Which of the following multi-component maintenance plans best integrates adjusted calorie targets, behavioral strategies, and activity with physiologic justification?

• A. Increase daily calories above pre-loss intake to counter perceived metabolic slowdown, eliminate all snacking entirely without behavioral monitoring, and substitute all physical activity with daily sauna sessions for passive calorie burn.
• B. Restrict calories well below new maintenance and avoid exercise to minimize appetite increases, rely on willpower alone for behavioral control, and avoid planning any routine to maintain flexibility.
• C. Use a single strategy of intermittent fasting intermittently and assume this will automatically maintain weight without attention to composition of diet, resistance exercise, or behavioral tracking.
• D. Set daily intake at the individual's new maintenance estimate, implement resistance training twice weekly to preserve lean mass and resting energy expenditure, keep a daily food log and practice mindful eating to reduce unconscious excess intake, and use stress-management techniques to mitigate stress-induced overeating.

Answer: (D)
