Choice A reason: Limiting high-calorie supplements to between meals is not a good strategy for managing anorexia while receiving radiation therapy because it can reduce the appetite and intake of regular meals, which are more nutritious and balanced. High-calorie supplements should be used as an addition to, not a replacement for, regular meals.

Choice B reason: Avoiding overeating during 'good' days is not a good strategy for managing anorexia while receiving radiation therapy because it can cause discomfort, nausea, or vomiting, which can worsen anorexia and affect the tolerance of radiation therapy. Eating should be based on hunger and satiety cues, not on good or bad days.

Choice C reason: Consuming nutrition-dense foods first is a good strategy for managing anorexia while receiving radiation therapy because it can ensure adequate intake of calories, protein, vitamins, and minerals, which are essential for healing and recovery. Nutrition-dense foods are those that provide high amounts of nutrients per serving, such as eggs, cheese, nuts, beans, and meat.

Choice D reason: Eating hot foods rather than cold foods is not a good strategy for managing anorexia while receiving radiation therapy because it can irritate the mouth and throat, which may be inflamed or sore due to radiation therapy. Cold foods are more soothing and refreshing for the mouth and throat, such as ice cream, yogurt, smoothies, and popsicles.
