Question

Quizplus · Accepted Answer

Consuming a high-calorie, high-protein liquid formula daily would provide John with the necessary nutrients and calories to help him gain weight. This option is more effective than increasing intake of potassium-rich foods, reducing energy expenditure, or increasing fluid intake, as these approaches do not directly address the issue of underweight and may not provide sufficient calories and nutrients for weight gain.
