Harris-Benedict Equation* for Caloric Intake Requirements**
Males:
(Calories/Day)
Resting Energy Expenditure = (66.47 +
6.237 x Weight (lbs.) + 12.7 x Height (inches.) - 6.775 x Age) x Activity
Factor
where Activity Factor = 1.0 for
Bedrest
= 1.2 for
Ambulatory/Sedentary
= 1.375 for Light Exercise/Sports 1-3
Days/Week
= 1.55 for Moderate Exercise/Sports 3-5
Days/Week
= 1.725 for Hard Exercise/Sports 5-7
Days/Week
= 1.9 for Very Hard Daily Exercise/Sports
Females: (Calories/Day)
Resting Energy
Expenditure = (655.1 + 9.56 Weight + 1.85 Height - 4.68 Age) X
Activity Factor
My Numbers
My
weight: 128 lbs. = 58.2 kg.
My
height: 5' 7" = 170 cms.
My Activity
Factor = 1.375?
My
Age
= 75
My Calorie Needs= 2,000?
For someone (not me!) at 320
lbs. 2,892 kCal./day
For someone (not me!) at 256 lbs. 2,412 kCal./day
For me at
160 lbs. 1,692 kCal./day
For me at 144 lbs.
1,572 kCal./day
For me at 128
lbs.: 1,452 kCal./day
For me at 124 lbs.: 1,422 kCal./day
For someone (not me!) at 80 lbs.
1,092 kCal./day
My calorie requirements at a 10% weight reduction are
92.8% what they are at full weight... i. e., 7.1% less
My calorie
requirements at a 20% weight reduction are 85.6% what they are at full weight...
i. e., 14.2% less.
My calorie requirements at a 25% weight reduction are
82.1% what they are at full weight... i. e., 17.9% less.
My calorie
requirements at a 50% weight reduction would be 65.4% what they are at full
weight... i. e., 33.9% less.
My calorie requirements at 200% of 160 lbs. (320
lbs.) would be 1.66 times what they would be at baseline weight (160
lbs.)..
Blood Pressure vs. Weight: Drops 1 mm. Hg. (both
systolic and diastolic) per kg. lost
Blood Pressure and Exercise: (4 mm. Hg. systolic, 3 mm.
diastolic) (meta-analysis of 54 trials involving 2,419 adults.
Aerobic exercise lowers B. P. by 11 mm.
systolic and 9 mm. diastolic
