What are the four forms of energy our bodies use?
What are the three sources of stored energy and in what order are they utilized during periods of fasting?
- 2nd-Adipose fat tissue
- 3rd-Muscle tissue
What three components make up the total energy requirment?
Basal Metabolic Rate
Resting Metabolic Rate
Specific dynamic action or TEF
Thermal effect of food
Total energy expenditure
Total daily energy expenditure
What does BMR measure?
Measure of the energy required to maintain the body at rest (not including digestion)
What does resting metabolic rate measure?
BMR + Digestion
What does thermic effect of food (TEF) measure?
The energy needed to absorb and metabolize a macronutrient (i.e. digestion)
What are some factors that increase BMR?
- lean body mass
- Change in environmental temperature
What are some factors that decrease BMR?
- lack of sleep
what does the respiratory coefficient (RQ) represent?
estimation of the BMR based on carbon dioxide production
RQ = CO2 eliminated/O2 consumed
CHO (carbs) = ?
Fat = ?
Protein = ?
Average mix = ?
RQ = 1 =
- CHO (carbs) = 1.0
- Fat = 0.7
- Protein = 0.8
- Average mix = 0.8-0.85
- RQ = 1 = complete oxidation
What does adaptive thermogenesis do?
Increased total energy expanded in periods of stress
What are three examples of adaptive thermogenesis?
- Extreme cold
What are the two types of natural simple sugars?
What three natural sugars are monosaccharides?
What are the three Disaccharides?
What are complex carbohydrates?
- (Polyglucose molecules)
What types of fatty acids have no double bonds?
Unsaturated fatty acids consist of ?
- Monounsaturated (double bonds)
- Polyunsaturated (Multiple double bonds)
- -omega 3 & 6
What are the characteristics of metabolic pathways?
- Every pathway has a committed step
- Metabolic pathways are regulated
- some metabolic pathways are compartmentalized
