To help with weight loss, how many calories should be expended during aerobic activity within 40 minutes?

The correct choice indicates that expending 400-480 calories during aerobic activity over the course of 40 minutes can significantly aid in weight loss efforts. This range aligns with current fitness guidelines that suggest that moderate to vigorous intensity aerobic exercise can help create a substantial caloric deficit, which is crucial for weight loss.

Typically, the number of calories burned during exercise depends on various factors, including body weight, exercise intensity, and duration. The range of 400-480 calories suggests a higher intensity workout, such as running or high-intensity interval training, which can be effective for maximizing calorie expenditure in a relatively short time frame. Engaging in aerobic activities at this level over 40 minutes can help individuals meet their daily caloric deficit goals when combined with proper dietary management, thereby facilitating weight loss.

While lower caloric expenditure options might appear feasible, they may not provide the same level of impact on weight loss efficiency, especially when adhering to a structured exercise regime intended for this purpose. Higher expenditure levels can align with the fitness goals of individuals seeking more aggressive weight loss or improved cardiovascular fitness.
