Progesterone to estradiol ratio The progesterone to estrogen ratio calculator estimates the value of a parameter used to assess hormone imbalance and converts progesterone and estradiol units. It should be noted that resting metabolic rate is not the same as basal metabolic rate or BMR. There is a slight difference between the two, in that a resting metabolic rate estimation includes consideration for calories burned to digest food, whereas basal metabolic rate does not.
For this reason, your resting metabolic rate is typically considered to be a more reliable estimation of your calorie burn during rest than basal metabolic rate, because your body is usually digesting some amount of food at any given moment. For example, to perform a typical basal metabolic rate measurement in a laboratory setting a subject would need to have fasted for 12 to 14 hours, whereas no fasting is required for a resting metabolic rate measurement.
This calculator is based on the widely used and accepted Harris-Benedict equations for determining basal metabolic rate BMR , with a modification incorporated to account for calories burned to support digestion of food. The formulas are shown below:. Walking Calorie Burn Calculator. VO2max Calculator. The formula we use in this calculator is different for males and females. It takes into account age years , weight kg , and height stature in cm.
The equation for males is:. In order to manually calculate your RMR you need to perform the necessary unit conversions, then replace the respective values in the formula for your gender.
Our tool does this automatically, as required. Some call into question the established formulas used in many RMR calculations, for example Owen et al.
However, this conclusion is based on only 44 women aged and it is unclear how representative a sample they are for the general population.
More recent and much larger studies like Wright et al. However, their statistical analysis, sadly, gives no indication of the direction of the bias. A much larger study by Marra et al.
