IMPORTANT CONVERSIONS:
*WEIGHT:
1 kg = 1000 g = 2.2 lbs
454g = 1 lb= 16 oz
28.4 g = 1 oz
1 g = 1000 mg
1 mg = 1000 µg
*VOLUME:
1 L = 1000mL = 1 qt = 4c
240 mL = 1 c = 8 oz
5 mL = 1 tsp
15 mL = 1 T = 3 tsp
16 T = 1 c
30 mL = 1 fl oz
*LENGTH:
2.54 cm = 1 in
*NUTRITION:
1 lb = 3500 kcal
1 g CHO = 4 kcal
1 g Protein = 4 kcal
1 g Fat = 9 kcal
*BIOCHEMICAL:
Glucose: .0555 x mg/dL = mmol/L
Lipids (TC, LDL, HDL): .0259 x mg/dL = mmol/L
Lipids (TG): .011 x mg/dL = mmol/L
ESTIMATING CALORIE NEEDS:
*RESTING METABOLIC RATE (RMR):
MIFFLIN-ST. JEOR
(10 x wt. in kg) + (6.25 x ht. in cm) – (5 x age) + 5
WOMEN
(10 x wt. in kg) + (6.25 x ht. in cm) – (5 x age) – 161
* Multiply RMR by AF of 1.3 for sedentary people or higher AF for active individuals
*EMPERICAL FORMULAS:
OBESES/VERY INACTIVE
10 – 12 kcal/lb
> 55 YO, ACTIVE WOMEN, SEDENTARY MEN
13 kcal/lb
ACTIVE MEN, VERY ACTIVE WOMEN
15 kcal/lb
THIN OR VERY ACTIVE MEN
20 kcal/lb
*HARRIS-BENEDICT:
*Classic formula for basal needs but over and underestimates needs
NORMAL – OVERWEIGHT INDIVIDUALS
66.47 + (13.75 x wt in kg) + (5.0 x ht in cm) – (6.76 x age)
WOMEN
655.10 + (9.56 x wt in kg) + (1.85 x ht in cm) – (4.68 x age)
OBESE INDIVIDUALS (>130% IBW)
Adjusted body weight = (CBW – IBW) x .38 + IBW
WOMEN
Adjusted body weight = (CBW – IBW) x .32 + IBW
* Now multiply Basal Energy Needs by the suitable activity or stress factor
ACTIVITY DESCRIPTION (if healthy)
ACTIVITY FACTOR (AF)
Chair or bed bound
1.2 * BEE
Seated work and little or no leisure activity
1.4 – 1.5 * BEE
Seated work with little strenuous activity
1.6 – 1.7 * BEE
Standing work
1.8 – 1.9 * BEE
Strenuous work or highly active activities
2.0 – 2.4 * BEE
30 – 60 min strenuous activity (4-5 xs/wk)
AF + .3
CLINICAL STATUS (use if sick)
STRESS FACTOR * BEE

1.0 – 1.1
Multiple trauma
Severe Infection
1.2 – 1.6
Peritonitis
1.05 – 1.25
