Lifetime Weight Control Practice Exam

To understand how long it takes Doug to burn one pound of body fat, it's important to recognize that approximately 3,500 calories equate to one pound of fat. The rate at which Doug burns calories during his physical activities or exercises will determine the duration needed to reach that 3,500-calorie deficit.

If Doug is currently burning calories at a specific rate, you can calculate the time required by dividing 3,500 by the number of calories he burns per minute. For example, if Doug burns 10 calories per minute, it would take him 350 minutes (3,500 ÷ 10) to burn off one pound of body fat.

Since the correct answer is 350 minutes, this indicates that, based on Doug’s current calorie-burning rate, this duration is necessary for him to achieve the caloric deficit needed for weight loss equivalent to one pound of fat. Calculating these estimates is vital in planning weight management strategies.
