Which of the following is responsible for roughly two-thirds of the energy needed to keep the body functioning?
Thermogenesis
Basal metabolism
Thermic effect of food
Associated with lower risk of heart disease =
Visceral fat
Subcutaneous fat
Significantly contributes to heart disease and diabetes =
Visceral fat
Subcutaneous fat
Central obesity =
Visceral fat
Subcutaneous fat
Fat around the hips and thighs =
Visceral fat
Subcutaneous fat
1.Fat is stored in (a) tissue.
What is basal metabolism?
The energy required for physical activity
The energy expended during digestion
The energy required to maintain basic body functions at rest
The energy derived from food breakdown
What is ATP (adenosine triphosphate)?
A vitamin essential for energy metabolism
A coenzyme that assists metabolic reactions
The high-energy compound that powers cellular activities
A protein that builds muscle
What happens when energy intake exceeds energy expenditure?
Weight loss
Energy balance
Positive energy balance, leading to fat storage
Negative energy balance, leading to muscle loss
What is the main role of enzymes in metabolism?
Providing energy for reactions
Facilitating metabolic reactions
Acting as nutrients in the body
Storing excess energy
Which food type is considered the most satiating?
High-fat foods
High-protein foods
Sugary foods
High-calorie beverages
What is the relationship between waist circumference and central obesity?
Waist circumference is unrelated to central obesity.
A waist circumference of >40 inches (men) or >35 inches (women) indicates central obesity.
Waist circumference is only important for obese individuals.
Waist circumference measures body composition directly.
What is the energy yield from alcohol metabolism?
4 kcal/g
7 kcal/g
9 kcal/g
0 kcal/g, as alcohol is not a nutrient
What happens to alcohol when it enters the body?
It is stored in the liver as energy reserves.
It is oxidized to acetaldehyde and then to acetate.
It is directly converted to glucose for energy.
It is expelled entirely through the breath and urine.
What is the physiological response to the need for food, primarily triggered by the hypothalamus?
Satiety
Satiation
Hunger
Appetite
Which of the following is an example of a negative energy balance?
Consuming more calories than expended
Equal calorie intake and expenditure
Energy intake is less than energy expenditure
Rapid weight gain due to overeating
What is the main component of energy expenditure that is the most variable and influenced by activity?
Basal metabolism
Physical activity
Thermic effect of food
Digestion
What is the thermic effect of food?
Energy needed to digest, absorb, and metabolize food
Energy used during physical activity
Energy required for maintaining basic body functions
Energy stored as body fat
Which of the following accurately describes central obesity?
Fat stored under the skin around the hips and thighs
Fat stored within the abdominal cavity around internal organs
Fat distributed evenly throughout the body
Fat accumulating only in the lower body
What is the main consequence of an energy intake exceeding expenditure?
Weight stability
Weight loss
Fat storage in the body
Increased thermogenesis
What are the three main components of the body’s energy expenditure?
Hunger, satiation, and satiety
Basal metabolism, physical activity, and the thermic effect of food
Protein, carbohydrates, and fats
Appetite, digestion, and excretion
