What is Metabolism?
-All chemical reactions that go on in cells
-When chemical bonds break, energy is released
What is ATP?
is energy
How do you Direct measurer the amount of energy in food?
bomb calorimeter
Where is the energy source glycogen primarily stored?
liver and muscle
Where is the primary location of Glucose or lipids?
body fluids
Where is triglycerides primarily stored?
adipose tissue
Where is protein primarily stored?
muscle
What is fat storage and what does it require?
Storage of triglycerides in fat cells

Requires a supply of
Glucose
and
Fatty Acids
What is energy balance? and what are ways to shift energy balance?
Comparison of energy in & energy out
-Kcal from food = kcal expended

Ways to shift energy balance
-Consume fewer kcal
-Use more kcal
How many kcal= does it take to burn 1 pound of fat (adipose tissue)?
3500 kcal = 1 lb of adipose tissue
What are the equations to maintain, gain and loose weight due to Energy balance?
Energy in = Energy out
Weight maintenance
Energy in > Energy out
Weight gain
Energy in < Energy out
Weight loss
What is Basal metabolism (BMR)?
and what % of energy does the body use to maintain this Components of Energy Expenditure?
-(50-65%) is how much body uses of energy
-Energy to maintain life at rest
-Similar to resting metabolic rate (RMR)
what % of energy does the body use to maintain this Components of Energy Expenditure?
(30-50%)
What is the Components of Energy Thermic effect of food (TEF) ?
and what % of energy does the body use to maintain this Components of Energy Expenditure?
-(10%)
Energy for digestion, absorption, transport, and storage of nutrients
What is the Components of Energy Adaptive thermogenesis?
and what % of energy does the body use to maintain this Components of Energy Expenditure?
-(variable; <10%)
-Adjustments such as cold environment, overfeeding, trauma
What are Factors that affect BMR?
-Lean body mass (muscle, bone)
More LBM . . . higher BMR
-Surface area
Larger surface area, higher BMR
Gender
Men > women
Temperature (fever)
Physiological processes
