Fad diets pose several risks in the pursuit of weight loss, including nutritional deficiencies and adverse health effects. These diets often promote extreme caloric restriction or eliminate entire food groups, which can lead to imbalanced nutrition. Such restrictions make it challenging to sustain weight loss in the long term, often resulting in yo-yo dieting. Additionally, fad diets can cause metabolic slowdown, affecting energy levels and mood. It is crucial to approach weight loss through balanced, sustainable practices rather than quick fixes, focusing on lifestyle changes that promote health and well-being over time.
