This "perfect diet" is linked to bad moods and emotional slumps

New research reveals that cutting calories may lead to mood swings and depression, especially in men and overweight individuals.

Dieting may worsen emotional health and lead to depression

Many people believe that cutting calories will improve their mood and help with weight loss. However, recent research indicates that restrictive diets could actually contribute to higher levels of depression, particularly among men and those who are overweight. A U.S. survey analyzed the eating habits of 28,525 adults and found that those who limited their calorie intake reported higher scores for depressive symptoms on the PHQ-9 questionnaire. The study, led by Dr. Gabriella Menniti from the University of Toronto, highlighted that men who count calories often face greater risks of mood issues, likely due to their differing nutritional needs.

Key Takeaways

✔️

Calorie-restricted diets may lead to increased mood swings and depression.

✔️

Men appear to be more affected by dieting in terms of mental health.

✔️

Overweight individuals cutting calories risk deficiencies in critical nutrients.

✔️

Low energy and mood swings can complicate adherence to weight loss plans.

✔️

A balanced diet may support better mental health and weight management.

✔️

Tracking mood alongside meals can reveal patterns related to diet.

"Diets low in carbohydrates or fats may worsen brain function."

Dr. Menniti suggests that restrictive diets can negatively impact brain health and mood.

"Men who count calories report higher somatic complaints like fatigue."

This shows that dieting may affect men's energy and overall well-being more than women's.

"Cutting calories may create a loop where weight barely shifts but nutrient levels tumble."

This points to a potential reason why dieters often struggle with their goals.

"Food is information, not just fuel. Mindful tweaks can signal the body positively."

This emphasizes the need for a balanced and thoughtful approach to eating.

The findings of this study raise important questions about the effectiveness of traditional dieting methods. While many seek to lose weight by cutting calories, this research suggests that the emotional toll may outweigh potential benefits. Cutting calories often results in nutrient deficiencies that can lead to irritability and fatigue. This might explain why many individuals struggle to stick to their diets and may even gain weight back after initial losses. It seems that instead of pursuing restrictive diets, a more balanced approach to nutrition that prioritizes overall well-being could be more effective in the long run.
