Extreme dieting poses various risks, including severe nutritional deficiencies that can lead to health complications such as weak bones, hair loss, and a weakened immune system. It can also cause metabolic slowdown, where the body adapts to the low calorie intake and stores fat instead of burning it. Moreover, extreme dieting often leads to unhealthy binge-eating behaviors after the diet ends, potentially resulting in significant weight gain. It's crucial to adopt sustainable eating habits that promote long-term well-being rather than short-term fixes.
