Download a copy of this page to your computer (.rtf)

1. Find your estimated resting metabolic rate.

Your weight in pounds __________ divided by 2.2 = ________ kg

Your height in inches ___________ multiplied by 2.54 = _________ cm

Put these numbers into the appropriate Harris-Benedict equation to estimate your resting energy needs:

Women

655 + (9.56 x _________ kg)	__________
add (1.85 x _______ cm)	+ __________
subtract (4.68 x _____ age)	- __________	= __________ Daily calories w/o activity

Men

66.5 + (13.8 x ________ kg)	__________
add (5 x ________ cm)	+ __________
subtract (6.76 x _______age)	- __________	= __________ Daily calories w/o activity

2. Add energy expended in physical activity on a typical day.

These figures will come from your activity journal sheets where you figured out your energy expenditure in activity for each day. Write in the number of calories you expended in activity for each day on the corresponding line below.

Daily Calories Expended in Physical Activity	Day 1 _______
	+ Day 2 _______
	Sum of 2 days expenditure ________
Divide Total Expenditure sum by 2, = Avg. of 2-day expenditure ___________

3. Estimated total daily energy expenditure:

Resting Metabolic rate from section 1	____________
Add Average Daily Activity Expenditure from section 2	+ ____________
TOTAL Energy Expenditure =	_____________

4. Estimated dietary analysis caloric intake:

Day 1	_____________
+ Day 2	_____________
Sum of 2 days intake	_____________
Divide the 2-day sum by 2, = Avg. of 2-day expenditure	____________

Energy Balance: Avg. energy exp. _ Avg. caloric intake

Was your caloric intake from your dietary analysis close to your estimation of your energy expenditure (+/- 200 calories)? If so, you are in energy balance and will likely maintain your current weight.

Interpret your daily caloric intake, as compared to your energy expenditure, in 1-2 sentences:
