To progress a weight-loss program, which modification will MOST likely accomplish the weight-loss goal?

• A. Maintain the current walking speed and increase the duration to 30 minutes.
• B. Increase the walking speed and keep the duration at 15 minutes.
• C. Walk 4 days/week and decrease the duration to 10 minutes.
• D. Change from walking 3 days/week to jogging 1 day/week for 20 minutes.

Answer: (D)

Weight loss hinges on creating an energy deficit, so the modification that boosts calories burned per session—and thus weekly expenditure—tends to be most effective. Jogging raises exercise intensity, which increases calories burned per minute compared with walking. A 20-minute jog delivers more metabolic demand and contributes to a larger workout energy expenditure (and a greater afterburn) than simply extending a walking session or adding more short walks. Even though you’d be exercising less frequently, the higher intensity session produces a greater overall boost to weekly energy expenditure, making it the most impactful choice for moving toward a weight-loss goal.
