TESTED QUESTIONS AND CORRECT
ANSWERS ALREADY PASSED RESOURCE
●● positive energy balance
Answer: Calorie intake is greater than calorie expenditure.
●● when does positive energy balance occur
Answer: overeating, low activity, or both
●● What happens to calories consumed in excess over time?
Answer: Over time, the calories consumed in excess of expenditure
contribute to weight gain
●● negative energy balance
Answer: Calorie intake is less than calorie expenditure.
●● when does negative energy balance occur
Answer: ▪decreasing calorie intake,
▪increasing physical activity (PA), and
(preferably) both
,weight loss
●● calorie
Answer: ▪Unit by which energy is measured
▪Technically, a calorie is actually a kilocalorie of kcal.
●● how to estimate the total number of calories in a food or diet
Answer: ▪The total number of calories in a food or diet can be estimated
by multiplying total grams of carbohydrates, protein, or fat by the
appropriate number of calories per gram.
●● where do calories come from
Answer: carbohydrates, protein, fat, and alcohol
●● ▪4/4/9 Rule
Answer: ▪Protein: grams x 4= calories from protein
▪Carbohydrates: grams x 4= calories from carbs
▪Fat: grams x 9= calories from fat
▪Calculate total: add calories from all
▪Adjust for servings eaten: multiply total calories by the number of
servings you consumed
, ●● how is basal energy metabolism measured?
Answer: under strict labratory conditions, fasted, upon awakening, no
movement
●● how is resting metabolic rate measured?
Answer: less restrictive and more practical - allowing for daily activities
and moderate fasting
●● basal metabolism
Answer: ▪Caloric cost of staying alive or the amount of calories required
to fuel the involuntary activities of the body at rest after a 12-hour fast.
●● how many calories does the BMR account for
Answer: ▪Basal metabolic rate (BMR) accounts for approximately 60%
of total calories expended.
▪The less active a person is, the greater the proportion of calories used
for basal energy expenditure (BEE).
●● involuntary body activities
Answer: ▪maintaining body temperature and muscle tone, producing and
releasing secretions, propelling the gastrointestinal tract, inflating the
lungs, and beating the heart
●● ▪Basal Energy Expenditure (BEE)
