Researchers issue alert on potential risks associated with excessive weight reduction
Article Rewrite:
Apparently, research conducted by University of Toronto scientists and published in the journal BMJ Nutrition Prevention & Health presents an unexpected link between strict low-calorie diets and depression or emotional distress.
The study analyzed data from 28,000 Americans participating in the National Health and Nutrition Examination Survey. Participants were classified according to their diet patterns. The outcomes indicated a higher likelihood of depression and emotional disturbances among those adhering to stringent low-calorie diets, especially men and those carrying excess weight.
Strict diets were also tied to a decline in cognitive-affective functions. People on these diets reported poor mood, negative thoughts, anxiety, and internal tension. The absence of fats and carbohydrates often led to physical symptoms such as restlessness, fatigue, and irritability.
These findings conflict with earlier studies suggesting improved mental health with low-calorie diets. The difference, according to the researchers, is attributable to the controlled environment and carefully balanced diets in those previous experiments. However, in the real world, such diets may result in nutritional deficiencies that negatively impact mental health.

Insights into the Study:
- Nutritional Deficiencies: Real-life diets often result in nutritional deficiencies due to imbalanced diets or lack of essential nutrients. These deficiencies can lead to stress and depressive symptoms.
- Stress and Psychological Factors: The stress of following a restrictive diet, combined with potential weight cycling, can increase feelings of frustration and depression.
- Diverse Eating Habits: Real-world diets can be highly variable, often not aligning with the idealized diets used in controlled research.
- Controlled Environments: Research conducted under medical supervision typically ensures balanced diets and adequate nutrient intake, reducing the risk of deficiencies observed in real-life restrictive diets.
Overall, while low-calorie diets may be beneficial under controlled conditions, their application in real-world scenarios can lead to psychological stress, potentially resulting in depression due to nutritional deficiencies and other factors.
- I must be mindful of my health-and-wellness, considering the study that links strict low-calorie diets to an increased likelihood of depression, emotional distress, and nutritional deficiencies.
- In light of this research, I am encouraged to focus on maintaining a balanced diet for my mental health, including sufficient nutrition to avoid any potential effects on my mental-health and cognitive-affective functions.
