1.
The American Heart Association recommends limiting your saturated fat consumption to less than ___ percent of your daily calories.
Correct Answer
A. 7%
Explanation
The American Heart Association recommends limiting saturated fat consumption to less than 7% of daily calories because consuming high amounts of saturated fat can increase cholesterol levels and the risk of heart disease. By keeping saturated fat intake low, individuals can maintain a healthier cardiovascular system and reduce the risk of developing heart-related problems.
2.
Which three food items typically contain high amounts of saturated fats?
Correct Answer
C. Bacon, cheeseburger, whole milk
Explanation
Bacon, cheeseburgers, and whole milk typically contain high amounts of saturated fats. Saturated fats are commonly found in animal-based products, and bacon, cheeseburgers, and whole milk are all examples of such products. These foods are known to contribute to higher levels of cholesterol and are often associated with an increased risk of heart disease.
3.
Muscle weighs more than fat.
Correct Answer
B. False
Explanation
False! A pound is a pound (of feathers, glass, Jell-O—you name it). But because a pound of fat takes up about four times the space of muscle tissue, it’s possible to look and feel trimmer even if body weight remains the same.
4.
To lose one pound of fat, a person has to burn roughly _____ calories.
Correct Answer
D. 3,500
Explanation
To lose one pound of fat, a person has to burn roughly 3,500 calories. This is because one pound of fat is estimated to contain around 3,500 calories. Therefore, in order to create a calorie deficit and lose weight, a person needs to burn more calories than they consume. By creating a deficit of 3,500 calories, they can lose approximately one pound of fat.
5.
How much water should you be drinking during a workout?
Correct Answer
B. 8 ounces every 15-20 minutes
Explanation
During a workout, it is important to stay hydrated to maintain optimal performance and prevent dehydration. The recommended amount of water to drink during a workout is 8 ounces every 15-20 minutes. This ensures that you are replenishing the fluids lost through sweat and keeping your body hydrated. Drinking when you feel thirsty may not be sufficient as thirst is not always an accurate indicator of hydration levels. It also depends on how much you sweat, but the general guideline is to drink 8 ounces every 15-20 minutes.
6.
Inactive people who do not strength train will lose ___ pound(s) of muscle per year, starting after age 20.
Correct Answer
B. 1/2
Explanation
Inactive people who do not strength train will lose 1/2 pound of muscle per year, starting after age 20. This means that if someone does not engage in regular strength training exercises, they can expect to lose half a pound of muscle mass annually. This highlights the importance of incorporating strength training into one's fitness routine to prevent muscle loss and maintain overall muscle health.
7.
What is your "metabolic rate"?
Correct Answer
A. The rate at which you burn calories
Explanation
The metabolic rate refers to the rate at which the body burns calories. It is a measure of how efficiently the body converts food into energy. This rate can vary from person to person and is influenced by factors such as age, gender, body composition, and activity level. Therefore, the correct answer is "The rate at which you burn calories."
8.
In general, the more muscle and less fat you have, the higher your metabolic rate.
Correct Answer
A. True
Explanation
The statement is true because muscle tissue is more metabolically active than fat tissue. This means that it requires more energy to maintain and results in a higher metabolic rate. Therefore, individuals with more muscle and less fat tend to have a higher metabolic rate compared to those with less muscle and more fat.
9.
Which of the following can boost your metabolic rate?
Correct Answer
C. A high-protein diet
Explanation
A high-protein diet can boost your metabolic rate because protein requires more energy to digest and process compared to fats and carbohydrates. This is known as the thermic effect of food. When you consume protein, your body needs to work harder to break it down, which results in an increase in calorie burn. Additionally, protein helps to build and maintain lean muscle mass, which can also contribute to a higher metabolic rate. Therefore, a high-protein diet can potentially increase your metabolism and aid in weight management.
10.
What is your "metabolism"?
Correct Answer
C. The processes your body uses to convert or use energy
Explanation
The term "metabolism" refers to the processes in our body that convert or use energy. It encompasses various biochemical reactions that occur within our cells to break down nutrients and produce energy. These processes include digestion, absorption, transportation, and utilization of nutrients. Metabolism plays a crucial role in maintaining essential bodily functions such as breathing, circulating blood, regulating body temperature, and repairing cells. It also determines the rate at which we burn calories, which can impact weight management. Therefore, the correct answer is "The processes your body uses to convert or use energy."
11.
Muscle is about ___ times more efficient at burning calories than fat, even when at rest.
Correct Answer
A. 3
Explanation
Muscle is about 3 times more efficient at burning calories than fat, even when at rest. This means that even when the body is at rest, muscle burns more calories compared to fat. This is because muscle is an active tissue that requires energy to function and maintain itself, whereas fat is a storage tissue that does not require as much energy. Therefore, having a higher proportion of muscle in the body can help increase the metabolic rate and calorie burn, even during periods of inactivity.
12.
Approximately ___ of American adults are sedentary.
Correct Answer
A. 25%
Explanation
Approximately 25% of American adults are sedentary. This means that a quarter of the adult population in America leads a sedentary lifestyle, characterized by a lack of physical activity and prolonged sitting or inactivity. Sedentary behavior has been linked to various health issues such as obesity, heart disease, and diabetes. It is important to promote regular physical activity and reduce sedentary time to improve overall health and well-being.
13.
Which of the following is a whole grain?
Correct Answer
A. Popcorn
Explanation
A whole-grain includes the entire grain seed or kernel. Examples of whole grains are popcorn, wild rice, buckwheat, bulgur, millet, oatmeal, quinoa, rolled oats, brown rice, and whole-grain barley, rye, and wheat. These foods may be eaten by themselves or found as ingredients in such foods as bread, cereals, and crackers. Multigrain bread usually is not 100% whole grain.
14.
Which of the following is NOT true about water?
Correct Answer
C. A good rule of thumb is to drink 10-12 glasses of water a day
Explanation
There is no evidence to show that drinking 10-12 glasses of water is necessary. Generally, nutritionists recommend we follow the "8x8" rule, which is to drink eight 8-ounce glasses of water per day. Drinking more water does indeed boost metabolism - especially if your glass is icy cold. Your body must work to warm the water up, burning a few extra calories in the process. As for other benefits of water, 85% of your brain tissue is water, which means that if you're dehydrated, both your body and your mind will be stressed.
15.
Which of these foods has the most calories?
Correct Answer
C. Two ounces of candy corn (approximately 32 pieces)
Explanation
Two ounces of candy corn (approximately 32 pieces) = 207 calories
