“Loss of appetite can be an early sign of depression or a warning of a depression relapse. On the other hand, some people can’t stop eating when they are depressed,” says Gary Kennedy, MD, director of geriatric psychiatry at Montefiore Medical Center in Bronx, New York. “A sudden change in weight, either gaining or losing, can be a warning of depression, especially in someone who has other symptoms of depression or a history of depression.” How Depression Affects Appetite Changes in your eating habits may be related to other symptoms of depression, such as fatigue and a lack of pleasure from activities. “Many people with depression lose both energy and interest. This can include a loss of interest in eating.” says Dr. Kennedy. “This may be especially true for older people with depression, who may lose interest in cooking and don’t have the energy to prepare meals. For others, nausea may be a symptom of their depression and a cause for loss of appetite.” While loss of appetite is a common depression symptom, feelings of sadness or worthlessness can make some people overeat. “Depression can also result in emotional eating, a common event in which the need to eat is not associated with physical hunger,” says Debra J. Johnston, RD, culinary services manager at Remuda Ranch, an eating disorder treatment center in Wickenburg, Ariz. “Instead, emotional eating is eating in response to emotional hunger. When patients eat in response to their emotions, they are soothed by the food as it changes the chemical balance in the brain, produces a feeling of fullness that is more comfortable than an empty stomach, and improves mood through positive association with happier times.” When Should You Talk to a Doctor?

Here are warning signs you should tell your doctor about:

Maintaining a Healthy Diet for Depression Trying to stick to your regular eating habits as well as eating a healthy diet may help you manage depression. “There is no depression diet that will cure or prevent clinical depression, but there is research to show that some diets are better than others for depression,” says Kennedy. These nutrition tips may help:

These substances are found in cold-water fish and have been shown to be important in brain function. Some studies show that they may enhance a person’s response to antidepressant medications.Vitamins and nutrients. “Research shows that deficiency of nutrients such as vitamin B12, vitamin B6, and tryptophan can have a negative effect on mood. Consequently, poor nutrition that results from loss of appetite can further exacerbate depression,” explains Johnston.Nutritional support. You may want to talk to a dietitian about your eating habits. “A dietitian can help someone with depression by creating a nutritionally balanced meal plan that takes into account the patient’s individual needs,” says Johnston. “For example, the depressed patient may not have the energy or desire to prepare a meal. The dietitian will consider this and create menus that utilize easy-to-prepare foods.” People with severe depression who experience a loss of appetite may need nutritional supplements to help prevent weight loss and nutrient deficiency.
