For the amount of exercise that Charles did for one week in part a, if expending 3500 kcal is equal to a loss of 1.0 lb, how many pounds did he lose?

검증된 단계별 안내

Step 1: Identify the relationship between calories expended and weight loss. The problem states that expending 3500 kcal corresponds to a loss of 1.0 lb.

Step 2: Determine the total number of calories Charles expended during the week. This information should be obtained from part a of the problem.

Step 3: Set up a proportion to calculate the weight loss. Use the relationship: \( \text{Weight Loss (lb)} = \frac{\text{Calories Expended}}{3500} \).

Step 4: Substitute the total calories expended from part a into the formula. Ensure the units are consistent (kcal).

Step 5: Simplify the expression to find the weight loss in pounds. This will give the result for how many pounds Charles lost during the week.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Caloric Deficit

A caloric deficit occurs when the number of calories burned exceeds the number of calories consumed. In the context of weight loss, creating a caloric deficit is essential, as it leads to the body utilizing stored fat for energy. Understanding this concept is crucial for calculating weight loss based on exercise and dietary intake.

Weight Loss Calculation

Weight loss can be quantified by understanding the relationship between calories burned and pounds lost. Specifically, a deficit of 3500 kcal is generally accepted as equivalent to losing 1 pound of body weight. This calculation allows individuals to estimate their weight loss based on their caloric expenditure from exercise.

Exercise Energy Expenditure

Exercise energy expenditure refers to the number of calories burned during physical activity. This can vary significantly based on the type, intensity, and duration of the exercise performed. Accurately estimating this expenditure is vital for determining how much weight can be lost through exercise alone.
