Fad diets and extreme eating plans pose various dangers, including potential nutritional deficiencies due to restricted food groups. Such diets can lead to imbalances in essential vitamins and minerals, affecting overall health and vitality. Furthermore, the rapid weight loss often associated with these plans can result in a yo-yo effect, wherein individuals regain the weight quickly after returning to normal eating patterns. This cycle can foster an unhealthy relationship with food and body image, leading to disordered eating behaviors. Sustainable weight loss is more effectively achieved through balanced nutrition and lifestyle changes.
