Can Depression Make You Lose Weight?
Depression and Weight Change: An Overview
Depression is a complex mental health condition that can significantly impact various aspects of an individual's life, including their weight. Research indicates that depression can lead to both weight loss and weight gain, depending on various factors such as the severity of depression, individual eating behaviors, and physical activity levels.
Weight Loss in Depressed Individuals
Several studies have shown that depression can indeed lead to weight loss. For instance, a study examining weight changes in 109 outpatients with depression found that 30% of the patients experienced weight loss during their depressive episodes2. This weight loss was often rapid and was significantly correlated with the severity of depression as measured by the Hamilton Rating Scale for Depression (HRSD)2.
Another study focusing on women with co-occurring obesity and depression found that those who experienced a decrease in depression scores were more likely to lose significant weight (5 kg or more) within the first six months of a behavioral weight loss program1. This suggests that improvements in mood can be associated with weight loss, potentially due to increased physical activity rather than changes in caloric intake1.
Mechanisms Behind Weight Loss
The mechanisms behind weight loss in depressed individuals can be multifaceted. Depression can lead to a decrease in appetite and a lack of interest in food, which can result in reduced caloric intake and subsequent weight loss9. Additionally, the psychological and physiological stress associated with depression can affect metabolic processes, further contributing to weight loss10.
Bidirectional Relationship Between Depression and Weight
The relationship between depression and weight is bidirectional. While depression can lead to weight loss, it can also result in weight gain in some individuals. A meta-analysis of longitudinal studies found that depressed individuals are at a higher risk of developing obesity over time, particularly adolescent females7. This highlights the complex interplay between mood disorders and weight changes.
Weight Loss Interventions and Depression
Interestingly, weight loss interventions can also impact depressive symptoms. A systematic review and meta-analysis found that lifestyle modification programs, which include diet and exercise, were effective in reducing symptoms of depression in obese individuals4. These findings suggest that intentional weight loss through structured programs can have a positive effect on mood, potentially creating a beneficial cycle of weight loss and improved mental health4 6.
Conclusion
In summary, depression can indeed lead to weight loss, particularly in individuals who experience severe depressive symptoms. The relationship between depression and weight is complex and bidirectional, with some individuals gaining weight while others lose it. Weight loss interventions that include lifestyle modifications can help improve depressive symptoms, highlighting the importance of integrated treatment approaches for individuals with co-occurring depression and obesity.

Association between change in depression and change in weight among women enrolled in weight loss treatment.
Short-term improvement in depression is associated with weight loss in women enrolled in behavioral weight loss programs.
Non-RCTWeight change in depression
Depression can lead to weight gain, weight loss, or no change in weight, with weight loss occurring more rapidly than weight gain.

Intentional weight loss in overweight/obese individuals with type 2 diabetes does not precipitate depression symptoms, and mild symptoms of depression at baseline do not prevent significant weight loss after 1 year.

Depression does not reduce the effectiveness of behavioral weight loss treatment for obese women over 40 years of age, suggesting that it should not be an exclusion criterion for such programs.
