Yo-yo dieting, a common practice among the British population, has been linked to an increased risk of depression. A recent study published in BMJ Nutrition Prevention & Health found that individuals who restrict their calorie intake are more likely to experience depressive symptoms, including low mood, low energy, and sleep disturbances.
Experts suggest that extreme calorie restriction can have far-reaching consequences, including impaired sleep, concentration, and physical health, potentially exacerbating depression. They recommend personalized guidance to support mild to moderate caloric restriction through a balanced eating pattern.
Research supports this narrative, indicating 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. A steady supply of glucose and omega-3 fatty acids is crucial for maintaining healthy brain function, which can be compromised by restrictive dieting.
