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

Because set point is fixed and immutable, attempting any behavioral strategies after weight loss is futile and should be abandoned.

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.

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.

Set point theory only applies to genetic animals and has no relevance to human weight management, meaning dietary modifications alone will always succeed.
