✔✔20-30%

✔✔skinfold measurement
,The percentage of body fat
✔✔is normally higher in women than in men
Which of the health hazards listed below is not associated with serious
underweight?
✔✔hyperlipidemia
Which of the effects listed below is not a result of a low-carbohydrate diet?
✔✔deficiency of ketone bodies
What is the approximate daily basal metabolic energy needs of a 50-kg
woman?
✔✔1000-1300 kcal
When energy-yielding nutrients are consumed in excess, which one(s) can
lead to storage of fat?
✔✔fat, carbohydrate, and protein
What is the body's most likely response to surplus dietary fat?
✔✔The excess fat will almost all be stored as body fat.
After the first day or so of fasting, which of these compounds is most
depleted in the body?
✔✔glycogen
What type of diet is associated with the development of ketosis?
✔✔low carbohydrate
,Weight loss in the first few days on a low-carbohydrate diet is MOST likely
due to the loss of which of the following body components?
✔✔water
What is the approximate percentage of Canadian adults with a BMI over

✔✔88 cm
A cup (250 ml) of 2% milk contains 12 grams of carbohydrates, 8 grams
of protein, and 5 grams of lipids. Calculate the physiological fuel value of
the milk.
✔✔The physiological fuel value of the milk is 125 kilocalories (calories).
, carbohydrate: 4 cal/g × 12 g = 48 kcal
protein: 4 cal/g × 8 g = 32 kcal
lipids: 9 cal/g × 5 g = 45 kcal
Total: 125 kcal
A one-cup serving of kidney beans contains 343 kcals, 14 grams of
protein, and 56 grams of carbohydrate. What percentage of the energy
comes from fat?
✔✔The proportion of energy from fat is 18.4%.
energy from carbohydrate = 4 × 56 = 224 kcals
energy from protein = 4 × 14 = 56 kcals
energy from carbohydrate + protein = 224 + 56 = 280
Therefore, energy from fat = 343 − 280 = 63 kcals
Percentage of energy from fat = (63 × 100)/343 = 18.4%
Ketone bodies are abnormal metabolites produced during fasting.
✔✔[False] Ketone bodies are normal metabolites, but may be produced in
a quantity greater than the body can metabolize when an individual is
fasting, and so may have deleterious effects.
Indirect calorimetry of a food involves the measurement of oxygen
consumed and carbon dioxide produced by the body.
✔✔[False] Oxygen consumption and carbon dioxide production by the
