Extreme dieting poses several risks, including nutrient deficiencies, muscle loss, and metabolic slowdown. Such diets often eliminate essential food groups, leading to an inadequate intake of vitamins, minerals, and other critical nutrients. This can result in a range of health issues, including fatigue, weakened immunity, and hormonal imbalances. Additionally, extreme calorie restriction can trigger binge-eating behaviors and negatively impact mental health, causing anxiety and depression around food. Sustainable, balanced eating is more effective for long-term health and weight management than extreme dieting approaches.
