Basal Metabolism
Minimum amount of energy expended in a fasting state to keep a resting, awake body alive in a warm quiet environment.
60-70% in a sedentary person
Let’s see how basal metabolism contributes to energy needs.Slide6
Basal Metabolism
2.2 lb for every kg, convert weight
200 / 2.2 = 90 kg
Rough estimate of basal metabolism:
0.9 kcal/kg per hour1.0 kcal/kg per hour 90 x 1 = 90 kcal/hr
90 x 24 = 2160 kcalSlide7

Basal Metabolism
Factors that Decrease:
Low Energy Intake
10-20%
150 to 300 kcal/dayLoss of Lean Body Mass1-2% past age of 30 Physical Activity PreservesSlide9
Physical Activity
Increases basal metabolism by 25 – 40%.Varies widely among individuals
Varies among activities.
Examples: stairs vs elevator, walking vs driving, standing vs sitting.
Evaluation: leisure timeSlide10
Digestion, Absorption & Processing
Thermic Effect of Food (TEF)
Sales Tax: 5 – 10%
For every 100 calories of basal metabolism, 105 – 110 kcal.Food CompositionProtein (20-30%)Carbohydrate (5-10%)Fat (0-3%)Slide11
Thermogenesis
Increase in non-voluntary physical activity triggered by cold conditions or overeating.
Fidgeting, Shivering, Maintenance of Muscle Tone, Upholding Body PostureSlide12
Concept
Energy Balance = Input + Output
The Body Uses Energy for 4 main purposes:
Basal Metabolism (60-70%)
Physical Activity (20-30%)Digestion, Absorption, & ProcessingThermogenesis
