I am 68(170cm) inches tall, 200(90.9kg) pounds and 41 years old. When I used CT's calculator I came in at about 1800 calories per day.
From CT's Prime Time entry:
Your BMR is a function of your size, sex and age. It is also influenced by your metabolic status (hypo or hyperthyroid state for example). We can calculate that BMR with the following formulas (by Harris-Benedict):
BMR = 66 + (13,7 x weight in kg) + (5 x height in cm) - (6.8 x age)
So for a 30 years old bodybuilder of 220lbs (100kg) on 5?11? (178cm) it comes up to:
BMR = 66 + (13,7 x 100kg) + (5 x 178cm) ? (6,8 x 30)
BMR = 2122 calories per day
