Low-Calorie Diets and Their Potential Impact on Mental Health

Low-Calorie Diets and Mental Health

Low-calorie diets are often promoted for weight loss, but recent research suggests they may have adverse effects on mental health, especially in men. A study led by researchers from Toronto analyzed data from over 28,000 adults to explore the relationship between dieting patterns and depressive symptoms. Findings indicated that participants restricting calories exhibited higher levels of depression, with overweight men showing the most significant association.

The study categorized individuals into groups based on their diets: calorie-restricted, nutrient-restricted, established medical diets (like DASH), and no diet. Results showed that calorie-restricted dieters had higher depression scores, especially those with higher BMI. In men, all dietary patterns correlated with increased somatic symptoms, emphasizing the potential mental health risks associated with restrictive dieting.

Experts like dietitian Amy Roethler and neuronutritionist Timothy Frie discussed the implications, highlighting that calorie restriction, particularly without adequate nutritional support, can impair neurochemical processes essential for mood regulation. The researchers aim to further investigate specific nutritional deficits linked to dieting that may contribute to depressive symptoms.

This study underscores the importance of balanced, nutrient-rich diets and cautious weight management strategies to support mental health.
