Fad diets can pose several dangers to overall body health. They often promote extreme restrictions that can lead to nutrient deficiencies, adversely affecting metabolism and overall well-being. Many fad diets rely on unsustainable methods, leading to quick weight loss, but frequently result in yo-yo dieting, which can harm long-term health. Additionally, these diets may encourage unhealthy eating patterns and misconceptions about food. Instead of fostering healthy habits, they can create a negative relationship with food and body image, ultimately jeopardizing both physical and mental health.
