Modest weight loss (2-3 kg per month) requires which minimum weekly duration of moderate-to-vigorous physical activity?

• A. Less than 150 minutes
• B. 150-199 minutes
• C. More than 150 minutes
• D. 225-420 minutes

Answer: (C)

Weight loss comes from creating a weekly energy deficit, and exercise is a key way to raise energy expenditure. For a modest loss of about 2–3 kg per month, you need to push beyond the basic health recommendation. That means doing more than 150 minutes of moderate-to-vigorous activity each week. The 150-minute mark is the threshold for general health benefits, but exceeding it increases weekly calories burned and supports steady weight loss. Staying under 150 minutes is typically not enough to drive weight loss, while going a bit above it provides the minimal amount needed to see the intended effect.
