3. Which statement suits the best about the frequency at which you eat meals?

Eating a lot of high-calorie meals will maintain your weight if you are sedentary.

Eating a few high-calorie meals every day will help you gain weight.

Eating a lot of low-calorie meals will help you lose weight.

Eating more, smaller, low-calorie meals is better than eating fewer, large, high-calorie meals.

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.

4. 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?

Less than 500

Less than 100

At least 100

More than 500

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."

5. Which of the following statements is NOT a weight loss myth?

Effective and lasting weight loss means that weight gained over time should be lost over time.

To lose weight, you must consume fewer calories than your present rate.

To keep weight off, you need to alter your habits only until the weight is lost.

Fad diets are a good way to quickly and permanently reduce your weight.

The statement "Effective and lasting weight loss means that weight gained over time should be lost over time" is not a weight loss myth because it accurately reflects the concept of sustainable weight loss. Losing weight in a healthy and sustainable manner involves making long-term changes to one's lifestyle and habits, rather than relying on quick fixes or fad diets. This statement emphasizes the importance of gradual weight loss and maintaining a healthy weight over time.

6. The average adult eats about 4,000 calories a day.

True

False

The statement is false because the average adult does not eat 4,000 calories a day. The recommended daily calorie intake for adults varies depending on factors such as age, gender, weight, and activity level. On average, adult men need about 2,500 calories per day, while adult women need about 2,000 calories per day. Therefore, the statement is incorrect.

7. In order to determine the composition of the body with bioelectrical impedance, you should also know __________.

BMI, age, and gender

Height, age, weight, and gender

Height, gender, weight, and percentage of body fat

Age, gender, and lean muscle mass

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.

8. To set your intensity level, you need to __________.

Increase your resting heart rate by increasing the weights you lift each week

Use your maximum heart rate, which is determined by subtracting age from 220

Exercise for a minimum of 60 minutes in each session

Determine what it is by subtracting your age from 2,000 calories

To set your intensity level, you need to use your maximum heart rate, which is determined by subtracting age from 220.

10. If cost was not an issue, you would need to do a/an __________ to determine the most accurate information on body composition.

Skin fold measurement

Hydrostatic weighing

BMI

MRI

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.
