In order to determine the composition of the body with bioelectrical impedance, you should also know __________.
Correct Answer
B. Height, age, weight, and gender
Explanation
To determine the composition of the body with bioelectrical impedance, it is important to consider height, age, weight, and gender. These factors are crucial because they can affect the body's electrical conductivity and impedance. Height is necessary to calculate the body's volume, which is used in the bioelectrical impedance equation. Age, weight, and gender are also important as they can influence the body's composition and metabolism. By considering all these factors, a more accurate assessment of the body's composition can be obtained using bioelectrical impedance.

Andrea eats 2,000 calories a day. She burns 500 during her workouts and 1,000 participating in her normal daily activities. How many more calories does Andrea have to burn to lose weight?
Correct Answer
D. More than 500
Explanation
Andrea eats 2,000 calories a day and burns 500 calories during her workouts and 1,000 calories participating in her normal daily activities. To lose weight, she needs to create a calorie deficit by burning more calories than she consumes. Since she burns a total of 1,500 calories through her workouts and daily activities, she still needs to burn more than 500 calories to create a significant calorie deficit and lose weight. Therefore, the correct answer is "more than 500."

Maintaining a healthy weight comes down to moderation and __________.
Correct Answer
A. Portions
Explanation
Maintaining a healthy weight comes down to moderation and controlling the size of the portions consumed. By being mindful of portion sizes, individuals can ensure they are not overeating and consuming more calories than necessary. Portion control is an important aspect of weight management as it helps to regulate calorie intake and prevent excessive weight gain.
7.
Which statement suits the best about the frequency at which you eat meals?
Correct Answer
D. Eating more, smaller, low-calorie meals is better than eating fewer, large, high-calorie meals.
Explanation
Eating more, smaller, low-calorie meals is better than eating fewer, large, high-calorie meals because it helps to regulate blood sugar levels, boosts metabolism, and prevents overeating. By consuming smaller meals throughout the day, the body is able to efficiently process and utilize the nutrients, leading to a more balanced energy level. Additionally, this approach can aid in weight management as it reduces the likelihood of consuming excessive calories in one sitting.
8.
If cost was not an issue, you would need to do a/an __________ to determine the most accurate information on body composition.
Correct Answer
D. MRI
Explanation
If cost was not an issue, an MRI would be the most accurate method to determine body composition. MRI uses advanced imaging technology to provide detailed information about the body's tissues and organs, including fat, muscle, and bone. It can accurately measure body fat percentage and distribution, making it a reliable method for assessing body composition. However, due to its high cost, MRI is not commonly used for routine body composition assessments and is usually reserved for research or medical purposes.

Christine wants to improve the composition of her body. A few friends have given her advice. Analyze the following sentences to determine which friend gave Christine the best piece of advice.
Correct Answer
B. John says to eat several balanced, low-calorie diets throughout the day and also to exercise regularly.
Explanation
John's advice is the best because he suggests a balanced approach to improving body composition. Eating several balanced, low-calorie diets throughout the day ensures that Christine is getting the necessary nutrients while still maintaining a calorie deficit.
