1. Name at least 2 examples of when negative energy balance occurs.:
During illness or trauma that affects appetite or intake, healing,
2. Name at least 2 examples of when positive energy balance is
necessary.: Pregnancy and growth spurts in childhood and adolescence 3.
match the following words to their definitions:
basal metabolic rate
physical activity
Thermic effect of food
Thermogenesis: Basal metabolic rate - number of calories used by the body
while in a fasting state
Physical activity - accounts for 15-40% of energy expenditure and depends upon
body size, fitness level, and actual activity
Thermic effect of food - energy used for the digestion and absorption of what we
ingest accounts for about 10% of the calories expended
,Thermogenesis - accounts for a very small amount of energy
4. describe the difference between negative and positive energy balance.:
Positive energy balance occurs if more energy (calories) are consumed than
expended,
Negative energy balance occurs if fewer calories are consumed than are expended
