Answers 2026 | High-Yield Review | Graded A+
1. The purpose of brown fat cells is _.
to regulate body temperature by either heating or cooling the body
to burn fat and thereby generate body heat
to provide energy to the body during extended periods without eating
to store fat
to provide a source of energy for extended activity
2. The 'normal' range of percentage body fat for men is:
12-22%
0-4%
5-11%
30-34%
23-29%
3. If a 60-year-old person has a significantly lower BMR than they did at 30, how
might this affect their weight management strategy?
Their weight management strategy will remain unchanged.
They can maintain the same caloric intake as before.
They may need to reduce their caloric intake to avoid weight gain.
They should increase their caloric intake to gain weight.
4. Describe how environmental factors can impact weight management.
, Environmental factors are solely determined by genetic factors.
Environmental factors such as availability of healthy foods and
opportunities for physical activity can significantly influence weight
management.
Environmental factors only affect weight in children.
Environmental factors have no impact on weight management.
5. Serving sizes on the Nutrition Facts label are_
often too small to meet nutrient needs
different for different brands of the same food product
often larger than what Americans typically eat today
often smaller than what Americans typically eat today
6. A body mass index (BMI) is a measure of fatness. An ideal BMI for adults is
what range?
Between 18.5 and 24.9
Between 25.0 and 29.9
Between 30.0 and 37.5
Between 12.8 and 18.4
7. Following BMI index indicates a person is underweight?
< 18.5 kg/m^2
25-29.9 kg/m^2
> 30 kg/m^2
18.5- 24.9 kg/m^2
,8. What is the primary function of brown fat cells in the body?
Protein synthesis
Energy storage
Heat production
Hormone regulation
9. What is the BMI range that is considered to indicate a healthy weight?
18.5 to 24.9
30 to 34.9
25 to 29.9
15 to 18.4
10. Describe the significance of waist circumference measurements in assessing
obesity.
Waist circumference measurements indicate overall body weight.
Waist circumference measurements help assess abdominal fat,
which is a risk factor for chronic diseases.
Waist circumference measurements are only relevant for athletes.
Waist circumference measurements are not related to health risks.
11. What is a common characteristic of novelty fad diets?
They focus solely on increasing physical activity.
They often promise quick weight loss with little effort.
They are based on balanced nutrition and exercise.
They require a long-term commitment to lifestyle changes.
, 12. According to BMI, a person is considered obese if
25 < BMI < 29.9
BMI ≥ 30
18.5 < BMI < 24.9
BMI < 18.5
13. What is the definition of contingency management in the context of behavior
modification?
A method of measuring body fat percentage.
A technique for assessing energy balance.
A type of fad diet focused on rapid weight loss.
A behavioral strategy that uses rewards and consequences to
reinforce desired behaviors.
14. Describe how bioelectrical impedance analysis can provide insights into a
person's body composition.
Bioelectrical impedance analysis measures the resistance of body
tissues to electrical currents, which helps estimate fat and lean
mass.
Bioelectrical impedance analysis requires a blood sample to
determine body fat percentage.
Bioelectrical impedance analysis uses sound waves to visualize body
tissues.
Bioelectrical impedance analysis calculates body composition based
on height and weight alone.
