Rapid weight loss can cause heart strain, potentially leading to irregular heart rhythms (arrhythmias), which can be life-threatening.
Electrolyte imbalances
Rapid weight loss and severe caloric restriction can disrupt the body's electrolyte balance, causing heart and muscle function issues and potentially leading to cardiac arrest.
Malnutrition
Extreme diets can lead to severe malnutrition, weakening the immune system, loss of lean muscle mass, impaired organ function, and organ failure.
Dehydration
Rapid weight loss often results in significant fluid loss, leading to dehydration, which can negatively impact kidney function and overall health.
Mental health issues
Extreme diets and rapid weight loss can increase or trigger mental health conditions such as depression, anxiety and eating disorders.
