Create a short justification (best choice) for advising against weight-loss strategies that rely exclusively on prolonged use of laxatives or diuretics.

They are optimal for long-term fat loss because removing water fast permanently reduces body weight and improves metabolic health.

They are harmless when used daily for months because the body adapts by increasing micronutrient absorption.

They produce fluid and electrolyte losses rather than sustained fat loss, increase risk of nutrient deficiencies and organ dysfunction, and do not produce maintainable healthy weight — safer sustainable lifestyle and dietary changes are recommended.

They selectively target visceral adipose tissue and thus are superior for reducing cardiometabolic risk compared with calorie reduction or exercise.
