are having trouble finding the willpower to exercise it might be due to decreased motivation, which might be due to depression.

Are you finding it hard to lose weight even though you are exercising and sticking to your diet? This could also be due to depression because depression makes the body’s metabolism change. When a person is depressed chemical changes take place that make it harder to lose weight. Some of these changes can cause weight gain and fatigue.

Depression can also cause a change in eating patterns. The chemical imbalances caused by depression make it harder for people to connect hunger with food intake, which is why some depressed people eat even when they are not hungry. Or, they are hungry even after eating.

It is easy to blame your weight on lack of willpower. But, if you are having trouble losing weight, it is important to make sure you are not depressed. Besides causing weight gain, untreated depression can cause more serious problems like diabetes, heart disease, and suicide. And, studies show that treating depression leads to weight loss.

Do you feel sad or hopeless? Are you having trouble sleeping? Have you lost interest in things like hobbies or TV shows or fun activities? Do you have trouble motivating yourself to do things? Are you short-tempered? Do you have negative thoughts about yourself? All of these are signs that you might be depressed.

If you’re having any of these signs, go see a therapist or a doctor or call your local mental health center. Start treating your depression so it doesn’t keep you from losing weight.
