3. One activity that the writer suggests will probably increase one's caloric need is
Answer: C
Walking up stairs will probably increase one's caloric need.
Engaging in activities such as walking up stairs is an effective way to increase caloric expenditure. This activity requires more energy than typical movements, thereby raising one's overall caloric needs.
A) Eating half-portions in restaurants.
While eating half-portions may help in reducing overall caloric intake, it does not directly increase caloric need. Instead, it focuses on caloric restriction rather than activities that enhance energy expenditure.
B) Decreasing trans-fat intake.
Reducing trans-fat intake is a dietary choice aimed at improving health, but it does not inherently increase caloric need. The focus here is on the quality of calories consumed, rather than the quantity of calories burned through activity.
C) Walking up stairs.
Walking up stairs is a physical activity that significantly increases heart rate and energy expenditure, thereby raising caloric need. It is a form of exercise that effectively utilizes various muscle groups and burns more calories compared to sedentary behaviors.
D) Using low-calorie recipes.
Using low-calorie recipes is aimed at reducing caloric intake rather than increasing caloric need. This option emphasizes the consumption of fewer calories, which is contrary to the idea of boosting energy expenditure through physical activities.
Conclusion
Walking up stairs stands out as the only option that actively increases caloric expenditure through physical activity. In contrast, all other options either focus on reducing caloric intake or improving dietary choices without enhancing energy needs. Thus, walking up stairs is definitively the best choice for increasing one's caloric need.
