Nutritional Deficiencies in Low-Calorie Diets Fuel Depression Risks According to Dr. Venkat Bhat's Study
Published on 6.14.25
A growing body of research suggests that low-calorie diets may have a detrimental effect on mental health, particularly in individuals experiencing weight-related stress. According to Dr. Venkat Bhat, lead author of a recent study, restrictive or unbalanced diets can trigger depressive symptoms due to potential nutritional deficiencies in key proteins and vitamins essential for brain function and mood regulation.
A Mediterranean-style diet, rich in fruits, vegetables, whole grains, and healthy fats, has been shown to have the opposite effect. This type of diet is associated with fewer mental health issues and improved overall well-being. In contrast, diets high in ultraprocessed foods, refined carbohydrates, and processed meats are linked to greater depression symptoms.
The study found that individuals following low-calorie diets may experience higher depressive symptoms due to potential nutritional deficiencies in key proteins and vitamins essential for brain function and mood regulation. Dr. Bhat warns against overly restrictive or unbalanced diets, especially for those experiencing weight-related stress.
A steady stream of glucose and omega-3 fatty acids are crucial for maintaining healthy brain function, which can be compromised by restrictive dieting. The findings highlight the importance of personalized guidance when it comes to weight loss. Rather than adopting extreme calorie restriction, individuals should focus on developing a healthful eating pattern that includes essential nutrients like omega-3 fatty acids and vitamin B12. By doing so, they can reduce their risk of depressive symptoms and maintain overall well-being.
