BIOD 121 (Portage): Module 3 questions with verified
answers
"thrifty" metabolism Ans✓✓✓ fewer calories than normal are used to maintain
body function (more prone to weight gain)
1 pound in a week is equivalent to : Ans✓✓✓ 500 extra calories a day
3 key components to weight loss and weight maintenance: Ans✓✓✓ - control of
calories
- physical activity
- behavior modification
Activity Level: Ans✓✓✓ sedentary: no exercise (men 1.00/ women 1.00)
low activity: exercises the equivalent of walking 2 miles per day 3-4 mph (men
1.11/ women 1.12)
active: exercises the equivalent of walking 7 miles per day (men 1.25/ women
1.27)
Very active: exercises the equivalent of walking 17 miles per day (men 1.48/
women 1.45)
Alcohol consumption, smoking, and a diet with a high glycemic load also
contribute to this form of obesity: Ans✓✓✓ android obesity (apple shape)
Amphetamines: Ans✓✓✓ stimulate the central nervous system and burn calories
(used short term as they can develop a dependency)
, 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) Ans✓✓✓ Direct calorimetry
Android obesity Ans✓✓✓ is defined by fat being stored in the abdominal area,
yielding the "apple" body shape.
Anthropometrics: Ans✓✓✓ the science of measuring the proportions and size of
the body, offers a more practical method to determine body fat composition.
As we age BMR declines by ______________% per decade so we must adjust
eating habits to prevent weight gain. Ans✓✓✓ 1-2 %
Basal metabolic rate (BMR) Ans✓✓✓ the number of calories used by the body
while in a fasting state and accounts for approximately 60-70% of energy
expenditure
Behavior modification strategies: Ans✓✓✓ chain breaking, stimulus control,
cognitive restructuring, contingency management, self-monitoring
Behavior modification: Ans✓✓✓ describes how certain factors (behaviors) can
prevent us from reaching our weight loss goals.
Bioelectrical impedance Ans✓✓✓ based on the principle that water conducts
electricity and fat resists electricity. As muscle is primarily composed of water, an
instrument with electrodes is connected to the body and a painless low energy
electric current is sent through the body. Since fat resists electricity, higher levels
of resistance indicate a higher percentage o body fat.
