To prevent weight gain, how many minutes per week of moderately vigorous activity are recommended?

• A. 100-125 minutes
• B. 150-200 minutes
• C. 225-300 minutes
• D. 300-350 minutes

Answer: (B)

Regular, moderate-to-vigorous activity helps burn calories and supports keeping energy balance in check. For preventing weight gain, the idea is to accumulate enough weekly activity to offset typical daily energy intake while still fitting into a realistic routine. About 150 minutes of moderate-intensity activity each week is the standard baseline; that translates to roughly 30 minutes on five days. Increasing that to a range around 150–200 minutes provides a bit more energy expenditure, making weight maintenance more feasible for many people without demanding an excessive time commitment. The other options either fall short of what’s generally needed to counter typical caloric intake or push beyond what’s necessary for weight maintenance, though higher amounts can be useful for other goals. So, the recommended range for preventing weight gain is about 150–200 minutes per week.
