SOLVED EXAM PAPER GRADED A+
◉ Examples of negative energy balance situations.
Answer: during illness or trauma, major burn injury, intentional act
such as dieting to meet a weight loss goal
◉ Our sole source of energy intake is from:.
Answer: food and beverages
◉ Energy can be expended naturally via _____________ , _____________,
and _________________.
Answer: basal metabolism, the thermic effect of food, and
thermogenesis
◉ Energy can be expended intentionally through _______________.
Answer: physical activity (aka exercise)
◉ Two major components of energy expenditure are:.
Answer: basal metabolic rate and physical activity
◉ Basal metabolic rate (BMR).
,Answer: the number of calories used by the body while in a fasting
state and accounts for approximately 60-70% of energy expenditure
◉ BMR varies by person based on factors such as:.
Answer: gender, lean body mass, body size, temperature, age,
nervous system activities, levels of caffeine intake, and tobacco use
◉ BMR males:.
Answer: 1 kcal/kg/hour
◉ BMR females:.
Answer: 0.9 kcal/kg/hour
◉ As we age BMR declines by ______________% per decade so we must
adjust eating habits to prevent weight gain..
Answer: 1-2 %
◉ Thermic effect of food (TEF).
Answer: the energy used for digestion and absorption of food and
accounts for approximately 10% of the calories expended.
◉ larger meals higher in protein result in a higher ________.
Answer: thermic effect of food (TEF)
, ◉ Thermogenesis.
Answer: the ability to regulate temperature and activities such as
fidgeting, maintaining body posture, and shivering. ( energy burned
through this process is very small)
◉ Physical activity.
Answer: accounts for 15-40% of our energy expenditure
◉ Physical activity factors include:.
Answer: body size, fitness level, and actual activity to determine how
many calories are expended
◉ The amount of energy used can be measured both ________________
and ___________________..
Answer: directly and indirectly
◉ Direct calorimetry.
Answer: measures the amount of heat given off the body.
◉ An insulated chamber surrounded by a thin layer of water is used
to measure the amount of heat emitted by the subject in the
chamber. (used infrequently due to complexity and expense).
