What is the Katch McArdle equation?
What is the Katch McArdle equation?
To apply the Katch-McArdle formula, you need to know your lean body mass: BMR = 370 + (21.6 × Lean Body Mass [kg]) It is also possible to calculate your BMR using this formula if you know: Your body fat percentage, because then lean body mass can be calculated as follows: LBM = (Weight [kg] × (100 – Body Fat %) / 100.
How accurate is the Katch McArdle formula?
This formula tends to be slightly more accurate than other formulas which are based on total body weight. It is based on the basic Mifflin-St Jeor equation that will base the equation on Fat Free Mass (FFM) or Lean Mass. This is more accurate for those who know their body fat percentage.
Which calorie equation is most accurate?
Of these equations, the Mifflin-St Jeor Equation is considered the most accurate equation for calculating BMR with the exception that the Katch-McArdle Formula can be more accurate for people who are leaner and know their body fat percentage.
How do I calculate my basal calorie needs?
Calculate Basal Metabolic Rate Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
How much weight will I lose based on calorie intake?
In general, if you cut about 500 calories a day from your usual diet, you may lose about ½ to 1 pound a week. But this can vary depending on your body, how much weight you want to lose, your gender and activity level.
What is the rule of thumb for BMR?
One imprecise, rule-of-thumb guideline for estimating BMR is to multiply healthy weight (in pounds) by 10 for women and 11 for men. For example, a 130-pound woman expends approximately 1300 cal/day on BMR (130 pounds × 10 cal/pound = 1300 calories).
