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

• A. They are optimal for long-term fat loss because removing water fast permanently reduces body weight and improves metabolic health.
• B. They are harmless when used daily for months because the body adapts by increasing micronutrient absorption.
• C. 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.
• D. They selectively target visceral adipose tissue and thus are superior for reducing cardiometabolic risk compared with calorie reduction or exercise.

Answer: (C)
