The best answer to the question: Which strategy will best help Karen maintain her health, would be: Eat nutrient-dense food and engage in regular physical activity.

Explanation:

Because Karen´s BMI (Body Mass Index) is within the normal limits for her age, and Karen´s body as at a stage of development that requires nutrients, one way to help her be able to eat as she likes, but still maintain her healthy weight and a balanced body, without gaining weight, would be to eat nutrient-rich foods and exercize. The reason is that research has shown that nutrient-rich foods will not only provide all that is needed by the body, but also, they will ensure that metabolism is always active and that fats and carbs are not stored unnecessarily, but used as energy producers, thus preventing weight gain. Also, by providing just what the body needs, these foods cut down on possible cravings and binge eating, thus further lowering the possibility of eating disorders. Physical activity, furthermore, will enhance the use of carbs and lipids as energy, instead of fat stores, and will maintain the metabolism at a healthy rate, as well as will strengthen the cardiovascular and respiratory systems, as well as the musculo-skeletical, systems for Karen.
