|
The body's generation of heat
|
thermogenesis
|
|
|
The rate of energy use for metabolism under specified conditions- after 12 hour fast and restful sleep without any physical activity or emotional excitement
|
Basal Metabolic Rate
|
|
|
Similar to BMR, but with less strict criteria for recent food intake and physical activity
|
Resting Metabolic Rate
|
|
|
the energy needed to maintain life when a body is at complete digestive, emotional, and physical rest
|
Basal Metabolism
|
|
|
an estimation of the energy required to process food
|
Thermic effect of food
|
|
|
Factors affecting estimating energy requirements
|
gender, growth, age, physical activity, and body composition and size
|
|
|
EER Requirement Calculation for men 19 years and older
|
662 - 9.53 x age in years + physical activity factor x [(15.91 x weight in kg) / (539.6 x height in meters)]
|
|
|
EER Requirement Calculation for women 19 years and older
|
354 - 6.91 x age in years + physical activity factor x [9.36 x weight in kg) / (726 x height in meters)]
|
|
|
Body Mass Index Calculation
|
weight in kg / height in meters squared OR weight in lb x 703 / height in inches squared
|
|
|
BMI below 18.5
|
underweight
|
|
|
BMI 18.5-24.9
|
healthy weight
|
|
|
BMI 25-29.9
|
overweight
|
|
|
BMI over 30
|
obese
|
|
|
a formula that uses your BMR and then applies an activity factor to determine your total daily energy expenditure (calories)
|
Harris Benedict Equation
|
|
|
Male and female estimates for basal energy needs
|
Men: 24 kcal per kg per day, Women: 23 kcal per kg per day
|
|
|
To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows: sedentary = BMR x1.2, lightly active = BMR x1.375, moderately active = BMR x 1.55,
very active = BMR x 1.725, extra active = BMR x 1.9 |
Harris Benedict Equation
|
|
|
% ideal body weight that indicates level of malnutrition
|
Waterlow Equation
|
|
|
fat stored within the abdominal cavity in association with the internal abdominal organs, as opposed to the fat stored directly under the skin
|
intra-abdominal fat
|
|
|
excess fat around the trunk of the body
|
central obesity, abdominal fat, or upper-body fat
|
|
|
an anthropometric measurement used to asses a person's abdominal fat
|
waist circumference
|
|
|
Health risks of upper-body fat (apple shape)
|
more common in men and is closely associated with heart disease, stroke, diabetes, hypertension, and some cancers
|
|
|
Health risks of lower-body fat (pear shape)
|
more common in women and is not usually associated with chronic diseases
|
|
|
A method of assessing body fat that estimates body fat by using a caliper to gauge the thickness of a fold of skin on the back of the arm or below the shoulder blade and comparing them to standard measures
|
Fatfold measures
|
|
|
A method of assessing body fat that measures body density by weighing a person on land and then again while submerged in water. An equation using the two measurements determines total body density
|
Hydrodensiometry
|
|
|
A method of assessing body fat that uses a low-intensity electrical current. The measurement of electrical resistance is used in a calculation to estimate percentage of body fat
|
Bioelectrical impedance
|
|
|
A method of assessing body fat that estimates body composition by having a person sit inside a chamber while computerized sensors determine the amount of air displaced by the person's body
|
Air displacement plethysmography
|
|
|
A method of assessing body fat that uses two low-dose x-rays that differentiate among lean body mass, fat tissue and bone tissue
|
Dual energy x-ray absorptiometry (DEXA)
|
|
|
Calculation for water requirement: standard outpatient
|
20-40 cc per kilogram body weight
|
|
|
Calculation for water requirement: standard inpatient
|
100 cc per kilo for the 1st 10 kilos + 50 cc per kilo for the next 10 kilos + 20 cc per kilo after 20 kilos.
|
|
|
Low and high water requirement for standard outpatient weighing 81 kilos (calculate)
|
1630 cc - 3240 cc per day
|
|
|
Water requirement for standard inpatient weighing 81 kilos
|
2420 cc per day
|
