Who should most likely decrease their calorie intake?

The correct choice relates to a situation where an individual may need to decrease their calorie intake due to changes in physical activity levels or energy expenditure. When someone has broken a leg, their mobility is significantly affected, leading to decreased physical activity. As a result, their daily caloric needs may drop because they are not able to burn as many calories through movement and exercise. This decrease in energy expenditure can make it necessary to adjust calorie intake to avoid potential weight gain or other health issues associated with consuming more calories than the body needs.

In contrast, individuals who have begun jogging, are pregnant with twins, or who walk to work are likely to either maintain or increase their calorie needs. For example, jogging is an exercise that burns calories, requiring increased energy intake to fuel the activity. Pregnant individuals, especially those expecting twins, have increased caloric needs to support the growth of the fetuses. Similarly, walking to work adds to daily activity levels, which can also necessitate a higher calorie intake to match energy expenditure.
