Which statement best summarizes the practical implication of set point theory for a person who has recently lost substantial weight?

• A. Because set point is fixed and immutable, attempting any behavioral strategies after weight loss is futile and should be abandoned.
• B. Set point theory suggests once weight is lost the body will always remain at that new lower weight without behavioral changes, so maintenance strategies are unnecessary.
• C. Because physiology may drive increased appetite and reduced energy expenditure after weight loss, long-term maintenance often requires sustained behavioral strategies (e.g., tracking, activity) rather than assuming spontaneous stabilization.
• D. Set point theory only applies to genetic animals and has no relevance to human weight management, meaning dietary modifications alone will always succeed.
