Adonis, do you use either of these formulas as a basis to calculate caloric needs:
(1) Harris-Benedict Formula (with BMR based on total body weight)Women:
BMR = 655 + (9.6 X weight in kg) + (1.8 X height in cm) - (4.7 X age in years)
OR
BMR = 655 + (4.354 X weight in lbs) + (4.569 X height in inches) - (4.7 X age in years)
And in case you are wondering, the formula for Men is:
BMR = 66 + (13.7 X weight in kg) + (5 X height in cm) - (6.8 X age in years)
OR
BMR = 66 + (6.213 X weight in lbs) + (12.69 X height in inches) - (6.8 X age in years)
Now that you know your BMR, you can calculate TDEE by multiplying your BMR by your activity multiplier from the chart below:
Activity Multiplier
Sedentary (desk job, with little or no exercise)
= BMR X 1.2
Lightly active (light exercise/sports 1-3 days/week)
= BMR X 1.375
Moderately active (moderate exercise/sports 3-5 days/week)
= BMR X 1.55
Very active (intensive exercise/sports 6-7 days/week)
= BMR X 1.725
Extremely active (intensive daily exercise/sports & physical job or twice per day training for marathon, races, fitness contests, etc.)
= BMR X 1.9
(2) Katch-McArdle Formula (with BMR based on lean body mass)
BMR (men/women) = 370 + (21.6 X lean body mass in kg)
OR
BMR (men/women) = 370 + (9.8 X lean body mass in lbs)
Example:
You weigh 130 lbs. (59.1 kg)
Your body fat percentage is 20% (26 lbs. fat, 104 lbs. lean)
Your lean body mass is 104 lbs. (47.3 kg)
Your BMR = 370 + (21.6 X 47.3) = 1392 calories
To determine TDEE from BMR, you simply multiply BMR by the activity multiplier (which is the same as those used in the Katch-McArdle formula above)
