Energy 101
The capacity to do work
The energy required to digest, absorb, and metabolize nutrients, including synthesis and storage of protein, fat, and carbohydrates.
What is Obligatory Thermogenesis?
Name two methods to measure energy requirements
Harris-Benedict, Mifflin-St. Jeor equations
Units of measure that corresponds to a person's metabolic rate
What are METS?
Total energy available from food is measure with...
Bomb calometer
Dietary energy intake that is required for growth or maintenance in a person of a defined age, gender, weight, height and level of physical activity
What is energy requirement?
Energy expended during daily living, and the energy expended during sports or fitness exercise
NEAT -
Which type of energy prediction was used for ill patients using parenteral nutrition?
Ireton-Jones equation
How much is 1 MET
1 MET= 1kcal/kg/hr
This is a closed container in which weighed food sample, ignited with an electric spark, is burned within an oxygenated atmsosphere
bomb calorimeter
The energy expended in the activities to sustain normal body function and homeostasis.
What is Resting Metabolic Rate (RMR)?
The net Fat synthesis, carbohydrate intake, or total intake that is excessive indicates an RQ greater or less than 1?
An RQ greater than 1
the average dietary energy intake predicted to maintain energy balance in a healthy adult of a defined age, gender, weight, height, and level of physical activity consistent with good health
Define estimated energy requirements
What affects a person's PAL value?
various activities throughout the day can change this value
Once I am immersed in water, the rise in water temperature causes is used to calculate what?
heat energy generated
Name as many factors as you can affecting energy expenditure (at least 5/7)
Age, body composition, body size, climate, gender, hormonal status, temperature, etc.
Body water from urine, saliva or plasma sampled 10-14 days by two isotopes
What do we test to measure elimination rates?
EER incorporates age, weight, height, gender, and level of physical activity at which age?
At 3 years and older
How to calculate PAL value for one day?
take the sum of activities and add the BEE (1) plus 10% to account for the TEF pg. 24
USDA

What is Direct Calorimetry ?
NO FOOD, NO CAFFEINE, NO NICOTINE, NO EXERCISE for 4 hrs before REE treatment
What is the RULE OF 4's?
Which categories have adjusted energy expenditures?
Children age 3 to 18, infants, pregnant and lactating women.
Which lifestyle has the highest PAL value: Sedentary, low active, active, very active
very active, 1.902.5
Is Sugar made up of a single nutrient? If no, name the nutrient parts
Is an egg made up of a single nutrient? If no, name the nutrient parts
Yes
No. Egg is protein, fat and carb.
