Katch-Mcardle Formula: Calculate Your Basal Metabolic Rate, Estimate BMR
Calculate your basal metabolic rate using the katch-mcardle calculation, or estimate your bmr.
The formula for Katch-Mcardle uses a different equation to calculate your BMR. It does not take sex into consideration, but readily adjusts to varying body types. If you know your lean body mass percentage (or your percentage of body fat), then you can apply this information to get a more accurate BMR.
For example, a 170-pound person with 20% body fat would have 136 lbs. of lean muscle mass and 34 lbs. of fat.
♥ [170 lbs. x 20% body fat = 34], then [170 lbs. – 34= 136 lbs. of lean muscle mass]
Then calculate your BMR by using the following equation and multiplier.
370 + [9.79759519 x lean muscle mass] = BMR
370 + [9.79759519 x 136] = 1702.47295
Katch-McArdle Equation and TDEE
|Little to no exercise||BMR x 1.2|
|Light exercise (1-3 times per week)||BMR x 1.375|
|Moderate exercise (3-5 times per week)||BMR x 1.55|
|Heavy exercise (6-7 times per week)||BMR x 1.725|
|Extremely heavy exercise (more than 7 times per week + physical job)||BMR x 1.9|
