Calorie Restrictive Diets Could Cause Worsening Depression, New Study Says

Low-Calorie Diets Linked to Depression, According to Recent Study

A new study suggests that low-calorie diets could be linked to worsening depression symptoms. The research, which was published in the journal BMJ Nutrition, Prevention & Health on Tuesday, June 3, analysed data from over 28,500 adults regarding their diets and depressive symptoms.

Contrary to previous findings that suggested low-calorie diets could improve depressive symptoms, this study revealed a different outcome. It found that individuals following calorie-restrictive diets experienced more significant mood changes, particularly among men and overweight individuals.

The participants in the study completed a health questionnaire focusing on depressive symptoms, which were then used to assess the severity of their conditions. The researchers discovered that a notable percentage of participants reported experiencing depressive symptoms, with a significant portion of them being overweight or obese.

Interestingly, the study highlighted that while many individuals in the study were not following a specific diet, a considerable number were restricting calories, following regimented diets for health conditions like diabetes, or limiting certain nutrients like fat, sugar, or carbohydrates.

Moreover, the research found a prevalence of low-calorie diets among obese and overweight participants. Those on restrictive calorie diets reported higher levels of depressive symptoms such as low mood, fatigue, and sleep disturbances compared to those not on a diet.

The study emphasised the importance of considering real-world eating habits, as opposed to focusing solely on healthy versus unhealthy diets. It pointed out that caloric restriction could lead to deficiencies in essential nutrients like protein, vitamins, and minerals, which could contribute to increased stress on the body.

Despite the significant findings, the researchers acknowledged some limitations to the study. However, they underscored the importance of understanding how these types of diets may impact depression, especially in men and individuals struggling with obesity.

Professor Sumantra Ray, the chief scientist and executive director of the NNEdPro Global Institute for Food, Nutrition and Health, highlighted the need for further well-designed studies to delve deeper into this topic. While the study revealed small effect sizes, more research is required to accurately capture dietary patterns and potential confounding factors.

In conclusion, the study sheds light on a potential link between low-calorie diets and depression symptoms. It serves as a reminder to consider the holistic impact of dietary choices on mental health and well-being. More research in this area could provide valuable insights into better understanding and addressing depression in various populations.
