Which intervention is the best evidence-based behavioral solution for an underweight person who reports poor appetite and early satiety?

• A. Increase eating frequency with small, energy-dense snacks and add healthy fats to meals (e.g., nut butters, oils) while combining with resistance exercise to promote lean mass gain and improve appetite over time.
• B. Advise the person to restrict fluids during meals to thin gastric contents and then attempt to consume a single very large meal each day, since extreme intermittent overeating is the most sustainable method to overcome satiety quickly.
• C. Recommend avoidance of all exercise because any physical activity will further suppress appetite and therefore prevent weight gain regardless of its type or timing.
• D. Instruct the person to rely solely on stimulant medications to increase metabolic rate so they will require more calories and therefore naturally increase intake without dietary planning.
