DLA 33 and lecture 51 Flashcards
What is resting metabolic rate (RER)?
The energy expended to carry out normal body functions
What factors impact the RER?
age, gender, temperature, injury factor, etc.
How can the total energy expenditure (TEE) be estimated?
BMR = 24 kcal per 1kg
RMR = BMR + 10%
TEE = RMR / 75%
The diet requires what percentage of each macronutrient?
carbs = 40 percent proteins = 30 percent Fats = 30 percent
How to convert from percentage to grams in regard to carbs?
0.40 x 2000 = 800 / 4 = 200g
Dietary doses of DHA and EPA reduce?
- Arrhythmia
- heart rate
- blood pressure
omega 3’s
What is a high and low glycemic index?
high = anything above 70
low = anything below 55
What are the essential amino acids?
PVT TIM HALL
What is a respiratory quotient?
Determines what macromolecule is being used for metabolism
RQ = 1 = carbs
RQ = 0.84 = protein
RQ = 0.71 = fats
What does ghrelin do?
peptide hormone that is produced by the stomach in order to simulate hunger
short-term
cholecystokinin and PYY?
produced by the small intestine to simulate short-term fullness
short-term
What does leptin do?
peptide hormone produced by adipose tissue
decreases appetite and desire to eat
Overeating and chronic high fructose consumption may lead to leptin resistance and obesity.
Kwashiorkor?
protein deficiency due to malnutrition
Marasmus?
deficient in calories due to malnutrition
How to estimate muscle/ fat ratio?
- triceps skinfold (body fat)
- mid-arm muscle circumference (muscle mass)
- Bioelectric impedance analysis (body fat)
- DEXA scan (body fat)
