UNIT 6: CHAPTER 25
NUTRITION, METABOLISM AND TEMPERATURE REGULATION
Define Basal Metabolic Rate (BMR) and describe 3 major uses of metabolic energy in the
body
...
o A unit of ATP is produced in cells at about the same rate as it is used up
...
o BMR is determined by measuring the oxygen consumption of a person who is awake
and restful and has not eaten for 12 hours
...
825 (because each liter of oxygen we use results in 4
...
o In the average person, basal metabolism accounts for about 60% of energy
expenditure
...
o A number of factors can affect BMR
...
Therefore, people with well-developed
muscles have a higher BMR than other people
...
o Metabolic energy in the body is used in 3 ways: (1) for BMR, (2) for the thermic
effect of food and (3) for muscular activity
...
o The thermic effect of food: This refers to energy involved in the digestion and
absorption of food
...
All of these events require energy and this is
referred to as the thermic effect of food
...
o Muscular activity consumes about 30% of the body’s energy
...
o The number of kilocalories expended in an activity depends on the amount and
duration of muscular work
...
o To maintain weight, the daily input of energy should equal the metabolic
expenditure of energy: otherwise a person will gain weight
...
o If you maintain your body weight, you are said to be in a calorie balance, where the
energy input equals your energy output
...
o If we consume MORE calories than we expend, this leads to weight gain
...
This tells us that adjusting the kilo-caloric input is an important way to
control body weight
...
This needs to be
done within means as our bodies require energy to preform basic functions
...
o Let us consider the types of nutrients we eat to maintain a healthy weight
...
For
example: to convert dietary fat into body fat, 3% of the energy in the dietary fat is
used, leaving 97% of fat for storage as dietary fat
...
This leaves just
77% as body fat
...
o On an important note: Consuming too few calories (less than 1000 a day) decreases
BMR and may lead to a decrease in muscle mass and will have an undesired effect
...
